Document Summary

This is important because it tells audiologists what to expect and it gives them a starting point: describe otoscopy and the instrument used to perform it: examines the structures of the pinna, eam, and tympanic membrane. And otoscope is used to examine these structures. Air testing: use an audiometer, pure tones presented through headphones; it tests the entire peripheral system, if hearing loss is identified than you cannot localize where the hearing loss is coming from. Conductive hearing loss: air conduction is worse than the bone conduction; likely caused by ear wax blockage or other type of blockage ; bone is in normal range. Sensorineural hearing loss: the air = the bone gap, there is a loss in the bone testing. Mixed hearing loss: there is a loss in air and bone but air is worse than bone. Outer ear: pinna, tympanic membrane, cone of light. Middle ear: ossicles ( malleus, incus, stapes), middle ear muscles acoustic reflex,
