Potencial evocado auditivo de tronco encefálico por via óssea em indivíduos com perda auditiva sensorioneural

Abstract: OBJETIVO: caracterizar os resultados do PEATE por via óssea em indivíduos com perda auditiva sensorioneural leve, comparando esses dados com o grupo controle, formado por indivíduos audiologicamente normais. MÉTODO: a amostra foi constituída por 40 adultos, de ambos os sexos, com faixa etária de 18 a 55 anos, distribuídos em um grupo controle de 30 indivíduos com audição normal e um grupo estudo composto de 10 indivíduos com perda auditiva sensorioneural de grau leve. O PEATE foi realizado com equipamento EP15… Show more

“…This characteristic is reported as induced by high sound pressure levels hearing loss, described in the literature as permanent threshold shift resulting from overexposure to noise, the sensorineural type, usually bilateral and symmetrical, irreversible 10,11,12,13,14,15,16,17 , mild and severe at low frequencies at high frequencies, with typical audiometric configuration (V-shaped notch) in the frequency range of 6000, 4000 and / or 3000 Hz, which progresses slowly at frequencies of 8000, 2000, 1000, 500 and 250 Hz and reaches its maximum level at higher frequencies, in the first 10-15 years of stable to high sound pressure level (SPL) exposure and stops its progression once exposure stops…”

“…During the 1980s, the noise was the main disease among metalworkers and affected more than 60% of category 7 , and today is still rated as the most frequent agent of occupational exposure 8-11 , being described as a major cause of sensorineural hearing loss in adults 12,13 , usually bilateral, irreversible 4,8,11,[14][15][16] , affecting the inner ear and / or auditory nerve 17 , insidiously, slowly progressive changes and producing symptoms only after several years 18 .…”

“…The search results from combining descriptors ("Auditory Evoked Potential" and "Electrophysiology" and "Bone Conduction", "Auditory Evoked Potential" and "Bone Conduction", "Auditory Evoked Potential" and "Electrophysiology", "Electrophysiology" and "Bone Conduction"), according to the data base, are shown in Table 1. brainstem of the auditory nerve; wave III, cochlear nucleus; wave IV, superior olivary complex; wave V, lateral lemniscus; wave VI, inferior colliculus; and wave VII, medial geniculate body 1,4,5 .…”

“…However, although air conducted BAEP is the most widely used in clinical practice, when bone conduction is employed, there is an additional resource to help in audiologic diagnosis, characterizing hearing loss 4,6,7 . In order to assess an individual that exhibits inconsistent or unreliable responses on pure-tone behavioral audiometry, it is recommended that BAEP be used by both air and bone conduction to obtain accurate electrophysiological thresholds 4,6 .…”
