Abstract

Congenital ptosis is defined as upper eyelid falling that presents at birth or in the first year of life. It is considered the most prevalent type in children and appears to be more common in males than females .Congenital ptosis has physical, psychological, and functional effects. The two main surgical principles used in the management of congenital ptosis with poor levator function are either frontalis based procedures namely (frontalis sling or frontalis advancement flap) or levator muscle resection. Frontalis based procedures are more widely used for cases with poor levator function of less than 5mm. Cases with fair and moderate levator function are preferably managed by levator resection. Some reports have shown that following levator resection there was some improvement in levator function. The availability of a technique that changes levator function from poor to fair would make the levator resection technique a preferred primary surgical option for such cases.
