Osteoma of the paranasal sinuses.

Osteamas of the paranasal sinuses are rare, They often appear as a coincidental finding on X-ray in patients having radiographs for same other reasons. Tomographic evaluation is the mainstay surgical access and its subsequent follow up. We report a series of 20 cases of osteamas of the paranasal sinuses who underwent surgery for their symptoms. Wide exposure at surgery is necessary for complete or near complete removal. Tumour close to the dura, optic-nerve and internal carotid artery may be left Close and long period offollow-up is essential, especially when the tumour is partially left behind. In our experience, the rate of growth of tumour is very slow and a wait and watch policy can he adopted for very small tumours and those that are incompletely resected.
