Radical overlapping intravelar veloplasty during primary cleft palate repair results in decreased secondary speech surgery.

BACKGROUND: There is growing evidence that performing a radical intravelar veloplasty (IVV) improves speech outcomes. The aim of this study was to determine the impact of a radical IVV during primary palatoplasty on the rate of secondary speech surgery. METHODS: This is a retrospective review of primary palatoplasty using an IVV performed by a single surgeon from the year 2000 to 2023. In 2008, the surgeon changed technique to involve a more radical IVV. The radical overlapping IVV involves release of the palatopharyngeus from the posterior hard palate and from the nasal component of the tensor veli palatini, release of the levator veli palatini to the levator tunnel, and overlapping of the palatopharyngeus-levator unit across the midline after retro-positioning. This separated the patients into a before and after technique change group. The rate of secondary speech surgery was compared between the two time periods. RESULTS: An IVV was performed during straight line repairs 333 and 272 times during the first and second time periods, respectively. The second radical overlapping IVV group had significantly (p<0.05) less secondary speech surgery procedures at 43 (15.81%) compared to 83 (24.92%) amongst the first conservative IVV group (p<0.05). CONCLUSIONS: Precise anatomical dissection, extensive release, retro-positioning and overlap of the velar musculature during IVV results in significantly less secondary speech surgery.

Survival and infection rates of microvascular free flaps in pediatric mandibular reconstruction: A systematic review and meta-analysis.

BACKGROUND: Vascularized free tissue transfer has been established as an effective method in the reconstruction of mandibular defects. However, a limited understanding of its efficacy in pediatric patients persists due to its infrequent presentation. The aim of this study is to systematically consolidate the survival and infection rates of free flaps in pediatric mandibular reconstruction. METHODS: A systematic literature search was conducted on Ovid Medline, Embase, and Cochrane Library for studies published up to January 2024. We included peer-reviewed studies reporting on survival and infection outcomes associated with free flap mandibular reconstruction in pediatric patients (<18 years). We performed a random-effects meta-analysis with the inverse-variance weighted approach to estimate survival and infection rates. Heterogeneity was assessed by I2, and publication bias was examined using Egger's test. RESULTS: A total of 26 studies, reporting on 463 free flaps and 439 pediatric patients with a mean age of 10.7 years, were included in our study. Most free flaps originated from the fibula (n = 392/463, 84.7%) and benign tumors were the most common cause for mandibular reconstruction (n = 179/463, 38.7%). The pooled estimate for survival of flaps was 96% (95% CI: 93-97, I2 = 0%), and recipient-site infections were estimated to occur in 9% (95% CI: 6-13, I2 = 0%) of cases. The most common reported complications within the study timeframe were early malocclusion (n = 28/123, 21.4%) and bite abnormalities (18/131, 13.7%). CONCLUSION: Free tissue transfer for mandibular reconstruction in pediatric patients is effective and safe. Further research is required to explore functionality following mandibular reconstruction in diverse pediatric populations.

Evaluation of a high-fidelity cleft alveolar bone graft simulator.

INTRODUCTION: Cleft alveolar bone graft surgery is technically challenging to perform as well as difficult to learn and teach. A high-fidelity cleft alveolar bone graft simulator was previously developed. However, further evaluation of the simulator is necessary to assess its efficacy. METHODS: Two cleft simulation workshops were conducted in which participants were led through a simulated cleft alveolar bone graft. The first simulation workshop involved six plastic surgery trainees. The second workshop involved 43 practicing cleft surgeons. The participants were provided with a Likert-type questionnaire assessing the simulators' features, realism, and value as a training tool. The change in self-reported confidence was assessed by providing each participant with a pre- and post-simulation confidence questionnaire. RESULTS: There was overall agreement in the realism of the simulators' features (average score of 4.67 and 3.80 out of 5 for the trainees and surgeons, respectively). There was overall agreement to strong agreement in the simulators value as a training tool (average score of 5 and 4.43 out of 5 for the trainees and surgeons, respectively). The self-reported confidence increased for all questionnaire items for both the trainees and surgeons. This was significant (p < 0.05) for five out of eight and all questionnaire items for the trainees and surgeons, respectively. The magnitude of the confidence increase was generally greater for less experienced participants. CONCLUSION: The cleft alveolar bone graft simulator was found to be realistic and valuable as a training platform. Use of the simulator improved self-reported confidence in cleft alveolar bone graft surgery.

