Orthognathic Speech Pathology: Phonetic Contrasts of Patients With Dental Discrepancies Pre- and Post-Treatment Analyses
Orthognathic Speech Pathology: Phonetic Contrasts of Patients With Dentofacial Discrepancies With Pre- and Post-Treatment Analyses
University of North Carolina, Chapel Hill
180 participants
Sep 11, 2019
OBSERVATIONAL
Conditions
Summary
The investigators are studying how speech is effected by jaw and tooth position in jaw surgery patients. Eighty percent of our jaw surgery patients have speech pathologies, compared to five percent of the general population, but speech pathologists do not understand why. The investigators hypothesize that open bites and underbites prevent most patients from being able to pronounce words normally and surgical correction will lead to improvement in speech. Patients will be audio recorded speaking and patients' tongue gestures ultrasound recorded before and after their jaw surgeries to observe what changes occur in their speech and tongue movements.
