A unique regional anaesthetic method that is becoming more important for postoperative pain management is erector spinea plane block (ESP). Since its initial description, physicians have questioned weather this novel easy method can take the place of paravertebral block (PVB). Our goal was to evaluate, in contrast to control group, the effects of ESP &amp; PVB on acute and chronic post-mastectomy pain.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>One hundred and five female patients undergoing modified radical mastectomy participated in this study, randomly allocated into three equal groups: erector spinae plane block (ESP), thoracic paravertebral (TPV), and control groups. Both blocks were ultrasound-guided with 20\u00a0ml 0.25% bupivacaine according to patients\u2019 group, control group was administered standard general anaesthesia without intervention. Total morphine consumption in the first 24\u00a0h postoperative was the primary outcome. The secondary outcomes were time to the first analgesia, (Visual Analogue Scale)VAS score, serum level of cortisol and prolactin, sedation score, side effects, and LANSS scores in the first, third, and sixth postoperative months were among the variables compared between groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Total morphine consumption in the first 24\u00a0h was significantly higher in control than ESP and TPV groups (10.74\u2009\u00b1\u20091.37, 8.17\u2009\u00b1\u20091.69, 5.70\u2009\u00b1\u20091.95 respectively\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
