Analyzing speech changes in jaw surgery patients
Orthognathic Speech Pathology: Phonetic Contrasts of Patients With Dentofacial Discrepancies With Pre- and Post-Treatment Analyses
University of North Carolina, Chapel Hill · NCT04117360
This study looks at how jaw surgery affects the way people speak by recording their speech and tongue movements before and after the surgery.

What this trial studies
This observational study investigates how jaw and tooth positions affect speech in patients undergoing orthognathic surgery for dentofacial abnormalities. Researchers will record patients' speech and tongue movements before and after surgery to assess changes in phoneme distortion and tongue posture. The study aims to quantify the prevalence of speech distortions and evaluate the impact of surgical correction on speech quality. By using advanced analysis techniques, the study seeks to provide insights into the relationship between jaw alignment and speech pathology.
Who should consider this trial
Good fit: Ideal candidates are patients aged 15-40 with skeletal open bites, underbites, or overjets greater than 5mm who are seeking orthognathic surgery.
Not a fit: Patients with hearing loss, significant regional accents, or a history of craniofacial disorders may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved speech outcomes for patients with dentofacial discrepancies following surgical treatment.
How similar studies have performed: While there is limited research specifically on this approach, studies have shown that surgical correction can improve speech in patients with dentofacial abnormalities, suggesting potential for success.
