Patient Story: Basal Cell Carcinoma on the Crus of the Helix Treated with Mohs Surgery

A 74-year-old female patient presented with a basal cell carcinoma (BCC) located on the left crus of the helix, the inner rim of the outer ear. The ear’s thin skin, delicate cartilage, and exposed location make surgical treatment particularly complex. For this reason, Dr. Lance Henry, Fellowship-trained Mohs Surgeon at Advanced Dermatology & Skin Cancer Center, recommended Mohs micrographic surgery—the most precise and tissue-sparing method available.

Mohs surgery is uniquely effective for skin cancers on the ear due to its stepwise approach. Cancerous tissue is removed layer by layer and examined under a microscope in real time until no cancer cells remain. This method offers the highest cure rate and preserves critical ear structures—essential for maintaining both appearance and function.

In this case, the BCC was fully removed in a single surgical stage. Dr. Henry then carefully reconstructed the area to protect the natural curvature of the ear and support healing. Just one month post-operation, the “after” photo shows remarkable results: healthy skin, preserved shape, and very little visible evidence of the procedure.

This case highlights the strength of Mohs surgery in treating cancers on high-risk, cosmetically sensitive structures like the ear. The patient was able to undergo a minimally invasive, outpatient procedure with a rapid recovery and minimal discomfort. Her outcome reflects not only successful cancer removal but also expert cosmetic reconstruction.

At 74, she now moves forward confidently—cancer-free and with her ear’s appearance beautifully maintained.
