Abstract

Reconstruction of the medial canthal area after excision of basal cell carcinoma poses a significant challenge in reconstructive surgery due to the region’s complex anatomical structures and its high functional and aesthetic demands. This article presents six clinical cases involving medial canthal defects of varying sizes and degrees of invasion, reconstructed using a combination of multiple local flaps. These include upper eyelid myocutaneous flaps, lower eyelid myocutaneous flaps, tenzel flaps, nasal root transposition flaps, glabellar transposition flaps, cheek transposition flaps, cheek V-Y advancement flaps, and cheek turnover flaps. All cases demonstrated good wound healing with no major postoperative complication. Long-term follow-up (over 6 months) in four patients showed satisfactory restoration in both the morphology and motor function of the eyelids. However, two patients continued to experience persistent epiphora due to lacrimal drainage system injury. The strategic combination of multiple local flaps tailored to each anatomical subunit proved highly effective in reconstructing extensive medial canthal defects, contributing to optimized long-term outcomes in both form and function.
