Thornwaldt cyst (Tc) is a benign mass, usually localized in the median plan of the nasopharynx. It is generate from permanent notochord remainings. The pharyngeal bursa-being an embryological residual-occurs in 3% of healthy adults. ⋯ Asymptomatic patients do not necessitate surgery, whereas symptomatic cysts need surgical treatment by a transnasal or transoral access. Marsupialization is the method of option to avoid recurrence. This review provides fundamental knowledge on Tc from an objective perspective.
