Since 1999, my medical and surgical practice has been limited to voice care. I maintain an

informational web site on voice disorders - voicedoctor.net, preceptor medical students in their

early years at Oregon Health Sciences University, offer an international fellowship in laryngology as

well as short observerships to physicians, speech therapists, voice teachers and interested students.

I produce “voxdoc, the voicedoctor” on YouTube, including Laryngology 101, a series of learning

videos. I published “Why is there a frog in my throat? A guide to hoarseness.” I frequently lecture

internationally on laryngology and phonosurgery. I remain surprised at how much there is still to learn

about the larynx.

He has participated in several ongoing and published clinical studies and laboratory research. His passion for gaining a comprehensive understanding of the human voice across basic, clinical, and pedagogical vocology continues.

Dr. Denizoglu actively participates in several associations in the field of human voice, including the Union of European Phoniatricians (UEP), Collegium Medicorum Theatri (CoMeT), and the International Association of Logopedics and Phoniatrics (IALP). In addition to his invited lectures worldwide, he conducts training workshops in various countries on voice therapy, singing voice therapy, and phonosurgery.

His medical practice focuses exclusively on phonosurgery, voice therapy, and singing voice therapy. He has developed new devices for voice therapy and vocal training. Based on Sihvo’s LaxVox Tube Exercise, he developed the DoctorVox Voice Therapy and Vocal Training Method (DVT) and holds patents for the tools used in DoctorVox therapy. He has also developed techniques such as mini-microsuture and posterior glottoplasty, as well as surgical instruments for phonosurgery. His book, 'Textbook of Clinical Vocology,' was published in 2020.
