Video Summary

Dr. Ted Venema, a professor at Conestoga College, gave a presentation on tympanometry and its importance in understanding the middle ear. Tympanometry is a quick and non-invasive test that measures the compliance of the middle ear and can help determine the type of hearing loss a person may have. The test involves changing the air pressure in the ear canal and measuring the amount of sound that bounces back off the eardrum. Different types of tympanograms can indicate different pathologies, such as otitis media or otosclerosis. The presentation also touched on the role of acoustic reflexes and how they can affect tympanometry. The acoustic reflexes involve the stapedius muscle in the middle ear and can reduce sound by about 5-15 dB. The presentation concluded by discussing the acceptable level of cerumen in the ear canal for accurate tympanometry testing. Overall, tympanometry is a valuable tool for clinicians in understanding the functioning of the middle ear and diagnosing various conditions.
