Background:
Scientific evidence of nonsurgical site-related complications in mandibular fracture patients is limited.
Purpose:
The purpose was to measure the frequency of nonsurgical site complications in patients with mandible fractures, describe the types of complications, and identify the risk factors associated with these complications.
Study Design, Setting, Sample:
A retrospective cohort study was conducted at the Helsinki University hospital between 2018 and 2021. Patients undergoing surgery with open reduction and internal fixation of mandibular fracture(s) were evaluated. Patients under 16 years of age were excluded.
Predictor Variable:
Primary predictor variable was age. Patient-related predictor variables were sex, long-term disease(s), smoking, and alcohol and/or drug abuse. Injury and fracture-related variables were injury mechanism, type and site of facture, combined craniofacial fracture(s), and associated injury(s).
Main Outcome Variable(S):
The primary outcome variable was nonsurgical site-related postoperative complication. The secondary outcome variable was type of complication.
Covariates:
Not applicable.
Analyses:
The main outcome variable was cross tabulated for pairwise comparisons with predictor variables. Multivariate logistic regression was performed for statistically significant (P < .05) variables.
Results:
The data included 314 patients (age range: 16 to 89 years; mean age: 38 years old; median age: 33 years old); most (78.3%) were men. Nonsurgical site-related postoperative complications occurred in 6.7% of patients. The most common complication type was pulmonary complication (36.0%), followed by urinary complication (20.0%) and general infection (16.0%). Nonsurgical site-related postoperative complications were most likely to occur in patients who were elderly (adjusted odds ratio [aOR] 5.55; 95% CI 1.92 to 16.21; P = .002), had combined craniofacial fractures (aOR 2.92; 95% CI 1.06 to 8.03; P = .038), and abused alcohol or drugs (aOR 4.51; 95% CI 1.70 to 11.96; P = .003). Pulmonary complications occurred more often in elderly patients, whereas urinary complications were more common in younger patients.
Conclusions And Relevance:
The types of nonsurgical site complications in mandibular fracture patients increase and vary according to the patient's age. Awareness of possible complications related to different age groups helps anticipate and identify these in clinical work, and to consider the overall treatment of the patient beyond the fracture.
