Summary

Pneumatization of the superior turbinate, an uncommon anatomical variation, was observed in 48% of patients undergoing paranasal sinus CT scans. This finding is crucial for pre-endoscopic sinus surgery evaluations.

Area of Science:

  • Anatomy
  • Radiology
  • Otolaryngology

Background:

  • Anatomical variations in the paranasal sinuses are critical for pre-endoscopic evaluations.
  • Pneumatization of the middle turbinate is a well-documented phenomenon.

Purpose of the Study:

  • To investigate the occurrence and characteristics of superior turbinate pneumatization.
  • To determine if superior turbinates can pneumatize similarly to middle turbinates.

Main Methods:

  • Retrospective analysis of CT scans from 52 patients prior to endoscopic sinus surgery.
  • Evaluation of patients with normally aerated posterior ethmoidal cells and clear nasal cavities.
  • Grading of superior turbinate pneumatization as minimal or marked.

Main Results:

Related Experiment Videos

  • Superior turbinate pneumatization was identified in 25 patients (48%).
  • Minimal pneumatization (unilateral/bilateral) occurred in 38% of patients.
  • Marked pneumatization (unilateral/bilateral) was present in 8% of patients.
  • Aeration of superior turbinates appeared to occur via posterior ethmoid cells.

Conclusions:

  • Superior turbinate pneumatization is a notable, albeit infrequent, anatomical variation.
  • This variation should be considered during pre-endoscopic CT assessments of the paranasal sinuses.
