Conchomeatoplasty: a new technique

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 mm2) underwent daysurgery 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 mm2 to a maximum of 254 mm2. 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.
