The lower eyelid blepharoplasty using fascia ligament of orbital muscle sling and prevention of lower eyelid ectropin and its classification

Objective To study lower eyelid blepharoplasty using fascia ligament of musculi orbicularis oculi sling and prevention of lower eyelid ectropion and its classification. Methods Observing the anatomy of fascia ligament of musculi orbicularis oculi in 20 cases. There were 224 cases of lower eyelid blepharoplasty treated in our clinic from Oct.1998 to Oct. 2000 with fascia ligament of musculi orbicularis oculi sling, and set up the classification of eyelid ectropion based on it. Results The fascia ligament of musculi orbicularis oculi is a fascia fiber ligament. It starts under the lateral part of musculi orbicularis oculi and ends at lateral wall of orbita and lower eyelid tarsus . The length of the ligament is about 15mm and width around 12 mm. This series of lower eyelid blepharoplasty were using fascia ligament of musculi orbicularis oculi sling in 224 cases. There were 5 cases who occurred ectropion within a few days postoperatively. All of them got good results followed through two weeks to two years after operation. The ectropion can be classified to 0～Ⅲ four degrees and sixteen grades. Conclusion The fascia ligament of orbital muscle sling is a new idea for lower eyelid blepharoplasty in considering with musculi orbicularis oculi lifting or orbital fascia lifting. The classification of ectropion is a key to evaluate ectropion on lower eyelid.
