为了解小儿阻塞性增殖体肥大(OAH)的发病机理和继发病变,对94例正常或病变的增殖体、硬腭、软腭、口咽和鼻咽解剖关系进行测量。本组依增殖体有无病变分为:A正常组19,B阻塞性肥大组44,C慢性感染组13。测量项目有:①扁桃体、咽前柱和咽侧壁间距;②软腭长,硬腭长、宽和拱高;③鼻咽深度;④增殖体切除术前和术后鼻咽部容积;⑤ In order to understand the pathogenesis and secondary lesion of pediatric obstructive proliferative hypertrophy (OAH), 94 normal or diseased proliferators, hard palate, soft palate, oropharynx and nasopharyngeal anatomy were measured. The group according to the presence or absence of proliferative lesions were divided into: A normal group 19, B obstructive hypertrophy group 44, C chronic infection group 13. Measurement items are: ① tonsil, pharyngeal column and pharyngeal side wall spacing; ② soft palate length, hard palate length, width and arch height; ③ nasopharyngeal depth; ④ pre-and post-proliferative nasopharyngeal volume; ⑤
