OBJECTIVE: Although many reports describe the short-term hearing outcomes of surgically managed labyrinthine fistulae, the long-term results remain unknown. We reviewed the long-term postoperative hearing outcomes of 14 ears of patients with cholesteatoma and labyrinthine fistulae.
METHODS: Between 1996 and 2010, 84 patients with cholesteatoma and labyrinthine fistula underwent tympanoplasty at Hyogo College of Medicine Hospital. Fistulae were located in the lateral semicircular canal in all patients and in the superior semicircular canal in one. Fourteen patients were followed up for more than 5 years.
RESULTS: The postoperative air-bone gap was ≤10dB in one patient, between 11 and 20dB in seven, between 21 and 30dB in four, and ≥31dB in two. Mean bone-conduction hearing levels on the operated side had deteriorated by 3, -1 and -2dB at 1, 2 and 4kHz, respectively at 1 year postoperatively, and by 8, 6 and 2dB at 1, 2 and 4kHz, at 5 years postoperatively. Bone-conduction hearing levels at 1 and 2kHz were significantly deteriorated at 5 years postoperatively, compared with baseline and 1 year (P<0.05).
