Background: Ultrasonic scalpel has been reported to be superior to conventional electrocautery in many studies. However, with respect to transaxillary endoscopic breast augmentation, few studies on the effect of ultrasonic scalpel are available in the literature.
Methods: The medical records of 173 female patients who underwent breast augmentation via endoscopic transaxillary approach from January 2018 to December 2020 were reviewed retrospectively. The patients were divided into two groups according to the implant pocket dissection instruments. In group A, the implant pockets were dissected with conventional electrocautery (EC group) on 81 patients, and in group B, ultrasonic scalpel (US group) was used for implant pockets on 92 patients. All operations were performed by the same senior plastic surgeon and the same surgical team. The operation time, intraoperative blood loss, postoperative total drainage volume, days of drainage, postoperative surgical site pain and hospital stay time of the two groups were compared and analyzed statistically.
Results: The average operation time of the US group (83.82 ± 11.57 min) was significantly shorter than that of the EC group (101.40 ± 14.36 min), intraoperative blood loss in the US group was significantly less than that of the EC group (18.67 ± 6.20 ml vs. 21.59 ± 6.44 ml), the mean hospital stay days (2.96 ± 0.69 vs. 4.30 ± 1.11), total drainage volume (122.24 ± 43.81 vs. 232.37 ± 99.15), and duration of drain (2.52 ± 0.54 vs. 3.77 ± 1.10), mean VAS score for surgical site pain on 3 postoperative days (5.08 ± 1.35 vs. 6.51 ± 1.36, 4.08 ± 1.16 vs. 5.40 ± 1.32, 3.04 ± 0.91 vs. 4.06 ± 1.11) were significantly lower in the US group compared to the EC group.
Conclusions: The ultrasonic scalpel reduces operative time, intraoperative blood loss, postoperative drainage, postoperative pain, hospital stay time, and incidence of complications. The ultrasonic scalpel is safe and reliable for transaxillary endoscopic breast augmentation.
