Temporal Muscle Thickness Is a Prognostic Factor for Neurological Recovery After Surgery for Chronic Subdural...

Area of Science:

• Neurosurgery
• Radiology
• Geriatrics
• Sarcopenia Research

Background:

• Sarcopenia is an emerging prognostic factor in surgical patients.
• Chronic subdural hematoma (CSDH) surgery outcomes require better predictive markers.
• Cranial CT scans offer potential for sarcopenia assessment.

Purpose of the Study:

• To evaluate the association between cranial CT-based sarcopenia markers and neurological outcomes in CSDH surgery patients.
• To identify reliable imaging biomarkers for predicting recovery after CSDH surgery.
• To assess the utility of temporal muscle thickness as a predictor of neurological recovery.

Main Methods:

• Retrospective case-control study of 82 CSDH surgery patients.
• Preoperative CT scans analyzed for temporal muscle thickness, area, and occipital fat pad thickness.
• Neurological outcome assessed at 3 months using the Glasgow Outcome Scale.

Main Results:

• Greater temporal muscle thickness, area, and occipital fat pad thickness correlated with favorable neurological outcomes.
• Temporal muscle thickness was the sole independent predictor of good neurological recovery (OR 3.20, p=0.007) after adjustments.
• Temporal muscle thickness (cut-off ≥3.37 mm) demonstrated strong discriminatory power (AUC 0.812) for predicting favorable outcomes.

Conclusions:

• Temporal muscle thickness is a reliable, non-invasive imaging biomarker for predicting good neurological recovery after CSDH surgery.
• This CT-based marker can aid in risk stratification, especially for elderly or frail patients.
• Further research can integrate sarcopenia assessment into routine CSDH patient evaluation.