Patient factors associated with novel EAR-Q appearance, psychosocial, and social scales: A cross-sectional study and regression analysis.

INTRODUCTION: The EAR-Q is a rigorously validated patient-reported outcome measure, which evaluates ear appearance and health-related quality of life (HRQL) in patients with congenital or acquired ear conditions. The aim of this study was to conduct an exploratory analysis to examine the factors associated with EAR-Q appearance and HRQL scale scores. METHODS: In this study, 862 participants, aged 8-29 years, with congenital or acquired ear conditions, completed the EAR-Q as part of an international field-test study. Patients responded to demographic and clinical questions as well as the EAR-Q. Univariable and multivariable linear regression analyses were used to determine factors that were significant predictors for the scores on the EAR-Q Appearance, Psychological, and Social scales. RESULTS: Most participants were men (57.4%), awaiting treatment (55.0%), and had a microtia diagnosis (70.4%), with a mean age of 13 (±4) years. Worse ear appearance scores (p < 0.02) were associated with male gender, microtia, no history of treatment, ear surgery within 6 months, unilateral involvement, and greater self-reported ear asymmetry. Decreased psychological scores (p < 0.01) were associated with increasing participant age, no treatment history, recent ear surgery, and dissatisfaction with ears matching or overall dissatisfaction. Lower social scores (p ≤ 0.04) were associated with no treatment history, those awaiting surgery, ear surgery within the last 6 months, bilateral involvement, and self-reported ears matching or overall appearance. CONCLUSION: This analysis identified patient factors that may influence ear appearance and HRQL scale scores. These findings provide evidence of patient factors that should be adjusted for when undertaking future observational research designs using the EAR-Q in this patient population.

Bilateral Cleft lip Simulation.

OBJECTIVE: To evaluate the features, anatomic accuracy, and educational value of a high-fidelity bilateral cleft lip simulator. DESIGN: Evaluation of the simulator by expert cleft surgeons after performing a simulated bilateral cleft lip repair. SETTING: The simulator was evaluated by the surgeons during the Latin American Craniofacial Association meeting. PARTICIPANTS: Eleven experienced cleft surgeons evaluated the simulator. The cleft surgeons were selected based on their availability during the meeting. INTERVENTIONS: The participants performed a simulated bilateral cleft lip repair. They were each provided with a questionnaire assessing the simulator's features, realism and value as a training tool. MAIN OUTCOME MEASURE (S): The main outcome measure are the scores obtained from a Likert-type questionnaire assessing the simulators features, realism and value. RESULTS: Overall, the surgeons agreed with the simulator's realism and anatomic accuracy (average score of 3.7 out of 5). Overall, the surgeons strongly agreed with the value of the simulator as a training tool (average score of 4.6 out of 5). CONCLUSIONS: A high-fidelity bilateral cleft lip simulator was developed that is realistic and valuable as a training tool. The simulator provides a comprehensive training platform to gain hands-on experience in bilateral cleft lip repair before operating on real patients.

Cleft lip and/or palate mortality trends in the USA: a retrospective population-based study.

