Tympanosclerosis (cosmetic) and retraction. (Otoscopic Clinic).The otoscopic view is that of a right ear in an asymptomatic patient. A large area of tympanoscierosis involves the anterior and inferior portions of the pars tensa. This is cosmetic and is not producing fixation of the tympanic membrane or the ossicular chain. There is slight retraction over the incus incus /in·cus/ (ing´kus) [L.] the middle of the three ossicles of the ear, which, with the stapes and malleus, serves to conduct vibrations from the tympanic membrane to the inner ear. Called also mal·le·us n. pl. is also slightly retracted. At the posterior annulus and external auditory canal external auditory canal n. See ear canal. , an accumulation of cerumen cerumen /ce·ru·men/ (se-roo´men) earwax; the waxlike substance found within the external meatus of the ear.ceru´minalceru´minous ce·ru·men n. is present. Although this ear should have regular, routine observation to detect any progression of the retraction of the pars tensa, it is probably stable and will require no treatment.
