Clinical outcome of surgical treatment for periorbital basal cell carcinoma.

Basal cell carcinoma (BCC) has a predilection for the periorbital region, which is a special, prominent, cosmetic, functional area to protect the eyeball. For squamous cell carcinoma and melanoma, extensive resection with reconstruction is performed. In contrast, for BCC, resection is often confined to a small to medium-sized area, necessitating higher-quality reconstructive surgery. We analyze the surgical outcomes of treatment for periorbital BCC, and evaluate reconstruction method after resection. Forty-nine patients with periorbital BCC had surgery in our hospital over 20 years. Age, gender of the patients, and size, localization, and histology of the tumor, and surgical procedures, and their early and late complications were analyzed retrospectively. BCC was most frequently occurred in the lower lid (55%), followed by inner canthus (19%), upper lid (17%), and outer canthus (9%). The histologic classifications were solid (80%), morphea (7%), mix (7%), superficial (2%), keratotic (2%), and adenoid (2%). Recurrence of the tumor was observed in 2 advanced cases in patients treated with resection of the tumor including surrounding tissue 5 mm from the margin. A rotation advancement cheek flap procedure was most frequently applied. Horizontal shift of the skin was most effective to prevent postoperative lagophthalmos. BCC occurred most frequently in the lower lid within the periorbital area. Rotation advancement of cheek flap with horizontal shift of the skin is most effective procedure in both appearance and function of the eyelid.
