    Abstract:
    PURPOSE: A surgical strategy for definitive cleft lip-nasal correction that stably provides symmetric and natural nasal forms has not been established to date. The purpose of this study was to describe our surgical techniques and 3-dimensional (3D) assessment results after the definitive correction of cleft lip-nose deformity using an extended spreader cartilage graft with a cross-lap joint technique to achieve a rigid strut for lower lateral cartilage repositioning to obtain a desirable nasal tip projection. PATIENTS AND METHODS: This study enrolled 14 patients with unilateral cleft lip (UCL) with or without cleft palate and 8 patients with bilateral cleft lip (BCL) with or without cleft palate who underwent definitive nose correction and were followed for 1 to 3 years. All patients were treated by open rhinoplasty, repositioning of the lower lateral cartilage, use of an extended spreader cartilage graft with a cross-lap joint technique for nasal tip support, and medial-upward advancement of nasolabial components with vestibular expansion by a free mucosal graft. For the BCL nose, pedicle flaps from rim skin were used for columella lengthening. Preoperative and postoperative nasal forms were 3-dimensionally analyzed by use of 3D images serially obtained in 12 patients. RESULTS: The postoperative nasal forms were satisfactorily improved in all patients, without any serious postoperative complications. Preoperative and postoperative 3D analyses showed a significantly projected nasal tip in the postoperative noses of patients in both the UCL group and the BCL group (P < .01 and P < .05, respectively) and a sharper nasal tip angle in the BCL group (P < .05). Lateral deviation of the nasal tip was significantly improved in the center of the face in patients in the UCL group (P < .01). CONCLUSIONS: The results of this study suggest that the extended spreader cartilage graft using the cross-lap joint graft technique is useful to provide a desirable projection of the nasal tip in the center of the face on definitive correction of both UCL and BCL nose deformities.
