Ptosis surgery using Mersilene mesh suspensory material.

Frontalis suspension procedure using a Mersilene mesh sling was performed on 23 ptotic eyelids of 22 patients (age range 3 to 35 years) with poor or absent levator function. The surgical technique used was a modified Fox's method. The mean palpebral fissure height was 3.1 mm preoperatively and increased to 8.0 mm after the operation. No serious complication was seen postoperatively and during an average follow-up of 25 months. In one case with a cosmetically inadequate result, the upper third of the initially implanted Mersilene mesh was removed during reoperation and histological examination of the specimen revealed fibrovascular tissue invasion through the mesh fibres. Mersilene mesh appears to be an effective and safe alternative sling material for brow suspension surgery, giving good permanent results for cases in which autogenous fascia lata was inappropriate.
