Prevalence and Risk Factors for Chronic Maxillary Sinusitis After Surgery for Mid-Facial Fracture: A Cross-Sectional Study

Posttraumatic chronic maxillary sinusitis deleteriously affects the life quality of patients with recurrent episodes and related discomfort. However, few studies have been performed to investigate the prevalence of chronic maxillary sinusitis after surgery of mid-facial fracture and related risk factors. The early prevention and cure of posttraumatic chronic maxillary sinusitis have received little attention. This study aimed to investigate the prevalence of chronic maxillary sinusitis after surgery for mid-facial fracture and to identify related risk factors. The authors retrospectively collected the medical history, radiographic examination, and clinical examination of patients with mid-facial fracture (experimental group) and patients with mandibular cyst (control group) in our department between January 2015 and December 2020. A total of 298 patients (416 maxillary sinuses) in the experimental group and 172 patients (344 maxillary sinuses) in the control group were included for analyses. The prevalence of chronic maxillary sinusitis in the experimental group and control group were, respectively, 9.14% and 2.04% (P < 0.05). History of sinusitis/rhinitis (odds ratio = 63.70, P = 0.000) was an independent risk factor for posttraumatic chronic maxillary sinusitis. In conclusion, these findings showed that the prevalence of chronic maxillary sinusitis after surgery for midfacial fracture was significantly higher than that in the control group and long-term follow-up may be beneficial for these patients. Moreover, patients with a history of sinusitis/rhinitis should be informed of the increased risk.

Automated summary

This study investigated the prevalence of chronic maxillary sinusitis after surgery for mid-facial fracture and identified related risk factors. The findings showed that the prevalence of chronic maxillary sinusitis after surgery was significantly higher than the control group, and a history of sinusitis/rhinitis was an independent risk factor.
