Abstract
Objectives: to determine the etiology of hearing loss among children presenting at Al –Thawra Teaching Hospital in Sana’a, Yemen.
Patients and methods: a total of 580 children with hearing loss attended the ENT out-patient clinic in Al – Thawra Teaching Hospital during the period from January 2003 to December 2004. Patients were examined clinically and investigated by pure tone audiometry, tympanometry and auditory brain stem response (ABR) when indicated.
Results: A proportion of 68.3% of children with hearing loss were aged between 5-15 years at presentation. Males were 337(58.1%) and females were 243 (41.9%).
Of the 385(66.4%) children who were subjected to pure tone audiometery 282 (73.2%) had profound hearing loss, 71 (18.4%) had severe hearing loss and 32 (8.3%) had moderately severe hearing loss.
Causes of hearing loss were: unknown in 238(41.0%), meningitis in 122(21.0%), hereditary in 76(13.1%), ototoxicity in 47 (8.1%) and febrile convulsion in 35(6.0%).
Consanguinity was recorded in the parents of 309(53.3%) children. Of them 192 (62.1%) married to their first cousins and 117 (37.9%) to their relatives.
Conclusion: the highest range of presentation of children with hearing loss was between 5-15 years old. The most common causes were unknown, meningitis, hereditary and ototoxicity. Consanguinity was reported by more than half of the parents. Majority of the children were with profound type of hearing loss.

... In a previous study, it was shown that hearing loss may have been caused by higher rates of pre-and post-natal childhood infections such as meningitis, mumps, measles and rubella, and from the use of ototoxic drugs [9]. In another study, disabling hearing impairment was identified as a major health problem in Yemeni children with chronic suppurative otitis media [10]. ...
Al-Mahbashi., et al. Abstract Purpose: The objective of this survey is to analyze the Otorhinolaryngology Care in Yemen. The survey was undertaken to provide the foundation for an evidence-based plan for improving ear, nose, and throat (ENT) care services in Yemen specially ear and hearing care. Methodology: To review ENT services for the year 2020, standardized questionnaire was distributed to 248 ENT clinics in 22 different Yemeni governorates. Results: Yemen has 203 Otorhinolaryngologists, 5 of them are Audiologists, 60 trainees and 45 general practitioners who provided ENT care. Overall, there are 0.7 ENT practitioners per 100,000 population. Sana'a (capital city), the governorates of Aden, Hadram-out, and Ibb have about 75% of the practicing otolaryngologists in the country. As of 2020, there are 248 ENT clinics. Among these, 75% are private facilities. In addition, there are 55 surgical otomicroscope, of which 30 (55%) are in Sana'a. In 2019, the handicap ward rehabilitation fund together with NGOs cover only around 12% of hearing handicaps cases.. Conclusion: The level of ENT care in Yemen is relatively lower than that in other countries of the Eastern Mediterranean Region (EMR). Improvements are necessary with respect to the number and level of training of otolaryngologists, and distribution of ENT care personnel, facilities, equipments, and support staff especially in rural areas. A national evidence-based plan for prevention of deafness is also needed.
