Background: The aim of this retrospective study was to compare the clinical outcomes of total endoscopic transaxillary (TET) breast augmentation with those of non-TET (NTET) breast augmentation. For the purposes of this study, the term NTET refers to the combination of blunt dissection and endoscopic techniques, whereas TET did not involve blunt dissection.
Methods: We conducted a retrospective review of 119 consecutive cases of primary breast augmentation from May 1, 2020, to August 31, 2020. The primary outcomes were the number of drainage days and pain scores as assessed using the visual analog scale on the first postoperative day. The secondary outcomes were the daily drainage volume recorded during the postoperative drainage days, the presence of postoperative daily pain that required the administration of tramadol for relief, reoperation rate, and operative time.
Results: The number of drainage days was significantly lower in the TET group than in the NTET group (TET vs NTET: 2.56 ± 0.57 vs 3.78 ± 1.30 days, P = 0.000). The visual analog scale score on the first postoperative day was significantly lower in the TET group than in the NTET group (TET vs NTET: 4.96 ± 0.63 vs 5.93 ± 0.93, P = 0.000).
Conclusions: We observed that the major outcomes of the TET group were more favorable than those of the NTET group. Based on our results, we recommend the avoidance of blunt dissection during endoscopic transaxillary breast augmentation.