BACKGROUND: Cleft lip and/or palate (CL/P) is one of the most common congenital anomalies worldwide. Although CL/P management may require a series of interventions, mortality resulting from CL/P alone is rare. This study aims to examine recent trends of CL/P mortality rates in the USA. METHODS: A retrospective population-based study was conducted using official US birth and death certificate data from the Centers for Disease Control and Prevention from 2000 to 2019. Annual mortality rates per 1000 births with CL/P were calculated across sex and racial groups. Multivariable logistic regression models estimated the effects of sex and race on the risk of mortality with CL/P, and linear regression models were used to examine temporal changes in mortality rate across sex and race. RESULTS: From 2000 to 2019, 1119 deaths occurred in patients with documented CL/P, for an overall incidence of 20.3 deaths per 1000 births with CL/P (95% CI 18.9 to 22.8). Of these, Patau syndrome was the listed cause of death in 167 cases (14.9%). Black individuals (OR 1.93, 95% CI 1.85 to 2.01), Hispanic (1.54, 1.49 to 1.58) and American Indian individuals (1.28, 1.20 to 1.35) were at a greater risk of CL/P mortality compared with white individuals. Additionally, females were also at a greater risk (1.35, 1.21 to 1.49). A significant upward trend in CL/P mortality was observed in Hispanic (r2=0.70, p<0.01) and American Indian individuals (r2=0.81, p<0.01) from 2000 to 2019. CONCLUSIONS: Cleft birth and mortality surveillance is essential in healthcare and prevention planning. Future studies are required to understand the differences in CL/P mortality rates across various sociodemographic groups.

Establishing Reliability and Validity of the FACE-Q Craniofacial Module for Pediatric Head and Neck Cancer.

Purpose: We aimed to establish content validity and assess the psychometric properties of the FACE-Q Craniofacial Module, a patient-reported outcome measure, for use in pediatric and adolescent patients with head and neck cancer (HNC). Methods: To establish content validity (Part 1), between June 2017 and August 2019, cognitive interviews were conducted with survivors of pediatric HNC (n = 15), and input was obtained from clinical experts (n = 21). To examine item and scale performance (Part 2), Rasch Measurement Theory (RMT) analysis was performed using data from two international studies (n = 121). Results: Part 1: Qualitative data from 15 survivors and input from 21 experts provided evidence to support the use of the FACE-Q Craniofacial Module in pediatric HNC. Part 2: The field-test study sample included 121 survivors of pediatric HNC. RMT analysis provided evidence of reliability and validity for 10 FACE-Q scales. Data for each scale fit the RMT model. Scale reliability was high, with Person Separation Index and Cronbach's alpha values ≥0.82 for 9 scales. Mean scores on the Appearance, Psychological, and Social scales were higher for those who liked aspects of their face more. For participants with (vs. without) a facial difference, mean scores were lower for the Face, Jaws, Psychological, and Social scales. Conclusion: The FACE-Q Craniofacial Module evidenced reliability and validity for HNC survivors aged 8-29 years and can be used in research and clinical care to measure quality of life of pediatric survivors with HNC.

Development and Evaluation of a High-Fidelity Rhinoplasty Simulator.

SUMMARY: Rhinoplasty is a challenging procedure with a steep learning curve. Surgical simulators provide a safe platform to gain hands-on experience without compromising patient outcomes. Therefore, rhinoplasty is an ideal procedure to benefit from an effective surgical simulator. A high-fidelity rhinoplasty simulator was developed using three-dimensional computer modeling, three-dimensional printing, and polymer techniques. The simulator was tested by six surgeons with experience in rhinoplasty to assess realism, anatomic accuracy, and value as a training tool. The surgeons performed common rhinoplasty techniques and were provided a Likert-type questionnaire assessing the anatomic features of the simulator. A variety of surgical techniques were performed successfully using the simulator, including open and closed approaches. Bony techniques performed included endonasal osteotomies and rasping. Submucous resection with harvest of septal cartilage, cephalic trim, and tip suturing, as well as grafting techniques including alar rim, columellar strut, spreader, and shield grafts, were performed successfully. Overall, there was agreement on the simulator's anatomic accuracy of bony and soft-tissue features. There was strong agreement on the simulator's overall realism and value as a training tool. The simulator provides a high-fidelity, comprehensive training platform to learn rhinoplasty techniques to augment real operating experience without compromising patient outcomes.

Outcomes of Digit Replantation in Children: A Systematic Review.

