This approach aims to ensure the maximal survival of the fat graft with reduced fat necrosis and long-term asymmetry, producing sustained results over time.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Measurement of pectoralis major pressure after fat grafting was conducted in 150 patients (19-60 years old; BMI &amp;lt; 30\u2005kg\/m2) between January 2021 and June 2023.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The 2 models used in this study exhibited strong explanatory power, indicating that a significant portion of the variability in fat graft resorption could be explained by the variables included in these models. Postoperative exercise, patient age, and intramuscular pressure of the transferred fat showed statistically significant correlation with fat graft survival. BMI did not show a statistically significant relationship. The established volumes did not exceed 8\u2005mm Hg intracompartmental pressure. Higher volumes reduced fat survival. Large volumes led to greater postoperative asymmetry and loss of fat grafts.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n
