Objective: The objective of this study was to assess vestibular functions in patients with chronic suppurative otitis media (CSOM) with and without sensorineural hearing loss. Study Design: This was a prospective case study performed at a tertiary referral university hospital. Sixty patients with CSOM were included, and patients with a history of head trauma, diabetes, hypertension, previous ear surgery, use of ototoxic drugs, neurological deficits and suspected fistulae were excluded. Patients and Methods: The patients underwent basic audiological evaluation, and clinical and instrumental vestibular evaluation. The incidence and extent of vestibular dysfunction in patients with CSOM were analyzed. Results: A total of 42 males and 16 females with a mean age of 29.5 years were included in this study. Forty ears had tubotympanic disease and 19 had cholesteatoma. There were 14 ears with sensorineural hearing loss. A positive history of vertigo was reported in 53.5% of the cases. Rotatory chair abnormalities were found in 70% of the cases, caloric hypofunction was found in 61.6%, and vestibular myogenic evoked potentials were abnormal in 25%. The only positive correlation with vestibular dysfunction was the duration of disease. Conclusions: The vestibular system is significantly affected in cases with CSOM. Both semicircular canals and the saccule are affected. All patients with long-standing CSOM should be evaluated for vestibular dysfunction irrespective of their hearing levels.
This presentation of the public health impact of hearing impairment highlights the important elements of interaction between the disability and community. Objectives: Retrospective study to identify the size of the problem of hearing loss, illustrating not only the magnitude but also the serious effect of the lack of reliable data concerning this matter. It highlights the challenges met within a mid-economy community regarding the handling of the impact of the disability. The Egyptian data is given as an example of the situation in a mid-economy community. Study Design: A brief introduction of some epidemiological factors of hearing impairment is presented including the size of the problem in Egypt. Data of the neonatal hearing screening program of the Audiology Unit, Ain Shams University, is presented. The impact of the disability is then discussed in relation to the age of onset and the degree and type of hearing loss. This is followed by the description of the nature and effect of the disability in the different age groups. A discussion of the various factors that may modify the capability of the community to deal with such disability follows. This includes various economic indices with their possible limitations on the part of the community. Such a briefing illustrates the challenges met in the rehabilitation of the deaf and the hearing-impaired in a developing mid-economy country. The broad lines of the management of the problem both at the prophylactic as well as the rehabilitative levels are discussed. A final remark on recommendations and possible future development in a developing country is presented.
Aim. To compare targeted neonatal hearing screening (TNHS) and universal neonatal hearing screening (UNHS) since many developing countries, including Egypt, implement selective screening for high-risk neonates. Methods. 150 neonates were assessed; 50 full terms consecutively admitted to the well-baby nursery and 100 neonates consecutively admitted to neonatal intensive care unit (NICU), Ain Shams University. Patients were further subdivided into high-risk group which included 50 neonates with multiple risk factors for hearing loss and low risk group which included 50 neonates with only one risk factor. Transient evoked otoacoustic emissions (TEOAEs) were used for hearing screening. Auditory brain response (ABR) was performed 3 months later for failed TEOAEs. Results. The most frequent risk factor was consanguinity (46%). In the well-baby population, 16% failed TEOAEs. In the NICU, 30% of the low risk and 38% of the high risk groups failed TEOAEs. Regarding ABR, failed results were 12%, 10%, and 8% in the high-risk, low-risk, and healthy groups, respectively. Conclusion. The use of TNHS would have missed 8% of neonates from the well-baby group who actually had PCHL (permanent congenital hearing loss). The use of UNHS would identify all cases with PCHL, allowing for early intervention and follow-up.
