This clinical retrospective study evaluates whether masseter sarcopenia, measured on routine head CT scans, predicts mortality after Type II odontoid fractures in elderly patients. Using masseter cross-sectional area (MCSA) thresholds, the authors found that lower MCSA is independently associated with increased 1-year mortality, while frailty indices and age drive longer-term risk.
The paper details methods, cohort characteristics (n=72, mean age 80.9), imaging measurement technique, multivariate Cox models, and Kaplan-Meier analyses. Results support MCSA as a practical prognostic marker to inform postinjury management and targeted interventions in high-risk geriatric trauma patients.
