Congenital neck masses are swellings that appear when certain structures, which should disappear during development in the womb, persist after birth. Although they are usually noticed in childhood, some first cause symptoms in adolescence or young adulthood. Most are benign, but because they are prone to infection and do not go away on their own, they often require planned surgical treatment.<\/p>\n
In the womb, the neck and face form from arch-shaped structures called the “pharyngeal arches.” The thyroid gland also forms at the base of the tongue and descends along a thin duct to the front of the neck. These temporary structures and ducts normally disappear; a persisting remnant may remain as a cyst (a fluid-filled sac), a sinus (a blind-ended channel opening onto the skin) or a fistula (an open channel connecting two surfaces).<\/p>\n
A neck lump is a common reason children are brought for an ear, nose and throat (ENT) examination. Most such lumps are lymph nodes enlarged by infection; congenital masses come second. Telling them apart matters: an infected congenital cyst can look very much like an enlarged lymph node.<\/p>\n
Location is an important clue, since midline and side-of-neck masses usually have different origins:<\/p>\n
The cause is a small disruption in embryonic development. It is not linked to anything the mother did during pregnancy, and usually no specific reason is found. The main types are:<\/p>\n
This is the most common congenital neck mass in children. It develops from a remnant of the duct the thyroid follows as it descends from the tongue base. It usually sits in the front midline of the neck, at the level of the hyoid bone (the small U-shaped bone above the larynx). Because the duct is closely linked to the hyoid bone, the cyst moves upward when the child swallows or sticks out the tongue, an important clue during examination.<\/p>\n
These develop from remnants of the pharyngeal arch structures and appear on the side of the neck. The most common type is the second branchial cleft cyst, located along the front edge of the large neck muscle that runs from below the ear to the collarbone (the sternocleidomastoid muscle). First cleft anomalies occur around the ear, close to the parotid salivary gland; third and fourth cleft anomalies are seen mainly in the lower left neck and may present as recurrent inflammation of the thyroid.<\/p>\n
Formerly called cystic hygroma<\/em>, this is a developmental abnormality of the lymph vessels. Most are noticed at birth or become apparent before age two. It appears as a soft, nontender mass that feels fluid-filled under the skin. Depending on the size of the sacs inside, it is classified as macrocystic or microcystic. Large ones can, rarely, affect the airway and swallowing.<\/p>\n This forms when cells that make up skin and skin structures become trapped in deeper tissues during development. It is usually located under the chin in the midline; unlike a thyroglossal duct cyst, it does not move with the tongue. It grows slowly and contains a thick, cheesy material.<\/p>\n Vascular tumors such as hemangiomas in infants, thymic cysts and a firm thickening of a neck muscle in newborns (fibromatosis colli) can also be counted among birth-related neck swellings. Some of these are treated without surgery.<\/p>\n Often the only symptom is a soft, round neck swelling. It may go unnoticed for years and draw attention when it suddenly enlarges after a cold or throat infection. Common symptoms include:<\/p>\n During infections, the cyst can become painful and red, sometimes with fever. Even if the swelling shrinks once the infection clears, the cyst remains and tends to flare up again with new infections.<\/p>\n The age at which these masses are noticed varies by type. Lymphatic malformations are sometimes seen on prenatal ultrasound, and most often at birth or within the first two years. Thyroglossal duct cysts frequently come to attention in preschool and school-age children after an infection. Branchial cleft cysts may become apparent later, in adolescence and young adulthood. So “congenital” does not mean the mass will always be visible at birth; it means its origin lies in development before birth.<\/p>\n The first step is a detailed history (when the swelling appeared, whether it grows with infections, any drainage) and a physical examination. The location and consistency of the mass, and whether it moves with swallowing and tongue movement, are assessed. The mouth, throat and larynx may also be examined endoscopically.<\/p>\n Rarely, a mass thought to be a thyroglossal duct cyst turns out to be thyroid tissue that never descended and is the only functioning thyroid. Confirming the location of the thyroid before surgery is therefore an important safety step.