Surgical strategies in the treatment of symptomatic osteomas of the orbital walls

WE PRESENT A series of 19 surgically treated osteomas involving the orbital walls. Eight were localized at the junction of the frontal sinus and orbital roof, three were frontoethmoidal, two were of the orbital roof, one of the lateral wall, one of the orbital floor, and four involved all the walls of the orbit and were termed panorbital. All tumors at the junction of the frontal sinus and the orbital roof as well as those originating from the orbital roof proper were removed by frontal craniotomy. In the three that were frontoethmoidal, osteotomies were performed. Lateral and inferior orbitotomies were done when the corresponding orbital walls were affected. The four panorbital osteomas required large frontotemporal craniotomies in association with superolateral orbitotomy and zygomatic and/or malar osteotomy, when necessary. Satisfactory cosmetic and functional results were obtained in all but two cases of panorbital osteomas, in which the neurological deficit worsened after surgery. We discuss the choice of the various approaches described, with reference to the relevant literature.
