Twenty one cases of revision tympanomastoidectomies operated by a junior staff were analyzed according to the patient's symptom, preoperative otologist's view and operative finding. Otorrhea (11 cases) and cholesteatoma (12 cases) were the main reasons for revision operation by patients and surgeon, and the blockage of ventilatory route from the eustachian tube to the middle ear space was the most common causactive underlying pathology.
