Frontoethmoidal osteoma: a stereotactic-assisted sino-orbital approach.

A 28-year-old woman had an extensive osteoma arising in the frontoethmoidal sinuses and involving the orbital roof. The tumor was successfully removed by means of a combined sinus endoscopic and orbital approach, with the assistance of stereotactic localization. The patient had postoperative ptosis, diplopia, and supraorbital nerve anesthesia, which all resolved over a 3-month period. A stereotactic-assisted, sino-orbital approach to selected frontoethmoidal osteomas may provide a viable alternative to an orbitocranial approach.
