Abstract

Abstract:

Objective The long-term effect of muscular force balance reconstruction technique combined with intranasal fixation for correcting secondary nasolabial deformity after unilateral cleft lip was evaluated. The aim was to provide a basis for further improving the surgical treatment effect of secondary nasolabial deformity of acleft lip. Methods A total of 40 patients aged 4-28 years with secondary nasal deformity and unilateral cleft lip were selected as research subjects. The two-dimensional photo measurement analysis method was used in comparing the surgical results before and immediately after the operation (7 d) and 1 year after the operation. Results Columellar angle, nostril height ratio (NHR), alar rim angle, alar rim angle ratio, and nostril shape (NS) increased dimmediately after the operation, whereas alar base width ratio (ABWR) and nostril width ratio decreased (NHR) immediately after the operation (P<0.01). The ABWR, NHR, and NS immediately after the operation were not significantly different from those 1 year after the operation (P>0.05). Conclusion Muscular force balance reconstruction technique combined with intranasal fixation is effective in the repair of unilateral secondary nasolabial deformity, and stable results can be obtained 1 year after surgery.

Key words: unilateral cleft lip secondary nasolabial deformity, muscle reconstruction, secondary operation, muscular force balance
