The aim of the study was to review the literature of tympanoscierosis especially its pathogenesis, to study the general incidence of tympanoscierosis among patients with chronic suppurative otitis media (CSOM), its association with cholesteatoma and also the type of hearing loss as well as its relation to the degree and site of tympanosclerosis.Seven hundred and seventy-five patients with CSOM were studied retrospectively. A full history was taken and thorough ENT examinations were carried out. Pure tone audiograms (PTA) of all patients were done and analysed. The operative finding of tympanosclerosis as well as middle-ear status were inspected.The incidence of tympanosclerosis was found to be 11.6 per cent (90 patients out of 775 CSOM cases). Most tympanosclerosis cases had dry ear, (85.6 per cent). Of the 57.8 per cent who had myringosclerosis, their PTA showed an AB gap 20–40 dB. When sclerosis affect both the tympanic membrane and middle ear, 61 per cent of patients had an AB gap >40 dB. The association of cholesteatoma and tympanosclerosis may be regarded as uncommon, 2.2 per cent.The exact aetiology and pathogenesis of tympanosclerosis is as yet not well known. Our study concentrated on the clinical picture of tympanosclerosis among patients with CSOM. The majority of hearing loss associated with tympanosclerosis was of the conductive type.

The professional content of sleep medicine has grown significantly over the past few decades, warranting the recognition of sleep medicine as an independent specialty. Because the practice of sleep medicine has expanded in Saudi Arabia over the past few years, a national regulation system to license and ascertain the competence of sleep medicine physicians and technologists has become essential. Recently, the Saudi Commission for Health Specialties formed the National Committee for the Accreditation of Sleep Medicine Practice and developed national accreditation criteria. This paper presents the newly approved Saudi accreditation criteria for sleep medicine physicians and technologists.

BackgroundWorkplace safety has increased in many developed nations, but work-related injuries (WRIs) are on the rise. Globally, approximately 2.9 million fatal work-related injuries and diseases occurred in 2021, up from 1.1 million in 1999. MethodThis work employs a cross-sectional study using the open data published by the General Organization for Social Insurance (GOSI) on an annual basis for the years 2016 to 2021.The data from one year in each category were compared with a reference year by using the index value method and simple linear regression. Additionally, the researchers calculated the injury-to-worker ratio for each year.
