Clinical features of patients of different ages with postoperative multi-space maxillofacial infection.

To investigate the clinical features of patients of different ages with multi-space infection after maxillofacial surgery. Three hundred and seven patients with infections in multiple spaces were enrolled in the study. They were classified into the senior (n = 149) and the younger group (n = 158). The clinic data were retrospectively analyzed. Male patients accounted for 63.09 and 63.29 % of the senior and the younger group, respectively. Sex composition between the two groups was not significantly different (p > 0.05). Senior patients were associated with significantly more complications than the younger adults (p < 0.05). 46.31 and 55.70 % of patients in the respective two groups had infections involving more than two spaces. Patients in both groups visited the hospital at a similar time after the symptoms manifested (p > 0.05). Elderly patients had similar glucose levels, white blood cell counts and neutrophil cell counts compared to those of the younger groups (p > 0.05). 55.06 % of the younger patients had negative bacterial culture results, which was significantly more than those of the senior groups (p < 0.05). The bacterial compositions of the infection of two groups were also found significantly different (p < 0.05). In the event of postoperative multi-space maxillofacial infection, senior patients shared many similar clinical features with the younger adults. But they also had unique features, such as more complications. As a result, it is more difficult to treat senior patients with multi-space infections. Therefore, more medical attention is required to senior patients.
