      We report two cases of ectopic inverted tooth, which were removed by endoscopic endonasal surgery. Case 1 was a 9-year-old boy who had no symptoms. A white mass was incidentally found in his right nasal cavity, and the tooth was removed easily with endoscopic endonasal approach. Case 2 was a woman who had recurrent episodes of right maxillary sinusitis. Imaging examination revealed that a tooth was buried in the posterior wall of the antrum. After creating a large middle meatal antrostomy by endoscopic endonasal approach, we could observe the tooth fixed firmly to the surrounding bone. We removed the tooth completely by drilling the surrounding bone with a curved burr. They are both doing well after operation. Recent improvement in instruments has made the endoscopic endonasal approach possible. This approach is useful for removing ectopic teeth because it is less invasive to the patient than a conventional approach.

Key words : ectopic inverted tooth, nasal cavity, endoscopic approach, maxillary sinus
