Analysis of the outcomes of reconstruction for stenosis of the ear canal in 20 patients revealed that the key step in the procedure after the stenotic meatus and ear canal skin have been removed (in the process accomplishing a wide meatoplasty) is widening the posterior bony canal wall until some mastoid cells are encountered. After the tympanic membrane has been deepithelialized, the bony canal should be lined with two separate pieces of split-thickness skin grafts and protected with Silastic sheeting and packing. Average follow-up of 3 1/3 years revealed that 2 ear canals have restenosed, 2 have partially restenosed, and 18 have healed. Of the 22 ears, 15 have had hearing improved to within 25 dB SRT or better, 5 have moderate hearing improvement, and 2 have no improvement. There were no complications.
对20例耳道狭窄重建手术结果的分析显示，在去除狭窄的外耳道和耳道皮肤（在此过程中完成广泛的外耳道成形术）后，该手术的关键步骤是扩大后骨耳道壁，直到遇到一些乳突气房。在鼓膜去上皮化后，骨耳道应用两片单独的中厚皮片覆盖，并用硅橡胶片和填充物保护。平均随访3又1/3年发现，2个耳道再次狭窄，2个部分再次狭窄，18个愈合。在22只耳朵中，15只听力改善到言语识别阈（SRT）在25dB以内或更好，5只听力有中度改善，2只无改善。无并发症发生。
