Computed tomography (CT) effectively creates custom nasal septal buttons for patients with large septal perforations. These custom buttons significantly improve symptoms like breathing difficulties, nosebleeds, and crusting, with high long-term retention rates.

Area of Science:

  • Otolaryngology
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Symptomatic septal perforations can cause significant nasal dysfunction.
  • Traditional management may not adequately address large perforations.
  • Custom-fabricated devices offer a potential solution for complex anatomical defects.

Purpose of the Study:

  • To evaluate the efficacy of custom nasal septal buttons created using computed tomography (CT).
  • To assess symptom relief and device durability in patients with septal perforations.

Main Methods:

  • Retrospective chart review and telephone follow-up of 95 patients.
  • Custom Silastic septal buttons fashioned from reformatted CT images.
  • Evaluation of symptom resolution, button-related issues, and retention duration.

Main Results:

  • Average perforation size was 2.6 cm.
  • 86% of buttons remained in place for over 5 years (excluding intolerance removals).
  • Significant symptom improvement: 60% better breathing, 77% reduced epistaxis, 59% reduced crusting.

Conclusions:

  • Custom septal buttons fabricated with CT imaging are effective for large septal perforations.
  • The technique provides durable symptom relief and good device retention.
  • CT-guided custom button creation is a viable treatment option for complex septal defects.
