[Effectiveness of autologous costal cartilage transplantation in repair of Binder's syndrome].

OBJECTIVE

To investigate the technical points and effectiveness of autogenous costal cartilage transplantation in repair of Binder's syndrome.

METHODS

Between June 2012 and June 2017, 8 cases of Binder's syndrome were admitted. There were 3 males and 5 females, aged 16-31 years (mean, 22 years). All patients were conformed to the typical manifestations of Binder's syndrome. The autogenous costal cartilage was harvested and carved into the nasal dorsum graft, nasal column graft, and nasal basement graft. Before and after operation, standard pictures of the anterior view, lateral view, and base view were taken to measure facial related parameters of nasal dorsum length, nasal columella-lobule ratio, nasofrontal angle, nasal columella-upper lip angle, nasal tip projection rate, and nasion projection. Then the effectiveness of this surgical procedure for Binder's syndrome was evaluated.

RESULTS

All incisions healed by first intention without acute infections. All patients were followed up 6-36 months, with an average of 18 months. The foreign body sensation in upper lip and scar hyperplasia in thoracic incision occurred in 1 case, respectively. The nasal morphology improved significantly and the coordinated relationships of the nose with the upper lip and face were restored postoperatively. Postoperative parameter measurements were taken in 6 cases. The nasal dorsum length, nasal columella-lobule ratio, nasofrontal angle, nasal columella-upper lip angle, nasal tip projection rate, and nasion projection at preoperation were significantly improved when compared with the values at 6 months after operation ( P<0.05). The difference in nasal dorsum length, nasal tip projection rate, and nasion projection between actual values at 6 months after operation and normal values was no significant ( P<0.05). There was significant difference in nasal columella-lobule ratio between actual value at 6 months after operation and normal value ( P>0.05).

CONCLUSION

Autogenous costal cartilage transplantation in repair of Binder's syndrome can obviously improve patients' appearance of the external nose and middle face, and obtain the persistent effectiveness.
