The Efficacy of Superficial Cervical Block Application in Postoperative Analgesia Management in Patients Undergoing Total Laryngectomy and Bilateral Neck Dissection

"Patients in this group will receive a bilateral superficial cervical block under ultrasound guidance after anesthesia induction but before the surgical procedure begins.~The block will be performed using 0.1 mL/kg of 0.25% bupivacaine per side, targeting the superficial branches of the cervical plexus.~The primary goal is to assess its efficacy in postoperative pain management and its impact on recovery parameters."
