    Abstract:
    The objective of this study was to assess the value of preoperative fiberoptic nasopharyngoscopy with the Müller maneuver (FNMM) and cephalometric radiography in predicting response to uvulopalatopharyngoplasty (UPPP) in patients with obstructive sleep apnea syndrome. Fifty-three such patients having significant obstruction at the soft palatal level and variable degrees of obstruction at the base-of-tongue level underwent both diagnostic procedures before UPPP. Outcome was assessed by the apnea-plus-hypopnea index (AHI) as determined by polysomnography, which was performed before and after surgery. As a group, patients exhibited a significant 10-point reduction in AHI (46.5 to 36.7). However, 17 (32.1%) were judged to be responders as defined by a reduction of the AHI by an increment of 50% or greater with respect to baseline. Of all the cephalometric variables assessed, soft palate length was the only one that differed between responders and nonresponders (45.5 mm versus 42.6 mm, respectively). However, this difference only approached significance (P = .067). Similarly, FNMM results did not discriminate between responders and nonresponders. These results indicate that preoperative cephalometric radiography and FNMM cannot be reliably used to enhance surgical success.