Background: Children have been suggested to benefit from digit replantation due to a greater neurogenerative capacity. We aimed to conduct a systematic review on digit replantation in children to provide a comprehensive overview of survival rates and functional outcomes. Methods: A systematic literature search was conducted on Ovid MEDLINE, Embase, and the Cochrane Controlled Register of Trials for studies published between 1980 and 2023. We included peer-reviewed studies reporting on digit survival rates in pediatric patients under the age of 18 years who underwent single or multiple digit replantations distal to the metacarpophalangeal joint. Preoperative, intraoperative, and postoperative outcomes were extracted, and pooled estimates were derived using univariable analysis. Results: Twenty-two studies reporting on 761 patients and 814 digit replantations were included in our study. Most replantations occurred in the index (n = 74), Tamai zone I (n = 168), and from clean-cut injuries (n = 190). The mean survival rate was 76% (n = 618/814), with a mean range of motion at the distal interphalangeal joint ranging from 64 degrees to 90 degrees and two-point discrimination ranging from 3.8 mm to 6.4 mm. Compared with clean-cut injuries, digit replantations from avulsion [odds ratio (OR), 0.81; 95% confidence interval (CI), 0.74-0.89] or crush (OR, 0.71; 95% CI, 0.59-0.82) injuries were associated with a lower odds of survival. Digit replantations performed with two venous (OR, 1.43, 95% CI; 1.28-1.59) or arterial anastomoses (OR, 1.65; 95% CI, 1.48-1.81) were associated with a higher odds of survival. Conclusions: Our systematic review suggests that digit replantation may be a viable option in children. Further research is required to explore functionality after digit replantation in diverse pediatric populations.

The First Alveolar Bone Graft Simulator.

Alveolar bone graft (ABG) surgery in cleft patients is technically challenging. The procedure requires design, dissection and release of soft tissue flaps to create a seal around the bone graft. In addition, visualization during the procedure is challenging within the confines of the cleft. These features make ABG surgery difficult to learn and teach, and it is, therefore, a suitable procedure for the use of a simulator. A high-fidelity cleft ABG simulator was developed using three-dimensional printing, polymer, and adhesive techniques. Simulated ABG surgery was performed by two expert cleft surgeons for a total of five simulation sessions to test the simulator's features and the ability to perform the critical steps of an ABG. ABG surgery was successfully performed on the simulator. The simulations involved interacting with realistic dissection planes as well as multi-layered synthetic soft (periosteum, mucosa, gingiva, adipose tissue) and hard (teeth, bone) tissue. The simulator allowed performance of cleft marginal incisions, dissection, and elevation of a muco-gingival-periosteal flap, creation of nasal upturned and palatal downturned flaps, nasal and palatal side closure, insertion of simulated bone graft material, and advancement of the muco-gingival-periosteal flap for closure of the anterior wall of the cleft. The ABG simulator allowed performance of the critical steps of ABG surgery. This is the first ABG simulator developed, which incorporates the features necessary to practice the procedure from start to finish.

Determining Construct Validity of a Patient-Reported Outcome Measure for Birthmarks on the Face and Body.

Background: The FACE-Q Craniofacial module includes a scale that measures how bothered an individual is by the appearance of a birthmark on the face or body. Objective: To determine if the Birthmark scale measuring appearance of the birthmark has evidence of construct validity among children and young adults, aged 8-29 years old, with a birthmark on the face or body. Methods: Participants were recruited as part of the field test of the FACE-Q Craniofacial module. Construct validity of the Birthmark scale was examined using a priori hypotheses testing. Results: Two hundred seventy participants were included, who were predominantly female (60.4%) and had a facial birthmark (71.5%). The Birthmark scale correlated (p ≤ 0.01) with scale scores for Face, Appearance Distress, Psychological, School, and Social. Scores for participants with more "noticeable" birthmarks were (p ≤ 0.01) associated with worse Birthmark scale scores. Conclusion: The findings support that the Birthmark scale can be used to measure the patient's perspective of the appearance of their birthmark, providing a means for clinicians to incorporate the patient's view in shared decision-making and research.

The Development, Deployment, and Evaluation of the CLEFT-Q Computerized Adaptive Test: A Multimethods Approach Contributing to Personalized, Person-Centered Health Assessments in Plastic Surgery.

