Perfil etiológico dos pacientes implantados do Programa de Implante Coclear

Abstract

A to investigate the major etiological agents that caused deafness in the studied population is of great relevance to prognostic and treatment purposes and it serves as sampling for future actions in the public health. Aim: to check the different hearing impairment etiologies of patients in the cochlear implant program; we studied the etiologies described in order to correlate etiology with age. Materials and Methods Results and conclusion:Unknown etiology prevailed as main cause, and this indicates the need to continue carrying out genetic studies in those cases of congenital sensorineural hearing loss without an apparent cause in order to trace and etiological profile. Rubella was the second most found cause, and for this etiology there already are preventive measures as there are for meningitis. Even then, the incidences of these diseases remain high. In the correlation of the different etiologies and age ranges, we noticed varied etiologies when we compared children, young adults, adults and the elderly. Braz J Otorhinolaryngol. 2011;77(1):13-8.

Auditory Speech Perception Tests in Relation to the Coding Strategy in Cochlear Implant

“…The mean thresholds observed in CI users in the present study was 27dB, in agreement with data reported by Santos et al 4 , who stated that, despite the different types of CI, the audiometric thresholds did not exceed 40dB. The etiology most frequently detected was that of unknown cause (idiopathic), observed in 50% of the participants, a result that agrees with the study of Calhau et al 23 , who also observed deafness of idiopathic cause in 40% of their patients.…”

Cochlear implants: our experience and literature review

“…The diagnosis of the causes was diversified, 22.2% maternal German measles, 22.2% cytomegalovirus, 22.2% for ototoxicity, 22.2% meningitis, and 11.1% sudden deafness. This result also goes against the findings of other studies, which show etiology unknown as the main cause of sensorioneural deafness 8 . The age at the time of surgery varied from 2 to 46 years, being that 6 of 9 patients had age varying from 2 to 9 years, a fact observed in other studies, where the surgery is carried out with greater frequency in children with deafness prelingual 8 .…”

Estudo genético de perdas auditivas hereditárias mediante novas tecnologias baseadas em array-CGH e next-generation sequencing

“…Nos países desenvolvidos, mais de 60% dos casos de perda auditiva resultam de causas genéticas (Rodríguez-Ballesteros et al, 2008). Entretanto, no Brasil, os fatores ambientais ainda superam os de origem genética (Simões & Maciel-Guerra, 1992;Pupo et al, 2008;Calháu et al, 2011;Colella-Santos et al, 2011). À medida que vêm sendo implantadas melhorias na área da saúde, e com o avanço e aprofundamento nos estudos genéticos relacionados às perdas auditivas, a proporção de causas genéticas tende a aumentar.…”
