초록

Purpose: Even in a small levator resection for blepharoptosis, 10-13mm of Müller's muscle and levator aponeurosis is resected. To solve the problem, Müller's muscle was detached from the superior tarsal border and conjunctiva, and the muscle with overlying levator aponeurosis was advanced on the upper tarsus as a composite flap. The purpose of this study is to evaluate the effectiveness of the Müller's muscle-levator aponeurosis complex advancement technique for the correction of blepharoptosis.
Methods: From 2003 to 2008, 107 patients(183 eyes) underwent the advancement procedure of the Müller’s muscle-levator aponeurosis composite flap for blepharoptosis. The advanced composite flap was fixed 3 mm below the superior tarsal border and 2-3mm of distal flap stump was left after trimming up to 5mm. The results of the operations were evaluated.
Results: The mean age of the patients was 35.2 years and 83 patients(145 eyes) were followed up for a mean of 16.7 months. 128 eyes(88.3%) showed a normal level of upper eyelid margin(MRD1 4.1-5.0mm) or less than 1mm ptosis(MRD1 3.1-4.0mm). 10 eyes(6.9%) showed 1-2mm ptosis(MRD1 2.1-3.0mm). 7 eyes(4.8%) showed more than 2mm ptosis which required secondary correction. About 80% of the 183 eyes needed no trimming of the flap stump with 5-6mm of composite flap advancement and 20% had about 3mm of the flap stump trimmed with 8-9mm of composite flap advancement (shortening of the levator complex).
Conclusion: Müller’s muscle-levator aponeurosis complex advancement technique offers several advantages: There is no, or minimal, sacrifice of the normally functioning Müller’s muscle; it is more physiological; it is reproducible and it is predictable-with gratifying results for blepharoptosis.
