Nasal septal deviation and uncinate process orientation correlate with sinus opacification. While statistically significant, these anatomical variations have limited diagnostic value for sinusitis but aid in preoperative planning.

Area of Science:

  • Otolaryngology
  • Radiology
  • Anatomy

Background:

  • The ostiomeatal complex is crucial for sinus drainage.
  • Anatomical variations can predispose individuals to sinusitis.

Purpose of the Study:

  • To evaluate the correlation between nasal septal angulation, uncinate process deviation (U-VS angle), and sinus opacification.
  • To determine the predictive value of these anatomical measurements for maxillary and ethmoid sinusitis.

Main Methods:

  • Prospective CT scan evaluation of 100 consecutive patients.
  • Correlation analysis of nasal septal deviation, U-VS angle, infundibular, and middle meatus opacification with maxillary and ethmoid sinus opacification.

Main Results:

  • Increased nasal septal deviation and horizontal uncinate processes were associated with higher sinus opacification frequencies.

  • Infundibular opacification predicted maxillary sinusitis (76%); middle meatus opacification predicted ethmoid sinusitis (78%).
  • A small, statistically significant decrease in U-VS angle and increase in nasal septal deviation were observed in sinusitis patients.

    • Conclusions:

    • Anatomical variations show a small but significant association with sinusitis.
    • These measurements have limited value in diagnosing sinusitis but are useful for preoperative planning.
