A RARE CASE OF CONCHA BULLOSA OSTEOMA IN A GERIATRIC PATIENT

摘要

The most common location of osteoma is the mandible in head and neck. In the paranasal sinuses, it is most commonly located in the frontal sinus and then in the ethmoid and maxillary sinuses, respectively. Osteomas appear rarely in the nasal cavity and even more rarely in the turbinates. A sixty six year old woman who had presented with complaints of nasal obstruction, left-sided facial pain and headache was referred to our department. Paranasal sinus computed tomography (CT) revealed a pneumatized left middle turbinate, and on coronal, sagittal, and axial CT sections an ellipsoid hyperdense lesion measuring approximately 22 x 13 mm was evident inside the left aerated middle turbinate. We performed an endoscopic partial turbinectomy under general anesthesia. The patient had no complaints during the subsequent 3-month follow-up. The pathologic diagnosis was osteoma.
