[Autogenic facia lata suspension for correction of paralytic ectropion].

Objective: To evaluate the outcome of autogenic facia lata suspension in the treatment of paralytic ectropion. Methods: It was a retrospective case series study. The clinical records of 21 patients (21 eyes) who were treated for paralytic ectropion with autogenic facia lata suspension between January 2015 and September 2017 at Beijing Tongren Hospital were analyzed. In the 21 patients, 7 were male and 14 were female. The range of age was 20-74 years and the mean age was (61±14) years. All of the participants received facia lata suspension for the correction of ectropion. Some of the patients also received associated wedge resection of the tarsus or lateral tarsal strip procedure. The anterior lamella was reconstructed with local flaps in some patients. The preoperative and postoperative degree of ectropion was measured. Paired sample t test was used to compare the preoperative and postoperative data. Results: Postoperative follow up for patient was conducted for 6-38 months. Residual lagophthalmos of 3 mm or more were present in 3 cases. Mild lower eyelid ectropion recurred in 1 patient one year after surgery. The rest cases achieved satisfactory aesthetic outcomes. No complication in the donor site was observed. The preoperative scleral show was (3.02±1.31) mm, and the postoperative data was (-0.05±0.72) mm. The preoperative margin reflex distance 2(MRD2) was (8.83±1.77) mm, and the postoperative MRD2 was (5.43±0.78) mm. The preoperative lagophthalmos was (6.17±1.91) mm, and the postoperative data was (1.98±1.09) mm. The differences between the preoperative and postoperative data were significant (t=13.530, P=0.000;t=11.913, P=0.000; t=11.882, P=0.000). Conclusion: Autogenic facia lata suspension is an effective method for the correction of paralytic ectropion, with good aesthetic outcome, low recurrence rate and few complications.
