ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effective method for correction of nasal deformity after unilateral cleft lip.</p><p><b>METHODS</b>50 cases with secondary nasal deformity after unilateral cleft lip were retrospectively analyzed. All the patients underwent nasal and lip muscle reposition operation to restore the symmetry of nasal alar.</p><p><b>RESULTS</b>The nasal deformity was greatly improved in all the 50 cases. The malposition of nasal column and nasal alar was corrected. The symmetry was markedly improved. The measurement before and after operation showed significant difference ( P<0.05).</p><p><b>CONCLUSIONS</b>The reasons of secondary nasal deformity after unilateral cleft lip are complicated. The muscle reposition operation can effectively improve the deformity.</p>
