Vibration amplification of sound energy at resonance (VASER®) is a third-generation internal ultrasonic liposuction technology. VASER® is less likely to damage blood vessels, nerves, or other tissues; thus, it is less stressful for the body because of reduced blood loss. Herein, we report a case of a 23-year-old woman who developed a serious complication due to bleeding after liposuction of the face line using VASER® technology at a nearby cosmetic surgery clinic. After returning home, the patient experienced dyspnea and was brought to the emergency department. Upon arrival, neck swelling and hematoma were observed. Emergency tracheal intubation and hematoma removal were performed. The patient was treated by members of the emergency, otolaryngology, anesthesiology, and plastic surgery departments. The patient survived.
VASER® offers advantages such as reduced bleeding and safer surgical techniques. However, careful management of perioperative blood pressure and pain, as well as thorough postoperative compression, are essential to prevent hematoma formation.
