Assoc. Prof. Dr. Necati Enver is an Otolaryngologist (ENT) specialist who has dedicated his career to the research and treatment of voice, swallowing, and airway disorders. With his expertise in non-surgical treatment approaches and his internationally diverse training background, he has become one of Turkey's leading figures in the field of laryngology.

Dr. Enver began his medical education at Hacettepe University Faculty of Medicine, one of Turkey's most prestigious medical schools, and completed his residency training in Otolaryngology–Head and Neck Surgery at Istanbul University ENT Clinic. During his residency, he had the opportunity to expand his knowledge and experience on an international level, training at the renowned Università Degli Studi Di Genova in Italy — an experience that gave him close exposure to different clinical approaches practiced across Europe. During this same period, he also participated in research at the Cancer Stem Cell Laboratory of Charité University Berlin, a leading institution in head and neck cancer research, further strengthening his scientific background in oncology.

Determined to continue his academic and clinical development at an international level, Dr. Enver moved to the United States, where he worked at the Voice Center of the University of Pittsburgh Medical Center (UPMC), gaining advanced knowledge and experience in voice, speech, and swallowing disorders. During this time, he successfully completed all four steps of the USMLE examinations required for U.S. medical licensure equivalency. Following this achievement, he was accepted into the joint Laryngology Fellowship Program of Weill Cornell Medicine and Columbia University in New York — two internationally renowned institutions. Throughout this prestigious one-year fellowship, Dr. Enver received intensive, hands-on surgical and clinical training, achieving a world-class level of expertise in laryngology. This experience allowed him to refine both his surgical skills and his clinical judgment in approaching voice and swallowing disorders at the highest level.

After completing this extensive period of training abroad, Dr. Enver returned to Turkey and continued his academic career as a faculty member at Marmara University ENT Clinic. As a result of his scientific work, publications, and teaching activities, he was awarded the title of Associate Professor in 2021. Continuing his academic, educational, and clinical responsibilities at one of the leading universities on Istanbul's Anatolian side, Dr. Enver has also contributed significantly to the training of young physicians.

Today, Assoc. Prof. Dr. Necati Enver practices at his own clinic while also serving as a Board Member of the European Laryngological Society (ELS), playing an active role in the international scientific community. He has made it his principle to offer patients minimally invasive, non-surgical treatment options whenever possible for a wide range of ENT conditions, particularly hoarseness, swallowing difficulties, and vocal cord disorders. Closely following the latest global advancements in his area of passion — voice and swallowing disorders — Dr. Enver continues to apply this accumulated knowledge both in patient care and in the innovative educational approaches he shares with his students.

Prof. Dr. İsmail Koçak, MD, MSc (Biomedical Engineering) is an otolaryngologist–head & neck surgeon with a clinical and academic focus on laryngology, phonosurgery, and professional voice care, integrating surgical innovation with voice science. He has been working in the field of voice since 1993, with a particular interest in tissue-preserving microlaryngeal surgery, esthetic/identity-related voice surgery, and objective outcome assessment.

He received his MD from Hacettepe University Faculty of Medicine (1992), completed ENT residency at Ankara University (1996), and earned an MSc in Biomedical Engineering from Boğaziçi University (2002) with a thesis on laryngeal resonance modeling and surgical optimization of voice quality. His specialty thesis addressed implant design for unilateral vocal fold paralysis. He was appointed Associate Professor (2010) and later Professor and Department Chair (2016–2019).

Prof. Koçak has contributed to the development and clinical dissemination of several techniques in esthetic voice surgery and phonosurgery, including approaches for pitch and timbre modulation and tissue-preservation strategies in microlaryngeal interventions. His clinical practice encompasses voice feminization/masculinization, pitch-range modulation, thyroplasty, complex revision voice cases, and management of organic laryngeal pathology, including laryngeal masses and oncology-related voice rehabilitation, as well as treatment of spasmodic dysphonia.

His research output includes publications in international peer-reviewed journals, notably on novel surgical techniques and imaging/diagnostic features in phonosurgery (e.g., Journal of Voice), and interdisciplinary work bridging signal processing, imaging, and machine learning with laryngology. He has supervised doctoral research in voice therapy and vocal training and led funded academic work including the “Acoustic Body Project” (TÜBİTAK, 2015–2018).

He is a frequent invited speaker and panelist at major international meetings, including the American Academy of Otolaryngology–Head and Neck Surgery (international sessions on challenging laryngology cases and esthetic voice surgery) and European laryngology platforms. He is a member of professional societies including the European Laryngological Society and the Acoustical Society of America. Prof. Koçak is based in Istanbul, where he practices and teaches in the field of voice surgery and vocology.
