Correction of secondary unilateral cleft-lip nasal deformity using autologous costal cartilage grafts

Abstract

Objective To explore the comprehensive approach and efficacy of secondary unilateral cleft rhinoplasty by using autologous costal cartilage grafts. Methods Secondary rhinoplasty was performed in 28 patients with unilateral cleft-lip nasal deformity. The costal cartilage was harvested through a mini-invasive incision. Septal deviation was corrected, and nasal tip framework was reconstructed with the autologous costal cartilage through direct transcolumellar incision. Diced cartilage fragments were used to augment the depressed alar base. Nasolabial muscles were repositioned to restore the balance of muscular tension system. Results The appearance of the nasal deformity was greatly improved in all the 28 cases postoperatively by follow-up from 3 to 12 months. Increased stability and symmetry of the nasal tip, along with the improvement of nasal breathing function was achieved and sustained effectively. Conclusions Definitive secondary unilateral cleft rhinoplasty using autologous costal cartilage grafts provides good aesthetic and functional results.
