The objective of this study was to assess the otological damage of military music professionals in Cotonou. <strong>Methods:</strong> This was an analytical cross-sectional study carried out from July 15 to November 15, 2019. It focused on soldiers from the Music Squadron and the first Motorized Intervention Battalion of Camp Guézo in Cotonou. <strong>Results:</strong> 110 soldiers were included. The mean age was 34.3 ± 6.2 years. The sex ratio was 17.3. The instruments used were wind (74.5%), percussion (23.6%) and string (1.8%). The average length of service in the Music Squadron was 11.5 ± 6.7 years with extremes of 1 year and 25 years. They practiced military music for an average of 4.58 hours per day for 4 days per week. The mean sonometric measurement during training ranged from 89.1 dB (A) to 116.4 dB (A). Hearing loss was predominant in the military musicians group and was mild degree bilaterally (p = 0.002) and perceptual type (p = 0.007). <strong>Conclusion:</strong> Military musicians are exposed to high noise levels, putting them at risk of developing hearing problems that may limit their performance. The main otological morbidity found was hearing loss associated with a few cases of tinnitus and headache.展开更多

Its usefulness and efficiency are certain, but it needs regular assessments. <strong>Aim:</strong> to determine the frequency of tracheotomies in ENT at CNHU of Cotonou, identify the indications, surgical technics and the postoperative course. <strong>Materials and methods:</strong> the study was retrospective, based on files of patients who have had tracheotomies for ten years since 2010. <strong>Results:</strong> in 10 years, 105 tracheotomies were performed for 99 patients, average 10 to 11 per year. Patients were male in 61.9%. Extreme of age where 09 months and 80 years old. Children under15 were concerned in 41.9%, while patients from 45 to 64 years old in 33.3%. Emergency tracheotomy represented 76%. Causes were tumors in 62.8%. Laryngeal papillomatosis was the predominant tumor in children;28 cases or 26.67%. In adults, larynx cancer represented 20%. Skin incisions were horizontal in 94.3%. Tracheal opening was “H-shaped” in 92.4%. Complications occurred in 28.6%. They included granuloma (13.3%) and oeso-tracheal fistula (1.9%). Decanulation was possible in 87.6%, but it was more difficult in children. <strong>Conclusion:</strong> tracheotomy was an act of rescue in our practice.展开更多
