BackgroundIt is a common practice to subjectively categorize cleft lip deformities into narrow and wide cleft. The proposed grading of unilateral cleft lip can serve as a predictive factor of the difficulties to be encountered during repair and the expected outcome of surgery.Materials And MethodsThis was a 5-years retrospective study of the records of 32 patients with unilateral cleft lip that presented to a single surgical unit. We grouped the patients based on the age at surgery. We calculated the alar base width ratios of the cleft to non-cleft sides, and this was used for grading. We graded the clefts using ratio of 1.00-1.50 for mild cleft, 1.51 to 2.00 for moderate cleft, 2.01-3.00 for severe cleft, and >3.00 for extensive cleft lip.ResultsThe youngest child was 1 month old, while the oldest was 50 years. Majority of the patients (17) were older than 2 years at the time of surgery. Only nine babies (28.1% of the patients) were able to have their surgery done within the age of 6 months. Those that had extensive unilateral cleft lip were 10 (31.3%). However, a total of 18 (56.3% of the patients) had cleft lips that were either mild or moderate grade.ConclusionThis grading of unilateral cleft lip helps in objective preoperative assessment of the severity and in predicting the difficulty expected during lip repair. It is also helpful in assigning clefts to trainees and in determining which patients should be referred to an experienced surgeon.
