Ny!!: Asymtomatisk och Medfödd aurikulär fistel · Se mer » Naturlig reservoa Post-aurikulär Preauricular sinuses (also known as preauricular pits or preauricular cysts) are common congenital abnormalities that are typically small blind-ended openings near the ascending limb of the helix.

Objective: To determine the histologic relationship and distance between excised preauricular epithelial sinus tract and the adjacent auricular cartilage (sinocartilaginous distance) in a series of patients. The excision of preauricular sinuses is a common surgical procedure. Recurrences are frequent and can be technically challenging. First branchial cleft: preauricular area (type I cyst) or below the angle of mandible (type II), may be connected to external auditory canal; cysts are rarely malignant (Diagn Cytopathol 2008;36:876); 5% - 8% Second branchial cleft: anterior to sternocleidomastoid muscle in midneck, may communicate with pharynx; 95% (Singapore Med J 2015;56:203) Infected preauricular cyst with swelling and erythema toward the cartilage of the ear. A preauricular sinus tract is probed with a blunt needle, and methylene blue dye is injected.
