Procedure: Group 1 will receive 10ml of 0.25% bupivacaine
Procedure: Group 2 will receive 10ml of 0.25% ropivacaine on each side.
After placing the patients in a supine position with the neck slightly extended and rotated away from the side to be blocked,the procedure will be performed under sterile aseptic conditions.The sternocleidomastoid muscle will be identified,and a high-frequency (1O MHz) linear probe will be positioned transversely over the muscle,between the mastoid and clavicle. The cutaneous nerves of the cervical plexus,visible as round hypoechoic structures in the fascial plane beneath the muscle,will be targeted using a 22-gauge short block needle (5 cm) inserted in-plane with the transducer. Negative aspiration will be performed during injection to avoid inadvertent intravascular delivery. An emergency crash cart will remain available throughout the procedure.

Started Jan 2026 (actual). Primary completion is estimated for Dec 2026, 11 months after the start.
Of 2,089 non-industry interventional studies with no phase under Pain, Postoperative, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 23. This study's planned 11 months is close to that.
Counting every sponsor, half of 2,102 studies reached it within 11 months; a quarter within 6 and three quarters within 23.
