Preauricular pits and sinuses – these are common, affecting 1% of the population, particularly Asians and blacks. 25% are bilateral in front of both ears. The sinus opening ( pit ) is usually located just in front of the upper part of the ear where the cartilage of the ear rim (helix) meets the facial skin.
the preauricular sinus with a low recurrence rate. In this study, we present our experiences in the management of preauricular sinuses, based on a new surgical classification of preauricular sinuses. We investigated the proper timing of surgery, the resection range, and potential surgical cautions. Materials and methods Study design
The causes of perianal fistulas: Primary. Obstruction of anal gland which leads to stasis and infection with absces and fistula formation (most common cause). Secondary. Iatrogenic (hemorrhoideal surgery) A congenital pit or sinus involving the ascending limb of the helix of the ear (fig.

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. Preoperative MR can help to prevent recurrence. In this review we will address the anatomy, pathogenesis, classification and scanning protocol of perianal fistulas. by Susanne Tonino and Robin Smithuis.

Abstract: Congenital preauricular fistula is a blind tract lined by squamous epithelium starting in front of the auricle. It is due to faulty fusion of the first arch tubercle to other tubercles. If no symptoms are present it requires no treatment.
Thyroglossal duct cyst – the most common developmental cyst in the neck. The cyst characteristically moves upwards when the tongue is poked out or with swallowing. It may burst to form a sinus which usually opens just below the hyoid bone in the midline of the neck.

A preauricular sinus tract is probed with a blunt needle, and methylene blue dye is injected.
preauricular sinus was observed in front of the right ear of an 18-year-old male patient with a recurrent swelling and wound infection for 3 years; and the case was discussed in the guidance of the literature.

Perianal fistula (or fistula-in-ano) (plural: fistulae or fistulas) is the presence of a fistulous tract across/between/adjacent to the anal sphincters and is usually an inflammatory condition 4. Epidemiology Incidence is estimated at ~1:10,000
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. These can be a simple pit or have a sinus tract and/or cystic component.
