Objective assessment of the results of cleft lip and nose surgery is necessary to quantify differences between alternative surgical techniques. A previously described method of measuring facial asymmetry has been modified to allow a comparison of differently treated cleft noses (radical nasal correction versus no nasal correction).
Standardised, inferior view photographs of 10-year-olds were obtained from patient records. These were projected, traced, digitised and analysed using a BBC microcomputer. A method of excluding the ill-defined nasal baseline by obtaining a mirror-image of the upper nasal perimeter is described. The method has a high degree of inter and intra observer reproducibility.
