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

Abstract

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. 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. 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. CCDG graft can be a complementary option for avoiding postoperative irregular dorsum complications. This journal requires that authors assign a level of evidence to each article.
