Fronto-ethmoidal osteomas are the most frequent benign tumors of the paranasal sinuses, and may evolve with complications by compression of adjacent structures. The case is a 63-year-old female patient, who consulted about increased nasofrontal volume, headache and diplopia. After the clinical exam, she presented a facial asymmetry with lateralization of the right eyeball and exophthalmus. Computed tomography of the sinuses showed a lesion that partially occupies the frontal sinus, ethmoidal sinus and part of the nasal cavity. The anatomical care and surgical planning was developed in a stereolithographic model while the total excision surgery was performed with the help of the piezoelectric system. Histological examination confirmed the diagnosis of osteoma. A successful reconstruction is obtained, fully recovering symmetry and ocular function.
