Tornwaldt's cyst.The development of a cyst in the nasopharyngeal nasopharyngeal pertaining to the nasal and pharyngeal cavities. nasopharyngeal meatus see nasopharyngeal meatus. nasopharyngeal spasm see reverse sneeze. bursa (Tornwaldt's cyst) occurs in about 3% of the population. It is the result of persistent embryonic communication between the anterior tip of the notochord notochord (nō`təkôrd'), in biology, supporting rod running most of the length of animals of the phylum Chordata and present at varying times in the life cycle. and the nasopharyngeal epithelium. This communication usually disappears during the second month of gestation. [1] Tornwaldt's cyst is located at the midline mid·line n.
