This study evaluated the incidence and risk factors for temporal (facial) nerve branch injury during Mohs surgery. The authors identified high-risk anatomic zones and provided strategies for minimizing iatrogenic nerve damage during tumor extirpation and reconstruction.

The temporal branch of the facial nerve is most vulnerable in the temple and lateral forehead regions during Mohs surgery.

Knowledge of the temporal nerve course relative to surgical landmarks is essential for preventing motor nerve injury during Mohs procedures.
