RESUMO
Objective To explore the application and efficacy of autogenous septal cartilage in the correction of cleft lip nasal deformity.Methods A total of 31 patients with secondary nasal deformity of cleft lip were involved in this study.After autologous nasal cartilage was released,the dislocation of nasal cartilage was corrected,nasal septum cartilage was used as substitute to raise the alar collapse,to reshape the nasal tip cartilage structure and correct the nasal deformity.Results Postoperative incision was primarily healing.For cartilage donor area there was no serious complications,and incision scar was concealed and unobvious; after 6 months to 2 years follow-up,there was no cartilage absorption deformation,the tip of the nose was flat,crack side nosewing collapses,and nasal columella skew was totally corrected,with stable rhinoplasty effects.Conclusions For secondary nasal deformity of cleft lip,the use of nasal septum cartilage to repair nose deformity can not only solve the cartilage source,but also give septal straightening and at the same time the correction effect of external nasal deformity is good.
