経鼻内視鏡下手術により摘出した原発性鼻中隔囊胞例

Nasal septal cyst often occurs as a complication after septoplasty or rhinoplasty, and has also been reported as a phenotype of pleomorphic adenoma, dermoid cyst, tuberculosis, or aneurysmal bone cyst in the final pathological diagnosis. Among these, a primary simple cyst of the nasal septum is extremely rare. Although no treatment strategy has been established for a nasal septal cyst, several surgical methods, such as cyst fenestration, open septorhinoplasty, or and total excision have been reported. Total excision is recommended in cases with no history of septal surgery to prevent recurrence of the lesion; however, careful handling is necessary to avoid damage to the L-strut and keystone area during the surgery, to prevent postoperative nasal deformity.
