What is branchial cleft fistula?
What is branchial cleft fistula?
Branchial cleft fistulae are rare congenital abnormalities that arise from the abnormal persistence of branchial apparatus remnants. A complete fistula is a tract that has an internal opening and an external opening.
How is branchial fistula developed?
The branchial fistula results from breakdown of the endoderm, usually in the second pouch.
What causes branchial cleft sinus?
What are the causes? Branchial cleft cysts and sinus tracts are congenital anomalies, meaning they result from an unexpected change in the womb before birth. Although most commonly unilateral (occurring on one side of the neck), they can be bilateral (both sides of the neck).
How does a branchial cleft cyst form?
Branchial cleft cysts form during development of the embryo. They occur when tissues in the neck and collarbone area (branchial cleft) fail to develop normally. The birth defect may appear as open spaces called cleft sinuses, which may develop on one or both sides of the neck.
What is sinus and fistula?
A fistula is an abnormal passage between a hollow organ and the skin surface, or between two hollow organs¹. “A wound sinus is a discharging blind-ended tract that extends from the surface of an organ to an underlying area or abscess cavity”. The cause of a sinus must always be determined by in-depth assessment.
What is Branchial sinus?
A branchial cleft is also called a cleft sinus. It is a lump or cyst that develops in your neck or near your collarbone. It develops in the womb before birth and is usually diagnosed shortly after birth.
What is a fistula in the neck?
A fistula is an abnormal channel leading between two cavities or surfaces which may drain a fluid material such as saliva or pus. An example would be from the mouth (oral cavity) to the skin surface, usually of the face or neck, and this specific type is called an orocutaneous fistula.
How rare is a branchial cleft fistula?
Complete branchial fistulas are extremely uncommon with only very few reported cases in literature. [1] Demonstration of such complete fistulas by fistulogram is considered rare. [2] The branchial fistula arising from each arch can be identified from the position of the internal and external openings.
What is branchial sinus?
How does fistula develop?
Fistulas form when inflammation causes sores, or ulcers, to form on the inside wall of the intestine or nearby organs. Those ulcers can extend through the entire thickness of the bowel wall, creating a tunnel to drain the pus from the infected area. An abcess, or a collection of pus, can also cause a fistula to form.
What is sinus tract formation?
A tunneling wound or sinus tract is a narrow opening or passageway extending from a wound underneath the skin in any direction through soft tissue and results in dead space with potential for abscess formation.
What is sinus fistula?
A carotid-cavernous sinus fistula (CCF) is an abnormal connection between an artery in your neck and the network of veins at the back of your eye. These veins at the back of your eye transport blood from your face and brain back to your heart and are located in small spaces behind your eyes called cavernous sinuses.
