Abstract:
Objective:To investigate the clinical application of a cartilage graft fixation method in the context of rib-based rhinoplasty.Methods:The clinical data of patients who underwent costal cartilage based rhinoplasty in the Center of Rhinoplasty and Nasal Reconstruction, Plastic Surgery Hospital, Chinese Academy of Medical Sciences from January 2020 to January 2022 were retrospectively analyzed. A 20 ml syringe needle was used to drill several micropores about 1 mm in diameter on the surface of the cartilage grafts prior to its placement. "septal extension grafts with micropores" were prepared, and the preparation of the remaining grafts was conventional.Results:A total of 30 female patients aged 21-45 years, with an average age of 36 years underwent primary or repaired autogenous costal cartilage rhinoplasty without severe damage to the nasal septum cartilage (at least retention of L-shaped scaffolds larger than 10 mm) were enrolled. All operations were successful, the cartilage scaffold was stable and durable. There were no serious complications such as infection, septal hematoma and cartilage exposure. Postoperative patients were followed up for a duration of 6-24 months. Two out of 30 patients were not satisfied with the postoperative appearance. During the revision surgery, the septal perichondrium was separated, mucosal tissue had grown into the bilateral holes which further verified of the feasibility of drilling. The other patients were satisfactied with the results.Conclusion:Nasal septum extension graft based on drilling technique is beneficial to maintain the long-term stability of cartilage scaffold after comprehensive costal cartilage nasal surgery, which justifies its application in comprehensive nasal plastic surgery.
