To assess the results and effectiveness of a small incision technique for ptosis repair.

Twenty three ptotic eyelids of 17 patients were repaired through a small incision between March 2005 and December 2005. Levator function and pre- and postoperative upper eyelid marginal reflex distances (MRD1) were checked. The small incision was executed on the eyelid crease, with a length of approximately 10.0~12.0 mm. Two 6-0 Ethilon stitches were placed to the tarsus after detecting levator aponeurosis with a Desmarres retractor.

Of the 32eyes, 9 eyes had congenital ptosis and 23 eyes had acquired ptosis. The mean follow-up time was 12.1±3.4 months, with a levator function of 7.6±2.1 mm, preoperative MRD1 of 0.2±0.4 mm, and postoperative MRD1 of 2.6±0.3 mm. Two eyelids remained mildly undercorrected and required an additional operation.

The small incision technique for ptosis correction is safe and precise, allowing more rapid recovery from surgery. The Desmarres retractor allows the levator to be found easily without complications. In addition, the small incision technique for levator repair is useful for congenital ptosis with good levator function as well as acquired ptosis.
