Prof. Dr. Hasan Demirhan is a double board-certified otolaryngologist and Professor of Otolaryngology practising in Bahçelievler, Istanbul, with a clinical focus on functional and aesthetic rhinoplasty. He has performed over 4,000 procedures and treats patients travelling from across Europe, the Middle East and beyond.
He graduated from Ankara University Faculty of Medicine in 2003 and completed his specialist training in Otorhinolaryngology and Head & Neck Surgery at Haseki Training and Research Hospital in Istanbul, qualifying as a specialist in 2009. He went on to earn the title of Professor, and has trained internationally in advanced rhinoplasty technique.
His approach rests on a single principle: the nose is a functional organ and a defining facial feature at the same time, and it should not be treated as one or the other. Patients are too often asked to choose between breathing well and looking well. Prof. Dr. Demirhan plans every case around both — assessing the internal nasal airway alongside facial proportion, skin thickness and the patient's own aesthetic goals before proposing a surgical plan.
In rhinoplasty, he performs primary aesthetic nose surgery, scarless (closed) rhinoplasty leaving no external incision, and revision rhinoplasty for patients dissatisfied with or experiencing complications from previous surgery elsewhere. Revision cases form a significant part of his practice, and are approached conservatively, with realistic discussion of what a second operation can and cannot correct.
On the functional side he performs septoplasty and nasal obstruction surgery, endoscopic sinus surgery, and combined septorhinoplasty where breathing and appearance are addressed in a single operation — sparing the patient a second anaesthetic and a second recovery.
His facial aesthetic work covers temporal lift, lip lift, chin aesthetics, bichectomy and otoplasty (prominent ear correction), each planned to sit in proportion with the rest of the face rather than as an isolated change. Non-surgical treatments including anti-wrinkle injections and dermal fillers are offered where a surgical procedure is not warranted, and he will say so directly when that is the case.
As a fully trained ENT specialist he also treats conditions outside facial aesthetics entirely: endoscopic ear surgery, cochlear implant surgery, and the diagnosis and management of vertigo and balance disorders. This depth in general otolaryngology is what underpins his functional nasal work and distinguishes his practice from purely cosmetic facial surgery.
Every patient begins with a detailed consultation in which facial anatomy is assessed, expectations are discussed openly, and the range of possible outcomes — including limitations — is explained before any commitment is made. Recovery is monitored closely, with the clinic maintaining direct and open communication throughout the post-operative period. Patients consistently describe minimal pain and bruising, and a process in which they felt informed and secure at every stage.
The clinic is located in Yenibosna, Bahçelievler, on Istanbul's European side, in a modern facility designed for patient comfort and privacy. The practice is experienced in caring for international patients and coordinates consultation, surgery and follow-up around travel schedules. Prof. Dr. Demirhan holds a 4.9-star patient rating on Google.
Natural, harmonious results are the goal throughout — refined enough to enhance confidence, subtle enough that a procedure is not the first thing anyone notices.
