Research and Innovations

Introduction

Scientific precision – in the service of quality of life

Prof. Dr. Dr. Hermann F. Sailer is regarded worldwide as one of the defining figures in oral and maxillofacial surgery. Through surgical innovation, international research, and academic vision, he has significantly advanced the field and helped countless people regain not only the aesthetics and function of their faces but also their dignity.

His scientific work has always been guided by the goal of harmonizing functionality and aesthetics of the human face.

In doing so, he combined clinical experience with modern research, setting new standards in reconstruction, implantology, and functional surgery.

Many of his developments – from novel surgical techniques to biomaterial-based therapies – have been incorporated into international guidelines and continue to shape teaching and clinical practice worldwide.

Thus, his name stands not only for medical excellence but also for the close connection between science and practice – always with the patient at the center.

Research Focus Areas

Prof. Dr. Dr. Hermann F. Sailer mastered like few others the art of linking science with surgical practice. His research led not only to fundamental insights but also to concrete surgical methods that have shaped the field of oral and maxillofacial surgery worldwide. Many of these innovations are now part of international guidelines and are considered standards in clinical practice and teaching.

  • Reconstructive facial surgery with lyophilized cartilage – introduction of freeze-dried donor cartilage as a substitute material to avoid additional harvesting of the patient’s own tissue.
  • Dental implants in atrophic maxilla – combination of implantation with simultaneous jaw reconstruction.
  • Bone Morphogenetic Proteins (BMPs) – use of bone-generating proteins for bone regeneration without autologous grafts.
  • Resorbable osteosynthesis materials – development of self-dissolving fixation systems made from lactic acid polymers.
  • Treatment of cleft lip and palate – development of interdisciplinary concepts for functional and aesthetic rehabilitation (the Sailer Protocol).
  • Surgery for craniofacial anomalies – innovative surgical procedures to correct complex malformations of the skull and face.
  • Surgical treatment of obstructive sleep apnea syndrome (OSAS) – establishment of the technique of bimaxillary counterclockwise rotation advancement to expand the airways.
  • Theory of the “Anteface” – anthropological studies on facial proportions and the formulation of a modern standard of beauty.
  • Distraction osteogenesis of the maxilla and mandible.
  • CT-based airway analyses – new radiological methods for planning and evaluating the success of complex procedures.

Innovations

Prof. Dr. Dr. Hermann F. Sailer is among the leading innovators in oral and maxillofacial surgery. His work was always driven by the search for solutions – not only to medical challenges but also to questions of aesthetics, functionality, and quality of life.

In doing so, he combined clinical experience with scientific curiosity and interdisciplinary openness.

His innovations range from new surgical techniques and biomaterial-based developments to theoretical concepts that fundamentally reshaped the understanding of beauty, proportion, and harmony.

Many of these ideas have been incorporated into international guidelines and continue to influence both modern facial surgery and the aesthetic self-perception of entire generations.

The New Ideal of Beauty: “Anteface”

Based on decades of research and anthropological analysis, Prof. Dr. Dr. Hermann F. Sailer developed the concept of the “Anteface” – a modern ideal of beauty that differs significantly from traditional notions. Instead of static symmetry and formal perfection, it emphasizes a forward-oriented, dynamic facial profile that unites expressiveness, authenticity, and functional harmony.

With this theory, Sailer broke away from conventional norms of aesthetics.

Beauty is no longer defined by rigid systems of measurement but understood through the interplay of form, function, and individuality. The “Anteface” combines aesthetic considerations with medical and functional relevance – for example, in the treatment of dysgnathia, craniofacial anomalies, aesthetic-functional reconstructions, and even in the therapy of sleep apnea syndrome.

The insights formulated by Sailer continue to shape not only aesthetic and reconstructive surgery but also extend far beyond medicine – into fields such as design, art, anthropology, and media aesthetics. Beauty is reinterpreted: not as absolute symmetry, but as the expression of a unique identity in which naturalness and proportionality are key.

The “Reverse Facelift”

At a time when facial rejuvenation procedures relied almost exclusively on tightening the skin, Prof. Dr. Dr. Hermann F. Sailer developed an entirely new concept: the “Reverse Facelift.” Instead of putting the skin under tension – often resulting in an unnatural, mask-like appearance – he placed the original bone structure at the center of treatment. In this procedure, the upper and especially the lower jaw are advanced forward through a rotational spatial movement. The result is not only an aesthetic improvement – creating the Anteface or Hyperanteface – but also an expansion of the oropharyngeal airway, which enhances oxygen intake and contributes to rejuvenation.

