Why Mohs is preferred on the nose, ears, eyelids, and lips

Mohs surgery is especially valued for skin cancers in cosmetically and functionally critical areas, the nose, ears, eyelids, lips, and around the eyes, and the reasons come down to two things Mohs does uniquely well.

First, tissue conservation. These areas have little spare skin, and every millimeter matters for both appearance and function. Because Mohs removes only tissue that actually contains cancer, guided by microscopic mapping, it spares the maximum amount of healthy skin, crucial where a slightly larger excision could distort an eyelid, notch a lip, or deform a nostril. Second, the highest cure rate. These locations also tend to have anatomy where tumors can extend in unpredictable ways, and the complete margin examination of Mohs catches extensions a standard excision might miss, reducing the chance of recurrence in a spot where re-treatment would be even more difficult.

For cancers on these features, the combination of maximum cure and minimum tissue sacrifice is exactly what is needed, which is why guidelines favor Mohs there. Patients facing a skin cancer on the central face should expect Mohs to be considered, and should value the tissue preservation it offers in areas where the cosmetic and functional stakes are highest. Once the tumor is clear, the choice of repair is what shapes the final appearance.
