Osteoma of the sphenoid sinus.

Key-words. Osteoma; paranasal sinuses; endoscopic sinus surgery Abstract. Osteoma of the sphenoid sinus. Objective: Only twenty cases of osteomas of the sphenoid sinus have been reported. This tumour causes progressively worsening headaches and visual disturbance and should be resected when symptomatic or fast-growing. In selected cases, endoscopic sinus surgery offers an effective alternative to open proce- dures. Case report: The authors report a case of sphenoid osteoma in a 19-year old woman. Computed tomography performed because of complaints of progressively worsening headaches identified a large osteoma of the sphenoid sinus. The clini- cal features and radiological assessment of the disease are presented together with a review of the literature. Results: The endoscopic technique used for resection of the tumour gave a very good result. Conclusion: Sphenoid osteoma is an extremely rare lesion which can be approached endoscopically in selected cases.