Particularly in the midface, the natural bony foundation is purposefully reconstructed and built up. This creates a youthful harmony that radiates from within, rather than being merely superficially concealed.

The outcome is an authentic, refreshed appearance that preserves natural expression and respects individual identity. With this method, Sailer set new standards in combining functionality, naturalness, and longevity – ushering aesthetic facial surgery into a new era.

Cure for Obstructive Sleep Apnea

For a long time, obstructive sleep apnea was considered an incurable condition. Millions of people suffered from nightly breathing interruptions, chronic fatigue, and a significantly increased risk of cardiovascular disease. Treatment was usually limited to aids such as breathing masks (CPAP) or other symptomatic measures.

Prof. Dr. Dr. Hermann F. Sailer developed a surgical approach that eliminates the root cause. Using the technique he established – bimaxillary counterclockwise rotation advancement – the upper and lower jaws are repositioned in such a way that the upper airways remain permanently expanded. This prevents nighttime collapse and surgically cures sleep apnea.

This procedure marked a paradigm shift: away from purely treating symptoms and toward lasting healing. For patients, it means not only restful sleep but also a significant improvement in health, performance, and quality of life.

“It's simply fascinating. Not only how Professor Sailer does it, but what he achieves with it.”

Reports from Patients Who Have Successfully Undergone Surgery

Report by Dr. Köster, the patient.

He himself is a doctor from Germany and previously underwent CPAP mask therapy, followed by an unsuccessful sleep apnea surgery in Germany.
He is always willing to contact other patients to provide information.

Here are his conclusions:

  1. The clinical picture of obstructive sleep apnea can be treated surgically using a counterclockwise bimaxillary rotational osteotomy according to Prof. Sailer.
  2. None of the conservative treatments offered, including the CPAP mask, are effective in reducing the risk of cardiovascular complications.
  3. The bimaxillary repositioning osteotomy without rotation, as offered by many oral and maxillofacial surgeons, is not suitable for reproducibly curing obstructive sleep apnea.
  4. As the inventor of this surgical method, Prof. Sailer in Zurich is widely recognized as having the best expertise and reputation as the most experienced—and at the same time most cautious—surgeon in Europe.
  5. The only surgeon in Germany who offers this surgical procedure and has many years of experience is a doctor from Heidelberg. A significant proportion of the procedures performed by this doctor are associated with complications—some of them serious—such as nerve damage, loss of correction, and the need for follow-up surgeries, as was the case with me. Conservative estimates suggest that procedures performed by this doctor that result in complications account for between 20 and 40 percent of the cases operated on.
  6. In conclusion, based on the above considerations and in accordance with the WZW criteria, it is recommended that every patient with obstructive sleep apnea who requires surgical treatment have the procedure performed exclusively at Prof. Sailer’s Oral and Maxillofacial Surgery Clinic in Zurich.

Successful sleep apnea surgery despite the family doctor's skepticism

Sleep Apnea Surgery 2021

A letter from the patient to his previous doctor, who was rather skeptical about the surgery!

Dear Doctor (from Winterthur, Switzerland)

Contrary to your critical stance toward Prof. H. Sailer, I underwent jaw surgery performed by Prof. H. Sailer and Prof. J. Malina on June 21, 2021.

  • I am more than satisfied with the surgery performed at the Sailer Clinic.
  • I no longer have sleep apnea.
  • My high blood pressure has gone down.
  • I need two fewer hours of sleep per night.
  • I’m no longer tired for no reason.
  • My airways feel clearer.
  • I’ve lost 8 kg since the surgery.
  • Aesthetically speaking, my face has come out on top.
  • I still notice a very slight tension between my lower jaw and my lips

Since I only have basic insurance, I had to pay a significant portion of the surgery costs myself.

However, the benefits of the surgery are priceless.
Professor Hermann Sailer has performed surgery on over 1,000 skulls. For many years, he served as chief of orthodontics at the University Hospital in Zurich and developed this surgical procedure. You can see the awards he has won on Wikipedia. Dr. Malina is also a highly qualified and personable doctor. The Sailer Clinic places a very high priority on transparency with patients. The way patients are treated is excellent.

I recommend that you visit the Sailer Clinic to see for yourself.
Prof. Sailer would certainly allow you to observe one of his surgeries.

Perhaps afterward you’ll recommend the Sailer Clinic to patients who have as much trouble tolerating masks as I do.

