Efficacy and Safety of Cryotherapy for Residual Tarsus and Free Tarsal Graft Implantation After Excision of Malignant Eyelid Tumor

Abstract

To examine the usefulness and safety of cryotherapy for residual tarsus and free tarsal graft implantation for eyelid reconstruction after excision of malignant eyelid tumor. Fifteen patients with 17 eyelid malignancies (10 sebaceous gland carcinomas and 7 basal cell carcinomas) who underwent eyelid reconstruction between June 2017 and February 2021 were included in the study. In these patients, the tumors were resected in the entire eyelid layer including the safety margin. Only sebaceous gland carcinomas patients underwent cryotherapy at the residual tarsus margin. Then, a free tarsal graft taken from the ipsilateral or contralateral upper eyelid was transplanted into the eyelid plate defect, and anterior lamella reconstruction was performed with an orbicularis oculi myocutaneous advance flap. In both the non-cryotherapy and cryotherapy groups, there were no serious complications such as dropout or necrosis of the free tarsal graft. There were no differences in the occurrence of complications such as eyelid retraction or trichiasis between the 2 groups, but 1 patient who underwent cryotherapy required revision surgery to correct eyelid retraction. In addition, there were no complications on the donor side associated with free tarsal graft collection. The use of a free tarsal graft in the reconstruction of eyelid malignancies is relatively effective and safe, and if vascular support of the anterior lamella is obtained, cryotherapy is less likely to affect the viability of the free tarsal graft and may contribute to a decrease in local recurrence.
