Abstract

 Background: Closed rhinoplasty is a technically challenging procedure due to the limited access to underlying anatomical structures, requiring substantial surgical experience. However, it offers the advantages of minimal external scarring and a significantly shorter recovery time compared to open rhinoplasty. Objectives: To evaluate the outcomes and complications of closed rhinoplasty using auricular cartilage and synthetic materials. Materials and methods: A case series of 44 patients who underwent closed rhinoplasty with septal extension grafts made of polycaprolactone and auricular cartilage at 7A Military Hospital between April 2024 and February 2025 was analyzed. Results: The majority of patients were female, with a mean age of 22 ± 4.5 years. The mean operative time was 130 ± 25 minutes; 78% were primary surgeries and 22% were revision procedures. Postoperatively, patients demonstrated significant improvement in nasal anthropometric parameters. Mild incision erythema occurred in 11% of cases, and 11% reported temporary nasal obstruction that was completely resolved within two weeks. No cases of infection, implant extrusion, nasal deviation, necrosis, or columellar retraction were observed. All patients achieved good wound healing; 13.6% had faint scars on the nasal vestibular mucosa, and no visible columellar scars were detected. Patient satisfaction was high, with 84% reporting being very satisfied, 16% satisfied, and none dissatisfied with the surgical outcomes. Conclusion: Closed rhinoplasty using auricular cartilage and synthetic materials can be effectively applied in both primary and revision procedures. The postoperative course is smooth with minimal complications, and the technique provides excellent aesthetic results without columellar scarring, achieving high patient satisfaction.
