Abstract
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. METHODS: This study included 116 patients (175 eyelids) with moderate or severe ptosis who underwent combined excision of the levator muscle and the tarsus. For cases of bilateral blepharoptosis with different levator functions between the two eyelids, surgery was performed for more severe side first and for the other side 6�months later. Postoperatively, the correction and symmetry results were evaluated and analyzed using chi-square testing by SPSS (version 10.0). RESULTS: Adequate or normal correction was achieved in 149 eyelids (85.1%). The difference in correction results did not differ significantly between moderate and severe cases. With a two-stage operation, 98 patients (84.5%) obtained good or fair asymmetry results, and no statistically significant difference existed between the bilateral and unilateral cases. CONCLUSION: The described technique appears to be effective for both moderate and severe ptosis, with better biomechanics and a satisfying aesthetic outcome.
