Ringing the Bell's: A Mohs complication worth listening to - A case report

We report an uncommon case of transient Bell's palsy-like facial paralysis following local anesthesia during Mohs micrographic surgery of the left conchal bowl. The temporary complication resolved spontaneously without intervention and is suspected to have resulted from anesthetic diffusion to the facial nerve via the tragal region. This case highlights the importance of understanding facial nerve anatomy during procedures in the auricular area and the need to counsel patients regarding rare but benign complications of local anesthesia.
