Abstract
The study aimed to summarize current knowledge regarding the use of orthopaedic functional appliances (OFA) in managing unilateral craniofacial microsomia (UCM). The eligibility criteria for the review were (1) assessing use of OFA as a stand-alone treatment and (2) using OFA in combination during or after MDO. The PICO (population, intervention, comparison and outcome) format formulated clinical questions with defined inclusion and exclusion criteria. No limitations concerning language and publication year were applied. Information sources: A literature search of Medline, Scopus, Embase, Cochrane Central Register of Controlled Trials, Web of Science databases without restrictions up to 30 September 2022. The risk of bias was assessed. According to Cochrane and PRISMA guidelines, two independent authors conducted data extraction. The level of evidence for included articles was evaluated based on the Oxford evidence-based medicine database. Due to the heterogeneity of studies and insufficient data for statistical pooling, meta-analysis was not feasible. Therefore, the results were synthesized narratively. A total of 437 articles were retrieved. Of these, nine met inclusion criteria: five assessing OFA and four assessing OFA during or after MDO. There is limited evidence to suggest that stand-alone and combination treatment with OFA is beneficial for treating mild-to-moderate UCM-related dentofacial deformities in short term. No studies assessed the burden of care. In the management of UCM, there is insufficient evidence supporting the efficacy of OFA as a stand-alone treatment or when combined with MDO. Additionally, there is a lack of evidence regarding treatment protocols and the effect on the condyles and the TMJ. The study was registered at Prospero database number CRD42020204969.

J Pediatr Nurs 2024:S0882-5963(24)00178-7. [PMID: 38729894 DOI: 10.1016/j.pedn.2024.04.053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 04/06/2024] [Accepted: 04/28/2024] [Indexed: 05/12/2024]
Abstract
PURPOSE Craniofacial microsomia (CFM) is a congenital condition that can be associated with feeding challenges in infants. As part of the larger 'Craniofacial microsomia: Accelerating Research and Education (CARE)' program, this study described caregivers' early feeding experiences. DESIGN AND MATERIALS US-based caregivers of 34 children with CFM participated in remote narrative interviews. Two authors completed inductive thematic analysis in an iterative process until consensus was reached. RESULTS Caregivers' narratives outlined the inherent challenges of feeding an infant with special healthcare needs. The first theme 'Navigating Challenges and Managing Expectations' describes the distress participants experienced when they were unable to breastfeed and the negative emotional effect of switching to formula. The second theme 'Making Adaptations' outlines the methods participants tried, including breast pumps and feeding tubes. The third theme 'Accessing Support' describes participants' interactions with healthcare providers and challenges accessing feeding support. The final theme 'Growing from Adversity' recounts participants' relief once their child established a feeding pattern and the personal growth gained from their experiences. CONCLUSIONS Caregivers reported several feeding related challenges associated with CFM, many of which negatively affected their wellbeing. Negative consequences were particularly pronounced in cases where caregivers' feeding experiences differed from their expectations. Participants identified challenges in accessing reliable feeding information and support. Despite difficult experiences, caregivers cited some positive outcomes, including increased confidence and resilience. PRACTICE IMPLICATIONS Holistic feeding information and support for families affected by CFM should be inclusive of several feeding methods to improve care delivery, child health, and the caregiver experience.

Abstract
OBJECTIVE To assess which information about microtia and the possible reconstructive options health care providers (HCPs), patients and parents believe should be included in a patient decision aid (PtDA). DESIGN A mixed-methods study comprised of an online survey of HCPs and focus group discussions with patients and parents. PARTICIPANTS Survey respondents were members of the International Society for Auricular Reconstruction (ISAR). Focus group participants were patients with microtia and their parents, recruited through the microtia outpatient clinic at Amsterdam UMC, and through a Dutch patient organization for cleft and craniofacial conditions. METHODS An online, investigator-made survey was sent to ISAR members in December 2021. Semi-structured focus group discussions were held in February 2022. Quantitative results were summarized, and qualitative results were thematically grouped. RESULTS Thirty-two HCPs responded to the survey (response rate 41%). Most respondents (n = 24) were plastic surgeons, who had a median of 15 years of experience (IQR: 7-23 years). Two focus groups were held with a total of five patients and two parents. HCPs, patients and parents generally agreed on the information needed in a PtDA, emphasizing the importance of realistic expectation management. Patients and parents also considered psychosocial and functional outcomes, patient experiences, as well as patients' involvement in decision-making important. CONCLUSIONS A PtDA for microtia reconstruction should target all patients with microtia, and include information on at least technique-related information, expected esthetic results, possible adverse effects, psychosocial and functional outcomes and patient experiences. Preference eliciting questions should be developed for both pediatric patients and their parents.

