A Case of Thornwaldt's Cyst Removed with Nasal Endoscopy / 대한이비인후과학회지

ABSTRACT

Thornwaldt's cyst is a rare benign developmental lesion induced by persistent notocord remnants within the midline nasopharynx. Although most patients with the cyst are symptom-free, inflammation or an abscess can develop. Treatment involves excision or wide marsupialization of the cyst. In previous reports, the cysts have been removed transorally by adenoid currette, scissors, and so on. But recently by introduction of nasal endoscopy and its extended application, transnasal approach using nasal endoscopy becomes useful surgical approach to nasopharynx. We report a case of Thornwaldt's cyst which was successfully removed with nasal endoscopy in a 30-year-old man.
