Abstract:

Objective: To compare the corrective effects of shortening and advancement of levator palpebrae superioris muscle and
frontal muscle flap suspension surgery for congenital blepharoptosis. Methods: Frontal muscle flap suspension surgery was adopted on
43 eyes of 33 patients and shortening and advancement of levator palpebrae superioris muscle was used on 66 eyes of 54 patients
among 87 cases by pure double eyelid incision. Follow-up visits of each patient were paid in the first, the sixth, the twelfth month after
the surgery for taking records of visual acuity, position of upper eyelid skin edge of the surgery eye, the symmetry of both eyes'
palpebral fissure, the level of palpebral fissure dysraphism, and any trichiasis and angulation deformity. Results: 79 patients got
satisfying effects and 6 patients got fine effects after the first surgery. 2 patients got insufficient correction after the first surgery and
then got satisfying effects by the second time. There is no overcorrection and nullity. Conclusion: Both of the operation methods had
positive effects. Shortening and advancement of levator palpebrae superioris muscle fits for physiology, and the level of palpebral
fissure dysraphism after the surgery was rather low and could disappear gradually. Most of the patients could choose this method but
few patients got insufficient correction. Frontal muscle flap suspension surgery has a serious level of palpebral fissure dysraphism after
the surgery and it could exist permanently. A few patients has complication of bleeding and wound dehiscence, which could be
prevented from happening with proper postoperative observation and nursing.
