A Case of Osteoblastoma Accompanied with Concha Bullosa of the Inferior Turbinate

  • 1Department of Otolaryngology, Presbyterian Medical Center, Jeonju, Korea. juhee.hn@gmail.com


Osteoblastoma is a rare benign tumor, representing less than 1% of all bone tumors. Most cases occur in the vertebrae and in the long bones. Intranasal or paranasal osteoblastoma is particularly rare and only one case of osteoblastoma in the inferior turbinate has been reported in the world literature. Treatment is intralesional curettage or en bloc resection. Since the tumor is benign, conservative surgery is curative in about 80-90% of the cases. Concha bullosa is an abnormal pneumatization of the intranasal turbinates and inferior concha bullosa is a very rare condition. We report an unusual case of osteoblastoma occurring together with inferior concha bullosa. The tumor and inferior concha bullosa were removed by endoscopic submucosal inferior turbinoplasty, with favorable results. Related articles are reviewed and brief discussions are presented in regards to the case findings.
