Evaluation of Facial Profile Esthetics After Maxillomandibular Advancement Surgery for the Treatment of Obstructive Sleep Apnea.

PURPOSE: Maxillomandibuar advancement (MMA) surgery has been shown to be a successful treatment for obstructive sleep apnea (OSA), but concerns still exist regarding esthetic outcomes due to the large advancements involved. The objective of this study was to evaluate facial profile changes in patients who underwent MMA surgery for OSA by utilizing panels of external evaluators. METHODS: Pre- and posttreatment silhouettes of 21 patients (10 females, 11 males; mean age 43.2 [±11.5] years), who underwent MMA surgery for OSA, were generated from profile photographs. Utilizing survey software, the individual silhouettes were shown in random order to surgeons, orthodontists and laypeople, who assessed the esthetics of each via a sliding visual analogue scale (0 to 10). RESULTS: For all evaluators combined, postsurgical esthetic scores were significantly improved in 19 of 21 patients (P < .001). Ninety-five percent of evaluators judged the changes after surgery as positive or neutral. There was a mean increase in postsurgical esthetic scores of 1.9 [±1.9], which was moderately correlated with AHI changes (r = 0.48, P < .05). Mean esthetic score changes were significantly different between evaluator groups for 12 of 21 patients (P < .05), with surgeons and orthodontists reporting more positive change than laypeople. CONCLUSIONS: Overall, MMA surgery for the treatment of OSA does not have a negative impact on facial profile esthetics, with external evaluators judging the changes as favorable in the majority of patients assessed.

FACE-Q Craniofacial Module: Part 1 validation of CLEFT-Q scales for use in children and young adults with facial conditions.

BACKGROUND: The CLEFT-Q includes 12 independently functioning scales that measure appearance (face, nose, nostrils, teeth, lips, jaws), health-related quality of life (psychological, social, school, speech distress), and speech function, and an eating/drinking checklist. Previous qualitative research revealed that the CLEFT-Q has content validity in noncleft craniofacial conditions. This study aimed to examine the psychometric performance of the CLEFT-Q in an international sample of patients with a broad range of facial conditions. METHODS: Data were collected between October 2016 and December 2019 from 2132 patients aged 8 to 29 years with noncleft facial conditions. Rasch measurement theory (RMT) analysis was used to examine Differential Item Function (DIF) by comparing the original CLEFT-Q sample and the new FACE-Q craniofacial sample. Reliability and validity of the scales in a combined cleft and craniofacial sample (n=4743) were examined. RESULTS: DIF was found for 23 CLEFT-Q items when the datasets for the two samples were compared. When items with DIF were split by sample, correlations between the original and split person locations showed that DIF had negligible impact on scale scoring (correlations ≥0.995). In the combined sample, RMT analysis led to the retention of original content for ten CLEFT-Q scales, modification of the Teeth scale, and the addition of an Eating/Drinking scale. Data obtained fit with the Rasch model for 11 scales (exception School, p=0.04). Person Separation Index and Cronbach alpha values met the criteria. CONCLUSION: The scales described in this study can be used to measure outcomes in children and young adults with cleft and noncleft craniofacial conditions.

FACE-Q craniofacial module: Part 2 Psychometric properties of newly developed scales for children and young adults with facial conditions.

BACKGROUND: The FACE-Q Craniofacial Module is a patient-reported outcome measure designed for patients aged 8 to 29 years with conditions associated with a facial difference. In part 1, we describe the psychometric findings for the original CLEFT-Q scales tested in patients with cleft and noncleft facial conditions. The aim of this study was to examine psychometric performance of new FACE-Q Craniofacial Module scales. METHODS: Data were collected between December 2016 and December 2019 from patients aged 8 to 29 years with conditions associated with a visible or functional facial difference. Rasch measurement theory (RMT) analysis was used to examine psychometric properties of each scale. Scores were transformed from 0 (worst) to 100 (best) for tests of construct validity. RESULTS: 1495 participants were recruited with a broad range of conditions (e.g., birthmarks, facial paralysis, craniosynostosis, craniofacial microsomia, etc.) RMT analysis resulted in the refinement of 7 appearance scales (Birthmark, Cheeks, Chin, Eyes, Forehead, Head Shape, Smile), two function scales (Breathing, Facial), and an Appearance Distress scale. Person separation index and Cronbach alpha values met criteria. Three checklists were also formed (Eye Function, and Eye and Face Adverse Effects). Significantly lower scores on eight of nine scales were reported by participants whose appearance or functional difference was rated as a major rather than minor or no difference. Higher appearance distress correlated with lower appearance scale scores. CONCLUSION: The FACE-Q Craniofacial Module scales can be used to collect and compare patient reported outcomes data in children and young adults with a facial condition.
