A preauricular sinus is a common congenital malformation characterized by a nodule, dent or dimple located anywhere adjacent to the external ear. Frequency of preauricular sinus differs depending the population: 0.1–0.9% in the US, 0.9% in the UK, and 4–10% in Asia and parts of Africa.

[Article in Chinese] Hua N, Wei L, Jiang T, Guo Y, Wang M, Wang Z. OBJECTIVE: To investigate the pathology characteristics of congenital preauricular fistula with infection, in order to reduce the recurrence rate after surgery and improve operative technique. Publicationdate January 21, 2009. Perianal fistula is a common disorder that often recurs because of infection that was missed at surgery.
RESULTS: Sonography detected the sinus in all cases. The maximum width of the sinus tract was 3 mm; it showed a branching pattern in four (27%) patients. Preauricular cysts, pits (as shown below), fissures, and sinuses are benign congenital malformations of the preauricular soft tissues first described by Van Heusinger in 1864. Preauricular pits or Color-Doppler Flow Imaging (CDFI) demonstrated continuity with the main trunk of superficial temporal artery (STA) and displayed a turbulent flow inside the lesion. A computed tomography (CT) angiography was also performed, confirming that the preauricular mass was a saccular aneurysm of the main trunk of STA, measuring 1.4 cm in diameter. Preauricular pits and sinuses – these are common, affecting 1% of the population, particularly Asians and blacks.
A preauricular sinus tract is probed with a blunt needle, and methylene blue dye is injected.
Preauricular fistula: usually on the top of the cristae helicis of the ears; I: Diseases of the circulatory system (I25.4) Coronary arteriovenous fistula, acquired (I28.0) Arteriovenous fistula of pulmonary vessels. Pulmonary arteriovenous fistula: between an artery and vein of the lungs, resulting in shunting of blood. The cheek fistulae were accompanied by ipsilateral preauricular appendages in all seven patients.
A congenital subcutaneous fistula/sinus, also known as a dermal fistula/sinus, is a fairly common pediatric condition that can occur in various locations. 1, 2 As radiology is a discipline that encompasses numerous specialties; radiologists and sonographers often examine children with various diseases referred by different departments. Thus, it is important for radiologists to be familiar with

A pit is essentially a sinus tract traveling under the skin that doesn’t belong there; it’s marked by a tiny opening to the tract, right in front of the ear and above the ear canal. In atypical cases, the opening appears below the ear canal, closer to the lobe. Radiology Department of the Medical Centre Alkmaar and the Rijnland hospital, Leiderdorp, the Netherlands.

A preauricular cyst should not be confused with a 1st branchial cleft remnant. Misdiag- nosing a 1st brachial cleft remnant as a pre-auricular sinus tract may place the facial nerve at risk, and incompletely excising the sinus tract.

The preauricular sinus is a blind canal, positioned mostly in front of the tragus and the helix, and extends from the epidermis to subcutaneous tissues, being one of the frequently seen congenital ear anomalies (2). The etiology of preauricular sinuses and fistulas are not completely discovered, yet, they are thought of as

Iatrogenic (hemorrhoideal surgery) A congenital pit or sinus involving the ascending limb of the helix of the ear (fig. 1 a) or the preauricular region is of little importance unless it gives rise to an offensive discharge or forms a retention cyst (fig. 1 b).
