Abstract：
Liposuction is a surgical procedure performed worldwide. Although many fatal complications of liposuction have been reported, to our knowledge, no cases of fatal liposuction complications specifically related to the face region have been reported. Here, we present a case of a woman in her 30s who developed a cervical hematoma and upper airway obstruction following facial liposuction. We present this unique case to highlight the rare occurrence of fatal complications specific to facial liposuction. The patient underwent liposuction during surgery at a cosmetic surgical clinic and awoke from anesthesia after the procedure. Two hours later, she developed a neck swelling and dyspnea. While the anesthesiologist managed her airway, she went into cardiopulmonary arrest. She was then transferred to the emergency room but died on day 7 of hospitalization. The autopsy revealed swelling of the right cheek and mandible, a subcutaneous hematoma in the same area, and laryngeal edema. A damaged facial artery branch was identified, which was consistent with the computed tomography (CT) findings on admission. CT also showed that the hematoma compressed the right internal jugular vein, suggesting that venous outflow impairment caused by the hematoma may have exacerbated the airway obstruction. This case reveals that cervical hematoma caused by facial liposuction can cause fatal upper airway obstruction and the onset of the hematoma may be gradual.
摘要：
吸脂术是全世界进行的外科手术。尽管已经报道了许多致命的吸脂术并发症，根据我们的知识，目前尚无与面部相关的致命性吸脂术并发症的报道.这里,我们介绍了一例30多岁的女性，面部吸脂术后出现宫颈血肿和上呼吸道阻塞。我们提出这个独特的案例来强调面部吸脂术特有的致命并发症的罕见发生。患者在美容外科诊所进行手术期间进行了吸脂术，并在手术后从麻醉中醒来。两小时后,她出现了颈部肿胀和呼吸困难。当麻醉师管理她的气道时，她心肺骤停了.随后，她被转移到急诊室，但在住院的第7天死亡。尸检显示右脸颊和下颌骨肿胀，同一区域的皮下血肿,喉头水肿.发现了受损的面部动脉分支，这与入院时的计算机断层扫描（CT）结果一致。CT还显示血肿压迫右颈内静脉,提示血肿引起的静脉流出道损害可能加剧了气道阻塞。该病例显示，面部吸脂术引起的宫颈血肿可导致致命的上呼吸道阻塞，血肿的发作可能是渐进的。
