Summary

This study defines key measurements for masticatory muscles, like the masseter and medial pterygoid muscles, using CT scans. Maximum cross-sectional area (MCSA) is a reliable indicator of muscle volume, aiding facial asymmetry treatment.

Area of Science:

  • Anatomy
  • Medical Imaging
  • Biometrics

Background:

  • Quantitative data on normal masticatory muscle size is limited.
  • Accurate muscle volume assessment is crucial for treating facial asymmetry.

Purpose of the Study:

  • To establish morphological indicators for masticatory muscle volume using CT scans.
  • To correlate maximum cross-sectional area (MCSA) with muscle volume.

Main Methods:

  • CT scans of 65 patients were analyzed.
  • Cross-sectional areas and volumes of masseter and medial pterygoid muscles were measured.
  • Mandibular foramen was used as a landmark for MCSA localization.

Main Results:

  • MCSA of masseter and medial pterygoid muscles strongly correlated with their total volume.

Related Experiment Videos

  • MCSA of masseter muscle was located 8 mm superior to the mandibular foramen.
  • MCSA of medial pterygoid muscle was located at the mandibular foramen.
  • A positive correlation was observed between the volume and MCSA of both muscles.

    • Conclusions:

    • MCSA can serve as a reliable indicator of masticatory muscle volume.
    • Knowing MCSA location can streamline measurements and reduce radiation exposure.
    • Inter-muscle correlations suggest potential for further biomechanical and pathological research.
