3.1 The profile of clinical data in each group
A total of 124 patients were enrolled and randomly divided into the ITD group and the ITL group. The ITD group was further randomly divided into the ITD1 (2mg/ml) and ITD2 (5mg/ml) groups. All the patients (174 ears) with Méniere’s disease (59 men, 65 women; age range: 21 to 81 years old )were treated with IT. The time between development of otologic complaints and ITD treatment ranged from 6 months to 5 years and 2 months. Prior to the administration of IT, all patients had been treated with other medications. All 124 had been treated with courses (often multiple) of oral medicine. The comparison of the general clinical index of each group before treatment (table 1 and table 2) showed no statistically significant difference (P > 0.05), indicating that the two groups had good equilibrium and were comparable.
