Nasal Reconstruction in Granulomatosis with Polyangiitis Using an L-shaped Cartilage Strut Graft.

[METHODOLOGY] Patients exhibited progressive saddle nose deformity as a result of GPA. To reconstruct the nose, a single-stage open rhinoplasty was conducted involving the placement of an independent L-shaped costal cartilage implant. Graft formation and fixation were performed according to the author-developed method.

[RESULTS] From 2012 to 2023, seven patients with severe saddle nose deformity underwent implantation of modified L-shaped costal cartilage strut grafts. Except for one complicated case, all patients reported satisfaction with the surgical outcomes.

[CONCLUSIONS] In this study, the visual appeal of the nose and the respiratory capabilities of the patients improved significantly. The L-shaped costal cartilage strut graft is an effective technique for saddle nose deformity correction. This technique provides excellent outcomes, including improved nasal function and aesthetics. Further studies with a larger sample size are needed to confirm these findings.
