Ludwig氏氣腫（LA）是一種快速進展的蜂窩組織炎，通常在口腔感染或後磨牙拔除後發展，典型症狀包括發燒和寒顫，很少進展為口咬困難和發紺。與糖尿病、酗酒、口腔惡性腫瘤、口腔牙齒不良或免疫功能受損等危險因素有關。本案報告回顧了一位之前健康、沒有明顯危險因素的患者，在拔除第三磨牙後出現LA，並合併前頸深部膿腫、海綿靜脈血栓形成和Lemierre綜合徵。我們的案例顯示，在懷疑LA時，及早干預非常重要，以防止危及生命的併發症和死亡。© BMJ Publishing Group Limited 2023. 禁止商業再利用。詳情請參閱權益和許可權。由BMJ發表。

Ludwig's angina (LA) is a rapidly progressing cellulitis that develops after oral infections or molar extractions, typically causing fever and chills and rarely progressing to trismus and cyanosis. It is associated with risk factors including diabetes mellitus, heavy alcohol use, oral malignancy, poor dentition or an immunocompromised state. This case report reviews a previously healthy patient with no appreciable risk factors presenting with LA following a third molar extraction, complicated by extensive anterior deep neck space abscesses, cavernous venous thrombosis and Lemierre's Syndrome. Our case demonstrates the importance of early intervention when suspecting LA to prevent life-threatening complications and death.© BMJ Publishing Group Limited 2023. No commercial re-use.
