摘　　要：目的:探讨X线鼻咽侧位平片表现及评价测量腺样体/鼻咽腔(A/N)比值的临床应用价值。材料与方法:病变组213例中,男134例,女79例;正常组46例中,男22例,女24例。均常规摄吸气期鼻咽侧位平片和测量A/N比值。结果:(1)病变组:鼻咽顶后壁软组织增厚,鼻咽腔变窄;全部213例A/N比值≥0.61,101例A/N≥0.71。(2)正常组:A/N比值均<0.6为正常,鼻咽顶后壁软组织边缘不凸出或轻微凸出。结论:(1)摄吸气时的鼻咽侧位片是观察腺样体肥大的简单而准确的方法;(2)测量A/N比值用以观察腺样体肥大的程度,A/N≤0.60为正常,≥0.61为腺样体肥大,≥0.71者为腺样体显著肥大。(3)测量A/N对选择腺样体刮除术具有一定的临床价值。Purpose： To discuss the X- ray manifestations of adenoidal hypertrophy on plain film in children and to evaluate the clinical application value of A/N. Materials and Methods： One hundred and thirty-four men and 79 women were diagnosed with adenoidal hyper- trophy. Forty-six cases were collected as normal control group. Nasopharngeal lateral films were taken for both study group and control group, the A/N ratio was measured. Results： （1） In study group： file soft tissues in nasopharyngeal roof and posterior part were thickened, the nasopharyngeal cavity were narrowed, all their A/N ratios were 90.61, and 101 cases of them were 90.71. （2） The A/N ratio in normal group were ≤0.61. The margin of soft tissues in nasopharyngeal roof and posterior part didn＇t protrude or protrude slightly. Conchusion： （ 1 ） Nasopharyngea lateral fihn with inspiration is a sinlple and correct examination for observing adenoidal hypertrophy. （2） Measuring of A/N ratio is used for observing the degree of adenoidal hypertrophy, the normal A/N ratio ≤0,60, ≥0.61 indicates adenoid hypertroophy, and ≥0.71 indicates marked adenoid hypertrophy. （3） Measuring of A/N ratio has significant clinical value in selectiong of curettage of adenioids.
