Newborn hearing screening at Rajavithi Hospital, Thailand: hearing loss in infants not admitting in intensive care unit.

Background: Approximately one to two per 1000 newborns have hearing loss. Delay in detection of this disability leads to impaired development and may prevent the acquisition of speech. Early screening of hearing in newborns results in children receiving early language rehabilitation.

Effects of insertion depth of cochlear implant electrodes upon speech perception.

Objective: To investigate whether the insertion depth of a cochlear implant array affects postoperative speech perception.

Design: The subjects were 48 postlingually deaf adults who received either the Nucleus 22 or the Nucleus 24 cochlear implant with a straight array. A postoperative radiograph of the cochlear electrode was used to estimate insertion depth, as either the angle of the electrode tip (angle) or the intracochlear length of the electrode (length).
