Abstract: Objective To compare the clinical features and treatment results of multi-space infections of aral and maxillofacial region in patients with or without diabetes. Methods 104 patients with multi-space infections of aral and maxillofacial region treated from January 2014 to October 2017 were retrospectively analyzed. They were divided into diabetic group (n=38) and non-diabetic group (n=66) according to whether they had diabetes or not. The clinical features and treatment results of the 2 groups were compared. Results Compared with non-diabetic group, patients in diabetic group were much older, had much more infection spaces, and their blood glucose and neutrophil counts at admission were much higher; they had much higher detection rate of Klebsiella pneumoniae, their incisions of drainage were much more, hospitalization time was much longer, incidence of complications was much higher. The differences were statistically significant (P＜0.05). The main pathogeny in both groups was odontogenic infection, and there was no significant difference in the infected spaces between the two groups (P＞0.05). Conclusion Diabetic patients with oral and maxillofacial multi-space infections are more serious, showing more infections, more complications, more incisions of drainage, and longer hospitalization.
