Laser palatoplasty (LPP) is widely used for the treatment of non-apnoeic snoring, despite the lack of objective data supporting its use. We report measurements of snoring in a prospective study of LPP, and we compare the results with a previous study of uvulopalatopharyngoplasty (UPPP). Twenty patients with an apnoea/hypopnoea index <20 h(-1) underwent LPP for habitual snoring. Overnight sound recordings were compared before and 6 months after operation using three objective indices; L-1 (the level exceeded by the loudest 1% of sound), L-5 (the level exceeded by the loudest 5% of sound) and P-50 (% total sleep time above 50 dBA). The subjective impression of snoring severity (Wilcoxon test, P < 0.001), and objective indices L-1 and P-50 (t-test, P < 0.001) showed significant reductions after LPP. The mean change in L-1 was 4.2 dBA, comparable to that we previously reported for UPPP, while P-50 was reduced to less than one-third its preoperative value. No other sleep variables changed significantly following LPP. We conclude that LPP results in reduced snoring volume comparable to that following UPPP.
