Abstract: Purpose: Laparoscopic cholecystectomy (LC) is a minimally invasive surgical procedure offering reduced postoperative pain, shorter hospital stays, and faster recovery. Despite these benefits, pain from tissue trauma, pneumoperitoneum, and gallbladder removal remains significant. This study compares the analgesic efficacy of the Modified Thoracoabdominal Nerve Block via Perichondrial Approach (M-TAPA) and intraperitoneal bupivacaine with or without dexmedetomidine in patients undergoing LC. Materials and Methods: This prospective, randomized, single-blind trial included 60 ASA I/II patients undergoing elective LC under general anesthesia. Patients were divided into three groups: M-TAPA block (Group M), intraperitoneal bupivacaine (Group B), and intraperitoneal bupivacaine plus dexmedetomidine (Group BD). Postoperative pain was assessed using the Numeric Rating Scale (NRS) at six-hour intervals for 24 hours. Secondary outcomes included rescue analgesic requirements and side effects. Data were analyzed using ANOVA, Kruskal-Wallis, and Bonferroni post hoc tests. Results: Group BD and Group M showed significantly lower NRS scores compared to Group B (p
