In addition to the CTP-positive rate, audio-vestibular symptoms were compared between CTP-positive and -negative cases.Results: 8-50% of patients in category 1 (trauma, middle and inner ear disease cases), and about 20% of those in categories 2, 3 and 4 (external origin antecedent events, internal origin antecedent events, and without antecedent event, respectively) were positive for CTP. In category 1 cases, the earlier tested samples showed a higher CTP-positive rate, whereas no differences were observed in categories 2, 3 or 4. The characteristic clinical features in the earlier tested cases were nystagmus and fistula sign in CTP test-positive cases in category 1, and streaming water-like tinnitus in those in categories 2, 3 and 4.Conclusion: The present study clarified that CTP detection test-positive patients exist at considerable rates among patients with inner ear-related manifestations.ARTICLE HISTORY
