Objective To observe the clinical efficiency of batroxobin combined with methylprednisolone in the treatment of sudden hearing loss. Methods A retrospective analysis was performed on 110 patients with (118 ears) sudden deafness in the Hainan Branch of Chinese PLA General Hospital from August 2012 to October 2014. According to their treatment regimen, they were assigned into observation group (n＝57, 62 ears, conventional treatment plus batroxobin and methylprednisolone) and control group (n＝53, 56 ears, only conventional treatment). The cohort was also divided into 4 groups according to the pure tone hearing threshold graphics, that is, low frequency hearing loss (38 ears), high frequency hearing loss (51 ears), flat type (12 ears), and total deafness (17 ears). Results After treatment, the observation group had 11 ears (17.7%) recovered, 32 ears (51.6%) markedly effective, 16 ears (25.8%) effective, and 3 ears (4.8%) invalid, with a total efficiency rate of 95.16%. There were 6 ears (10.7%) recovered, 21 ears (37.5%) markedly effective, 20 ears (35.7%) effective, and 9 ears (16.1%) invalid in the control group (total efficiency rate 83.93%). Significant difference was seen in the total efficiency rate between 2 groups (P＜0.05). Low frequency hearing loss type deafness had better prognosis, flat type deafness had good, high frequency hearing loss type deafness had bad, and total deafness type hearing loss type deafness had worst prognosis. There were significant differences in the efficiency of different treatment regimen for different deafness types between 2 groups (P＜0.05). Conclusion Combination of batroxobin and methylprednisolone is efficient and safe in the treatment of sudden hearing loss, and worthy of clinical promotion. Different types of sudden deafness have widely various prognosis.
