Long-Term Surgical and Speech Outcomes Following Palatoplasty in Patients With Treacher-Collins Syndrome.

Background: Cleft palate is present in one-third of patients with Treacher-Collins syndrome. The authors present long-term speech and surgical outcomes of palatoplasty in this challenging patient population.

Methods: A retrospective review of all patients with Treacher-Collins syndrome and cleft palate was conducted over a 35-year period at a single institution.

Malocclusion and its relationship to speech sound production: Redefining the effect of malocclusal traits on sound production.

Introduction: The purpose of this study was to identify variables of dental malocclusion with the greatest effect on sound production that can be easily identified during an orthodontic assessment.

Methods: One hundred fifteen patients (8.2-36 years of age) seeking orthodontic evaluation were assessed for speech sound production abnormalities.

Effects of fixed labial orthodontic appliances on speech sound production.

Objective: To explore the impact of fixed labial orthodontic appliances on speech sound production.

Materials And Methods: Speech evaluations were performed on 23 patients with fixed labial appliances. Evaluations were performed immediately prior to appliance insertion, immediately following insertion, and 1 and 2 months post insertion.
