Abstract

Diced costal cartilage wrapped in autogenous fascia are favored by rhinoplasty surgeons because of their high stability and low resorption rate. However, the volume of fascial bags is difficult to adjust, and diced costal cartilage is prone to undernourished.
To investigate the clinical effect, long-term absorption rate and patient satisfaction of filling nasal dorsum with autogenous diced costal cartilage semi-wrapped in autogenous rectus abdominis fascia.
From May 2020 to December 2022, a total of 95 patients with costal cartilage nasal repair were enrolled in this study. After constructing a nasal tip scaffold with costal cartilage, the autologous rectus abdominal fascia was introduced into the stripped dorsal nasal space and fixed at the golden point of the nasal root. The prepared autologous diced costal cartilage were injected into the dorsal nasal space, and shaped according to the height and curvature of the preoperative design.
During the follow-up of 18 to 24 months, the morphology was satisfactory, the bilateral transition was natural and smooth, and there was no graininess at the back of the nose. Four cases had slight depression in the nasal tip turning area more than half a year after operation. The absorption rate of the graft was about 10%.
Autogenous diced costal cartilage semi-wrapped in autogenous rectus abdominis fascia have low absorption, relatively natural postoperative effect and high patient satisfaction as nasal dorsum filler. They may be particularly suitable for those who repair nose after infection, take nasal dorsal bone powder, and have thinning, redness and light transmission after thread carving.
