Healed neomembrane and tympanosclerosis. (Otoscopic Clinic).This is the otoscopic view of a left ear in a patient with no complaint. Hearing is normal despite the abnormal appearance of the tympanic membrane. A large, healed perforation with the two-layered membrane is seen in the posterior half of the pars tensa. At the upper edge of the perforation, the chorda tympani passes 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 sta·pes n. pl. . Anterior to the vertical long process of the malleus malleus /mal·le·us/ (mal´e-us) [L.] the outermost of the auditory ossicles, and the one attached to the tympanic membrane; its club-shaped head articulates with the incus mal·le·us n. pl. is the pars tensa, which is involved with tympanosclerosis. Occasionally, this neomembrane can rupture during swimming or diving, and tympanoplasty tympanoplasty /tym·pa·no·plas·ty/ (tim´pah-no-plas?te) surgical reconstruction of the tympanic membrane and establishment of ossicular continuity from the tympanic membrane to the oval window. might be required. In the absence of symptoms, however, no treatment is required. From the Pulec Ear Clinic, Los Angeles (Dr. Pulec), and Gap, France (Dr. Deguine). |
