At the bottom of the ear canal is the tympanic membrane which establishes the border between the external and middle ear.. Auricle The auricle, also known as pinna, is a wrinkly musculocutaneous tissue that is attached to the skull and it functions to capture sound. Examination of the right ear revealed a dull and retracted tympanic membrane. Here the eardrum is bulging, and most landmarks are obscured.

A thickened, retracted tympanic membrane and an increased attenuation of the tympanic cavity and mastoid cells can be observed on multidetector computed tomography (MDCT) images (Fig. Collagen types I and III were found in the edematous connective tissue around the main collagen layer and around dilated blood vessels. Upon completion of the procedure, all or a portion . Along with increased mucus production, there is dilatation of mucosal blood vessels, which brings white blood cells and antibodies to the area, all of which contribute to the mucopurulent defensive barrier. Viscous bubbles may also be seen behind the tympanic membrane, particularly during . Approximate Synonyms. The ossicles may become eroded, with the development of a conductive hearing loss.
