The Frontalis Sling Operation Using Preserved Fascia Lata: Modified Crawford Technique

ABSTRACT

PURPOSE: For the correction of ptosis with very poor levator function, frontalis sling operation with various materials has been used. The purpose of this study was to evaluate the effect of the modified Crawford technique using preserved fascia lata. METHODS: The photographs and charts of 46 patients who underwent frontalis sling operation using preserved fascia lata from June 2001 to February 2004 at our hospital were retrospectively reviewed. The eyelid crease approach was used with the suturing of the sling material directly to the tarsus. RESULTS: The patients were 27 males and 19 females. There were 20 (44%) unilateral cases and 26 (56%) bilateral cases. The age of the patients ranged from 1 to 65 years at the time of surgery, with an average age of 8.3 years. The success rate was 93% (43/46 patients) for a mean postoperative follow-up of 9 months (range 4~26 months). The complications consisted of one case of overcorrection and 2 cases of undercorrection. Knot exposure occurred in 2 cases. CONCLUSIONS: The modified Crawford technique using preserved fascia lata appears to be an effective treatment for severe ptosis. The lid crease formation provides good cosmetic results and the direct suturing of the preserved fascia lata to the tarsus prevents its migration.
