This randomized controlled trial aims to compare the postoperative analgesic efficacy of M-TAPA block and OSTAP block in patients undergoing laparoscopic inguinal hernia repair. Pain scores, analgesic consumption, and patient satisfaction will be evaluated.

Prospective, randomized, single-blind, controlled study including 90 patients undergoing elective laparoscopic inguinal hernia repair. Patients will be randomized into three groups: M-TAPA, OSTAP, and control. Postoperative pain scores (VAS), analgesic consumption, time to first analgesic requirement, and patient satisfaction will be assessed over 24 hours.
