Audiology Disorders Flashcards
Microtia
part of the pinna is missing or deformed (outer ear disorder)
Anotia
complete absence of pinna, common in individuals with Down Syndrome (auricle disorder)
Otoplasty/pinnaplastry
procedure done to repair the pinna, just for appearance
Basal Cell carcinoma
most common form of skin cancer, result of too much ultraviolet light from the sun (auricle disorder)
Keloids
can be removed but may grow back, scar tissue development and it swells (auricle disorder)
Tumour
painless, slowly growing solid tumour that distorts the auricle and destroys the normal architecture (auricle disorder)
Cauliflower ear
caused from repeated blows to the ear, fluid and blood fill the space and harden, causing permanent deformity (auricle disorder)
Perichondritis of the auricle
complication of an ear-piercing, looks ready to burst, skin is red and warm
Auricular hematomas
caused by direct trauma to the pinna, torn perichondria vessel bleed between the detached perichondrium and underlying cartilage
Psoirasis of the external ear
itchy, flakey skin inside the ear (auricle disorder)
Bifid earlobe
earlobe is divided into two small sections (auricle disorder)
Supernumerary auricle
it does not affect hearing, just doesn’t look ecstatically
appealing (auricle disorder)
Cerumen
causes a conductive hearing loss, affects localization of sound, loss of approximately 45dB for conductive hearing loss (EAC disorder)
Stenosis
narrowing of the body Canal (EAC disorder)
Atresia
complete blockage of the canal, loss of 60dB of hearing, this is when bone conduction picks up (EAC disorder)
Otomycosis
fungal ear infection (EAC disorder)
