Objective: This study aimed to assess the experiences and outcomes of patients who underwent surgical repair of a perilymph fistula in Norfolk, UK.
Methods: The study involved a retrospective questionnaire-based patient survey and case note review of patients who had undergone tympanotomy and perilymph fistula repair between 1998 and 2012 in two district general hospitals.
Results: Fourteen patients underwent 20 procedures, of whom 7 completed the pre- and post-operative Vertigo Symptom Scale. In five patients, there was no obvious precipitating cause. Perilymph fistula was precipitated by noise in one patient, by a pressure-increasing event in six patients and by trauma in two patients. The Vertigo Symptom Scale scores showed a statistically significant improvement following surgical repair, from a median of 67 (out of 175) pre-operatively to 19 post-operatively.
Conclusion: In selected patients with vertigo, perilymph fistula should be considered; surgical repair can significantly improve symptoms.
