摘要
目的利用鼻咽侧位片测量儿童腺样体—鼻咽腔比率(A/N比率)来判定儿童腺样体肥大的标准。方法随机选择有打鼾、鼻塞、张口呼吸及分泌性中耳炎患儿140例,于治疗前行A/N比率测定。结果A/N比率≤0.70的患儿经保守治疗症状显著改善,而A/N比率≥0.71的患儿大部分需行腺样体刮除术。结论摄鼻咽侧位片测定A/N比率是诊断腺样体肥大的简便实用且准确的检查方法。A/N比率≤0.60属正常,0.61～0.70为中度肥大,≥0.71为病理性肥大。
[Objective] To evaluate the clinical usefulness of adenoidal hypertrophy on measuring adenoid-nasopharynx ratio（A/N ratio） of nasophyryngeal lateral plain film. [Methods] 140 clinical cases including snorers, opening mouth＇s respiration,secretory tympanitis were selected to measure the A/N ratio before treatment. [Results] Patients＇ symptoms, whose A/N ratio ≤0.70, were improved distinctly after conservative treatment, but most of patients with A/N ratio ≥ 0.71 required adenoidectomy. [Conclusion] The A/N ratio of nasopharyngeal lateral plain ftlm is a convenient, practical and correct examination for adenoid hypertrophy. The A/N ratio ≤0.60 is considered normal, from 0.60 to 0.70 belongs to mid-grade hypertrophy, and ≥0.71 suggests of pathological hypertrophy.
