Brainstem Electric Response Audiometry (BERA)in the Evaluation of Hearing Loss in Infants with Cleft Palate
نویسندگان
چکیده
It has been estimated that one child in 500 to 750 live births is born with a cleft palate (Rood & Stool, 1981). A high incidence of middle ear pathology is known to be associated with this problem (Bluestone, 1971). It is generally accepted that this population suffers from Eustachian tube dysfunction which leads in turn to the development of middle ear effusions and conductive hearing loss. The various underlying causes that have been postulated are related either to an anatomic malformation of the palate and tube or a functional deficiency of their musculature (Bluestone, 1971; Rood & Stool, 1981).

Background: Loss of hearing is a non-visible disability (NVD) and the second most common congenital pathology. Apart from hearing loss, further disability in these domains has been reported like development of language, speech, cognition, and other evolving domains. These can be prevented by early identification and intervention. The aim of this study was to assess the outcomes of neonatal hear...

Hearing is the link by which the newborn comes in contact with the world of sound and language. Sense of hearing is a gift to mankind from god, as hearing and speech are the cornerstones of communication. Speech is intimately related to hearing because those with impaired hearing often have speech delay. The aim of the study was to analyze the effectiveness of BERA (Brain stem evoked response a...

One of the most important applications of the Brainstem evoked response audiometry (ABR) is in the evaluation of hearing loss in children. Today the ABR is also indicated in the screening of cochleo-vestibular syndromes to detect retrocochlear lesions, to monitor patients in a coma (brain death), in monitoring the brainstem during skull base surgery, etc. Among the many BERA qualities, is its c...
