Tympanic membrane atelectasis.A 42-year-old woman presented with bilateral chronic otitis media Chronic otitis media Inflammation of the middle ear with signs of infection lasting three months or longer. Mentioned in: Myringotomy and Ear Tubes chronic otitis media that had been present since childhood. She had previously undergone two surgeries for left cholesteatoma, and her left ear was well healed. She also complained of bilateral hearing loss, but she denied otalgia otalgia /otal·gia/ (o-tal´jah) pain in the ear; earache. o·tal·gia n. Pain in the ear; earache. o·tal and otorrhea. Otoscopic examination of the right ear revealed an atelectatic tympanic membrane with myringostapediopexy (figure). The head of the malleus was visible through the pars flaccida retraction. The ossicles Ossicles The three small bones of the middle ear: the malleus (hammer), the incus (anvil) and the stapes (stirrup). These bones help carry sound from the eardrum to the inner ear. Mentioned in: Otitis Media, Stapedectomy appeared to be intact. Pneumatic otoscopy demonstrated fixation of the tympanic membrane to the promontory. The patient had a 15-dB airbone gap and a type C tympanogram on the right. [FIGURE OMITTED] J. Walter Kutz Jr., MD; Jose N. Fayad, MD Chronic eustachian tube dysfunction often causes tympanic membrane retraction and atelectasis atelectasis or lung collapse Lack of expansion of pulmonary alveoli (see pulmonary alveolus). With a large-enough collapsed area, the victim stops breathing. . If the process continues to evolve, a cholesteatoma may form. A conductive hearing loss Conductive hearing loss A type of medically treatable hearing loss in which the inner ear is usually normal, but there are specific problems in the middle or outer ears that prevent sound from getting to the inner ear in a normal way. may develop through ossicular erosion or cholesteatoma information. |
