Abstract
OBJECTIVE To explore the characteristics,the therapeutic methods and effects of external auditory canal cholesteatoma(EACC).METHODS The clinical records of 66 cases diagnosed with EACC between January 2014 and January 2016 were retrospectively reviewed.Their ages ranged from 3 to 75 years (average 32.5± 1.68 years).There were 32 men and 34 women.According to Holt's grading criteria for EACC,there were 10 ears of phase Ⅰ,26 ears of phase Ⅱ,and 30 ears of phase Ⅲ.The phase Ⅰ ears were treated by removing cholesteatoma from the external auditory canal.Canaloplasty and/or tympanoplasty were performed in phase Ⅱ ears.The phase Ⅲ ears were managed by canaloplasty and tympanoplasty or radical mastoidectomy.The duration of follow-up ranged from 6 months to 2 years.RESULTS In the present study,hearing impairment was the most common symptoms(61 ears,92.42％),other symptoms include ear fullness(49 cases,74.24％),otalgia(45 cases,68.18％),otorrhea(44 cases,66.67％),peripheral facial paralysis(lcase,1.52％).There were 2 recurrences at 11 and 14 months postoperatively.All the other ears remained patent and dry with good skin coverage.Apart from 5 patients who underwent radical mastoidectomy,the rest of patients obtained intact tympanic membranes and impoved hearing.Facial nerve function of 1 patient with peripheral facial paralysis returned to normal6 months after operation.CONCLUSION The EACC can easily damage the bony meatus of external auditory canal and the adjacent structure.The clinical stages can help identify the primary lesions and determine the choice of the best treatment approach.关键词
