Supplementary Material for: Reconstruction Techniques for the Medial Canthus and Lateral Nasal Wall: A Case-Based Learning Approach.

Introduction: Reconstruction of the medial canthus and lateral nasal wall poses a significant challenge in dermatologic surgery due to the area’s complex, concave, three-dimensional anatomy and proximity to critical structures like the nasolacrimal system. Case presentation: This case-based learning approach details three different techniques on the management of extensive defects involving the medial canthus and lateral nasal wall, focusing on three different surgical techniques: the Mustardé flap, a combination of flaps with a graft, and a supraclavicular skin graft. All three approaches achieved satisfactory clinical and cosmetic outcomes. Conclusion: Successful reconstruction in this region requires a multidisciplinary approach that carefully integrates facial aesthetic units while preserving the functional integrity.
