This paper presents the findings of an observational study involving 38 patients to evaluate the application of a surgical technique utilizing an autologous costal cartilage scaffold for correcting nasal tip and alar asymmetry in unilateral cleft lip-nasal deformity. Nasal septum extension spreader grafts (SEG) and warped alar batten grafts, both made from autologous costal cartilage, were utilized in open rhinoplasty procedures. The warped alar batten graft was fixed to the caudal end of the SEG, with the lower lateral cartilage on the cleft side suspended to the free part of the newly created warped alar batten graft to lift the collapsed nasal alar further. Measurements of nasal tip height, nostril height, and the intersection angle of the nasal sill and alar (α) were taken before and after surgery, comparing the ratios between the normal and cleft sides. Patients were followed up for 2.5 to 5.5 years, with all cases showing successful healing and no complications. Postoperative improvements in nasal tip and nostril asymmetries were significant, with statistically significant changes observed in nasal tip height, nostril height, and the intersection angle of nasal sill and alar (α) (P<0.05). The combined use of SEG and warped alar batten graft, both crafted from autologous costal cartilage, effectively corrected nasal tip and alar asymmetry in adult cleft lip nasal deformity cases.
