Two fascia sling techniques similarly effective for upper eyelid ptosis in study

Two techniques for placing an upper eyelid fascia sling — the monotriangular and bitriangular methods — are similarly effective for managing patients with congenital upper eyelid ptosis, a randomized study found.
However, the monotriangular method requires less fascial tissue, produces a smaller scar and involves a shorter anesthesia period, the authors noted.
Abbas Bagheri, MD, and colleagues randomly assigned 30 upper eyelids of 19 patients to treatment with one of the two fascia sling placement techniques. Surgeons used the monotriangular fascia sling method, or modified Fox method, on 15 eyes. The other 15 eyes were treated with the bitriangular fascia sling method, or modified Crawford method.
All patients had congenital upper eyelid ptosis and poor levator function, according to the study.
Surgery significantly improved eyelid fissure height an average of 2.7 mm in the bitriangular group and an average of 3.4 mm in the monotriangular group, with no significant difference between the groups, the authors reported.
In addition, both groups had similar rates of early and late complications, such as corneal epithelial defects, entropion and undercorrection, and no patients required reoperation for recurrent ptosis, they noted.
The study is published in the May/June issue of Ophthalmic Plastic and Reconstructive Surgery.
