Progressive conductive hearing impairment
Not progressive but can occur acutely or chronically
Tympanic membrane laceration
Tear to the eardrum, may be accute
Speech recogniton threshold
Measured in decibles and corresponds to the intensity level at which spondiac words can be recognized approximately 50% of the time
Exceedingly high amplitude tympanogram
Ossicular chain disruption results in a high admittance, which will cause a high amplitude tympanogram. Another cause of a high amplitude tympanogram could be a hypermobile eardrum.
