Validity of the Cleft Aesthetic Rating Scale Does Not Improve with Inclusion of Fixed Scores for Atypical Outcomes.

OBJECTIVE: The Cleft Aesthetic Rating Scale (CARS) is a valid tool to assess the aesthetic outcome after unilateral cleft lip and palate (UCLP) repair. The goal of this study was to investigate whether the reliability of CARS increases by including fixed rates for atypical outcomes such as a smaller nostril, lower vermillion border or whistling deformity. DESIGN: 197 patients with UCLP who underwent cleft repair were included. Three cleft experts rated the post-operative photos using the original CARS, followed by a second assessment employing the modified CARS. SETTING: Medisch Centrum Leeuwarden, Universitair Medisch Centrum Groningen, Radboud Universitair Medisch Centrum and Amsterdam University Medical Center. PATIENTS: Photographs of 16- to 25-year-old patients with repaired UCLP. INTERVENTIONS: Two separate assessments using the original and modified CARS. MAIN OUTCOME MEASURES: The Intraclass Correlation Coefficient (ICC) was used to test inter-rater reliability of the original and modified version of the CARS. RESULTS: The reported ICC for the nose scored by means of the original and modified CARS were 0.68 (95% CI 0.62-0.74) and 0.66 (95% CI 0.59-0.72) respectively. The reported ICC for the lip assessed with the original and modified CARS were 0.53 (95% CI 0.33-0.67) and 0.57 (95% CI 0.34-0.72) respectively. CONCLUSIONS: No significant difference was found between the original and modified ICC of the nose and lip. The implementation of the fixed rates did not result in an increased reliability of the CARS. Therefore, we recommend the utilization of the original CARS.

The Cleft Aesthetic Rating Scale for 18-Year-Old Unilateral Cleft Lip and Palate Patients: A Tool for Nasolabial Aesthetics Assessment.

OBJECTIVE: To develop a reliable and easy-to-use method to assess the nasolabial appearance of 18-year-old patients with unilateral cleft lip and palate (CLP). DESIGN: Retrospective analysis of nasolabial aesthetics using a 5-point ordinal scale and newly developed photographic reference scale: the Cleft Aesthetic Rating Scale (CARS). Three cleft surgeons and 20 medical students scored the nasolabial appearance on standardized frontal photographs. SETTING: VU University Medical Center, Amsterdam. PATIENTS: Inclusion criteria: 18-year-old patients, unilateral cleft lip and palate, available photograph of the frontal view. EXCLUSION CRITERIA: history of facial trauma, congenital syndromes affecting facial appearance. Eighty photographs were available for scoring. MAIN OUTCOME MEASURES: The interobserver and intraobserver reliability of the CARS for 18-year-old patients when used by cleft surgeons and medical students. RESULTS: The interobserver reliability for the nose and lip together was 0.64 for the cleft surgeons and 0.61 for the medical students. There was an intraobserver reliability of 0.75 and 0.78 from the surgeons and students, respectively, on the nose and lip together. No significant difference was found between the cleft surgeons and medical students in the way they scored the nose ( P = 0.22) and lip ( P = 0.72). CONCLUSIONS: The Cleft Aesthetic Rating Scale for 18-year-old patients has a substantial overall estimated reliability when the average score is taken from three or more cleft surgeons or medical students assessing the nasolabial aesthetics of CLP patients.

The Asher-McDade Aesthetic Index in Comparison With Two Scoring Systems in Nonsyndromic Complete Unilateral Cleft Lip and Palate Patients.

OBJECTIVE: To compare the Asher-McDade aesthetic index with 2 systems used to score the appearance of the nasolabial area in patients with a complete cleft lip and palate. DESIGN: Retrospective analysis of the results of complete unilateral cleft lip and palate patients. SETTING: Academic Center for Dentistry of Amsterdam and the VU University Medical Center. PATIENTS: Six-year-olds with complete unilateral cleft lip and palate. MAIN OUTCOME MEASURES: Cleft lip and palate patients assessed using the scoring system proposed by Prahl et al, a 5-point ordinal scale, and the scoring system proposed by Asher-McDade et al by 6 judges, 3 orthodontists, and 3 plastic surgeons. A calculation of intra- and interobserver reliability was made. A comparison was made of all the assessment methods using Kendalls' tau. RESULTS: Photographs of 55 children (38 boys and 17 girls) with complete unilateral cleft lip and palate were assessed. For the scoring system of Prahl et al, interobserver reliability varied from 0.43 to 0.53, for the 5-point scale between 0.45 and 0.57, and for the scoring system by Asher-McDade et al these varied between 0.52 and 0.66. Multiple significant correlations were found between the used scoring systems. CONCLUSION: It can be concluded that the Asher-McDade aesthetic index is still superior to the other scoring systems used in this study. However, all 3 scoring systems can reliably be used when 3 or more observers are used.

Comparison of two scoring systems in the assessment of nasolabial appearance in cleft lip and palate patients.

OBJECTIVE: The aim of this study was to determine the reliability of 2 scoring systems. DESIGN: This study used a retrospective analysis of the results of complete unilateral cleft lip and palate patients. SETTING: The study was conducted at the VU Medical Center and the Academic Center for Dentistry of Amsterdam. PATIENTS: Patients were complete unilateral cleft lip and palate patients at the age of 6 years. MAIN OUTCOME MEASURES: Assessment of the nose and lip together and separately with a numerical photographic reference scoring system and with a 5-point ordinal scale without the use of a reference photograph by 6 judges. Intraobserver and interobserver reliability was calculated; both ways of assessment were compared by using Kendall tau. RESULTS: Photographs were available of 55 children (6 years old, 38 boys and 17 girls) with a complete unilateral cleft lip and palate. The interobserver reliabilities of the lip and nose together were 0.53 and, for the nose and lip separately, 0.51 and 0.43, respectively with the use of the numerical scale. In the 5-point scale, these were 0.55 for the nose and lip together and 0.57 and 0.45 for the nose and lip separately, respectively. Furthermore, it was found that the lip dominates in the scorings of the lip and nose together (linear regression analysis). CONCLUSIONS: The 2 tested systems are equivalent in their reliability and outcome. The lip is dominating in the overall scorings. It is advocated to use the 5-point scale without the use of a reference photograph and to assess the lip and nose separately.

Scoring systems of cleft-related facial deformities: a review of literature.

Objective : There is a need for an internationally agreed objective method of assessing cleft-related deformities in order to compare the results of individual surgeons and different surgical techniques or to determine the optimal timing for primary lip closure. To assess the current methods, an overview of the recent developments in postoperative scoring systems of cleft-related deformities was made. Methods : A Medline search from June 2003 through July 2011 was conducted, and references in the selected articles were checked. This search yielded 428 articles, and after application of the inclusion and exclusion criteria, 40 articles were included in this review. Results : Twenty-five studies used two-dimensional (2D) photographs for the assessment of cleft-related deformities. Fourteen of these studies used a subjective method for the assessment and 11 performed anthropometric measurements. Good reliability has been found for subjective assessments and measurements from 2D photographs. Fifteen studies assessed three-dimensional (3D) imaging. Conclusions : Although there is a wide variety in study design, 3D imaging seems most reliable in assessing cleft-related facial deformities. However, scoring on 2D photographs is easier to perform and more applicable in daily practice because all cleft patients are photographed through the course of their treatment.
