ObjectiveTo discuss the clinical characteristics and surgical management of labyrinthine fistula caused by chronic suppurative otitis media (CSOM).MethodsClinical data of 20 cases with labyrinthine fistula caused by CSOM and surgically treated from 2006 to 2011 was analyzed retrospectively. Onestage repair of fistula was performed in all cases.ResultsAll patients were followed up for six months to five years postoperatively. Vertigo got eliminated or improved in all cases. The postoperative average bone conduction thresholds (0.5, 1, 2 and 4 kHz) showed no change in 12 ears, improvement in 2 ears and slight decline in 6 ears.ConclusionsHigh attention should be paid to the possibility of labyrinthine fistula in patients with CSOM. Successful surgical management should include thorough removal of inflammatory lesion and complete repair of fistula.
