Hearing loss is one of the most common chronic health conditions and has important implications for the patient's quality of life. However, hearing loss is substantially underestimated and under treated. The purpose of this study was to determine the prevalence of sensorineural hearing loss among the workers in a steel rolling mill in Nigeria. Each of the 150 randomly selected subjects had a structured questionnaire administered to them, followed by a full otological examination. Of these, 116 had tympanometry and pure-tone audiometry. Also a noise mapping of their respective work units was done. The workers were exposed to noise levels varying from 49 to 93 dBA. About 28.2% of the 103 who had their audiogram analysed had mild to moderate sensorineural hearing loss in their better ear and 56.8% of them had mild to moderate sensorineural hearing loss in their worse ear. The pure-tone average and the average hearing thresholds at 4 kHz for the groups significantly increased with an increasing noise exposure level. The prevalence of sensorineural hearing loss among the study population is high; and noise exposure is at least contributory. Pre-employment and regular audiometry while on the job is highly recommended.

While noise is recognized as a hazard, initiatives are required to increase use of effective preventative measures.

Foreign bodies in the ear are relatively common in emergency medicine. However, attempts at removal made outside the healthcare setting by untrained persons can result in complications of varying degrees. We conducted a 3-year retrospective review of 123 cases of aural foreign bodies at our hospital in Nigeria. Our patient population was made up of 80 males and 43 females, aged 2 to 67 years (mean: 13.2); almost three-fourths of these patients were aged 15 years or younger. Only 40 of them (32.5%) presented to an otolaryngologist within 12 hours of foreign-body insertion. A total of 30 patients (24.4%) had initially undergone removal attempts by a non-otolaryngologist prior to receiving trained ENT care, and 23 of them experienced a total of 41 complications: 17 cases of canal abrasion, laceration, and/or bleeding, 8 cases of otitis externa, 6 cases of tympanic membrane perforation, 5 cases of impaired hearing, 3 cases of chronic suppurative otitis media, and 2 cases of middle ear involvement. Of the 93 patients who were seen by an otolaryngologist initially, only 6 (6.5%) developed a complication: 4 cases of canal abrasion, laceration, and/or bleeding and 2 cases of otitis externa. The difference in overall complication rates between patients treated by otolaryngologists and non-otolaryngologists was statistically significant ( p < 0.001). We conclude that attempts at removal by non-otolaryngologists can result in a high incidence of preventable complications.

These findings showed that there was a high prevalence of mild sensorineural hearing loss and significant hearing deterioration among workers, due to exposure to excessive noise over a two-year period. The study demonstrates the practical importance of serial audiometry for noise-exposed workers as a means of monitoring hearing deterioration. It is necessary to enforce existing occupational health laws in our industries in order to prevent noise-induced hearing loss, since it is eminently preventable.

Objective: Ear, nose, throat, head and neck injuries are a common otorhinolaryngology disorder worldwide. This study aimed at determining the prevalence, sociodemographic features, aetiology, clinical presentation management and outcome of injuries to the ear, nose, throat, head and neck region. Methods: This was a prospective study of patients with otorhinolaryngolology, head and neck injuries that presented at our tertiary health institution. Consented patients were studied between October 2015 and September 2017. Analysis of obtained data was done with SPSS version 16.0. Results: The prevalence of ear, nose, throat, head and neck injury was 9.4%. There were 63.5% males 36.5% females with male to female ratio of 1.5:1. Foreign bodies' impaction was the commonest cause of injury in 32.3% followed by road traffic accidents in 19.8%. Commonest anatomical region were ear and nose in 49.7% and 28.5% respectively. Common clinical features among the patients were pain in 46.5%, bleeding in 37.8% and foreign bodies' impaction in 32.3%. Presentations for otorhinolaryngology care among the patients were common in 95.1% acute injury than 4.9% chronic injury (13 weeks). Commonest associated complications of the injuries were otitis media in 18.8% others were 14.9% otitis externa, 9.4% perforated tympanic membrane and 6.3% epistaxis. Pre-hospital treatment in the patients was 67.4%. Major treatment offered to the patients was conservative/medical therapy in 28.8%. Conclusion: Ear, nose, throat, head and neck injuries are common in the otorhinolaryngology practice. Commonest causes are self inflicting foreign bodies' impaction and road traffic accident. Pre-hospital treatment among the patients was very high.
