Abstract

Purpose: The authors describe their experience with a variant of the split orbitotomy with a small medial oblique transmarginal incision for approaching a variety of lesions involving the superonasal aspect of the orbit.

Methods: Retrospective review of medical records and clinical photographs of all patients who underwent an unilateral medial oblique incision to access various intraconal lesions abutting the superomedial quadrant of the orbit. The curvature of the medial contour of the operated and contralateral eyelids were expressed with Bézier functions and compared using the R-squared coefficient of determination (R 2 ).

Results: Twenty-three patients were submitted to this surgical technique for approaching various unilateral lesions on the superonasal quadrant of the orbit. Excellent cosmesis was achieved in all eyelids, with almost imperceptible scars, and no ptosis or retraction. There was no significant difference between the postoperative medial contour of the operated and the contralateral eyelid, with R 2 ranging from 0.896 to 0.999, mean 0.971.

Conclusions: The authors' results show that the modified eyelid split approach provides a wide exposure of the superonasal quadrant of the orbit with no risk of eyelid dysfunctions or significant scars.
