Abstract

Thornwaldt’s bursa, also known as nasopharyngeal bursa, is a recess in the midline of the nasopharynx,which is produced by persistent notochord remnants. If the opening of the bursa is occluded, benign midline nasopharyngeal mucosal cyst called Thornwaldt cyst develops. Although Thornwaldt’ cyst is not a rare mass, nasopharyngeal obstruction is a rare condition deal with the enlargement of cyst. Cysts are almost always asymptomatic. However, if they become infected or exposed to trauma they can cause some symtoms include halitosis, occipital headache and postnasal drip. Radiological and endoscopic examination can be used to diagnose the cyst. The differential diagnosis should include a seromucinous glands cysts, intra-adenoid cysts, prevertebral abscess, meningocele or meningo-encephalocele. In this study, we present our approach towards patients diagnosed with symptomatic Thornwaldt cyst along with a literature review.
