Crushed Septal Cartilage-Covered Diced Cartilage Glue (CCDG) Graft: A Hybrid Technique of Crushed Septal Cartilage.

Background: Diced cartilage glue (DG) grafts have been widely used in dorsal augmentation but can induce dorsal irregularities. The authors evaluated the postoperative feasibility of a crushed septal cartilage-covered diced cartilage glue (CCDG) graft.

Methods: The medical records of 38 patients who underwent dorsal augmentation rhinoplasty with an open approach were retrospectively reviewed. DG graft was used in 18 patients (47.4%), and CCDG graft was used in 20 patients (52.6%). Surgical outcomes were assessed by comparing anthropometric data on facial photographs and satisfaction questionnaires on aesthetic outcomes and palpable irregularities on nasal dorsum before and after surgery.

Results: Both groups showed successful aesthetic outcomes. Dorsal height, radix height, and tip projection were all increased postoperatively in both groups. Tip rotation did not significantly increase (p > 0.05). Both groups showed similar outcomes in terms of aesthetic satisfaction but a significant difference in palpable irregularity. CCDG graft group showed significantly better (p = 0.04) satisfaction with dorsal irregularities (4.15 ± 0.75) than the DG graft group (3.56 ± 0.92). CCDG graft group also showed significantly better mean values (p = 0.048) in the degree of irregularity by two surgeons (3.85 ± 0.65) than the DG graft group (3.25 ± 0.97). No patient had significant complaints about irregular dorsum, and none of them underwent a revision rhinoplasty.

Conclusion: CCDG graft can be a complementary option for avoiding postoperative irregular dorsum complications.
