Objective: To determine how storage medium and temperature affect the histological viability of autologous septal cartilage intended for early revision rhinoplasty. Methods: Cartilage specimens stored for 6 and 12 months in four media—dry, gentamicin, cefazolin, and saline—at two distinct temperatures underwent histopathological evaluation after paraffin embedding. The assessed parameters were graft viability, fibrosis, osteoid metaplasia, and peripheral chondroid proliferation. Results: Among 480 septal cartilage specimens harvested from 30 patients, overall viability fell from 62 ± 15% at 6 months to 44 ± 14% at 12 months (p < 0.001), while fibrosis, osteoid metaplasia, and peripheral chondroid proliferation all increased significantly (each p < 0.001). Viability declined in every storage condition, but grafts kept at − 80 °C or in saline-based solutions deteriorated fastest, reaching a mean viability of 39% versus 53% for dry storage at − 20 °C at 12 months. Multivariate analysis confirmed − 80 °C storage (OR 2.3, 95% CI 1.4–3.8) and saline media (OR 1.9, 1.1–3.4) as independent predictors of poor viability (< 40%), whereas antibiotic additives were not protective. Histological evidence of osteoid metaplasia (OR 3.6, 1.9–6.8) and peripheral chondroid proliferation (OR 2.1, 1.2–3.7) strongly predicted non-viable grafts. A linear mixed-effects model demonstrated additive negative effects of − 80 °C and saline on both baseline viability and its rate of decline (marginal R² = 0.52). Dry storage at − 20 °C yielded the most favorable long-term viability. Conclusion: Dry storage of autologous septal cartilage at − 20 °C preserves graft viability well enough to offer a cost-effective alternative for early revision surgeries, warranting confirmation in prospective clinical trials.

Objective: To measure the success of the fascia lata-fat island graft technique in septal perforation repair as measured by nasal endoscopic examination. Background: This study presents the results of using fascia lata-fat island, a different graft technique, for the repair of septal perforations, offering an alternative to this challenging procedure. Methods: This retrospective study assesses nasal septal perforation repair using the fascia lata-fat island graft technique performed by a single surgeon. Inclusion criteria involved completing 12-month follow-ups within a 3-year review period. Success rates were calculated and evaluated alongside patient characteristics. Results: The median (range) age of the 25 patients included in the study was 34 (25-45) years and 72.0% were men. The septal perforation size of all patients was >2 cm and the etiological cause in all of them was previous septal surgery. All patients were followed for 12 months. The perforation was completely closed in 23 of 25 patients (92%). Conclusion: Using a different graft with an open rhinoplasty approach, we achieved a high success rate in patients with large septal perforations, followed for 1 month with nasal stenting and an average follow-up duration of 12 months.