Abstract
INTRODUCTION Craniofacial microsomia (CFM) is a complex congenital condition primarily affecting the ear, mandible, facial nerve and muscles, and tongue. Individuals with CFM are at increased risk of hearing loss, obstructive sleep apnea, and feeding/swallowing difficulties. The purpose of this scoping review was to summarize evidence pertaining to speech production in CFM. METHOD All articles reporting any characteristic of speech production in CFM were included and screened by two independent reviewers by title, abstract, and full text. Data charting captured details related to study population and design, CFM diagnostic criteria, speech outcome measurement, and key findings. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews checklist guided reporting of results. Our protocol was registered on the Open Science Framework (https://osf.io/npr94/) and published elsewhere. RESULTS Forty-five articles were included in the detailed review. Most articles originated from the United States, were published in the past decade, and utilized case report/series study design. A speech-language pathologist authored 29%. The prevalence of velopharyngeal insufficiency ranged from 19% to 55% among studies. Oral distortion of alveolar and palatal fricatives and affricates primarily characterized articulation errors. Studies identified increased disordered speech and lower intelligibility in adolescents with CFM compared to unaffected peers. Evidence pertaining to phonatory and respiratory speech findings is limited. CONCLUSIONS Evidence supports that individuals with CFM are at increased risk of both velopharyngeal and articulatory speech differences. Additional information is needed to develop speech screening guidelines for children with CFM. Heterogeneity in study design and outcome measurement precludes comparisons across studies.

Abstract
The goals of this study were to investigate the incidence and characteristics of hematuria in patients with microtia, and to clarify that more attention should be paid to renal dysfunction in patients with microtia. We conducted a retrospective cohort study of a total 9447 children diagnosed with microtia (selected as study group, 7037 children) or pigmented nevus (selected as control group, 2410 children) at the Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from January 2009 to June 2021. All of the routine urinalysis report of these children were reviewed to assess the incidence and characteristics of hematuria in each group. No statistically significant differences were observed when analyzing the overall incidence of hematuria between the study and control groups (P > 0.05). However, after grouping by sex, the incidence of hematuria in female children with microtia was significantly higher than that in femalecontrol group and no similar results were observed in the male patients. In addition, after further grouping by age in case group, the incidence of hematuria in girls of all ages with microtia was significantly higher than that in males with microtia (age 0-10:males: Girls = 1.89%:4.14%; age 0-5: males: Girls = 1.22%:3.73%; age 6-10: males:Girls = 1.97%:4.14%,P < 0.05), while no similar results were obtained in the control group.(age 0-10:males: Girls = 1.39%:2.22%; age 0-5: males: Girls = 1.07%:1.95%; age 6-10: males: Girls = 3.38%:3.17%, P > 0.05). Higher incidence of hematuria was observed in female children with microtia.

Abstract
This paper describes 20 years of microtia and craniofacial microsomia (CFM) psychosocial and healthcare studies and suggests directions for clinical care and research. A narrative review of papers January 2000 to July 2021 related to psychosocial and healthcare experiences of individuals with microtia and CFM and their families. Studies (N = 64) were mainly cross-sectional (69%), included a range of standardized measures (64%), and were with European (31%), American (27%), or multinational (23%) samples. Data were generally collected from both patients and caregivers (38%) or patient self-report (35%). Sample sizes were 11 to 25 (21%), 26 to 50 (19%), 51 to 100 (22%), or over 100 (38%). Studies addressed 5 primary topics: (1) Healthcare Experiences, including Medical Care, Hearing Loss/Amplification, Diagnostic Experiences, and Information Preferences; (2) Psychosocial Experiences, including Teasing, Behavioral Adjustment, Psychosocial Support, and Public Perception; (3) Neurocognitive Functioning and Academic Assistance; (4) Pre- and Post-Operative Psychosocial Outcomes of Ear Reconstruction/Canaloplasty; and (5) Quality of Life and Patient Satisfaction. Care involved multiple specialties and was often experienced as stressful starting at diagnosis. Psychosocial and neurocognitive functioning were generally in the average range, with possible risk for social and language concerns. Coping and resiliency were described into adulthood. Satisfaction and positive benefit of ear reconstruction/canaloplasty were high. Care recommendations include increasing: hearing amplification use, microtia and CFM knowledge among providers, efficient treatment coordination, psychosocial support, academic assistance, and advances to minimize surgical scarring. This broad literature overview informs clinical practice and research to improve psychosocial outcomes.