BACKGROUND: Routine use of patient-reported outcome measures (PROMs) and computerized adaptive tests (CATs) may improve care in a range of surgical conditions. However, most available CATs are neither condition-specific nor coproduced with patients and lack clinically relevant score interpretation. Recently, a PROM called the CLEFT-Q has been developed for use in the treatment of cleft lip or palate (CL/P), but the assessment burden may be limiting its uptake into clinical practice. OBJECTIVE: We aimed to develop a CAT for the CLEFT-Q, which could facilitate the uptake of the CLEFT-Q PROM internationally. We aimed to conduct this work with a novel patient-centered approach and make source code available as an open-source framework for CAT development in other surgical conditions. METHODS: CATs were developed with the Rasch measurement theory, using full-length CLEFT-Q responses collected during the CLEFT-Q field test (this included 2434 patients across 12 countries). These algorithms were validated in Monte Carlo simulations involving full-length CLEFT-Q responses collected from 536 patients. In these simulations, the CAT algorithms approximated full-length CLEFT-Q scores iteratively, using progressively fewer items from the full-length PROM. Agreement between full-length CLEFT-Q score and CAT score at different assessment lengths was measured using the Pearson correlation coefficient, root-mean-square error (RMSE), and 95% limits of agreement. CAT settings, including the number of items to be included in the final assessments, were determined in a multistakeholder workshop that included patients and health care professionals. A user interface was developed for the platform, and it was prospectively piloted in the United Kingdom and the Netherlands. Interviews were conducted with 6 patients and 4 clinicians to explore end-user experience. RESULTS: The length of all 8 CLEFT-Q scales in the International Consortium for Health Outcomes Measurement (ICHOM) Standard Set combined was reduced from 76 to 59 items, and at this length, CAT assessments reproduced full-length CLEFT-Q scores accurately (with correlations between full-length CLEFT-Q score and CAT score exceeding 0.97, and the RMSE ranging from 2 to 5 out of 100). Workshop stakeholders considered this the optimal balance between accuracy and assessment burden. The platform was perceived to improve clinical communication and facilitate shared decision-making. CONCLUSIONS: Our platform is likely to facilitate routine CLEFT-Q uptake, and this may have a positive impact on clinical care. Our free source code enables other researchers to rapidly and economically reproduce this work for other PROMs.

Impact of Completing FACE-Q Craniofacial Module Scales on Children and Young Adults with Facial Differences: An International Study.

BACKGROUND: The FACE-Q Craniofacial Module measures outcomes that matter to patients with diverse craniofacial conditions. However, it is not known whether completing a patient-reported outcome measure (PROM) has a negative impact on patients, particularly children. This study aims to investigate the impact of completing the FACE-Q Craniofacial Module and identify factors associated with a negative impact. METHODS: Participants were between 8 and 29 years of age, had a facial difference, and completed at least one module of the FACE-Q Craniofacial Module as part of the international field-test study between December of 2016 and 2019. Participants were asked three questions: "Did you like or dislike answering this questionnaire?" "Did answering these questions change how you feel about how you look?" and "Did answering this questionnaire make you feel unhappy or happy?" Univariate and multivariable logistic regression analyses were used to evaluate variables associated with a negative response. RESULTS: The sample included 927 participants. Most patients responded neutrally to all impact questions: 42.7% neither disliked nor liked the questionnaire; 76.6% felt the same about how they looked; and 72.7% felt neither unhappy nor happy after completion. Negative responses represented a small proportion of patients across all three impact questions (<13.2%). Increased craniofacial severity, more scales completed, and lower scores on all FACE-Q scales were associated with negative responses for all three impact questions ( P <0.01). CONCLUSIONS: This study provides evidence that the FACE-Q Craniofacial Module is acceptable for most participants. Clinicians and study investigators should follow up with patients after completing this PROM to address areas of concern in scale scores. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Psychometric Validation of the FACE-Q Craniofacial Module for Facial Nerve Paralysis.

