Acute upper airway obstruction caused by mouth floor cellulitis in a patient of advanced age: a case report and literature review

Abstract

Mouth floor cellulitis is a type of diffuse cellulitis involving the submandibular, submental, and sublingual spaces. This condition may cause asphyxia due to elevation and posterior deviation of the tissues of the floor of the mouth. The severity of submandibular gland infection often escalates in the presence of underlying comorbidities. Advanced age, hyperglycemia, and an immunocompromised status often lead to the rapid development of infection, resulting in complications such as acute upper airway obstruction. These complications increase treatment difficulty and the risk of mortality. We herein report a case involving an older adult with diabetes who developed mouth floor cellulitis secondary to a submandibular gland infection. Despite the severity of the submandibular gland infection, a timely, effective, and multidisciplinary approach improved the patient’s prognosis.
