Partial Parotidectomy under Local Anaesthesia without Regional Block Assisted by Electromyographic Facial Nerve Monitoring - A Case Report.

The Rationale: This study describes a partial parotidectomy (PP) under local anaesthesia (LA) without regional block (LAwRB) assisted by electromyographic monitoring of the facial nerve, to consolidate the feasibility, efficacy and safety of these procedures without general anaesthesia (GA). Patient Concerns: An 82‑year‑old with a lump in the left parotid gland suspected for non‑Hodgkin lymphoma (NHL) needed a histological examination to start chemotherapy. Diagnosis and Treatments: Because of multiple comorbidities, the authors performed a PP under LAwRB electromyographically guided by the NIM Vital (Medtronic)™. Outcomes: The procedure was quick and did not require conversion to GA. The histopathological examination confirmed the NHL. No haematoma, sialocoele, earlobe numbness and transient or permanent facial palsy were observed. Take-Away Lessons: The electrophysiologic monitoring of the facial nerve improves the efficacy, safety and feasibility of parotid surgery under LA, avoiding adverse effects of GA, need of regional block and reducing hospital stay.
