This study introduces a new virtual technique for analyzing the maxillary sinus (MS) anatomy. The 3D imaging method helps clarify MS morphology and clinical characteristics for better diagnosis and surgical planning.

Area of Science:

  • Anatomy
  • Radiology
  • Oral and Maxillofacial Surgery

Background:

  • Accurate anatomical descriptions of the maxillary sinus are crucial for pathological diagnosis and surgical treatment planning.
  • Existing methods may lack the detail required for comprehensive analysis of maxillary sinus morphology.

Purpose of the Study:

  • To develop and present a novel virtual technique for simulating anatomical structures.
  • To elucidate the morphological and clinical characteristics of the maxillary sinus using 3D imaging.

Main Methods:

  • Utilized 33 hemi-sectioned Korean heads for CT scans and DentaScan imaging.
  • Generated 3D reconstructed images using the V-works program from CT data.
  • Classified maxillary sinus morphology into six categories based on lateral aspects and inferior wall shapes.

Main Results:

  • A flat inferior wall of the maxillary sinus was observed in 55% of specimens.
  • Measurements (length, height, width, volume) of the maxillary sinus were significantly larger in males than in females.
  • The anterior limit of the maxillary sinus was typically in the first premolar area, and the posterior limit was in the third molar/maxillary tuberosity area.

Conclusions:

  • The developed virtual technique allows easy manipulation of 3D reconstructed images on a personal computer.
  • This method facilitates observation of 3D morphology and determination of anatomical characteristics of the maxillary sinus and surrounding structures.
  • The findings provide valuable insights for clinical diagnosis and surgical planning involving the maxillary sinus.
