Branchial Cleft Cyst: Causes, Symptoms, Diagnosis, Treatment, and Prevention
A branchial cleft cyst is a type of birth defect that occurs when some tissues in the neck and face do not develop properly during the fetal stage. These tissues form abnormal openings or sacs on one or both sides of the neck, which can fill with fluid or drain through the skin. It is possible that a branchial cleft cyst does not cause symptoms until it becomes infected or enlarged, which can affect the breathing and swallowing of the affected individual.
Causes of Branchial Cleft Cyst
In the embryonic development process, the branchial arches fail to shrink or disappear, resulting in a branchial cleft cyst. Branches are five bands of tissue that form the bones, muscles, blood vessels, and cartilage in the neck, face, and upper chest. Four clefts, depressions on the surface of the embryo, normally separate the branchial arches. By the seventh week of pregnancy, these clefts are buried and shrink, leaving only the first cleft as an external ear canal. If the clefts do not completely shrink or disappear, they may develop branchial cleft anomalies, such as cysts, sinuses, or fistulas.
Symptoms of Branchial Cleft Cyst
Although branchial cleft cysts are present at birth, they may not appear until later in life. Symptoms of branchial cleft cysts vary depending on the type and location of the anomaly, as well as the presence of infection or inflammation. Common symptoms include:
-
A lump, dimple, or skin tag on the neck, upper shoulder, or below the collarbone
-
Fluid draining from an opening on the neck
-
Swelling or tenderness in the neck, especially during an upper respiratory infection
-
Difficulty swallowing or breathing
-
Pain or discomfort in the ear or jaw
Diagnosis of Branchial Cleft Cyst
When a doctor examines the patient, he or she may feel the lump or see the opening in the neck. In addition to asking about the patient's medical history, the doctor may order some tests to confirm the diagnosis and rule out other possible causes, including:
-
This noninvasive test uses sound waves to create images of the internal structures of the neck. It can determine the size, shape, location, and presence of fluid or infection within the branchial cleft cyst.
-
The CT scan can provide more information about the extent and depth of the branchial cleft cyst, as well as the involvement of other tissues or organs.
-
A magnetic resonance imaging scan shows the anatomy and function of the branchial cleft cyst, as well as the blood flow and nerve activity around the cyst.
Treatment of Branchial Cleft Cyst
A branchial cleft cyst's treatment depends on the symptomatology and complications of the patient, as well as the type, size, and location of the anomaly. Several possible treatment options include preventing infection, relieving symptoms, and removing abnormal tissue.
-
They are usually prescribed for a course of seven to ten days, or until the infection has cleared up. Antibiotics can help fight bacterial infections that may occur in the branchial cleft cysts or sinuses.
-
In order to treat branchial cleft cysts, surgery involves removing the entire cyst, sinus, or fistula, along with the surrounding tissues. For persistent or recurrent infections, large or symptomatic cysts, or cosmetic reasons, surgery is usually recommended. To minimize scarring, the incision is usually placed along the natural creases of the neck during the surgery. Depending on the complexity and extent of surgery, recovery time and complications may vary.
-
It is an option for small or asymptomatic branchial cleft cysts that do not interfere with the neck's normal function. A doctor may advise the patient to report any changes or signs of infection to him or her. In young children with higher risks of surgical complications or anesthesia reactions, observation may be preferred.
Prevention of Branchial Cleft Cyst
Branchial cleft cysts are not preventable, as they are congenital anomalies that occur during the early stages of fetal development. However, some factors that may increase the risk of birth defects in general include:
-
Genetic or chromosomal abnormalities
-
Maternal infections or illnesses
-
Exposure to harmful substances or radiation
-
Medications or drugs
-
Nutritional deficiencies or excesses
Therefore, to reduce the risk of birth defects, it is important for pregnant women to:
-
Take prenatal vitamins and folic acid supplements
-
Eat a balanced and healthy diet
-
Avoid alcohol, tobacco, and recreational drugs
-
Consult with the doctor before taking any medications or herbal remedies
-
Get regular check-ups and screenings
-
Avoid contact with sick people or animals
-
Avoid exposure to chemicals, pollutants, or radiation
Summary
When some tissues in the neck and face do not develop properly during the fetal stage, the branchial cleft cyst develops. It is possible for these tissues to form abnormal openings or sacs on either side of the neck, which can fill with fluid or drain through the skin. A branchial cleft cyst may not cause any symptoms until it becomes infected or enlarged, which can affect the breathing and swallowing of the affected person. An ultrasound, CT scan, or MRI scan is usually used to diagnose branchial cleft cysts. It is important to note that the treatment of branchial cleft cysts depends on the type, size, and location of the anomaly as well as the symptoms and complications experienced by the patient. Treatment options include antibiotics, surgery, or observation to prevent infection, relieve symptoms, and remove abnormal tissue. Despite the fact that brachial cleft cysts cannot be prevented, certain factors may increase the risk of birth defects in general, including genetic or chromosomal abnormalities, maternal infections or illnesses, exposure to radiation or harmful substances, medications or drugs, and nutritional deficiencies or excesses. It is important for pregnant women to take prenatal vitamins and folic acid supplements, eat a balanced and healthy diet, avoid alcohol, tobacco, and recreational drugs, consult with their doctor before taking any medications or herbal remedies, get regular checkups and screenings, avoid contact with sick people or animals, and stay away from chemicals, pollutants, and radiation to reduce their risk of birth defects.
