The Radix Suture: A Strategy for Prevention of Soft Tissue Fullness After Radix Reduction in Rhinoplasty

Area of Science:

• Plastic Surgery
• Facial Aesthetic Surgery
• Rhinoplasty Techniques

Background:

• Rhinoplasty outcomes depend on both the skeletal framework and the skin-soft tissue envelope (SSTE).
• Postoperative changes in the SSTE, such as fibrosis and thickening, can negatively impact aesthetic results, particularly after radix reduction.
• Existing techniques inadequately address preventing secondary increases in radix height and width.

Purpose of the Study:

• To introduce and evaluate a novel transosseous radix fixation suture technique.
• To assess the efficacy of this technique in preventing postoperative radix height increase following dorsal hump reduction with radix lowering.

Main Methods:

• A novel transosseous radix fixation suture was developed, involving a transosseous tunnel and absorbable suture.
• The suture reapproximates the SSTE to deeper tissues, reducing dead space.
• The technique was applied to 30 patients and compared to a control group.

Main Results:

• The radix-suture group showed a significantly smaller change in the nasofrontal angle (NFA) at 12 months compared to controls (4.0° vs. 6.2°, p=0.02).
• Patient-reported satisfaction was higher in the radix-suture group (94% vs. 90%).

Conclusions:

• The novel transosseous radix fixation suture is effective in preventing postoperative radix height increase after rhinoplasty.
• This technique improves aesthetic stability and patient satisfaction by optimizing SSTE redraping.
