This prospective interventional study aims to evaluate and compare the analgesic efficacy of the Serratus Posterior Superior Intercostal Plane (SPSIP) block and Rhomboid Intercostal Block in patients undergoing breast cancer surgery with axillary lymph node dissection. The type of regional anesthesia technique will be determined by the attending anesthesiologist based on clinical judgment, without randomization. The primary outcome is postoperative pain intensity assessed by the Visual Analog Scale (VAS) during the first 24 hours after surgery. Secondary outcomes include total opioid consumption, requirement for rescue analgesia, block performance time, block-related and systemic complications (hematoma, pneumothorax, local anesthetic systemic toxicity, vascular puncture, infection), patient satisfaction assessed using a Likert scale, and quality of recovery assessed using the QoR-15 questionnaire.