Background: Systematic reviews have identified the need for a patient-reported outcome measure for facial nerve paralysis (FNP). The aim of this study was to determine the psychometric properties of FACE-Q Craniofacial module scales when used in a combined sample of children and older adults with FNP. Methods: Data were collected between December 2016 and December 2019. We conducted qualitative interviews with children and adults with FNP. FACE-Q data were collected from patients aged 8 years and older with FNP. Rasch measurement theory analysis was used to examine the reliability and validity of the relevant scales in the FNP sample. Results: Twenty-five patients provided 2052 qualitative codes related to appearance, physical, psychological, and social function. Many patient concerns were common across age. The field-test sample included 235 patients aged 8-81 years. Of the 13 scales examined, all 122 items had ordered thresholds and good item fit to the Rasch model. For 12 scales, person separation index values were ≥0.79 and Cronbach's alpha values were ≥0.82. The 13th scale's reliability values were ≥0.71. Conclusion: The FACE-Q Craniofacial module scales described in this study can be used to collect and compare evidence-based outcome data from children and adults with FNP.

Deeper Understanding of Appearance in Orofacial Clefts: A Structural Equation Model of the CLEFT-Q Appearance Scales.

BACKGROUND: The CLEFT-Q is a patient-reported outcome measure with seven scales measuring elements of facial appearance in cleft lip and/or palate. We built on the validated CLEFT-Q structural model to describe conceptual relationships between these scales, and tested our hypothesis through structural equation modeling (SEM). In our hypothesized model, the appearance of the nose, nostrils, teeth, jaw, lips, and cleft lip scar all contribute to overall facial appearance. METHODS: We included 640 participants from the international CLEFT-Q field test. Model fit was assessed using weighted least squares mean and variance adjusted regression. The model was then refined through modification indices. The fit of the hypothesized model was confirmed in an independent sample of 452 participants. RESULTS: The refined model demonstrated excellent fit to the data (comparative fit index 0.999, Tucker-Lewis index 0.999, root mean square error of approximation 0.036 and standardized root mean square residual 0.036). The confirmatory analysis also demonstrated excellent model fit. CONCLUSION: Our structural model, based on a clinical understanding of appearance in orofacial clefting, aligns with CLEFT-Q field test data. This supports the instrument's use and the exploration of a wider range of applications, such as multidimensional computerized adaptive testing.

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.

Recursive Partitioning vs Computerized Adaptive Testing to Reduce the Burden of Health Assessments in Cleft Lip and/or Palate: Comparative Simulation Study.

BACKGROUND: Computerized adaptive testing (CAT) has been shown to deliver short, accurate, and personalized versions of the CLEFT-Q patient-reported outcome measure for children and young adults born with a cleft lip and/or palate. Decision trees may integrate clinician-reported data (eg, age, gender, cleft type, and planned treatments) to make these assessments even shorter and more accurate. OBJECTIVE: We aimed to create decision tree models incorporating clinician-reported data into adaptive CLEFT-Q assessments and compare their accuracy to traditional CAT models. METHODS: We used relevant clinician-reported data and patient-reported item responses from the CLEFT-Q field test to train and test decision tree models using recursive partitioning. We compared the prediction accuracy of decision trees to CAT assessments of similar length. Participant scores from the full-length questionnaire were used as ground truth. Accuracy was assessed through Pearson's correlation coefficient of predicted and ground truth scores, mean absolute error, root mean squared error, and a two-tailed Wilcoxon signed-rank test comparing squared error. RESULTS: Decision trees demonstrated poorer accuracy than CAT comparators and generally made data splits based on item responses rather than clinician-reported data. CONCLUSIONS: When predicting CLEFT-Q scores, individual item responses are generally more informative than clinician-reported data. Decision trees that make binary splits are at risk of underfitting polytomous patient-reported outcome measure data and demonstrated poorer performance than CATs in this study.

Establishing content validity of an orthodontic subset of the FACE-Q Craniofacial Module in children and young adults with malocclusion.

