tympan(o)-

The eardrum.

[Greek tumpanon, drum.]

The formal name for the eardrum is tympanum; medical terms that refer to it include tympanoplasty, surgical repair of defects of the eardrum or the ossicles of the middle ear; tympanometry, the measurement, for diagnostic purposes, of changes in the compliance of the tympanic membrane as the air pressure is altered in the passage of the external ear, leading to the production of a tympanogram, a graphical record of the pressure changes; tympanosclerosis is thickening of the tympanic membrane, and of the connective tissue in the tympanic cavity. However, the condition called tympanides is swelling of the abdomen with air or gas so that it becomes resonant or drumlike. The timpani or tympani are the kettledrums, especially when played by one musician in an orchestra.
