摘要
目的：采用鼻咽侧位平片测定儿童增殖腺－鼻咽腔比率（Ａ／Ｎ比率）来判断儿童的增殖腺属正常抑或病理性肥大。材料与方法：随机选择１０６例门诊诊断为分泌性中耳炎的患儿，在治疗前作Ａ／Ｎ比率测定。结果：Ａ／Ｎ比率在０．５０～０．７０内，经保守治疗后症状可显著改善，而Ａ／Ｎ比率≥０．７１的患儿中有半数需行增殖腺刮除术。结论：Ａ／Ｎ比率是一种实用、方便的增殖腺Ｘ线测定方法。当Ａ／Ｎ比率≥０．７１时为增殖腺病理性肥大。
Purpose: To evaluate the clinical usefulness of adenoid nasopharynx ratio (A/N ratio) measured on nasopharyngeal lateral plain film. Materials and methods: 106 clinical cases of secretory otitis media were selected to measure the A/N ratio before treatment. Results: For patients with A/N ratio of 0.50 0.70, the symptoms improved distinctly after conservative treatment, but one half of patients with A/N ratio ≥0.71 required adenoidectomy. Conclusion: A/N ratio is a practical and convenient method for evaluation of the adenoid. A/N ratio≥0.71 indicates pathological enlarged adenoid.