OBJECTIVE: The FACE-Q Craniofacial Module for children and young adults is a patient-reported outcome measure (PROM) designed to measure outcomes for patients aged 8 to 29 years with facial conditions. The aim of this study was to establish content validity of a relevant subset of the module for its use in orthodontic patients with malocclusion. SETTING AND SAMPLE POPULATION: Experts in orthodontics were emailed and invited to provide feedback through a Research Electronic Data Capture survey. Patient feedback was obtained through cognitive interviews with patients aged 8 to 29 years recruited from a university-based orthodontic clinic in Canada. MATERIALS AND METHODS: Expert opinion and patient interviews were used to obtain feedback on the content of 4 appearance (face, smile, teeth and jaws) and 1 function (eating and drinking) scales hypothesized to be relevant to orthodontic malocclusions, and to elicit new concepts. Interviews were audio-recorded, transcribed, and coded using a line-by-line approach. RESULTS: Twenty-one experts and 15 patients participated. Expert feedback led us to drop 9, retain 40, revise 4 and add 16 new items. At the conclusion of cognitive interviews no items were dropped, 55 were retained, 5 were revised and 8 new items were added. The final set of 68 items demonstrated content validity for orthodontic patients. CONCLUSION: Expert feedback and cognitive interviews enabled us to revise and refine 5 scales as part of the FACE-Q Craniofacial Module for use in orthodontic patients. These scales were included in the internationalfield-test of the FACE-Q Craniofacial Module.

An international study to develop the EAR-Q patient-reported outcome measure for children and young adults with ear conditions.

BACKGROUND: There is currently a lack of patient-reported outcome measures for ear reconstruction. We developed the EAR-Q to measure ear appearance and post-operative adverse effects from the patient perspective. METHODS: Field-test data were collected from children and young adults in eight countries between 13 May 2016 and 12 December 2019. Rasch measurement theory (RMT) analysis was used to refine the scales and to examine their psychometric properties. RESULTS: Participants had microtia (n = 607), prominent ears (n = 145) or another ear condition (n = 111), and provided 960 assessments for the Appearance scale (e.g., size, shape, photos), and 137 assessments for the Adverse Effects scale (e.g., itchy, painful, numb). RMT analysis led to the reduction of each scale to 10-items. Data fit the Rasch model for the Appearance (X2(80) = 90.9, p = 0.19) and Adverse Effects (X2(20) = 24.5, p = 0.22) scales. All items in each scale had ordered thresholds and good item fit. There was no evidence of differential item function for the Appearance scale by age, gender, language, or type of ear condition. Reliability was high for the Appearance scale, with person separation index (PSI) and Cronbach alpha values with and without extremes ≥0.92. Reliability for the Adverse Effects scale was adequate (i.e., PSI and Cronbach alpha values ≥0.71). Higher scores (liked appearance more) correlated with higher scores (better) on Psychological, Social and School scales. INTERPRETATION: The EAR-Q can be used in those 8-29 years of age to understand the patient perspective in clinical practice and research, and in addition, can be used to benchmark outcomes for ear reconstruction internationally.

Optimising the computerised adaptive test to reliably reduce the burden of administering the CLEFT-Q: A Monte Carlo simulation study.

BACKGROUND: Computerised adaptive testing (CAT) has the potential to transform plastic surgery outcome measurement by making patient-reported outcome measures (PROMs) shorter, individualised and more accurate than pen-and-paper questionnaires. OBJECTIVES: This paper reports the results of two optimisation studies for the CLEFT-Q CAT, a CAT intended for use in the field of cleft lip and/or palate. Specifically, we aimed to identify the optimal score estimation and item selection methods for using this CAT in clinical practice. These represent two major components of any CAT algorithm. METHOD: Monte Carlo simulations were performed using simulated data in the R statistical computing environment and incorporated a range of score estimation and item selection techniques. The performance and accuracy of the CAT was assessed by mean items administered, correlation between CAT scores and paired linear assessment scores, and the root mean squared deviation (RMSD) of these score pairs. RESULTS: The accuracy of the CLEFT-Q CAT was not significantly affected by the choice of score estimation or item selection method. Sub-scales which originally contain more items were amenable to greater item reduction with CAT. CONCLUSION: This study shows that score estimation and item selection methods that need minimal processing power can be used in the CLEFT-Q CAT without compromising accuracy. This means that the CLEFT-Q CAT could be administered quickly and efficiently with basic hardware demands. We recommend the use of less computationally intensive techniques in future CLEFT-Q CAT studies.
