Abstract

Abstract: Objective

This study aimed to compare the postoperative outcome of the new and classical muscular reconstruction technique combined with nasal internal-fixation method for secondary deformity post unilateral cleft lip repair. A rationale is provided for the further surgical improvement of secondary deformities.

Methods

Sixty patients aged 4-18 years with secondary unilateral cleft lip-nose deformity were involved in this research. The deformities of 28 patients were repaired using the muscular force balance technique through nasal internal fixation method, and 32 were repaired using classical muscular reconstruction technique. Two-dimensional analysis was used to evaluate the nose-lip morphology of pre- and post-operative patients through standardized photographs seven days after surgery.

Results

Compared with preoperative nasal morphology in the muscular force balance technique group, the 7-days postoperative results of this group showed the significantly improved short-term outcomes in the correction of columellar deflection, alar rim angle, nasal shape, and the symmetry of alar base width, nostril width, nostril height, alar rim angle (P<0.05).

Conclusion

The new muscular reconstruction technique with nasal internal-fixation method has a significant effect on nasal repair.

Key words: secondary deformity post unilateral cleft lip repair, nasal deformity, secondary repair, force-ba-lanced muscular reconstruction