Best regards,
Rudolf Pfeiffer

Patient Mr. Müller describes his experience to us 6 months after his surgery

Cured of sleep apnea in 2022 following surgery

M. Müller, 36 years old, Zurich
For as long as I can remember, I’ve struggled with fatigue in my daily life, a lack of motivation, and a low sex drive, and my loud snoring made it impossible for others in the house to sleep. After spending a night in a sleep lab and having the data analyzed, I was diagnosed with sleep apnea, characterized by breathing pauses lasting up to 41 seconds and nighttime oxygen saturation levels that sometimes dropped to 85%. The subsequent treatment for the condition involved a CPAP mask, which I could only wear intermittently throughout the night and which severely restricted my mobility.

Luckily for me, a friend told me about Professor Sailer’s clinic and his jaw rotation method. From the very beginning, I was welcomed warmly and openly by Professor Sailer’s friendly team.

Throughout the entire process, I received personal and professional guidance; I felt motivated to cure my sleep apnea once and for all through surgery, rather than treating it with a mask. In my opinion, it is this combination of professionalism and compassion that sets Professor Sailer apart. At every stage, I felt taken seriously, understood, and in good hands.

In February 2022, after lengthy consultations and meticulous planning—in which I was always involved—the time came for the surgery. It was a landmark moment that would improve my quality of life beyond imagination. The rotation of my jaw allowed my windpipe to be widened from 6 mm to over 20 mm in diameter. A quick math note: this means over 11 times more cross-sectional area! Today, I wake up feeling refreshed every morning, breathe only through my nose at night, no longer snore, and can feel even in my daily life how my body is getting enough oxygen. I feel a physical energy that was almost overwhelming at first. My mental state is much more balanced; I’m more patient and significantly more productive at work. My metabolism is much faster; even 9 months after the surgery, I’m still steadily losing weight and can feel how my body is changing for the better thanks to the extra oxygen.

I am infinitely grateful to Professor Sailer and his team. My life has taken on a new quality that I could never have dreamed of. At 36, I feel more energetic and fit than ever.

Thank you very much.

A patient shares his story in 2022, after being cured of sleep apnea

Sleep Apnea Surgery in 2017

A patient reports in 2022, after being cured of sleep apnea:

Dear Dr. Sailer,

Dear Professor Sailer,

We, too, would like to join the many others in congratulating you on receiving the Lifetime Achievement Award for your life’s work.

We often think back to March 8, 2017, when we first visited your clinic and received a sobering diagnosis: “severe obstructive sleep apnea” with its resulting health consequences. Then, on March 24, 2017, I had surgery with Jürgen. Suddenly, in a way that was completely unbelievable, a whole new way of life opened up for me—one that continues to this day. You said, “I will heal you!”—and that very promise has come true. Thank you so, so much once again!

We’re doing great! Karin has since gotten a cat and feels most at home here. I, Jürgen, work out three times a week and also get around a lot in the Wörthersee, Plattensee, and Chiemsee regions.

One last thing! The Berlin-Brandenburg Regional Social Court ordered the health insurance company to pay the rates applicable for the surgery in Germany. Admittedly, it was just a drop in the bucket. Despite all that, thanks to your help, we’ve gained something much more valuable: good health! We believe that’s far more important than money!

We wish you both continued happiness and good health!

Rotation, Advancement, and Operation—February 2021

Mr. Phillip Bucher underwent surgery for sleep apnea (rotational mandibular repositioning osteotomy) after no other treatment methods were effective.

On February 24, 2021, I underwent jaw surgery with Dr. Professor Sailer to treat very severe sleep apnea. I had tried several different approaches to manage my sleep apnea, but none of them had worked. Even losing 12 kg hadn’t helped. My oxygen saturation was still below 70% SpO2, with 89 breathing pauses per night, even though I slept on my stomach. I didn’t even dare to sleep on my back anymore because I couldn’t breathe at all.

My wife had sleepless nights and would keep shaking me while I was half-asleep until I could breathe again; she was afraid I would stop breathing altogether.

Dr. Professor Sailer is a true professional among surgeons; my sleep apnea has disappeared completely, and my snoring has stopped as well. There are no visible scars, and the shape of my face has improved.

From start to finish, all consultations and appointments were highly professional. I am very satisfied and would like to express my heartfelt thanks to Dr. Professor Sailer, his very kind wife, Dr. Sailer, and the entire team at the Sailer Clinic. My contact information, including my cell phone number, may be shared for reference purposes without further consultation.

Surgery in May 2020 due to mask intolerance

A sleep apnea patient who underwent surgery reports the following after his procedure:

My pulmonologist didn’t give me much hope in that regard.

I wasn’t satisfied with the CPAP therapy using the machine and mask. While the machine prevented me from having any more episodes of apnea at night, I didn’t notice any other positive effects. That’s why I kept searching online for alternatives and found Professor Sailer. My family doctor referred me to the clinic, and I immediately felt at ease and, above all, that my problem was being taken seriously. After detailed, thorough, and—above all—very pleasant consultations and preliminary examinations (sleep lab, X-rays, etc.), I received my diagnosis.

