[2025-09-30T19:32:09.527132] [PI reasoning] **Identifying nerve injury**

I need to determine which nerve is responsible for numbness after a parotidectomy. It sounds like the great auricular nerve (C2-C3) is the key player here as it supplies sensation to the ear and angle of the mandible. When shaving, that numbness occurs in parts of the face and neck where this nerve is affected. Additionally, while the auriculotemporal nerve also passes through the parotid area, the primary cause of the numbness is probably the great auricular nerve being sacrificed during the procedure. I'd like to confirm this with some literature.
