Lost Voices: A Survey of Knowledge of Temporal Mandibular Joint Disorder and Muscle Tension Dysphonia in the Professional Voice Studio

Temporal Mandibular Joint Disorder (TMD) and Muscle Tension Dysphonia (MTD) are presently two of the most common vocal disorders in the world. These disorders can wreak havoc in anyone’s life; but are incredibly destructive in the lives of singers. When a classically-trained singer begins to notice problems in his or her voice, they typically go to their favored Professional Voice Instructor (PVI) for help. However, not all PVIs are familiar with these disorders and their symptoms, and what starts as a sincere wish to help their student can end with injury instead. This study surveys PVIs to determine what they know and do not know about TMD and MTD and if they have worked with medical professionals -- otolaryngologists and Speech Language Pathologists (SLP) - to assist their students. The study poses the questions of how prevalent the knowledge and treatments of TMD and MTD are with PVIs and how open PVIs are to ongoing education about these disorders. Included in this document is a brief summary of each disorder with illustrations as well as opinions from a Speech Language Pathologist.
