How Much Weight Loss Can Be Expected After Treating Mandibular Fractures?

Area of Science:

• Oral and Maxillofacial Surgery
• Trauma Surgery
• Metabolic Response to Injury

Background:

• Mandibular fractures require significant energy for healing, yet treatments often involve dietary restrictions.
• The impact of mandibular fracture treatment on patient weight has been poorly quantified.
• Understanding weight changes is crucial for optimizing patient recovery and outcomes.

Purpose of the Study:

• To quantify the effect of mandibular fractures and their treatment on patient weight.
• To identify risk factors associated with significant weight changes in these patients.
• To investigate the correlation between treatment modalities and weight fluctuations.

Main Methods:

• Retrospective cohort study of 439 patients with mandibular fractures treated between August 2012 and April 2015.
• Analysis included time since presentation, age, gender, open vs. closed treatment, and trauma intensive care unit (TICU) stay.
• Percentage weight change from baseline was the primary outcome, analyzed using a linear mixed model.

Main Results:

• Patients experienced a peak weight loss of 4.9% by day 49.
• Trauma intensive care unit (TICU) stay was significantly associated with increased weight loss (peak 8.8%).
• Open versus closed treatment methods did not show a significant difference in weight change.

Conclusions:

• Mandibular fracture treatment leads to an average weight loss of nearly 5% of body weight.
• While closed reduction did not significantly impact weight, TICU admission was linked to greater weight reduction.
• Further research is needed to correlate weight loss with clinical outcomes in patients with mandibular fractures.
