In anatomy, a fistula ( pl.: fistulas or fistulae /- li, - laɪ /; from Latin fistula, "tube, pipe") is an abnormal connection (i.e. tube) joining two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs to each other, often resulting in an abnormal flow of fluid from one space to ...

Long standing buccal abscesses tend to spontaneously drain via a cutaneous sinus at the inferior of the space, near the inferior border of the mandible and the angle of the mouth. [1] An untreated cutaneous sinus can cause disfiguring soft tissue fibrosis, and the tract can become epithelial lined. [3]
The parotid gland is a major salivary gland in many animals. In humans, the two parotid glands are present on either side of the mouth and in front of both ears. They are the largest of the salivary glands. Each parotid is wrapped around the mandibular ramus, and secretes serous saliva through the parotid duct into the mouth, to facilitate mastication and swallowing and to begin the digestion ...
Salivary gland diseases ( SGDs) are multiple and varied in cause. [1] There are three paired major salivary glands in humans: the parotid glands, the submandibular glands, and the sublingual glands. There are also about 800–1,000 minor salivary glands in the mucosa of the mouth. The parotid glands are in front of the ears, one on side, and secrete mostly serous saliva, via the parotid ducts ...
Fistulectomy is a surgical procedure where a surgeon completely removes a fistula, an abnormal tract (i.e. tube) that connects two hollow spaces of the body. [1] [2] In comparison to other procedural options of treating fistulae such as fistulotomies, where a fistula is cut open (i.e. unroofed) but not completely removed, and seton placement ...
Anal fistulae commonly occur in people with a history of anal abscesses. They can form when anal abscesses do not heal properly. [3] Anal fistulae originate from the anal glands, which are located between the internal and external anal sphincter and drain into the anal canal. [4]
