Background and objective: A variety of biologic or synthetic materials have been used in brow suspension ptosis surgery. We describe extrusion and granuloma formation in 5 cases of congenital ptosis operated with Mersilene mesh sling.
Patients and methods: Case reports with review of literature.
Results: Two cases of extrusion and 3 cases of granuloma formation were encountered in 79 eye lids of 52 (6.3%) patients performed for the treatment of congenital ptosis. Mersilene mesh fibers in the cut surface and a foreign body reaction were found by microscopic evaluation of tissue harvested at the time of surgical removal of the sling.
Conclusion: Despite the operative precautions, the probability of extrusion and granuloma formation should be in mind in cases of congenital ptosis operated with Mersilene mesh sling, a synthetic material.
