However, postoperative circumferential and volumetric changes, and their potential role in complications such as excessive phallic turgor, remain poorly characterized.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aim<\/jats:title>\n                    <jats:p>To quantify early postoperative circumferential and volumetric changes following RFFF phalloplasty in patients with an uneventful postoperative course.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A consecutive series of trans men who underwent RFFF phalloplasty between 04\/2024 and 07\/2025 were analyzed. Phallic circumference was measured intraoperatively and on postoperative days (PODs) 1, 3, 5, 10, and 14 at three levels (base, midshaft, tip). Volumes were modeled from these measurements using geometric formulas (two-frustum method). Patients requiring emergent reintervention (eg, operative revision) were excluded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Outcomes<\/jats:title>\n                    <jats:p>Primary outcomes were temporal changes in circumference and estimated volume relative to intraoperative values within 14\u00a0days.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Twenty-two patients with a mean age of 32\u00a0years (SD 11) met inclusion criteria. Mean flap length was 12.3\u00a0cm (SD 0.9). In most patients (54.5%) three venous anastomoses were performed. Phallic circumference increased most prominently within the first 24\u00a0h and peaked at POD 3, with mean increases of 6.2\u00a0mm at the base, 8.1\u00a0mm at the midshaft, and 7.5\u00a0mm at the tip compared with intraoperative values. Circumferences then declined gradually but remained above baseline on POD 14 (residual mean increase: 3.7\u00a0mm at the base, 4.8\u00a0mm at the midshaft, and 5.3\u00a0mm at the tip). Estimated phallic volume rose from a mean of 111.3\u00a0cm3 (SD 21.7) intraoperatively to 131.2\u00a0cm3 (SD 24.5) on POD 3, before declining to a mean volume of 120.8\u00a0cm3 (SD 21.3) by POD 14. These changes corresponded to a mean relative increase of 16.0 % (SD 15.9) on POD 1 and 19.0 % (SD 15.9) on POD 3. Persistent edema was present in 81.8% of patients at POD 14.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Implications<\/jats:title>\n                    <jats:p>Vigilant monitoring during the first 72\u00a0h is critical for timely decompression.
