Otological accident resulting from mine explosions are polymorphous mainly affecting the deployed military personal in our country. A delayed treatment, usually by lack of knowledge and (or the injuries considered to be more serious, can worsen the auditory prognosis).
We report a list of 90 patients treated for ear blast injury secondary caused by terrorist acts at the ENT service of the Military hospital of Tunis between 2011 and 2017. A minimal of 12 months follow-up was required. 64% of the patients were less than 10 meters from the center of explosion and 30 within 5 meters. Initial otoscopic examination revealed tympanic perforation in 15 patients, eighth of tem were bilateral. The rest of the reports revealed secondary injuries due to patients falling on earth (tertiary blast) and / or screened by speed projected debris ( secondary blast)
All patients underwent clinical evaluation and an audiometric exploration before and after treatment. Hearing loss average was 40 dB and tinnitus were present in 80% of patients. Treatment was based on intravenous corticosteroids wit or without hyperbaric oxygen therapy (53 cases). At 12 months after the accident, hearing gain average was 20 dB and only 37.5% of patients reported decrease in tinnitus. Evolution was however multifactorial.
