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: Nasal septal perforation (NSP) is characterized by defects in the mucosal, cartilaginous, and bony structures of the septum, most commonly resulting from septoplasty. Spontaneous healing of NSPs is rare, necessitating surgical intervention once the condition stabilizes. Numerous techniques have been developed for NSP repair. This study presents a novel technique combining fascia lata grafts, platelet-rich plasma (PRP), and diced septal cartilage harvested from the patient’s remaining deviated nasal septum for the repair of medium-sized NSPs. Methods: A retrospective analysis was conducted on 32 patients who underwent NSP repair between July 2022 and July 2023. The repair utilized fascia lata, PRP derived from venous blood, and diced cartilage from residual septal cartilage. The procedure involved an open rhinoplasty approach for graft placement, followed by stabilization using endoscopic techniques. Results: The mean horizontal and vertical diameters of the septal perforations were 12.06 ± 2.87 mm and 13.12 ± 2.44 mm, respectively. All patients had medium-sized perforations (0.5-2 cm). The mean follow-up period was 12.03 ± 1.11 months. Complete closure was achieved in 28 of 32 cases (87.5%). The cohort included 18 males (56.3%) and 14 females (43.8%), with a mean age of 35.47 ± 5.31 years (range: 25-45). Ten patients (31.3%) were smokers, among whom 4 experienced incomplete closure. Smoking was not significantly associated with repair failure (P = .06). Conclusion: This novel technique combining fascia lata, PRP, and diced septal cartilage offers a reliable and effective approach for the repair of medium-sized NSPs. © The Author(s) 2025.
