“…10,11 However, criticisms of these strategies exist because of the risk of delayed sensorineural hearing loss caused by the potentially pernicious environment of an infected open mastoid cavity and the residual matrix. 7,12 Alternatively, one-stage complete resection of the cholesteatoma matrix on the fistula has been recommended by some authors because of effective disease control and longterm hearing preservation, 13,14 in which the hearing outcomes were independent of complete matrix removal from the top of the fistula post-operatively. 7 Building on these recommendations, the results of our study, which has a level of evidence of 3, demonstrate that a one-stage complete resection of the matrix on the fistula was safe and that the surgical technique itself did not result in iatrogenic sensorineural deafness, which is a complication in patients with cholesteatoma and a labyrinthine fistula.…”

Objective This study aimed to compare the pre- and post-operative vestibular and equilibrium functions of patients with cholesteatoma-induced labyrinthine fistulas who underwent different management methods. Methods Data from 49 patients with cholesteatoma-induced labyrinthine fistulas who underwent one of three surgical procedures were retrospectively analysed. The three management options were fistula repair, obliteration and canal occlusion. Results Patients underwent fistula repair (n = 8), canal occlusion (n = 18) or obliteration procedures (n = 23). Patients in the fistula repair and canal occlusion groups suffered from post-operative vertigo and imbalance, which persisted for longer than in those in the obliteration group. Despite receiving different management strategies, all patients achieved complete recovery of equilibrium functions through persistent efforts in rehabilitation exercises. Conclusion Complete removal of the cholesteatoma matrix overlying the fistula is reliable for preventing iatrogenic hearing deterioration due to unremitting labyrinthitis. Thus, among the three fistula treatments, obliteration is the optimal method for preserving post-operative vestibular functions.
