The most Common site of perilymph fistula
Correct Answer: both 1 and 2
Description: Perilymph fistula: In this condition, perilymph leaks into the middle ear through the oval or round window.
It can follow as a complication of stapedectomy or ear surgery when stapes is accidentally dislocated.
It can also result from sudden pressure changes in the middle ear (e.g. barotrauma, diving, forceful Valsalva) or raised intracranial pressure (weightlifting or vigorous coughing). A perilymph fistula causes intermittent vertigo and fluctuating sensorineural hearing loss, sometimes with tinnitus and sense of fullness in the ear (compare Ménière’s disease).
