Cysts are lumps found on human body with an outer cover of skin and some fluid inside it. Cysts are normally asymptotic and are found out on routine examination for the diagnosis of other diseases. Cysts found on the throats are known as throat cysts. Common symptoms of cysts on throats are difficulties experienced while swallowing food or while breathing. A cyst may grow in size and exert pressure on tissues surrounding it. Rarely there is a possibility of the tissues becoming cancerous.
Human neck contains a number of lymphatic tissues in and around it. Examples are tissues under the chin, tonsils etc. When throat is infected these lymph cells swells and caused a throat cyst.
Dermoid cyst: This cyst will be present in a person from his birth itself. As the person grows this cyst also grows in size.
Epidermoid cyst: Any cyst in the neck can normally be epidermoid cyst. Outer cells of the cysts are replaced by newer cells in due course of time. Sometimes this outer cell which has to be replaced moves inside and multiplies to form clusters thereby enlarging the cyst. This cyst may secrete a yellow pasty substance which drains from the cyst.
Shwannomas: Nerve fibers are covered by shwann cells. These cells may grow abnormally forming clusters leading to Shwannomas. Nerves found in the head and neck region has every possibility of forming shwannomas.
Swelling of salivary glands: Major salivary gland found inside the mouth may get infected causing swelling in them. This may lead to cysts if they are not getting proper medical care.
Sebaceous cyst: Blocking of sebaceous gland in the skin may cause the formation of cysts. The cysts found in the throat and neck can be sebaceous in nature.
Thyroglossal duct cysts: Thyroglossal duct is a duct form foramen cecum to the thyroid gland. Cysts found in this duct are known as thyroglossal duct cysts. These cysts can cause infection and swelling to the throat.
Removal of throat cysts
Throat cysts may grow in size which causes them to press the nearby structures. Frequent infection and possibility of the cysts bursting are other complications that may arise. A surgical procedure named thyroglossal cyst removal is the common method used by ENT surgeons to remove the cysts found in the throat and connected areas. In this procedure along with cyst the nearby structures and tract of the sinus and its branches and a portion of the hyoid are also removed.
