Introduction
Nasal septal perforations can cause significant discomfort, including crusting, nosebleeds, and difficulty breathing. Surgical closure remains a challenging option, particularly for large or irregular defects. However, a recent study highlights the use of computed tomography (CT) to create custom nasal septal buttons as a minimally invasive and effective alternative.
This technique addresses the limitations of prefabricated buttons by tailoring the design to each patient’s unique anatomy, providing superior symptom relief with minimal complications.
How CT Imaging Revolutionises Custom Septal Buttons
Custom septal buttons serve as an excellent alternative for patients unsuitable for surgery or those with perforations too large for standard prefabricated buttons. CT imaging enhances this process in several ways:
Improved Comfort: Tailored flanges align with the patient’s nasal anatomy, ensuring a secure and comfortable fit that minimises foreign body sensations.
Precise Sizing: CT scans provide highly detailed images of the perforation and surrounding nasal anatomy, enabling precise measurement and customisation.
Adaptability for Larger Defects: Unlike traditional prefabricated buttons, CT-generated designs can fit perforations up to 6 cm in diameter, addressing even the most complex cases.
Methodology
- CT Evaluation:
- Patients undergo a non-contrast CT scan with 1-mm axial slices, capturing the perforation and surrounding tissues. Reformatted sagittal and coronal images are used to trace the defect.
- Button Carving:
- Using medical-grade silicone, a custom button is carved based on CT measurements. Flanges are designed to adhere securely to the tissue surrounding the perforation.
- Button Placement:
- Buttons are inserted under local or general anaesthesia. Proper positioning ensures maximum symptom relief, and adjustments can be made during the procedure to refine the fit.
Results and Effectiveness
Success Rates: In a study of 95 patients, 86% retained their buttons for more than five years or until the last follow-up.
Symptom Relief:
- Crusting reduced in 59% of cases.
- Epistaxis (nosebleeds) improved in 77%.
- Breathing difficulties eased in 60%.
Durability: While some buttons were replaced after five years, most maintained functionality far beyond their expected lifespan.
Why Choose Custom CT-Guided Buttons
Benefits:
- Non-invasive and reversible, allowing for future surgical repair if needed.
- Superior fit for larger or irregular perforations.
- Immediate symptom relief without the extended recovery associated with surgery.
This method is particularly effective for patients who cannot undergo surgery or prefer a less invasive option.
Conclusion
The use of CT imaging to create custom nasal septal buttons represents a significant advancement in managing septal perforations. By providing a tailored solution with minimal complications, this technique ensures lasting comfort and improved quality of life for patients.
