It is rarely that occur on the nasal tip and nasal septum at same time and rarely repair of using nasal septum mucosa. The authors treated a child with dermoid cyst in the nasal tip and septum. Only the dermoid cyst at the tip of the nose caused the change of appearance. Dermoid cyst of nasal septum did not cause any clinical symptoms. She underwent excision of the dermoid cyst at the tip of the nose and endoscopic surgery for the dermoid cyst in the nasal septum and used the nasal septum mucosa for repair at the same time. After 6 months of recovery, the appearance of the nasal tip recovered well without obvious scar, the nasal septum area recovered well, and the local stoma was unobstructed without recurrence. The authors found that this kind of nasal septal cyst with no clinical symptoms can achieve good therapeutic effect through endoscopic surgery and repair of using nasal septum mucosa, with less damage, rapid recovery, and good prognosis.
