To determine success rates after adenotonsillectomy for obstructive sleep apnea (OSA); postoperative polysomnogram (PSG) results were compared with preoperative results in children younger than 5 years.
Thirty-four children with a preoperative respiratory disturbance index (RDI) greater than 5 in rapid eye movement (REM) sleep underwent both preoperative and postoperative PSG with at least five of seven parameters recorded.
Preoperatively, mean total RDI was 15.5, mean REM RDI was 39.6, and 25 (74%) had severe OSA (REM RDI > 20). Postoperatively, mean total RDI improved to 3 (P < 0.001), mean REM RDI to 7.4 (P < 0.001), and 4 remained severe. Overall 22 (65%) showed REM RDI in the normal range (<5), including all with a preoperative REM RDI less than 30.
On PSG criteria, most children with OSA significantly improved after adenotonsillectomy, but a number had persisting abnormalities. Postoperative PSG should be considered to identify unresolved OSA.
确定腺样体扁桃体切除术后治疗阻塞性睡眠呼吸暂停（OSA）的成功率；将5岁以下儿童术后多导睡眠图（PSG）结果与术前结果进行比较。
34例术前快速眼动（REM）睡眠期呼吸紊乱指数（RDI）大于5的儿童接受了术前和术后PSG检查，记录了七个参数中的至少五个。
术前，平均总RDI为15.5，平均REM RDI为39.6，25例（74%）患有重度OSA（REM RDI>20）。术后，平均总RDI改善至3（P<0.001），平均REM RDI改善至7.4（P<0.001），4例仍为重度。总体而言，22例（65%）的REM RDI在正常范围内（<5），包括所有术前REM RDI小于30的儿童。
根据PSG标准，大多数OSA儿童在腺样体扁桃体切除术后有显著改善，但仍有一些儿童存在持续异常。应考虑进行术后PSG检查以识别未解决的OSA。
