Appraising Asymmetric Temporal Deformity: A Three-Dimensional Imaging-Based Panel and Morphometric Outcome Study.

Area of Science:

• Neurosurgery
• Plastic Surgery
• Medical Imaging

Background:

• Asymmetric temporal deformity is a frequent complication after craniofacial and neurosurgical procedures.
• Current methods for characterizing temporal asymmetry lack a universal standard.
• Accurate assessment is crucial for patient outcomes and surgical planning.

Purpose of the Study:

• To evaluate subjective perceptions of temporal asymmetry by professionals and laypersons.
• To objectively measure temporal asymmetry using morphometric techniques.
• To determine the correlation between subjective and objective assessments of temporal deformity.

Main Methods:

• A cross-sectional study analyzed 3D craniofacial images from 64 adults post-pretemporal approach surgery.
• Subjective temporal asymmetry was rated using a Likert scale by professionals and laypersons.
• Objective assessment involved morphometric analysis of temporal region volume and contour differences.

Main Results:

• Postoperative temporal asymmetry significantly increased in volume, contour, and subjective scores.
• Perceptions of asymmetry did not significantly differ between professional and lay raters.
• Both groups' ratings showed moderate-to-strong positive correlations with objective volume and contour measures.

Conclusions:

• Subjective perceptions of temporal asymmetry are comparable between professionals and laypersons.
• These perceptions correlate with objective morphometric measures, although the strength of correlation varies.
• Findings highlight the need for standardized objective assessment tools to complement subjective evaluations.
