Dorsal Augmentation Using Crushed Autologous Costal Cartilage in Rhinoplasty.

[OBJECTIVE/HYPOTHESIS] For dorsal augmentation in rhinoplasty, autologous costal cartilage can be used in many different forms, including its crushed form. While only few studies have reported the outcome of dorsal augmentation using the crushed autologous costal cartilage, the current study aims to evaluate the outcome of such usage.

[STUDY DESIGN] Retrospective chart review.

[METHODS] The records of 38 patients were reviewed retrospectively. The study period was from 2006 to 2016. All enrolled patients underwent rhinoplasty that includes dorsal augmentation using crushed autologous costal cartilage. Three facial plastic surgeons evaluated the outcome using pre- and postoperative facial photographs. Patients' satisfaction was also analyzed. Anthropometric measurement was performed, and postoperative complications were investigated.

[RESULTS] Our cohort included 19 primary and 19 revision cases. The mean age of the patients was 31.0 years. Mean postoperative follow-up period was 36.1 months. According to facial plastic surgeons' evaluation, excellent, good, fair, poor aesthetic outcomes were achieved in 15 (39.5%), 18 (47.4%), 5 (13.1%), 0 (0.0%) cases, respectively. Patients were very satisfied, satisfied, moderate, dissatisfied in 16 (42.1%), 15 (39.5%), 6 (15.8%), 1 (2.6%) cases, respectively. Heights of the dorsum and radix were significantly increased after surgery (for each, p < 0.05). There were 11 cases (28.9%) of complications on the dorsum, four surface irregularity, five resorptions, and two cases of short nose deformity.

[CONCLUSIONS] One can augment the nasal dorsum significantly with crushed autologous costal cartilage. But considering high rate of recipient site complications, this method may better be used as an alternative technique when surgical situations are indicated.
