数字化X线摄影对儿童腺样体肥大的诊断价值分析

Application of Digital Radiography on Pediatric Adenoidal Hypertrophy

目的:探讨鼻咽部侧位片对小儿腺样体肥大的诊断价值。方法:43例怀疑腺样体肥大患儿均摄鼻咽部侧位片,测量腺样体厚度、鼻咽腔宽度及后气道宽度(PAS),并计算腺样体指数A/N,以评估腺样体肥大程度。结果:A/N≤0.60者8例,0.61～0.70者7例,A/N≥0.71者28例;PAS≤5mm者18例;6～10mm者12例;≥10mm者13例。结论:X线鼻咽侧位片是诊断腺样体肥大简单、经济的一种重要检查方法。

Objective：To discuss the diagnostic value of nasopharyngeal lateral film for pediatric adenoid hypertrophy.Methods：43 suspected cases with adenoid hypertrophy had nasopharyngeal lateral films taken.The thickness of adenoid,the widths of nasopharyngeal cavity were measured to calculated the adenoid-nasopharynx ratio （A/N）.The degree of adenoid hypertrophy was assessed by the A/N and the pharyngeal airway space （PAS）.Results：The ratios of A/N were found less than 0.60 in 8 cases,0.61-0.70 in 7 cases and more than 0.71 in 28 cases.The values of PAS were less than 5mm in 18 cases,6-10mm in 12 cases and more than 10mm in 13 case.Conelusion：Nasopharyngeal lateral film is a simple and correct examination for visualizing adenoid hypertrophy.
