Abstract
Background:External auditory canal (EAC) cholesteatoma (EACC) is rare and its treatment for different lesions has not yet been standardized. Objective:This study aimed to explore the clinical features of EACC with bone erosion, and to assess the curative effect of initial complete cholesteatoma debridement (ICCD). Material and methods:Clinical characteristics and prognosis of 41 ears were analyzed retrospectively. Results:The bone erosion of the EAC was most commonly affected on the posterior wall (37 ears), next by the inferior wall (34 ears), the anterior wall (30 ears) and the superior wall (23 ears). Hearing loss (36 ears) was the most common symptom, followed by otalgia (33 ears), otorrhea (18 ears), tinnitus (11 ears) and pruritus (3 ears). The hearing impairment of mean air conduction and air-bone gaps were improved from 39.2 dB to 22.7 dB, and 23.5 dB to 7.1 dB after the ICCD procedure, respectively. Four ears presented recurrence during the follow-up time and accepted a revision-debridement. Conclusion and significance:The ICCD might be applicable in the treatment of patients in the early stages and with non-extensive bone defect; however, close and long-term surveillance is essential and serial debridement is probable.This publication has 18 references indexed in Scilit:
