Abstract
Laser‐assisted uvulopalatoplasty (LAUP) is a procedure for the treatment of snoring and, possibly, sleep apnea. Between July 1993 and December 1994, the authors prospectively evaluated 541 consecutive patients referred to their teaching hospital for possible LAUP to treat loud, disruptive snoring. Of these patients, 274 (51%) had one or more LAUP treatments. As of January 1995, LAUP treatment courses were completed in 170 patients. In this paper, the authors report preliminary results on the use of LAUP in these patients.Among the 170 patients, 105 (62%) had a diagnosis of snoring and 65 (38%) obstructive sleep apnea syndrome (OSAS) based on preoperative polysomnography. LAUP treatment in the snoring only patients resulted in complete or nearly complete elimination of snoring in 63 patients (60%), partial improvement of snoring in 30 patients (29%), and no improvement in 11 patients (10%). Of the 65 OSAS patients treated with LAUP, postoperative polysomnograms were obtained in 33 patients (51%). Surgical success was achieved in 16 (48%) of the 33 patients. However, 7 patients (21%) had repeat polysomnograms that were worse than their preoperative polysomnograms, and 5 patients (15%) had no significant change. The results of this study suggest that LAUP may be a viable surgical option for patients with snoring and mild sleep apnea.
