Erythema (Ancient Greek: ἐρύθημα, from Greek erythros 'red') is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. [1] It occurs with any skin injury, infection, or inflammation .
Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position.. The eardrum comprises two parts: the pars tensa, which is the main part of the eardrum, and the pars flaccida, which is a smaller part of the eardrum located above the pars tensa.
The outer ear is the external portion of the ear and includes the fleshy visible auricle, the ear canal, and the outer layer of the eardrum (also called the tympanic membrane). [ 2 ] [ 3 ] The auricle consists of the curving outer rim called the helix , the inner curved rim called the antihelix , and opens into the ear canal.
Erythema multiforme (EM) is a skin condition that appears with red patches evolving into target lesions, typically on both hands. [2] [3]It is a type of erythema possibly mediated by deposition of immune complexes (mostly IgM-bound complexes) in the superficial microvasculature of the skin and oral mucous membrane that usually follows an infection or drug exposure.
Chondrodermatitis nodularis chronica helicis (CNCH) is a small, nodular, tender, chronic inflammatory lesion occurring on the helix of the ear, most often in men. [ 2 ] : 610 it often presents as a benign painful erythematous nodule fixed to the cartilage of the helix or antihelix of the external ear. [ 3 ]
This left cheek incision extends from the left commissure towards the left ear and it breaches the vermilion border (click to see close-up). In order to maintain aesthetics as best possible, the first suture was placed at or near the vermilion border to ensure a contiguous line upon healing.
Mastoiditis is the result of an infection that extends to the air cells of the skull behind the ear. Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside [1] the mastoid process. The mastoid process is the portion of the temporal bone of the skull that is behind
Autoimmune inner ear disease (AIED) was first defined by Dr. Brian McCabe in a landmark paper describing an autoimmune loss of hearing. [2] The disease results in progressive sensorineural hearing loss (SNHL) that acts bilaterally and asymmetrically, and sometimes affects an individual's vestibular system .
