Abstract :

OBJECTIVE: The aim of the present study was to evaluate the cephalometric validity of Goslon yardstick in non-syndromic complete unilateral cleft lip and palate patients.

MATERIALS AND METHODS: The sample consists of lateral cephalograms and study models of 49 complete, non-syndromic, skeletal Unilateral Cleft Lip and Palate patients. The study models were assigned anonymous numbers and were then scored according to the Goslon yardstick by three investigators separately. A total of 19 hard tissue (17 skeletal and 2 dental) cephalometric measurements were assessed. Intra-class correlation coefficients (ICC) were calculated to determine intra-examiner correlation cephalometric measurements. The intra- and inter- examiner reliability of GOSLON yardstick was checked by using Cohen�s weighted kappa statistics. The correlation between Goslon yardstick and cephalometric parameters was analyzed by Spearman�s rank correlation test.

RESULTS: The mean age of the sample was 14.73 +- 3.99 years. A highly significant strong correlation was found to exist between the Goslon yardstick and cephalometric parameters for sagittal maxillo-mandibular relation. The vertical parameters; Gonial angle and FMA; showed a positive, moderate association.

Conclusion: The association between the Goslon score and the lateral cephalometric parameters proved the robustness of Goslon yardstick.
