After genioplasty, the occurrence of bleeding is rare; however, rapid enlargement or displacement of the tongue secondary to lingual or sublingual hematoma can lead to life-threatening airway obstruction, necessitating prompt recognition, and immediate management. Therefore, the investigators aimed to evaluate the underlying etiologies of sublingual hematoma and relevant anatomy to facilitate early recognition of the initial presentation of these hematomas and appropriate management. The authors conducted a literature review on cases of delayed sublingual hematoma after genioplasty. The authors also report a case of delayed hematoma after performing genioplasty. The anatomical structures involved with the development of rare and serious hematomas therein are the sublingual and submental arteries, which are located in the sublingual area, rendering them susceptible to injury during genioplasty. The results of this study suggest that submental artery ligation should be performed for proper management of airway obstruction, if symptoms of sublingual bleeding are observed during the surgical procedure. If there is continuous bleeding despite the submental artery ligation, sublingual artery ligation should be performed.
颏成形术后很少发生出血；然而，舌或舌下血肿会导致舌迅速肿大或移位，从而导致危及生命的气道阻塞，需要及时识别和立即处理。因此，研究人员旨在评估舌下血肿的潜在病因和相关解剖结构，以便及早识别这些血肿的初始表现并进行适当的处理。作者对颏成形术后迟发性舌下血肿的病例进行了文献回顾。作者还报告了一例颏成形术后迟发性血肿的病例。在发生罕见和严重血肿的解剖结构是舌下动脉和颏下动脉，它们位于舌下区域，使得它们在颏成形术中容易受伤。本研究结果表明，如果在手术过程中观察到舌下出血症状，应进行颏下动脉结扎以适当处理气道阻塞。如果尽管进行了颏下动脉结扎仍持续出血，应进行舌下动脉结扎。
