目的 探讨小儿OSAHS腺样体手 术前后的X线对照评价，为临床手术疗 效评估提供参考依据。方法 确诊儿童 OSAHS、均行腺样体切除手术患者11例， 分别于术前和术后进行X线摄片，将手术 前后数据比较、统计学处理。结果 患 儿手术前后X线测量结果运用配对检验 比较，顶后壁软组织(即腺样体)厚度(A 值)、A/N两组数据P＜0.05，两者差异有 统计学意义。结论 X线测量A值、A/N值 可以作为评价手术前后疗效重要参考。

Objective To explore Obstructive sleep apnea-hypopnea syndrome (OSAHS) in children variation perioperatively based on X-ray. Methods X-ray manifestations of eleven OSAHS in children with adenoidhypertrophy were retrospectively analyzed in my hospital (2009.1-2015.2). To observe and measure upper airway and adenoid, and compare numerical data perioperatively. Results All data have significant difference compare preoperative and postoperative by paring t test: A(thickness of adenoid), A/N(P <0.05). Conclusion Numerical data of X-ray (as A, A/N) could do objective evaluation of OSAHS in children of adenoidectomy perioperatively, and be collated for clinical application.
