Which index should be used to measure primary surgical outcome for unilateral cleft lip and palate patients?


ABSTRACT:

Objective

To determine the optimal dentoalveolar measure to assess unilateral cleft lip and palate (UCLP) patient plaster models.

Design

The models of 34 patients with UCLP taken at 5, 10, and 15-20 years of age were scored by two examiners on two separate occasions using five indices: the 5 Year Olds' (5YO), GOSLON, Modified Huddart/Bodenham (MHB), EUROCRAN, and Overjet. Reliability, validity, and ease of use were recorded for each index/examiner.

Setting

All models were scored in either Bristol Dental Hospital or Derriford Hospital, Plymouth, United Kingdom by senior orthodontic clinicians.

Results

Highest overall reliability was seen with MHB (Kappa = 0.56-0.97). Predictive validity was similar for MHB, GOSLON, and 5YO with a 50-65 per cent prediction of final outcome from 5 and 10 years. EUROCRAN palatal index showed no clear predictive validity (Spearman's correlation = 0.20-0.21). Agreement to the gold standard 5YO score at the 5-year age group was high for MHB (Kappa = 0.83) and moderate for GOSLON (Kappa = 0.59). Agreement to the gold standard GOSLON score at 10 years was highest for 5YO (Kappa = 0.69), followed by Overjet (Kappa = 0.59) and MHB (Kappa = 0.46). Time to score 34 models per index (minutes): GOSLON (13.4) < Overjet (13.6) < 5YO (19.4) < EUROCRAN (24.8) < MHB (27.4).

Conclusion

As an outcome measure of UCLP models, only MHB and 5YO indices can be recommended for use at 5 years of age and GOSLON at 10 years of age.
