Rhinoplasty with Mortise-Tenon Cartilaginous Framework for Caudal Septal Cartilage Defects.

Correcting caudal septal cartilage defects during rhinoplasty remains a clinical challenge due to the difficulty in securing graft fixation. Prior research has shown that graft stability is essential for long-term aesthetic success. However, no prior work had resolved the issue of graft fixation in this specific anatomical region. Established techniques often rely on suture-based methods or composite grafts, which may not provide sufficient structural support. This gap motivated the development of alternative fixation strategies. The need for a more reliable method became evident as complications such as graft displacement or asymmetry were reported in some cases. No prior work had tested a mortise-tenon approach for this application. This uncertainty drove the exploration of a novel cartilaginous framework design.

The aim of this study was to evaluate the feasibility and effectiveness of a mortise-tenon cartilaginous framework in correcting caudal septal cartilage defects during rhinoplasty. The specific problem addressed was the lack of secure graft fixation in this anatomical region. The motivation stemmed from the limitations of existing fixation methods, which may not provide long-term stability. The study sought to introduce a new surgical approach using costal cartilage. The mortise-tenon design was proposed as a solution to improve graft integration and reduce complications. The senior surgeon's experience was leveraged to ensure consistent technique application. The study aimed to assess both aesthetic and functional outcomes. The researchers propose that this method may offer a more stable alternative to traditional grafting techniques.

The study employed a retrospective analysis of patients who underwent rhinoplasty for caudal septal cartilage defects. The mortise-tenon cartilaginous framework was constructed using costal cartilage. The surgical technique involved shaping the graft to fit the defect site precisely. A senior surgeon performed all procedures to maintain consistency. Preoperative and postoperative evaluations were conducted to assess outcomes. The study included 17 patients aged between 27 and 58 years. Follow-up averaged 22.4 months to monitor long-term results. Complication rates and aesthetic satisfaction scores were recorded as primary outcomes.

The study reported no short-term or long-term complications following the procedure. Aesthetic outcomes were satisfactory in all 17 cases. The mean patient-reported improvement score was 8.11 on a 10-point scale. The mortise-tenon framework demonstrated effective graft fixation. No displacement or asymmetry was observed in postoperative assessments. The use of costal cartilage provided sufficient structural support. The senior surgeon's technique ensured consistent results across all patients. The researchers propose that this method may be more reliable than conventional grafting techniques.

The authors suggest that the mortise-tenon cartilaginous framework is a feasible and effective solution for caudal septal cartilage defects. The study supports the use of costal cartilage in this application. The absence of complications indicates the safety of the technique. The high aesthetic satisfaction score suggests positive patient outcomes. The researchers propose that this method may improve graft stability compared to traditional approaches. The senior surgeon's experience contributed to consistent results. The study does not claim this is the only effective method but suggests it is a viable option. The authors suggest further research to compare this technique with existing methods.
