A case with postsurgical stenosis of the external auditory canal is reported. The patient was a 26-year-old female complaining of left progressive conductive deafness, tinnitus, pain in the postauricular region and dizziness of 6 months' duration. Cholesteatoma with intact tympanic membrane was suspected. Tympanatomy revealed tympanosclerosis in the middle ear cavity, especially in the epitympanum. The stenosis of the external auditory canal occurred approximately 2 months after the middle ear surgery. Following the extirpation of the cicatricial tissues of the stenosed lesions, a stent of microporous expanded polytetrafuruoroethylene (EPTFE) was inserted into the opened external auditory canal for approximately 7 months. The external auditory canal remained wide open after removal of the stent. Histopathology of the stenosed lesions showed fibrosis with hyaline degeneration. It is of great interest to note that hyaline degeneration was noted in both the tympanosclerotic tissue of the epitymanic cavity and the cicatricial tissue of the stenosed external auditory canal. A causative relationship may possibly exist between these two lesions.