-Severe OSAS, increasing intolerance to a CPAP mask, narrow airways, insufficient forward growth of the upper and lower jaws, and impaired nasal breathing.

That was reason enough for me to have surgery performed by Professor Sailer and his outstanding team on May 27, 2020. It’s been a few weeks since the surgery now; my sleep apnea is gone, breathing is much easier, and I get an incredible amount more air and oxygen whenever I exert myself. The relief is immense, and I never could have imagined that the difference would be so enormous. The healing process is going very well, and I’m moving forward with a positive outlook.

I would like to take this opportunity to thank Professor Hermann F. Sailer and his team for the exceptionally warm and welcoming atmosphere and for the improved quality of life I have gained.

Best regards

Post-Surgery Report 2020, Mr. Rohrer

Partner Shares Her Experience with Her Partner’s Sleep Apnea Surgery

My partner suffered from severe sleep apnea. It was becoming increasingly life-threatening—loud snoring and long pauses in breathing at night, and the fear of a stroke or heart attack every time he went to bed…

We came across Prof. Sailer more by chance. And that was the best thing that could have happened to us!

My partner and I are incredibly grateful for this! The care was top-notch from the very beginning, with very friendly and attentive staff—I highly recommend them in every way! My initial fears and concerns were completely put to rest, and the result exceeded my expectations in every way.

The surgery completely cured my partner!

The apnea is completely gone—no more episodes, no more snoring! My partner finally wakes up feeling refreshed again and has boundless energy. He has literally been given a new lease on life…

We’re just so happy and grateful!

The Right Step Toward a New Life

On January 27, 2020, Professor Sailer and his team performed surgery on me using the Advanced Bimaxillary Rotation Method.

Since then, a ordeal that lasted more than 20 years has, thankfully, come to a happy end, and this procedure has given me a new lease on life.

In the late 1990s, I was diagnosed with severe sleep apnea, which was treated surgically in 1998 with laser surgery at the Charité. Unfortunately, the treatment’s success was short-lived. The same symptoms (severe breathing pauses and snoring) returned after a little over a year. Since I was still relatively young, I tried to counteract the effects of sleep apnea by exercising a lot and leading a healthy lifestyle. I was more or less successful at this, to the point that my wife, after wearing earplugs for several years, insisted on sleeping in separate bedrooms. This was followed by several unsuccessful visits to well-established ENT specialists, who told me that there was no cure for my sleep apnea other than CPAP therapy. So I went back to the sleep lab and was subsequently fitted with a CPAP machine. Unfortunately, I couldn’t tolerate it, and I resigned myself to the fact that obstructive sleep apnea is a condition that cannot be cured in my case.

Years of declining health followed (obesity, high blood pressure, depression, heart rhythm disorders, gastrointestinal problems, constant fatigue), which I didn’t automatically attribute to sleep apnea, so I resigned myself to my fate.

Then, in June 2019, I came across the website of Prof. Sailer, who claimed to be able to cure this disease.

During my initial examination in Zurich in July 2019, I was treated with great professionalism and kindness, and the cause of my condition was explained to me. At that time, the diameter of my trachea was just over 2 mm. After consulting with Prof. Dr. Sailer, it quickly became clear to me that my other symptoms were also attributable to this condition. I then decided to have the procedure performed in Zurich, even though my private health insurance would not cover the costs. As mentioned earlier, the procedure was performed on January 27, 2020, by Professor Sailer and his team. After two days as an inpatient at the clinic—where I received excellent care—I moved to a hotel and was soon able to return home with my wife. Since then, I’ve lost just under 20 kilograms, my blood pressure has normalized, I’m no longer tired, I only need an average of 5 hours of sleep, and I’m extremely energetic. On top of that, I no longer snore, and I can highly recommend Prof. Dr. Sailer’s clinic.

For me, a new chapter in my life began on January 27, 2020.

Dear Professor, “Thank you so much for the gift”

Sleep Apnea Surgery, May 2019: Mr. Möller Reports

Germany, May 2020

One year after his sleep apnea surgery, Mr. Wolfgang Möller writes:

Good morning, Prof. Sailer, Dr. Sailer, and the Sailer team. We hope everyone is in good health and that the virus has given you all a wide berth.

A year has flown by, and I’m glad I took the step to have sleep apnea surgery last May. My quality of life has completely improved since the procedure, known as bimaxillary repositioning osteotomy.

We can enjoy our lives to the fullest again.

