射频低温等离子消融术治疗阻塞性呼吸暂停低通气综合征116例

目的 探讨用射频低温等离子消融术(RFA)治疗轻-中度阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的临床疗效.方法 对116例OSAHS患者按阻塞平面采用RFA单独或同时对口咽、软腭部、下咽舌根部治疗.治疗前做PSG检查,测定口咽腔解剖径线,包括:悬雍垂基部至舌背距离、腭舌弓间距、腭咽弓间距.治疗后随访12个月,做PSG检查评价疗效,测定口咽解剖径线与术前进行比较.结果 116例轻-中度0SAHS患者:治愈53例,有效45例,无效18例,总有效率84.4%(98/116).与治疗前比较,呼吸暂停低通气指数(AHI)明显降低(P＜0.01)最低血氧饱和度(LSaO2)增高(P＜0.01),悬腭垂基部至舌背距离、腭咽弓和腭舌弓间距均增宽(P＜0.01).结论 射频低温等离子消融术治疗作用范围准确,减容效果确切,对组织损伤小,操作简便,是一种治疗轻-中度OSAHS的有效方法.

Radiofrequency Ablation for Obstructive Sleep Apnea-hypopnea Syndrome: a Review of 116 Cases

Objective To investigate the curative effect of radiofrequency ablation (RFA) on light and medium obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods116 cases of OSAHS were treated with RFA on soft palate alone or soft palate and tongue base together. The follow up period was 12 months. Polysomnography (PSG) was taken and the following indexs was measured before and after RFA: distance between uvula and tongue (DBUT),distance between anterior pillars (DBAP) , distance between posterior pillars (DBPP).Results It was found that 53 cases had effects, 18 cases had no effects. The total ratio of validity was 84.4%. The postoperative AHI, minimal SaO 2, DBUT, DBAP, DBPP has significant difference compared with that of preoperative indexs. Conclu- sions RFA is a safe and effective method for light and medium OSAHS.