<\/p>\n In adults, a cystic mass on the side of the neck is not always a branchial cleft cyst. Especially in people over forty, spread of a tumor from areas such as the tonsils or base of the tongue to a lymph node can also look cystic. For this reason, adults receive a thorough ENT examination and, if needed, an ultrasound-guided fine-needle aspiration biopsy to obtain a cell sample from the mass.<\/p>\n Congenital cysts do not disappear on their own and are prone to repeated infections. For most patients, definitive treatment is therefore surgical removal of the cyst together with any associated duct. The operation is performed under general anesthesia and usually takes 2-3 hours.<\/p>\n When a cyst becomes infected, antibiotics are given first, and the abscess is drained if necessary. Surgery is planned once the inflammation has fully settled, usually after waiting a few weeks. Operating during an active infection makes the tissues harder to separate and may increase the risk of recurrence, so a planned operation during a calm period, ideally before infection occurs, is preferred.<\/p>\n Before surgery, the child’s overall health is assessed, blood tests are done and the anesthesia evaluation is completed. Families receive written fasting instructions. Explaining what will happen in a calm, honest way suited to the child’s age reduces anxiety on the day of surgery. A recent fever or cough should always be reported, as surgery may need to be postponed.<\/p>\n Patients usually stay in the hospital for 1 day of observation. In some cases, a thin drain is used to remove any fluid that collects, and it is taken out shortly afterward. Children usually start eating and drinking by mouth the same day. Returning to school and social life is generally possible within 1 week; waiting a few weeks before contact sports is recommended. Because the incision is planned along the natural lines of the neck, the scar fades over time.<\/p>\n Families traveling to Istanbul should generally plan to stay about a week after surgery. This allows for the hospital stay, drain removal if a drain was placed, and the first wound check. Flying is often considered reasonable after about a week if healing is going well, but your surgeon will advise on timing for your child. The pathology result and later follow-up can be coordinated remotely. Bringing previous ultrasound or scan reports and images, and a medication list, makes the first visit more efficient.<\/p>\n Surgery for congenital cysts is generally safe in experienced hands, but as with any operation, some risks exist:<\/p>\n Families should not try to squeeze or drain a red, rapidly growing or draining neck swelling themselves, for example with a needle. After surgery, seek medical attention without delay for high fever, redness or discharge at the wound, rapidly increasing swelling or difficulty breathing.<\/p>\n Congenital cysts such as thyroglossal duct cysts, branchial cleft cysts and dermoid cysts do not disappear on their own. If they swell during an infection and then shrink, that does not mean the cyst is gone. A small proportion of lymphatic malformations, however, may regress spontaneously.<\/p>\n There is no strict age limit. The decision depends on the type and size of the cyst, whether it has been infected and the child’s overall health. For cysts prone to infection, surgery during a calm period, before inflammation recurs, is generally preferred.<\/p>\n No. In children, the most common cause of neck masses is lymph node enlargement due to infection. In adults, a newly noticed neck mass is investigated more thoroughly for other causes. Examination and ultrasound are needed to make this distinction.<\/p>\n When the cyst and its duct are removed completely, the chance of recurrence is low. For thyroglossal duct cysts, the Sistrunk procedure significantly reduces the risk. In cysts that have had many infections, the chance of recurrence is somewhat higher.<\/p>\n Yes. Branchial cleft cysts in particular are often noticed in adolescence or young adulthood, when they enlarge after a throat infection. In adults, cystic masses on the side of the neck are carefully evaluated to rule out other causes.<\/p>\n Op. Dr. Tayfun Demirel, an ENT specialist, evaluates children and adults with neck masses at the practice in Ata\u015fehir, Istanbul, using examination and tests such as ultrasound. Depending on the type and size of the mass and its history of infection, the decision between follow-up and surgery, as well as the timing of the operation, is planned individually.
