Chronic sinusitis severity, measured by CT scans, correlates with the number of bacterial species identified. More bacteria mean higher CT scores, suggesting targeted antibiotic therapy is crucial for advanced cases.

Area of Science:

  • Otolaryngology
  • Radiology
  • Infectious Disease

Background:

  • Chronic sinusitis is a common condition affecting the paranasal sinuses.
  • Inflammatory lesion advancement impacts patient quality of life and treatment outcomes.
  • Accurate diagnosis is essential for effective management.

Purpose of the Study:

  • To investigate the correlation between computed tomography (CT) findings and microbiological results in chronic sinusitis patients.
  • To determine if the extent of sinus inflammation relates to the number and type of microbial pathogens.
  • To inform perioperative treatment strategies based on diagnostic findings.

Main Methods:

  • A study group of 28 chronic sinusitis patients undergoing endoscopic sinus surgery was analyzed.

  • Preoperative sinus CT scans were scored using the Lund-Mackay scale.
  • Bacteriological and mycological examinations of nasal secretions were performed.

    • Main Results:

    • A significant positive correlation was observed between the CT score and the number of bacterial pathogen species (r = 0.46, p = 0.0141).
    • Each additional bacterial species correlated with a 2.3-point increase in CT score.
    • Patients with positive bacterial cultures showed a higher average CT score (4.4 points, p = 0.0333), unlike fungal presence.

    Conclusions:

    • The extent of inflammatory lesions in chronic sinusitis, as assessed by CT, is associated with bacterial load.
    • Microbiological diagnostics are vital for guiding perioperative antimicrobial therapy in advanced sinusitis cases.
    • Fungal presence did not show a similar correlation with CT scores in this study.
