Nasal septum deviation significantly increases the risk and severity of chronic sinus disease and ostiomeatal complex (OMC) obstruction. Understanding septal angulation aids in diagnosing factors contributing to sinus issues.

Area of Science:

  • Otolaryngology
  • Radiology
  • Anatomy

Background:

  • Computerized tomography (CT) has improved understanding of sinonasal pathology.
  • Ostiomeatal complex (OMC) obstruction is a key factor in chronic sinus disease.
  • Nasal septal deviation is a common anatomical variation.

Purpose of the Study:

  • To evaluate the correlation between the degree of nasal septal deviation and the incidence/severity of OMC obstruction and chronic sinus disease.
  • To identify factors contributing to OMC obstruction, both ipsilateral and contralateral to septal deviation.

Main Methods:

  • Prospective evaluation of 150 patients using CT scans.
  • Comparison of patients with varying degrees of nasal septal deviation to matched controls.
  • Correlation of septal deviation with paranasal sinus disease, lateral nasal wall findings, and middle turbinate abnormalities.

Main Results:

  • Increased nasal septal deviation correlated with a higher incidence and severity of bilateral chronic sinus disease (p < 0.05).
  • Patients with greater septal deviation showed a higher incidence of OMC obstruction (p < 0.05).
  • Ipsilateral OMC obstruction was linked to septal deformity, while contralateral obstruction was associated with middle turbinate and lateral nasal wall abnormalities (p < 0.05).

Conclusions:

  • Nasal septal deviation is a significant contributing factor to chronic sinus disease and OMC obstruction.
  • The degree of septal angulation provides insight into the etiology of chronic sinus disease.
  • Understanding these anatomical relationships is crucial for diagnosing and managing sinonasal conditions.
