Abstract:

BACKGROUND: The soft tissues would shrink with nasal framework collapse following surgical trauma, which cause aseptic inflammation, lead to parts of cartilage resorption. Accordingly, long-term saddle nose deformity usually accompanied by short nasal columella. Complications such as skin perforation or ulceration would appear if corrected the deformity using medical silicone rubber with large tension.
OBJECTIVE: To explore the effectiveness of repairing post-traumatic saddle nose deformity with autologous costal cartilage transplantation.
METHODS: A total of 21 cases with post-traumatic saddle nose deformity accompanied by short nasal columella were selected, including 6 males and 15 females, aged 16-45 years. All of the cases had trauma history and agreed with the treatment. The costal cartilage was obtained from the seventh rib and formed to babylon weeping willow leaf shape and columella nasi stent to repair post-traumatic saddle nose deformity. The “V-Y” progradation suture was used in the philtrum introcession and the bottom of nasal columella to extend the nasal columella. The recovery of saddle nose deformity after transplantation, discharge of transplanted cartilage, as well as the incision scar status was observed.
RESULTS AND CONCLUSION: The results were satisfactory and there were no complications after transplantation. All the cases were followed up from 6 months to 2 years. No case suffered costal cartilage grafts discharge or chondral deformation. The scar was little at the bottom of nasal columella. It is an ideal method for repairing post-traumatic saddle nose deformity using transplantation of autologous costal cartilage with “V-Y” progradation suture.
