Osteoma of paranasal sinuses is a rare benign tumour arising from the proliferation of compact or cancellous bone. They are more common in frontoethmoidal region where as osteomas of sphenoid or maxillary region are rare. These tumors may be incidentally detected on radiographs, or may grow to produce symptoms if extends into orbit or skull base.
