A Modified Technique Combining Excision of the Levator Muscle and Tarsus for Blepharoptosis in Asians: A 6-Year Experience with 116 Cases

摘要

Background In patients with blepharoptosis, the function of levator muscle is insufficient or completely absent, causing blepharoptosis in various degrees. For mild or moderate blepharoptosis, levator advancement or resection is commonly performed. However, in severe cases, undercorrection results and recurrence often occur even a great length of levator muscle is resected. Because the levator muscle makes the upper eyelid move in a physiologic direction, exerting the function of residual levator muscle is still a more preferred approach for correction of blepharoptosis. This study combined tarsus resection with levator resection. The resected tarsus can offset the amount of the levator excised, making this technique applicable for severe cases.
