Radiofrequency volumetric reduction of the palate: An extended follow-up study OTOLARYNGOLOGY-HEAD AND NECK SURGERY Li, K. K., Powell, N. B., Riley, R. W., Troell, R. J., Guilleminault, C. 2000; 122 (3): 410-414


The goal was to evaluate the effect of radiofrequency (RF) of the palate on speech, swallowing, taste, sleep, and snoring 12 to 18 months after treatment.Twenty-two patients were evaluated by clinical examination, questionnaires, and visual analog scales. The patients with relapse of snoring were offered further RF treatment.After a mean follow-up of 14 months, no adverse effect was reported. Subjective snoring scores relapsed by 29% overall. Nine patients (41%) noted relapse of snoring from 2.1 +/- 1. 1 to 5.7 +/- 2.7 (P < 0.001). Eight of the patients underwent further RF treatment with a reduction of snoring from 5.8 +/- 2.9 to 3.3 +/- 3.1 (P = 0.01).The success of RF volumetric reduction of the palate diminishes with time, as with other surgical procedures of the palate. However, the minimal invasiveness of the RF provided a high patient acceptance for retreatment, and relapse of snoring can be improved.
