Objective To discuss the operative method and therapeutic effect of correcting nasal deformity after prothesis of unilateral complete harel ip with design of nasal subunits. Methods From January 2006 to December 2008, 18 patients with nasal deformity after prothesis of unilateral complete harel ip were treated. There were 7 males and 11 femalesaged 6-26 years old. The deformity located on the left side in 11 cases and the right side in 7 cases with major manifestations of deviation and crispation towards normal side of nasal columella, applanation and collapse of nasal ala, lenity and dyssymmetry of nostrils, malposition of basement of nasal ala. Time between harel ip prothesis and secondary epithesis was 4-21 years (average 8 years). During epithesis, nasal columella were extended, collapse nasal alar cartilages were l iberated and fixed in symmetrical positions, injured upper l ip was extended with nasolabial flap or to “tongue-l ike” flap on nasal base. Eleven cases were implanted L-type sil icone prothesis to hump nose. Results For 1 case suffered postoperative rejection, the implant of L-type sil icone prothesis was taken out promptly, and reimplant of prothesis was performed 6 months later without postoperative rejection. The incision of the other patients all healed by first intention without any postoperative compl ications. The effect of epithesis was good with such manifestations as the eminence of injured nasal ala, normal radian, and symmetrical nostils. All patients werefollowed up for 3 months-2 years (average 8 months). The incision was hidden with well-maintained appearance and no obvious scar. Conclusion Based on feature of nasal subunits and formation causes of deformity, individual-orientated epithesis design of nasal ala margin, nasal columella basement incisions, reset and fix nasal alar cartilages and tissues values can provide the patients suffering the secondary nasal deformity with satisfied appearance.
