Abstract
Oral and maxillofacial space infection (OMSI) progresses rapidly, and when combined with diabetic ketoacidosis (DKA), it can become a serious and life-threatening condition. Cases of OMSI with concurrent DKA are relatively rare. This case report describes a young man who developed OMSI caused by methicillin-resistant Staphylococcus aureus in the setting of DKA. A 21-year-old man presented with swelling and pain in the right lower lip that had persisted for four days; the symptoms were both atypical and severe. Based on the patient's clinical course, hyperglycemia may play an important role in the onset and progression of OMSI in young individuals. It is essential to identify the underlying cause of OMSI and to closely monitor clinical signs for timely intervention.
