Abstract

Objective:

The purpose of this study is to ascertain objective nasal measurements from the basal view that are predictive of nasal esthetics in individuals with secondary cleft nasal deformity.

Design:

Thirty-three patients who had undergone unilateral cleft lip repair were retrospectively reviewed in this study. The degree of nasal deformity was subjectively ranked by seven surgeons using standardized basal-view measurements. Nine physical objective parameters including angles and ratios were measured. Correlations and regressions between these objective and subjective measurements were then analyzed.

Results:

There was high concordance in subjective measurements by different surgeons (Kendall's harmonious coefficient = W = .825,P= .006). The strongest predictive factors for nasal aesthetics were the ratio of length of nasal alar (r= .370,P= .034) and the degree of deviation of the columnar axis (r= .451,P= .008). The columellar angle had a more powerful effect in rating nasal esthetics.

Conclusion:

There was reliable concordance in subjective ranking of nasal esthetics by surgeons. Measurement of the columnar angle may serve as an independent, objective predictor of esthetics of the nose.
