Objective: There is debate on the reliability of the Americleft Yardstick (AY) global nasolabial appearance assessment method. The objective was to analyze the effect of the additional basal view (BV) feature on the reliability of the AY method for Japanese children with complete cleft lip and palate (CUCLP).
Design: Blind retrospective analysis of clinical records on 43 patients (5- to 7-year-old) with nonsyndromic CUCLP who underwent primary lip repair from 2005 to 2011.
Main Outcome Measure: Color pictures published in AY and Rubin's studies were used as reference pictures. Patients' photographs were cropped and rated on a 5-point scale for the vermilion border (VB), nasolabial frontal (NLF), and nasolabial profile (NLP) according to AY with/without BV assessment by Rubin's methods. Rating was performed twice by 3 oral surgeons. Intra- and inter-rater reliabilities were analyzed using weighted κ, and correlations between BV and other features were analyzed.
Results: Overall average assessment scores were 2.742 (0.573) with AY and 2.702 (0.489) with AY+BV methods ( = .728). Average intra-rater reliabilities were 0.605 and 0.611 and average inter-rater reliabilities were 0.525 and 0.48 with AY and AY+BV, respectively. Inter-rater reliability was the lowest for NLP. ρ scores between BV versus VB, NLF, and NLP were 0.025, 0.659, and 0.092, respectively.
Conclusions: Present study demonstrates moderate intra- and inter-rater reliabilities obtained with the AY assessment method for Japanese children with CUCLP. Nasolabial profile standard ambiguity may lead to the poor reliability of AY assessment. Addition of the BV feature does not improve overall reliability.
