External auditory canal cholesteatoma: classification and management
Keywords:Ear canal, Clinical findings, Ear discharge, Classification, Hearing loss, Extension
Background: External auditory canal cholesteatoma (EACC) is a disease characterized by the accumulation of keratin in the ear canal and erosion of the bony wall. Etiologically, it may be primary or secondary. It presents with ear discharge and pain. Distinction from similar conditions is crucial for appropriate treatment. This study evaluates the EACC. Its purpose is to suggest categories based on disease extent. This study aimed to evaluate the presentation, diagnosis, and treatment of EACC. The goal was to classify EACC based on disease severity and propose treatment approaches.
Methods: A retrospective review of medical records for patients diagnosed with EACC over ten years. Clinical data were examined for the presentation, clinical findings, etiology, and treatment. We simplified the approach by dividing the disease into three categories: Category 1, confined to the ear canal; Category 2, eroded the canal wall; Category 3, extended to adjacent structures.
Results: 18 patients were included in the study. Ear discharge and otalgia were the most common symptoms. Etiological classification of the disease identified most as secondary EACC. Two cases were assigned to Category 1, six to Category 2, and ten to Category 3.
Conclusions: Common symptoms of EACC are ear discharge, pain, and hearing loss. Our study categorizes the condition into three categories based on severity, extension, and treatment strategies. Most cases were assigned to category 3 and extended into adjacent structures.
