Stenosis of the cartilaginous auditory canal is still difficult to resolve and many techniques of plastic surgery have been proposed. Our experience was first built up in treatment of stenosis of the tracheostomy in patients who had undergone laryngectomy. Since it is simple and effective, we have transferred and modified the technique to the treatment of stenosis of the external auditory canal and of the concha. Fourteen patients with stenosis of the cartilaginous auditory canal (diameters of the stenosis prior to surgery varied from 19 to 78.5 mm(2)) underwent day-surgery conchomeatoplasty under local anaesthesia. Eight months after the operation, the results are good. Following surgery, the surface of the auditory canal, measured at the narrowest point of the external auditory meatus, varied from a minimum of 113 mm(2) to a maximum of 254 mm(2). The technique we propose to correct the stenosis of the external auditory canal is easy to carry out, short, and may be performed under local anaesthesia. Lastly, the auditory canal and the ear auricle have a good blood supply, thus ensuring the flaps will survive.
软骨性耳道狭窄仍然难以解决，许多整形外科技术已经被提出。我们的经验首先是在接受过喉切除术的患者的气管造口术狭窄的治疗中建立起来的。由于它简单有效，我们已经将技术转移并修改用于治疗外耳道口和耳廓的狭窄。14 名软骨性耳道狭窄患者（手术前狭窄直径从 19 到 78.5mm²不等）在局部麻醉下接受日间手术耳廓成形术。手术后 8 个月，结果良好。手术后，外耳道最狭窄处的耳道表面面积从最小的 113mm²到最大的 254mm²不等。我们提出的纠正外耳道口狭窄的技术易于实施，耗时短，并且可以在局部麻醉下进行。最后，耳道和耳郭有良好的血液供应，从而确保皮瓣能够存活。
