The Frontalis Muscle Transposition in Severe Congenital Ptosis

ABSTRACT

The frontalis sling operation for the correction of severe congenital ptosis have been used, but this method is not entirely satisfactory in some cases due to longstanding lagophthalmos, lid lag, undercorrection. So authors have used the frontalis muscle transposition in 5 patient (6 eyes) in 1996 Febuary to July with satisfactory results. The frontalis sling operation was correction method by using foreign materials in severe ptosis patients with poor levator function, however, the operation method of frontalis transposition was correction method by using patients` own muscle, so more physiologic than frontalis sling operation. And postoperative compliscations including lagophthalmos, undercorrection were less developed in patients were operated by method of frontalis muscle transposition. Therefore, the frontalis muscle transposition need careful technique anatomically but more physiological operation method than frontalis sling operation in severe congenital ptosis patients with good frontalis muscle function.
