Methods\ The septal chondromucosal island flap based on the nasal alar basal artery and nerve was passed through the subcutaneous tunnel of the infraorbital region and sutured to the defect to reconstruct the tarsoconjunctival plate of the missing eyelid. The rotation arch of the flap had its pivot point lateral to the nasal ala. Results\ The procedure was performed on three patients. The postoperative course was uneventful. All the flaps survived completely. No operative complications occurred. Conclusions\ The technique provides well vascularized tissue with sensitive innervation, without damage to the other eyelid and severe deformities in the donor site. The septal chondromucosal island flap allows reconstruction of the tarsoconjunctival layers of the eyelid, providing cartilaginous support and a mucous lining. The flap can provide enough tissue to repair partial or entire tarsoconjunctival defects of the upper or lower eyelid or combined defects of the upper and lower eyelids. \;展开更多
