Infraglabellar Transnasal Bilobed Flap in the Reconstruction of Medial Canthal Defects

We investigated the effectiveness of reconstruction using an infraglabellar bilobed flap of transnasal skin and subcutaneous tissue for patients with medial canthal defects. Our noncomparative interventional case series involved 11 consecutive patients with medial canthal defects following Mohs micrographic excision of basal cell carcinoma. The medial canthal area was divided into 3 zones: zone 1, just above the medial canthal tendon; zone 2, centered on the medial canthal tendon; and zone 3, just below the medial canthal tendon. Primary closure was achieved easily with a good cosmetic result for all 3 zones. There were no complications or further procedures required. The outcome measures documented clinically and photographically included complete closure of the defect, cosmetic appearance, complications, and further surgery.
