Participant Flow

The patients were recruited as part of the preoperative information discussion. All patients received an intermediate cervical plexus block and a facial nerve block (cervical branch, superficial cervical ansa). The decision on an additional perivascular infiltration was made by an experienced physician on the basis of sonoanatomic properties.