The pandemic is now adding its own twist to things. We’re slowing down, and this more relaxed pace allows us to notice so many more things that were previously hidden from view. Long walks we take with the dog. Really taking nature in. Marveling at two rainbows right next to each other in the rain, truly witnessing nature’s reawakening once again… Soaking up all the things together that had been neglected in recent years due to my health issues. It’s wonderful.

Once the situation allows, we’ll definitely come visit you again.

We would like to thank you once again for the excellent service and wish everyone a wonderful time.

Stay healthy.

Best regards

Wolfgang and Marina Möller

January 2019, 2 days after his sleep apnea surgery:

Mr. Martakos came in for a follow-up visit on the second day after his surgery and spontaneously shared how he was doing.

For me, the „Rotation Advancement“ procedure developed by Prof. Sailer is:

Regaining My Health, Vitality, and Joy of Life

My problems were:

  • loud, irregular snoring
  • Breathing pauses during sleep
  • night sweats
  • no restful sleep
  • Daytime sleepiness
  • Headaches
  • easily irritated
  • Despite taking beta-blockers, his blood pressure remained consistently too high

Unfortunately, no doctor has been able to determine the cause of these symptoms.

I visited a pulmonologist to get a diving certificate (diving is my hobby). After measuring my lung capacity and oxygen saturation, he prescribed continuous positive airway pressure (CPAP) therapy.

Everything was fine at first, until, after six months, I developed a severe allergy to the breathing mask (I had tried different masks). The CPAP method was no longer an option for me.

I looked for alternative methods and discovered the mandibular advancement splint. My snoring has stopped, which is great.

It was only in the sleep lab that it was determined that the airways remained just as narrow (oxygen saturation was equally poor with and without the mandibular advancement splint).

What a stroke of luck! I heard about Professor Sailer. I made an appointment right away.

At first, I was still skeptical because of everything that lay ahead of me….
But after just the first consultation, it was clear to me:
Professor Sailer can heal. The decision was made quickly:
Yes, surgery is my salvation: A few more appointments followed before the surgery date was set.
My sleep apnea surgery was scheduled for January 23, 2019, at 7:30 a.m.
I was already lying in the prep room wearing my surgical gown and was ready. Then Professor Sailer came in, took his time, and spoke very reassuringly about how he was going to operate on me shortly. I don’t remember the details, but I’ll never forget his incomparably reassuring and empathetic manner. For that, I am still infinitely grateful to Professor Sailer.

Nine months have passed since Professor Sailer operated on me.
I feel great! All the wounds have healed, and there have been no complications since then.

My quality of life has improved tremendously:

Here are the changes I’ve noticed in myself:

  • Immediately after the surgery, the episodes stopped completely.
  • I sleep soundly through the night because I no longer have breathing pauses at night
  • My sleep periods have increased from 4 to 6 hours to 7 to 8 hours
  • My blood pressure has returned to normal; it used to be 190/100, but now it’s 125/75 (I’m no longer taking a beta-blocker)
  • No fatigue or drowsiness during the day
  • no headaches
  • Before the surgery, my heart rate would go up to 150 beats per minute during strength training; now it reaches a maximum of 112.
  • Climbing stairs is no longer a problem: I can go up seven flights, and I’m still breathing normally—whereas before, I used to have to take forced breaks along the way.
  • Nothing can rattle me anymore.

Many thanks to Professor Sailer and his excellent team for the brilliant surgery and the compassionate, professional care before, during, and after the procedure.
It was also very reassuring to know that I could reach out at any time.

I’m healed. It’s wonderful!

Longevity – Medicine for a Longer, Healthier Life

Prof. Dr. Dr. Hermann F. Sailer devoted himself not only to curing acute diseases and reconstructing the face but also to exploring how people can preserve their health, vitality, and quality of life into advanced age. Under the guiding principle of “Longevity Medicine,” he developed concepts that combine cutting-edge research with preventive and regenerative medicine.

His approach goes beyond classical surgery: through precise diagnostics, metabolic analyses, nutritional medicine, as well as innovative cell and tissue therapies, the biological foundations of aging are specifically addressed. The goal is to slow down the aging process, prevent disease, and strengthen the body’s regenerative capacities. Prof. Sailer’s concept of increasing oxygen intake by expanding the upper airways has been scientifically proven to rejuvenate prematurely aged organs.

In doing so, Sailer created a treatment model aimed not merely at a longer life, but at a longer healthy life – characterized by vitality, mental clarity, and a youthful appearance. His work in longevity unites medical prevention, aesthetic considerations, and holistic quality of life into a forward-looking model of modern medicine.
