Abstract

PURPOSE: To evaluate the relationship between facial cephalometric measures and response to uvulopalatopharyngoplasty (UPPP).

PATIENTS AND METHODS: Retrospective analysis of skeletal cephalometric measures obtained from a consecutive sample of 43 patients with obstructive sleep apnea syndrome (OSAS) who underwent body mass index (BMI) measures, UPPP, upright lateral cephalometric radiographs, and preoperative and postoperative polysomnography. Significant clinical effect by uvulopalatopharyngoplasty was arbitrarily defined as having a 50% reduction in the respiratory disturbance index (RDI). The cephalometric measurements used were based solely on skeletal landmarks.

RESULTS: No skeletal measurement predicted response to UPPP for the entire study population. When the patients were classified on the basis of retrognathia, 33 were identified without retrognathia. In that group, posterior airway length was the greatest predictor of response to UPPP (P < or = .05; odds ratio, 83.2). The distance between hyoid and mandible and the maxillary-mandibular relationship were also predictive of response (P < or = .05).

CONCLUSION: The skeletal anatomy supporting the airway directly impacts the response to UPPP. Prediction of response requires stratification by skeletal subtype.
