Autologous tarsi-conjunctiva composite lamella for treatment of posterior layer eyelid defect and entropion

Abstract

Objective To investigate the application of the autologous tarsi-conjunctiva composite lamella for rehabilitating entropion resulted from defect in the posterior layer of eyelid,seeking a more stable effect of operation for repairing defect.Methods 17 eyes of 15 cases of entropion caused by posterior layer of eyelid burn injury were enrolled.In which 15 eyes suffered superior eyelid defect with a remain vertical length of eyelid less than 6 mm,2 eyes suffered inferior eyelid defect with a remain vertical length of eyelid less than 2 mm.They were treated by transplantation of autologous tarsi-conjunctiva composite lamella.The healing situation of grafting complex and eyehd position were observed in the follow-up time from 6 to 26 months,with the average of (18.7 ± 3.3) months.Results The composite lamella contected planting bed well with light color manifestation 48 h after operation in all patients.The color turned red in 1 week.The composite lamella partly vascularized in 3 weeks and completely vascularized in 6 weeks ; the surface of tarsiconjunctiva was smooth in 8 to 10 weeks.The providing valve area did not need surgical treatment.The position of eyelid margin were normal.There were random eyelashes growing after surgery in one case and has been relieved by trichiasis electrolysis.Conclusion Autogenous tarsi-conjunctiva composite lamella has a good application value and stable curative effect in rehabilitating defects in the posterior layer of eyelid.
