Nasal dermoid cyst is a rare benign lesion. The mainstay of treatment for a nasal dermoid cyst is surgical excision, which aims to remove the cyst and associated structures to prevent recurrence. We report a case of a 30-year-old man with nasal dermoid cyst, without intranasal or intracranial extension. The patient underwent open rhinoplasty technique for dermoid cyst excision. He had an uneventful postoperative recovery and was discharged well. The cyst and associated structure were successfully removed. There was no evidence of recurrence and complications postoperatively after 2 years of follow-up.
