The cochlea and the cochlear nuclei in neonatal asphyxia by Jens G Hall Download PDF EPUB FB2
Further histopathological evidence for lesions of brainstem auditory centers was provided by an earlier study focusing on the cochlea and cochlear nuclei in neonatal asphyxia . The predominant finding in this study was loss of cells in the cochlear by: We used brainstem auditory-evoked responses and neurodevelopmental assessment to detect abnormalities and correlations between such responses and neurodevelopmental outcomes in 78 children (aged years) who survived perinatal asphyxia.
Twenty children had brainstem auditory-evoked response abnormalities, including increased threshold, reduced wave V Cited by: Under the umbrella of mental retardation, the diversity of clinical entities clearly indicates a potential multitude of causal mechanisms. Two statistics, however, provide a point of departure for the present discussion: (a) the incidence of premature births, with anoxia as a common perinatal complication, is significantly elevated in mentally retarded populations (13, 29); and (b) partial Cited by: 6.

The major pathways in the acoustic reflex arc can be divided anatomically into five general portions: 1) the middle ear, the cochlea and the afferent pathway consisting of the 8 th (auditory) cranial nerve on the side of the stimulus, 2) brainstem neurons within the cochlear nuclei, 3) for contralateral acoustic reflex measurement the.
In one study of term infants with neonatal encephalopathy and evidence of intrauterine asphyxia, fully 80% had evidence of acute lesions (within the period immediately before or during labor and delivery) consistent with hypoxic-ischemic disease, 16% had normal MRI scans, and only 4% had concomitant evidence of chronic antenatal injury (see Table ).

The study of brainstem evoked response audiometry provides an opportunity to evaluate the functional integrity of auditory pathway from inner ear to upper brainstem.
Several studies have shown that early and adequate intervention of infants with congenital hearing loss minimizes future problems with speech and language development. As fluid moves past the cochlear duct d uct (scala media), its basilar membrane oscillates at a frequency corresponding to the frequency of fluid movement.
Outer hair cells (OHCs) sit atop the basilar membrane in the Organ of Corti. Oscillation of the cochlear duct deflects their stereocilia against the tectorial membrane.

Beginning in the cochlea, the frequency specificity is maintained at each point of the central auditory pathway: dorsal and ventral cochlear nuclei, trapezoid body, superior olivary complex, lateral lemniscus, inferior colliculus, medial geniculate body, and auditory cortex.
Cochlea The cochlear duct, the auditory portion of the labyrinth, extends approximately 35 mm.9 The cochlear duct and associated sensory and supportive structures assume the form of a spiral similar to a snail shell of 21⁄2 to 23⁄4 turns (Figure 1–9).
This allows the long cochlear duct to be contained in a small space. Full text of "Otolaryngology Basic Science And Clinical Review" See other formats.
