tympanometry & pneumatoscopy

[leseanne]

could someone please tell me the difference between tympanometry and pneumatoscopy, its not in my med-surg book & when i google pneumatoscopy i cannot get any results that explain it.

pneumatoscopy:

application of air into the ear canal during observation

Tympanometry is an examination used to test the condition of the middle ear and mobility of the eardrum (tympanic membrane) and the conduction bones by creating variations of air pressure in the ear canal.

the best I can figure is that pneumatoscopy applies constant pressure and Tympanometry applies variable pressure.

thank you so much.
