Both superficial and deep serratus anterior plane (SAP) blocks are effective for anterior chest wall surgeries, but there is little clarity on which is more effective. Hence, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the comparative efficacy of the 2 approaches for SAP block after anterior chest wall surgery. ⋯ Current evidence does not support the preference for one approach of SAP block over the other for postoperative pain. Based on the available data, we recommend further future trials to determine any differences between these interventions.
