Abstract:
Millard presented the concept of rotation advancement for unilateral cleft lip repair, and today this method of cleft lip closure is acknowledged by most as optimal in principle. However, it has been noted that this procedure occasionally can produce a scar that is symmetrical on the lower two-thirds of philtral column. The scar crosses the upper one third of the philtrum obliquely. The purpose of our study is to determine the configuration of the philtrum. 200 newborn infants were examined from June 1998 to September 1998. Mean gestational ages were 39 weeks and 5 days. Mean birth weight was 3226 gm. Multiple parameters such as philtral shape, nostril sill shape, vermilion shape, curvature of Cupid's bow, mean philtral length, mean white roll length, mean Cupid's bow length, and mean distance between both commissures were applied. An arbitrary classification of the philtrum was established to divide these infants into five groups. As a result, the parallel philtral column from nostril base to vermilion border(Type lla) was found to be the most popular type. Most common vermilion shape was protrusion type. Normal curve of Cupid's was most common. Mean values of philtral length, white roll length, Cupid's length, and distance between commissures were 8.3+/-1.1 mm, 13.9+/-1.3 mm, 5.7+/-1.0 mm, 24.7+/-2.3 mm, respectively. We believe this classification system will be useful for newborn infants evaluation and analysis, systemic planning and application of proper cleft lip repair procedure.
