Nasopharyngeal airway obstruction by adenoidal tissue was studied in children with otitis media with effusion compared with children with healthy ears. Adenoidal and nasopharyngeal development with age also were studied.
The study included 44 children with bilateral effusive otitis media and 32 children without ear disease, all of whom were scheduled for adenoidectomy. In a preoperative lateral radiograph of the nasopharyngeal cavity, adenoidal tissue and the nasopharynx were measured. Adenoidal volume and weight were measured after surgery.
The group with effusive otitis media had a larger adenoidal volume, smaller nasopharyngeal cavity, and greater nasopharyngeal airway obstruction (all significant differences) than children without ear disease. All the children had an increase in the nasopharyngeal cavity with age and a decrease in adenoidal volume and nasopharyngeal obstruction after the age of seven years.
对患有中耳积液的儿童与耳部健康的儿童进行比较，研究腺样体组织导致的鼻咽气道阻塞情况。同时也研究了腺样体及鼻咽随年龄的发育情况。
该研究纳入了44例双侧渗出性中耳炎患儿和32例无耳部疾病的患儿，所有患儿均计划接受腺样体切除术。在术前鼻咽腔侧位X线片中，测量腺样体组织和鼻咽部。术后测量腺样体体积和重量。
与无耳部疾病的儿童相比，中耳积液组的腺样体体积更大、鼻咽腔更小且鼻咽气道阻塞更严重（均有显著差异）。所有儿童的鼻咽腔随年龄增长而增大，7岁以后腺样体体积和鼻咽阻塞程度减小。
