|
cochlear implant
|
Surgical implanted device allowing sensorineural hearing-impaired persons to understand speech. Electrical signals are sent directly into the auditory nerve by means of multiple electrodes inserted into the cochlea. An external microphone and speech processor pick up sound signals and convert them to electrical impulses

otoscopy
|
Visual examination of the ear with an otoscope.

|
tuning fork test
|
Test of ear conduction using a vibration source (tuning fork). To perform (Rinne test), the examiner places the base of the vibrating fork against the patient's mastoid bone (bone conduction) and in front of the auditory meatus (air conduction). In the Weber test, the tuning fork is placed on the center of the forehead. The loudness of sound is equal in both ears if hearing is normal.

ear thermometry
|
