Abstract

Surgical curettage or en bloc excision are the usual choice of treatment for osteoma. Local recurrence of osteoma after surgical treatment is not very common. We report a case of osteoma recurred at the grafted bone. A 5 x 8 cm sized osteoma of frontal bone was excised and then the defect was covered with calvarian bone and rib bone. Six years after reconstruction, recurrence from grafted area was noted. We completely removed the osteoma with enough normal tissue around it, after checking that the grafted bone has changed into an osteoma through a bicoronal incision. Then we covered the defect with a rib bone. The tissue was confirmed histologically as an osteoma. The recurrence of the tumor at the bone grafted site after osteoma excision is probably due to the fact that we covered grafted bone with periosteum left over osteoma. Therefore, we can learn that when we excise osteoma, galea should be carefully separated from the periphery of the tumor and that the periosteum should be completely removed, to prevent the osteoma from recurrence.
