儿童鼻咽侧位平片的临床意义(附126例X线分析)

The clinical value in children of nasopharyngeal lateral plain film

目的:通过测定腺样体———鼻咽腔比率(A/n比值)来评定腺样体肥大的标准。方法:随机选择126例就诊患儿,均常规摄吸气期鼻咽侧位片。结果:A/n比率≤0.70的患儿经保守治疗后症状可显著改善,而A/n比率≥0.71的患儿中大部分需行腺样体刮除术。结论:摄吸气时的鼻咽侧位片是诊断腺样体肥大的实用而准确的方法,当A/n比率≥0.71时为腺样体病理性肥大。

Objective To evaluate the clinical usefulness of adenoidal hypertrophy on measuring adenoid-nasopharynx ratio (A/n ratio). Method 126 clinical case were selected, nasopharyngeal lateral film with inspiration were taken to measure the A/n ratio. Results The symptoms of all patients with A/n ratio ≤0.70 improved distinctly after conservative treatment, but more one half of patients with A/n ratio ≥0.71 required adenoidectomy. Conclusion Nasopharyngeal lateral film with inspiration is a practical and correct examination for visualizing adenoid hypertrophy. A/n ratio ≥0.71 indicates pathological enlarged adenoid.
