Superior orbital rim grinding as a novel surgical technique to approach superior and posterior orbital tumors.

Purpose: To describe a novel surgical technique aimed to approach those orbital lesions located superior and posterior to the equator of the globe.

Methods: We describe a novel surgical technique that was performed in four patients to approach intraorbital tumors superiorly and posteriorly located. This technique was completed through an upper eyelid skin crease followed by grinding the superior orbital rim to achieve complete removal of the lesions.

Results: Complete removal of the lesion was accomplished in every case. No intraoperative complications were observed in any of the patients. During the follow-up period, one patient presented with frontal hypersensitivity and one with diplopia.

Conclusions: In the case series presented, the upper eyelid skin crease approach with grinding of the superior orbital rim proved to be a safe and effective surgical technique to remove lesions located superior and posterior within the orbit in our series. More studies are needed to further evaluate the efficacy and long-term results of this approach.
