Mohs Micrographic Surgery for Advanced Centrofacial Tumors

Mohs surgery was developed for the treatment of advanced skin cancers. Advanced centrofacial tumors are among the most challenging lesions.

The objective of the study was to review the most complex midface cases from our practice and to delineate how to plan the approach to these lesions, how to remove them in a step-by-step fashion, and how the patients were managed in a multidisciplinary manner when indicated.

We reviewed 15 years of the most complex tumors to present to our practice for which Mohs micrographic surgery was performed. Follow-up for patients ranged from 3 to 13 years and is ongoing.

Twenty cases were identified in which tumors of the central face extended to bone and created extensive operative wounds. Eleven lesions were recurrent at presentation, and 9 had perineural disease. These cases are reviewed sequentially and demonstrate the challenges, successes, and pitfalls of Mohs micrographic surgery in the treatment of the most difficult tumors. Two patients died from disease.

Mohs surgery is an excellent technique for the removal of extensive midfacial lesions and allows for the surgical removal of lesions that might otherwise be considered inoperable. Approach to these lesions requires careful planning, meticulous surgical technique, excellence in histology, and an experienced reconstructive surgeon. Such tumors often require a multidisciplinary approach, imaging, and adjuvant therapy. All such cases require diligent follow-up. Although many such lesions will be cured, regional recurrence and metastasis may result, even when clear margins are achieved.
