Abstract：
The \"double tongue sign\" is a characteristic finding in patients with Ludwig\'s angina, a potentially life-threatening infection due to airway compromise. Management primarily focuses on early airway protection and antibiotic administration. Submandibular sialolithiasis, on the other hand, could present with the double tongue sign without symptoms suggestive of airway involvement. Unlike Ludwig\'s angina, conservative treatment is usually the first-line approach for sialolithiasis. The importance of rapidly recognizing and distinguishing between the 2 conditions is emphasized through effective triage and risk stratification, particularly in rural areas where physicians are not readily available.
摘要：
“双舌征”是路德维希心绞痛患者的特征性发现，由于气道受损而可能危及生命的感染。管理主要集中在早期气道保护和抗生素管理。颌下唾液管结石,另一方面,可能出现双舌征，没有提示气道受累的症状。不像路德维希的心绞痛,保守治疗通常是胆管结石的一线治疗方法.通过有效的分诊和风险分层强调快速识别和区分这两种情况的重要性，特别是在农村地区，医生是不容易得到。
