Summary

Septal obturators offer an alternative for nasal septal perforations when surgery is not possible. Digital CT scans provide measurements comparable to traditional silicone impressions, especially for larger defects.

Area of Science:

  • Otolaryngology
  • Medical Imaging

Background:

  • Symptomatic nasal septal perforations significantly impact quality of life.
  • Septum obturators are a viable alternative when surgical closure is contraindicated or impossible.
  • Accurate defect assessment is crucial for effective obturator fitting.

Purpose of the Study:

  • To compare the accuracy of digital computed tomography (CT) scans versus traditional silicone impressions for assessing nasal septal perforation (NSD) anatomy.
  • To evaluate the reliability of CT-based measurements for custom obturator fabrication.

Main Methods:

  • Retrospective analysis of 500 patients with septal perforations.
  • Detailed comparison of defect size and shape measurements from silicone impressions and preoperative CT scans in 19 patients.
  • Conversion of silicone impressions to plaster models, then digital scanning; CT data converted to 3D models for precise comparison.

Main Results:

  • Measurements of nasal septal defect (NSD) size showed deviations less than 10% in 8/19 patients and less than 20% in 13/19 patients.
  • Deviations were smaller for larger defects and when CT scans were performed closer in time to the silicone impression.
  • CT-based measurements demonstrated comparable results to silicone impressions, particularly for larger defects and with close temporal proximity.

Conclusions:

  • Preoperative CT scans provide reliable measurements for nasal septal perforation assessment, comparable to traditional silicone impressions.
  • CT-based measurements are particularly accurate for larger defects and when scans are acquired promptly after impression.
  • Further clinical studies are warranted to assess patient acceptance of obturators fabricated using CT data.
