ABSTRACT

Hearing loss among schoolchildren in developing countries is reported to be a significant health problem. Data on child hearing loss in South Sinai, a remote governorate of Egypt, are lacking. Middle ear diseases and hearing impairment were assessed among 453 primary-school children aged 7-10 years in South Sinai [906 ears]. Otoscopic examination, tympanometry and pure tone audiometry [PTA] were done. Ear disease was found in 27.5% of the ears examined. The commonest cause was secretory otitis media [10.8%], followed by occluded earwax [9.5%]. Mild and moderate hearing loss affected 8.5% of the sample, while sensorineural hearing loss affected 2.4%; only 0.4% had moderate and severe hearing loss. Hearing impairment affects 19.3% of this age group in South Sinai. None of the children with hearing impairment had been previously diagnosed or was receiving treatment and support. Hearing and middle ear screening at schools is recommended for early detection and management of middle ear and hearing problems

ABSTRACT

Long latency auditory evoked potentials [LAEPs] were recorded in 20 right handed normal hearing adult subjects, 11 males and 9 females. Their ages ranged from 25 to 56 years. Five stimuli with different frequencies were used [click, 500, 1000, 2000 and 4000 Hz]. The response was present in all five different stimuli for all subjects. N1, P2 latencies were longest at 500 Hz, while N1-P2 amplitude was largest at 500 Hz. Females had shorter latencies and larger amplitude than males. Right ears showed shorter latencies and larger amplitude than left ears
