Regional flap combined with xenogeneic acellular dermal matrix transplantation for eyelid defect / 眼科新进展

ABSTRACT

Objective To observe the clinical effects of eyehd reconstruction by regional flap combined with xenogeneic acellular dermal matrix transplantation for eyelid defect after malignant tumor excision.Methods Thirty-five cases (35 eyes) in our hospital were selected as the objects.Among them,basal cell carcinoma was 21 cases,meibomian gland carcinoma was 13 cases,squamous cell carcinoma was 1 cases;12 cases of upper eyelid and 23 case of lower eyelid were involved.All patients were subjected to intraoperative frozen,and the incision margin was determined according to the frozen results.After resection of the tumor,the eyelid had full-thickness defects in different degrees.The xenogenic acellular dermal matrix was used to replace the conjunctival tarsal tissue,and the adjacent flap or transposition flap was used to repair the eyelid defect according to the size of skin defect.The healing of flap,oral repair film,eyelid closure and adhesion were observed.Results After half a year follow-up,the acellular dermal matrix were completely dissolved by crawling the conjunctival epithelium covering,the flap healed with no flap necrosis.28 patients recovered well after operation without hypophasis and entropion,ectropion.4 patients had mild hypophasis,and there was no case of exposure keratitis.3 patients were with mild symblepharon.Conclusion The acellular dermal matrix can replace tarsal conjunctival tissue,which combined with regional flap has good clinical curative effect for eyelid defect after malignant tumor excision.This treatment can reduce the pain of patients who take oral mucosa and avoid the reoperation of eyelid reconstruction.
