Epitympanoplasty with Mastoid Obliteration Technique in Only/Better Hearing Ears / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: Sensorineural hearing loss is one of serious complications caused after the operation of chronic ear disease. In only/better hearing ears, it is important to minimize the chances of developing a severe hearing loss and to stop the progression of disease. We report the results of performing epitympanoplasty with mastoid obliteration in the only/better hearing ear with cholesteatoma. SUBJECTS AND METHOD: From February 11, 1996 to April 16, 2003, epitympanoplasty and mastoid obliteration was performed for 6 patients with the only hearing ear and 2 with a better hearing ear. In the only/better hearing ears, 7 cases had cholesteatoma and 1 case had adhesive otitis media. The other ears of the 5 cases had previously received canal wall down mastoidectomy, 2 cases sensorineural hearing loss and 1 case both epitympanoplasty and mastoid obliteration. The observation period ranged from 7 to 99 months, with the average of 45 months. RESULTS: One-staged operation was performed on all 8 patients. Four cases got total ossicular replacement prosthesis, 3 cases received partial ossicular replacement prosthesis, and 1 case received autologous cartilage short columellization. After each operation, all patients obtained a dry, safe, self-cleansing ear and recurrence did not occur. The hearing results in this series showed that the air conduction thresholds, bone conduction thresholds and air-bone gaps were preserved in 7 cases, but became worse in one patient. Two patients did not need to use hearing aids, five patients used an hearing aid of in-the-canal (ITC) type, one patient used a hearing aid of completely-in the canal (CIC) type. CONCLUSION: Epitympanoplasty with mastoid obliteration in the only/better hearing not only can stop the progression of cholesteatoma, but also can preserve hearing of patients.
