ABSTRACT
Objective@#To discuss the use of butterfly costal cartilage as columella strut graft.@*Methods@#On the costal cartilage that being cut, butterfly graft was designed length of 2.8 cm, upper and lower end thickness of 5 mm, middle part thickness of 1.5 mm. The lower end was designed with a groove about 1 cm in length, the width of the lower end of the butterfly graft was determined according to the degree of retraction at the caudal end of the septum, then insert to the nasal crest. The posterior end of two lamella grafts was sutured and fixed with the middle part of the nasal columnar strut graft.@*Results@#From November 2016 to March 2018, about 150 patients underwent rhinoplasty with this method, follow-up was 3 to 12 months. Two cases had mild nasal tip deviation one month after surgery and were adjusted with auricular cartilage three months later. Three patients had mild postoperative hyporotation and adjustment three months postoperatively, residual had good shape.@*Conclusions@#The stability and controllability of the sphenoid columella strut graft are good, out of shape not easily, It is a worthy clinical method.
