Grade II and III (according to Sadé's classification) retraction pockets (RPs) in 40 ears of 30 children were excised transmeatally with simultaneous ventilation tube insertion. At a mean follow-up of 16.1 months, an intact tympanic membrane and mild, grade I retractions not requiring treatment were observed in 32 ears (80%). The mean air-bone gap had decreased from 22.4 to 9.7 dB. Two residual perforations and six recurrent grade II RPs were detected, all these eight ears undergoing further surgery. The second surgery solved both of the residual perforations and four of the six grade II recurrences. The age of the children did not influence the success rate, whereas bilateral pathology, a higher grade and more extensive RPs were associated with a higher rate of unsuccessful cases. A staging system is introduced to ease the selection of candidates with a good prognosis for this procedure.
经 Sade 分级为 II 级和 III 级（II 级和 III 级）的回缩袋（RP）在 30 名儿童的 40 只耳朵中经鼓膜切开术同时进行通气管插入术切除。平均随访 16.1 个月后，32 只耳朵（80%）观察到完整的鼓膜和轻度、I 级的无需治疗的回缩。平均气骨导差从 22.4dB 降至 9.7dB。检测到 2 个残余穿孔和 6 个复发性 II 级 RP，这 8 只耳朵均接受了进一步的手术。第二次手术解决了 2 个残余穿孔和 6 个 II 级复发中的 4 个。儿童的年龄并不影响成功率，而双侧病变、更高的分级和更广泛的 RP 与更高的失败率相关。引入了一种分期系统，以方便为该手术选择预后良好的患者。
