Objective: Craniofacial microsomia (CFM) is a broad clinical term used to describe a congenital condition most commonly involving the underdevelopment of the external ear, mandible, soft tissues, and facial nerve. Despite medical advances, understanding of the psychological health and healthcare experiences of individuals with CFM and their caregivers remains limited. This article describes a research program designed to address these knowledge gaps, and identify opportunities for psychosocial intervention and improved healthcare provision.

Background: The CLEFT-Q, a questionnaire developed and validated specifically for cleft patients, contains seven appearance scales. The International Consortium of Health Outcomes Measurement (ICHOM) has incorporated only some CLEFT-Q appearance scales in the Standard Set to minimize burden. This study evaluates which appearance scales provide the most meaningful information in the different cleft types at specific ages, for the most efficient cleft appearance outcome assessment.

Background: To ensure the feasibility of implementing PROMs in clinical practice, they must be continually appraised for undue burden placed on patients and clinicians and their usefulness for decision-making. This study assesses correlations between the CLEFT-Q psychosocial scales in the International Consortium for Health Outcomes Measurement Standard Set for cleft and explores their associations with patient characteristics and psychosocial care referral.

Methods: Spearman correlation coefficients were calculated for CLEFT-Q psychological function, social function, school function, face, speech function, and speech-related distress scales.

Purpose: Mismatch between preoperative planning and surgical outcome in maxillofacial surgery relate to on-table replication of presurgical planning and predictive algorithm inaccuracy: software error was hereby decoupled from planning inaccuracy to assess a commercial software. The hypothesis was that soft tissue prediction error would be minimized if the surgical procedure was replicated precisely as planned and is independent of the extent of bone repositioning.

Materials And Methods: Cone-beam computed tomography scans of 16 Le Fort I osteotomy patients were collected at Boston Children's Hospital.

A visible difference to the face or body may challenge adolescents' adjustment and engagement in life activities, where some require psychosocial support. However, evidence is limited for whether existing interventions for this adolescent group reduce social or appearance-related distress. We therefore conducted a parallel-group, randomised control trial to evaluate the effectiveness of Young Person's Face IT, a self-guided web-based psychosocial intervention developed for adolescents with a visible difference who experience distress.

The aim of the study was to investigate whether different head shapes show different volumetric changes following spring-assisted posterior vault expansion (SA-PVE) and to investigate the influence of surgical and morphological parameters on SA-PVE. Preoperative three-dimensional skull models from patients who underwent SA-PVE were extracted from computed tomography scans. Patient head shape was described using statistical shape modelling (SSM) and principal component analysis (PCA).
