Concha bullosa, an aeration of the middle turbinate, is common in patients with sinus disease. While not directly linked to ostiomeatal complex inflammation, large concha bullosa can obstruct sinuses and impact endoscopic surgery.

Area of Science:

  • Otolaryngology
  • Medical Imaging
  • Anatomy

Background:

  • Concha bullosa is a frequent anatomical variation of the middle turbinate.
  • Its prevalence and impact on sinus disease require detailed investigation.

Purpose of the Study:

  • To review the anatomy, pathophysiology, and CT findings of concha bullosa.
  • To assess the relationship between concha bullosa and sinonasal inflammatory disease.

Main Methods:

  • Coronal CT scans of 320 patients evaluated for sinus disease were analyzed.
  • Prevalence of concha bullosa and its association with ostiomeatal complex inflammation were determined.

Main Results:

  • 34% of patients exhibited concha bullosa on at least one side.

Related Experiment Videos

  • No significant difference in ostiomeatal complex inflammation was found between patients with and without concha bullosa.
  • Abnormally large concha bullosa was observed to obstruct the ostiomeatal complex, potentially causing secondary sinusitis and mucocele formation.

    • Conclusions:

    • Concha bullosa is a common finding with significant implications for sinus disease management.
    • While not directly causing inflammation, its size can lead to obstruction and secondary infections.
    • Understanding concha bullosa is crucial for effective endoscopic sinus surgery planning.
