Analgesic Efficacy of Modified Thoracoabdominal Nerve Block Through Perichondrial Approach After Postbariatric Mammoplasty and Abdominoplasty: A Case Report

A 22-year-old female patient, who had lost 44 kg after sleeve gastrectomy, underwent combined mammoplasty and abdominoplasty for postbariatric skin redundancy. Bilateral modified thoracoabdominal nerve block through perichondrial approach (M-TAPA) was performed for perioperative analgesia. The 250-minute surgery was completed without additional analgesics. Postoperative pain scores (Numerical Rating Scale [NRS] ≤3) remained low, no opioids were required, and no complications were observed. The Quality of Recovery-15 (QoR-15) score at 24 hours was 143. This case may suggest that the M-TAPA block is a safe and effective analgesic option in extensive aesthetic surgeries involving both thoracic and abdominal regions.
