Abstract:
Objective:To investigate the clinical characteristics and treatment outcomes of patients with blast-induced hearing loss（BIHL）. Methods:The clinical features, laboratory parameters, audiometric profiles, and treatment efficacy of patients with blast induced hearing loss and those with idiopathic sudden hearing loss（ISHL） were analyzed using t-tests, Wilcoxon rank-sum tests, and chi-square tests, with a significance level set at P<0.05. Results:A total of 59 patients in the BIHL group and 117 patients in the ISHL group were included in this study. The mean age of the BIHL group was（39.07±14.49） years, comprising 45 males and 14 females. After the blast, 21 patients went to the hospital within the initial 14-day period, and an additional 38 patients seeking admission thereafter. In the BIHL group, 33 patients had unilateral hearing loss with PTA of （50.30±28.85） dB HL, while 26 had bilateral hearing loss with a PTA of（44.54±26.22） dB HL. In comparison, among the ISHL group, 112 patients had unilateral hearing loss with a PTA of（56.28±14.19） dB HL, and 5 had bilateral involvement with a PTA of（56.25±35.14） dB HL. The effective treatment rate within 14 days for the BIHL group was 31.8%, while for the ISHL group, the effective rate within 14 days was 77.0%. Conclusion:Blast-induced hearing loss is caused by exposure to high-intensity noise. The overall treatment effectiveness during hospitalization is lower compared to idiopathic sudden hearing loss, and the treatment window is shorter. Therefore, greater emphasis should be placed on prevention.
