Методы хирургической коррекции рубцовых процессов наружного слухового прохода

Abstract

Cicatricial processes of the external auditory canal (EAC) are a complex multi-component problem for patients and ENT specialists. In most cases, the pathology develops as a result of inflammatory processes (chronic and recurring diffuse external otitis media, perichondritis and periostitis, chronic suppurative otitis media, eczematous dermatitis, recurrent furunculosis), injury or surgery. The analysis of global data showed that pathology has a high tendency to relapse in the long term. The article provides a literature review of surgical correction of cicatricial processes in the external auditory canal. The authors provided stage-by-stage development of surgical technique, the specificity of the external auditory canal anatomy, surgical options, types of transplantation of various flaps and stenting techniques. The article presents a comparative table reflecting the results of surgical intervention and the frequency of relapse of cicatricial processes. It is concluded that surgical correction should include complete resection of the atretic mass, significant EAC expansion and the closure of the exposed bone sites with a graft. Despite the variety of approaches to surgical intervention and the skin graft types, the authors cannot draw a single conclusion, which, subsequently, does not allow generating a unified method of correction of cicatricial processes in the external auditory canal.
