tympanic

 [tim-pan´ik]
1. bell-like; resonant. Called also tympanal and tympanitic.
2. of or pertaining to the tympanum.
tympanic membrane a thin, semitransparent membrane, nearly oval in shape, that stretches across the ear canal and separates the tympanum (middle ear) from the external acoustic meatus (outer ear); called also eardrum. It is composed of fibrous tissue, covered with skin on the outside and mucous membrane on the inside. It is constructed so that it can vibrate freely with audible sound waves that travel inward from outside. The handle of the malleus of the middle ear is attached to the center of the membrane and receives the vibrations it collects, transmitting them to the other ossicles of the middle ear (the incus and stapes), which in turn transmit the vibrations to the fluid of the inner ear.



Perforation of the tympanic membrane can cause loss of hearing, the extent depending on the size and location of the perforation. Since vibrations can still be transmitted to the inner ear by way of the bones of the skull, even nearly total destruction of the tympanic membrane does not produce total deafness. Surgical incision of the membrane (myringotomy) or insertion of ventilating tubes may be done to relieve pressure and provide for drainage in an infection of the middle ear. See also otitis media.

A recent systematic review of literature and meta-analysis of TAT thermometry found that while it is not accurate enough to replace invasive thermometry methods for core body temperature evaluation (pulmonary artery, distal esophageal, bladder, nasopharyngeal) or rectal thermometry, it is comparable to axillary and tympanic thermometry in accuracy and detection of fever (Geijer, Udumyan, Lohse, & Nilsagard, 2016).
