The purpose of this study is to evaluate the efficiency of conservative dilute vinegar therapy in the management of spontaneous external auditory canal cholesteatoma (EACC). From 2000 to 2007, 19 patients presented to our clinic with spontaneous EACC. EACC was divided into four grades based on the temporal bone computed tomography: grade I with flattening of bony external canal, grade II with partial destruction of inferior bony canal, grade III with total destruction of inferior bony canal and grade IV with bony destruction into the middle ear and mastoid cavity. Clinical findings and treatment results were recorded. Microscopic local cleansing and dilute vinegar therapy was conducted in the ears with grades I, II and III. Combined mastoid surgery and dilute vinegar therapy was conducted in four ears with stage IV. There were no recurrences after average of 31 months follow-up. Spontaneous EACC can be effectively controlled with dilute vinegar therapy after microscopic local cleansing. However, surgery must be considered in the cases which have involved the mastoid and middle ear. Dilute vinegar therapy in combination with microscopic local cleansing was effective in the management of spontaneous EACC. Dilute vinegar therapy is an easy, cost-effective, and home-based cleansing method to prevent EACC and promotes healing. However, long-term follow-up may reveal frequent recurrence of cholesteatoma debris and involvement of middle ear or mastoid cavity, and then meticulous debridement with skin graft or surgical intervention should be considered.
