The symptoms usually appear when there is inflammation of pharyngeal bursa causing<unk>  cyst. This is caused by spontaneous drainage in the nasopharyngeal cavity or because of involvement of nervous plexus. 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.
