Mother Nature's main rule, ‘Form follows function,’ is the central theme of voice therapy. Applied biomechanics underlies the outcomes of behavioral treatment for voice disorders.
Voice habilitation and rehabilitation require a multidimensional approach. Voice therapy, including habilitation and rehabilitation, requires more than applying a specific therapeutic technique; it involves integrating scientific evidence, clinical expertise, and each patient's individual needs. Successful voice (re)habilitation depends on appropriate patient selection, understanding the underlying phonatory mechanism, and tailoring therapeutic strategies to individual responses and functional voice demands.
In this sense, voice disorders must not be regarded solely as local laryngeal problems. However, vocal fold function and healing are influenced by a complex interaction of genetic susceptibility, inflammation, allergy, reflux, sleep, stress, nutrition, environmental exposures, tissue repair mechanisms, and cellular mechanotransduction.
Professional voice users require particular attention. Occupational voice (re)habilitation can be viewed as a progression from sensory-motor recalibration and efficient phonation to vocal conditioning, job-specific transfer, and self-management. This provides not only habilitative outcomes but also self-controlled sustainability for voice-demanding occupations.
In this panel, we will also discuss various voice therapy methods for practical clinical application.
Assoc. Prof. Dr. İlter Denizoglu, MD1, PhD2, MSc3
1Otorhinolaryngology, 2 Biophysics, 3 Audiology & Speech Pathology
Vocology Centre (Founder & Director)
University Lecturer of Clinical Vocology in Tinaztepe University Faculty of Health Sciences, Speech Language Therapy Division
University Lecturer of Pedagogical Vocology in Dokuz Eylül University State Conservatory Vocal Arts Department, Main Art Division of Opera
After studying medicine at Ege University Faculty of Medicine and completing otolaryngology-head and neck surgery training at the Otolaryngology Department of Dokuz Eylul University Faculty of Medicine, Dr. Denizoglu decided to pursue a career in phoniatrics. His interest began with the fundamental physics of voice; he then studied vocal pedagogy at the conservatory of music. He completed a PhD in Biophysics and an MSc in Audiology & Speech Pathology. 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.
He is an amateur singer with an interest in vocal music from multiple perspectives, including singing pedagogy and musical acoustics. He has prepared the curriculum for Pedagogical Vocology lessons and has been delivering lectures at Dokuz Eylul University's Faculty of Stage Arts, Opera Division, since 2009. He has also developed the Clinical Vocology curriculum and teaches in the Speech-Language Therapy Division of the Faculty of Health Sciences at Tınaztepe University in Izmir, as well as in the Phoniatrics master's training program at Lokman Hekim University, Department of Otorhinolaryngology, Ankara. He gives invited lectures at training programs and congresses worldwide. He has conducted his certifying training programs in pedagogical and clinical vocology (2-4 days) in more than 20 countries.
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.
