Abstract

Background: Cartilage warping has plagued reconstructive and cosmetic rhinoplasty since the introduction of extraanatomical cartilage use. The authors' group theorized that, rather than focusing on the prevention of the innate tendency of rib graft warping, it may be possible to redirect the stressors toward themselves and use these forces with oppositional suturing techniques to compensate for these intrinsic characteristics. Methods: Fresh cadaver cartilage was obtained from the costosternal junction of two rib cages (aged 77 and 99 years). The cartilage was cut manually into 4 × 2.5 × 20-mm cross-sections from the cephalic edges of each of the harvested specimens. The specimens from the right chest were used as the control and the left segments underwent an oppositional suturing technique (n = 10) of the cephalic peripheral segment of the cartilage. Results: Overall, the control group experienced a 724.2 percent increase in the mean degree of warping (p <0.001). In contrast, the oppositional suturing group experienced a mean decrease in warping angle relative to baseline of only 35.7 percent. At 1 month, the oppositional suturing group displayed significantly decreased warping compared with the control group. Conclusions: This is a novel cadaveric study evaluating the benefit of oppositional suturing techniques in peripheral costal cartilage grafts. Multiple techniques and maneuvers have been borne out of the frustration of these inherent characteristics of costal cartilage grafts. Oppositional suturing techniques are a useful tool available to surgeons performing nasal reconstruction and revision rhinoplasty to maximize the amount of useful costal cartilage graft.
