Application of polyterafluoroethylene in repairing secondary nasal deformity of unilateral cleft lip after opration

Objective To explore the methodology of repairing secondary nasal deformity of congenital unilateral cleft lip after operation and clinical outcome of the patients. Methods The repairing operation were performed in 46 cases,in which polyterafluoroethylene (PTFE) implants were inserted into a pocket under the nasal dorsum, ala or base through a small incision. Results The flat nasal dorsa, tips and hollow nosal base were elevated. The profile view of noses was improved apparently. The outcome was satisfactory. Conclusion PTFE is a optimal plastic material,which is compatible perfectly with circumferential tissues. The outcome of filling is excellent. Therefore, this technique is one of the efficient methods to repair secondarynasal deformity of unilateral cleft lip.
