Interventions
patients will receive regional anesthesia using ultrasound guidance. Target nerves (e.g., great auricular nerve, auriculotemporal nerve and lesser occipital nerve) will be identified and anesthetized under real-time ultrasound visualization to ensure accurate needle placement and local anesthetic spread.
patients will receive general anesthesia.
