Objective:To determine if a superior tarsectomy improves the ptosis corrective ability of the super maximum levator resection in cases of severe blepharoptosis with poor levator function(less than 5 mm) .Design:Retrospective,consecutive case series.Participants:Patients who underwent super maximum levator resection with(8 eyelids) or without superior tarsectomy(10 eyelids) at one institution.Methods:Chart review of patients who underwent super maximum levator resection with or without superior tarsectomy.Data regarding eyelid position,surgical outcome,and postoperative complications were evaluated.Main Outcome Measures:Margin reflex distance-1(distance [mm] between corneal light reflex and upper eyelid margin) ,bilateral eyelid symmetry,and postoperative complications.Results:A statistically significant improvement in ptosis correction was demonstrated when integrating the superior tarsectomy with the super maximum levator resection(P=0.029) .In addition,the superior tarsectomy significantly decreased the incidence of undercorrection(margin reflex distance-1 values less than 2.0 mm) compared with the super-maximum levator resection alone(12.5% vs.70% ;P=0.023) .Improved postoperative eyelid symmetry within 1.0 and 1.5 mm was demonstrated in cases treated by the superior tarsectomy.Postoperative complications were similar in both treatments.Conclusions:The super maximum levator resection combined with superior tarsectomy can correct severely ptotic eyelids with Berke levator function ranging from 3 to 4.5 mm.
Objective: To determine if a superior tarsectomy improves the ptosis corrective ability of the super maximum levator resection in cases of severe blepharoptosis with poor levator function (less than 5 mm). Design: Retrospective, consecutive case series. Participants: Patients who underwent super maximum Levator resection with (8 eyelids) or without superior tarsectomy (10 eyelids) at one institution. Methods: Chart review of patients who underwent super maximum levator resection with or without superior tarsomyomy. Data regarding eyelid position, surgical outcome, and postoperative compound were evaluated as . Main Outcome Measures: Margin reflex distance-1 (distance [mm] between corneal light reflex and upper eyelid margin), bilateral eyelid symmetry, and postoperative complications. Results: A significant significant improvement in ptosis correction was demonstrated when integrated the superior tarsectomy with the super maximum levator resection (P = 0.029) .In addition, the superior tarsectomy signifi cantly decreased the incidence of undercorrection (margin reflex distance-1 values less than 2.0 mm) compared with the super-maximum levator resection alone (12.5% vs. 70%; P = 0.023). Implanted postoperative eyelid symmetry within 1.0 and 1.5 mm was demonstrated in cases treated by the superior tarsectomy. Postoperative complications were similar in both treatments. Conclusions: The super maximum levator resection combined with superior tarsectomy can correct severely ptotic eyelids with Berke levator function ranging from 3 to 4.5 mm.
