Abstract: Introduction: The Great Ormond Street, London and Oslo, Norway [GOSLON] yardstick scale is an index for evaluating study models to determine the effects of treatment in individuals born with unilateral cleft lip and palate [UCLP]. GOSLON is a tool for ranking study models based on their sagittal, vertical, and transversal planes that requires calibration of the examiner. Aim: The aim of the study was to evaluate the interrelation between skeletal and dental malocclusion in unilateral cleft lip & / palate cases based on Goslon Yardstick Scale. Materials and methods: The study scored 80 study models [Mixed = 40, Permanent = 40] using Goslon yardstick scale and their lateral cephalograms were evaluated for interjaw relationship. Results: Significant interrater reliability was found for Golson yardstick scale. Goslon score 4was found in 40 %of study models of mixed dentition while Goslon score 2 and 3 each were found in 40 % of study models in permanent dentition. Significant correlation was found between Goslon score and skeletal cephalometric parameters.
