Paraseptal structural abnormalities like septal deviation are common but do not increase sinusitis risk in patients without prior sinus disease. Routine rhinoscopy findings do not necessitate further sinus imaging if no sinusitis history exists.

Area of Science:

  • Otolaryngology
  • Radiology
  • Anatomy

Background:

  • Paraseptal structural abnormalities are frequently observed in sinusitis patients.
  • Their direct etiological role in individuals without prior sinus disease remains debated.
  • These anatomical variations may coexist with radiographic sinusitis indicators.

Purpose of the Study:

  • To investigate the correlation between paraseptal anatomical abnormalities and sinusitis in patients with no prior sinus disease history.
  • To determine if septal deviation, concha bullosa, or paradoxical middle turbinates predict sinusitis radiologically.
  • To assess the necessity of further sinus imaging based on these anatomical findings.

Main Methods:

  • Computerized tomographic (CT) scans of the orbits of 89 patients without a history of sinusitis were reviewed.

  • The incidence of septal deviation, concha bullosa, and paradoxical middle turbinates was recorded.
  • The Chi-squared (CM-square) statistical method was employed to analyze the correlation with sinusitis.

    • Main Results:

    • No statistically significant association was found between the presence of septal deviation, concha bullosa, or paradoxical middle turbinates and radiologically confirmed sinusitis.
    • These anatomical abnormalities did not correlate with an increased incidence of sinusitis in the studied cohort.
    • Radiographic evidence of sinusitis was not more prevalent in patients with these structural variations.

    Conclusions:

    • The presence of paraseptal structural abnormalities, such as septal deviation or large middle turbinates, does not independently indicate sinusitis.
    • Routine rhinoscopic findings of these anatomical variations in patients without a sinusitis history do not warrant further radiological evaluation of the sinuses.
    • Further investigation is not recommended solely based on anatomical variations if sinusitis is absent.
