Large Orbital Osteoma Arising from Orbital Roof: Excision through an Upper Blepharoplasty Incision

Abstract

Osteoma is the most common benign tumor of facial bony structure. Intraorbital extension is extremely rare. We report a case of intraorbital, pedicled osteoma originating from the left orbital roof. The patient's ophtalmological examination revealed; only light perception due to the severe amblyopia and posterior capsular opacification in the right eye, and complete visual acuity in the left. His left eye was proptotic and directed to downward lateral gaze position. Using upper blepharoplasty incision, the osteoma was completely excised. There were not any postoperative complications and all ocular symptoms in the left eye were resolved after 1 month.

Orbital cellulitis secondary to giant sino‐orbital osteoma: A case report

“…For symptomatic cases of sino‐orbital osteoma specially giant osteomas, as reported in our patient, different surgical approaches are recommended from a pure external approach to a complete endoscopic technique 1,2,13‐17 . In the recent medical literatures, difficult cases are treated by endoscopic approaches and the indications for the external approach is limited to giant dense osteomas that cannot be excised by pure endoscopic techniques 13‐17 .…”

“…1,2,6,[10][11][12] For symptomatic cases of sino-orbital osteoma specially giant osteomas, as reported in our patient, different surgical approaches are recommended from a pure external approach to a complete endoscopic technique. 1,2,[13][14][15][16][17] In the recent medical literatures, difficult cases are treated by endoscopic approaches and the indications for the external approach is limited to giant dense osteomas that cannot be excised by pure endoscopic techniques. [13][14][15][16][17] Although pure endoscopic approach, due to the less morbidities and time of hospitalization, is the preferred method for excision of the sinus osteomas, in cases with large and dense osteomas, to avoid damage to the orbital soft tissues and lengthening the operation time, the surgeon must be flexible to change the approach to the external one.…”

Sino-orbital osteoma with osteoblastoma-like features: case reports

“…Most of the orbital osteomas arise from the adjacent paranasal sinuses. Although asymptomatic, small paranasal sinus osteomas are relatively common; sino-orbital osteomas are rare and have been published in a few reports [1][2][3].…”
