One of the causes of conductive hearing loss is:
A) Sudden loud noise
B) Ototoxic medication
C) Auditory nerve damage
D) Excess middle ear fluid
Ans: D
Feedback:
Conductive hearing loss occurs when auditory stimuli are not adequately transmitted through the auditory canal, tympanic membrane, middle ear, or ossicle chain to the inner ear; it is usually the result of middle ear fluid or infections. Other causes include ear canal cerumen, or foreign bodies, tympanic membrane thickening or damage, or bony structure (ossicles and oval window) damage of the middle ear caused by otosclerosis or Paget disease. Sensorineural deafness occurs when sound waves are conducted to the inner ear but abnormalities of the cochlear apparatus or auditory nerve decrease or distort the transfer of information to the brain. Causes of sensorineural deafness include genetic, infectious, traumatic loud noises, and ototoxic factors.
