Objective: To determine the audiometric profile of deafness in our practice. Materials and Methods: Longitudinal prospective study was conducted out in the ENT department and cervicofacial surgery of Gabriel Toure University Hospital in Bamako, we made an exhaustive sampling of all the patients who consulted for hearing loss, tinnitus, vertigo, hiring report, medical expertise and whose deafness was confirmed to tonal audiometry with an age greater than or equal to 15 years. It was spread over 10 months (June 2016 to March 2017). A total of 200 patients were collected. Exclusion criteria were all patients under 15 years of age as well as deafness related to earwax or foreign bodies, and refusal to participate in the study Results: During our study period, 6055 outpatients were admitted out of which 734 patients underwent audiometric testing and 200 patients (3.30%) met our criteria. The male sex was the most represented with a rate of 60%. The sex ratio was 1.5 or 3 men for 2 women. The 15 to 25 age group was the most represented at 37.5%. The average age was 37.18 years old with extremes ranging from 15 to 83 years old. Pupils/students were the most represented with a rate of 29.5%, followed by housewives in 23%, farmers in 10.5% and military in 10%. As antecedent 26% of our patients had a chronic otitis media (OMC), against 23% who had no antecedent otological and 17% had a traumatic antecedent. Bilateral deafness was the most common with a rate of 64.5%. The mode of progressive appearance was the most frequent in 74.5%. As functional signs 46.22% of our patients had a hearing loss associated with tinnitus. Otoscopic examination was pathological in 34.5% of our patients. Mixed deafness was the most common in 43.35%, followed by perception deafness in 32.19% and transmission How to cite this paper:
Objective: To study the epidemiological, clinical and therapeutic aspects of hearing loss in 15-year-olds and over at the CHU GT of Bamako. Materials and Method: This is a longitudinal prospective study carried out in the ENT department of the University hospital Gabriel Toure in Bamako over 13 months (from September 2018 to September 2019). We carried out an exhaustive sampling of all the patients who consulted in the department for hearing loss and whose deafness was confirmed at pure tone audiometry with age greater than or equal to 15 years. The exclusion criteria were all patients under the age of 15 as well as a hearing loss related to earwax or foreign bodies and refusals to participate in the study. Results: Two hundred and thirty (230) patients were collected during the study. Dominated by the male sex with a sex ratio of 1.5 or 3 men for 2 women, with an average age of 38.16 ± 19 years with extremes ranging from 15 to 86 years. Among our patients, 37.40% had unilateral deafness, progressive installation evolving more than 12 weeks with a rate of cases had headaches 41% and had a history of chronic otitis media (CMO) 27%. There were a few cases of mixed type deafness, 30% had mild deafness, 22% moderate deafness and 40% severe deafness, according to the BIAP classification. Among our patients, 22.16% had conductive hearing loss, and those with sensorineural hearing loss accounted for 15.24%. Conclusion: Pure tone audiometry remains essential in the diagnosis of deafness.
