A thyroglossal cyst or thyroglossal duct cyst is a fibrous cyst that forms from a persistent thyroglossal duct. Thyroglossal cysts can be defined as an irregular neck mass or a lump which develops from cells and tissues left over after the formation of the thyroid gland during developmental stages.
The symptoms are occipital headache, cough, middle ear effusion, cervical myalgia, and halitosis, i.e. bad breath. When there is an enlargement of the cyst, it causes symptoms like nasal obstruction, post-nasal discharge with foul-smelling odour, blockage of the Eustachian tube causing otalgia and secretory otitis media, retro-orbital pain.