Abstract
To (1) appraise current international classification and clinical management strategies for craniofacial microsomia (CFM) and microtia, and (2) to assess agreement with the European Reference Network "European Guideline Craniofacial Microsomia" recommendations on screening and monitoring. This was a cross-sectional online survey study. The survey consisted of 44 questions on demographics, diagnostics and classification, obstructive sleep apnea, feeding difficulties, speech and language development, hearing, ocular abnormalities, visual development, orthodontic screening, genetic counselling, psychological wellbeing, and extracraniofacial anomalies. Respondents were participants of 3 international cleft and craniofacial conferences, members of the American Cleft Palate and Craniofacial Association and members of the International Society for Auricular Reconstruction. Respondents were requested to complete 1 questionnaire per multidisciplinary team. Fifty-seven responses were received from 30 countries (response rate ∼3%).The International Consortium for Health Outcomes Measurement diagnostic criteria were used by 86% of respondents, though 65% considered isolated microtia a mild form of CFM. The Orbit, Mandible, Ear, Facial Nerve and Soft Tissue classification system was used by 74% of respondents. Agreement with standardized screening and monitoring recommendations was between 61% and 97%. A majority of respondents agreed with screening for extracraniofacial anomalies (63%-68%) and with genetic counselling (81%). This survey did not reveal consistent agreement on the diagnostic criteria for CFM. Respondents mostly supported management recommendations, but frequently disagreed with the standardization of care. Future studies could focus on working towards international consensus on diagnostic criteria, and exploring internationally feasible management strategies.

Hospitalizations from Birth to 28 Years in a Population Cohort of Individuals Born with Five Rare Craniofacial Anomalies in Western Australia. J Pediatr 2023; 259:113418. [PMID: 37030611 DOI: 10.1016/j.jpeds.2023.113418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 03/29/2023] [Accepted: 03/31/2023] [Indexed: 04/10/2023]
Abstract
OBJECTIVE To describe trends, age-specific patterns, and factors influencing hospitalizations for 5 rare craniofacial anomalies (CFAs). METHODS Data on livebirths (1983-2010; n = 721 019) including rare CFA (craniofacial microsomia, mandibulofacial dysostosis, Pierre Robin sequence, Van der Woude syndrome, and frontonasal dysplasia), episodes of death, and demographic and perinatal factors were identified from the Western Australian Register of Developmental Anomalies, Death Registrations and Midwives Notification System. Information on incident craniofacial and noncraniofacial related admissions, length of hospital stay, and intensive care and emergency-related admissions were identified using principal diagnosis and procedural codes were extracted from the Hospital Morbidity Data Collection and linked to other data sources. Associations of hospitalizations by age groups as well as demographic and perinatal factors were expressed as incidence rate ratio (IRR). RESULTS The incident hospitalizations were 3 times as high for rare CFA (IRR 3.22-3.72) throughout childhood into adolescence than those without. Children with rare CFA had 3-4 times as many potentially preventable hospitalizations until 18 years of age than those without. Specifically, respiratory infections (IRR 2.13-2.35), ear infections (IRR 7.92-26.28), and oral health-related conditions contributed for most noncraniofacial admissions until the adolescence period. A greater incidence of noncraniofacial related hospitalizations was observed among Indigenous children, births with intrauterine growth restrictions, and families with high socioeconomic disadvantage. CONCLUSIONS Throughout childhood, individuals with rare CFA had greater hospital service use, specifically for potentially preventable conditions, than those without. These population-level findings can inform new preventive strategies and early disease management targeted toward reducing preventable hospitalizations.

Abstract
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. DESIGN The Craniofacial microsomia: Accelerating Research and Education (CARE) research program aims to: 1) Conduct up to 160 narrative interviews with individuals and caregivers to validate a conceptual framework; 2) Administer an online international survey of up to 800 individuals with CFM and caregivers to identify predictors of psychological distress; 3) Perform up to 60 semi-structured interviews with healthcare providers and advocacy leaders to examine the extent to which current healthcare provisions address identified patient needs; and 4) Establish a participant registry to build a longitudinal database and develop an international community. RESULTS Teams in the USA and UK have been established, alongside an international, interdisciplinary Advisory Committee. Data analysis for Aim 1 is ongoing and informing the delivery of Aims 2-3. Aim 4 is also in development. A dedicated website serves as a recruitment tool, educational resource, and mechanism for engaging with the CFM community. CONCLUSIONS The CARE program provides a comprehensive approach to understanding the experiences of individuals with CFM and their caregivers. Challenges encountered and lessons learned are shared for the benefit of the community.

Abstract
INTRODUCTION Asymmetric mandibular hypoplasia, microtia, tongue and laryngeal anomalies, and soft palate and facial nerve dysfunction are clinical features observed in children with craniofacial microsomia (CFM). Despite involvement of all these structures in hearing and speech, there is limited evidence reporting speech outcomes in this population. Systematic reviews of clinical and surgical interventions related to CFM have been published, but no methodological review of speech outcomes exists. This scoping review will summarise what is known about speech production in individuals with CFM as well as illustrate gaps in the existing body of literature that will guide future research. METHODS/ANALYSIS This review will follow the methodological framework for scoping reviews first reported by Arksey & O'Malley and revised by Levac and others. Databases searched will include Ovid MEDLINE, EMBASE, CINAHL, PsycINFO and grey literature. Articles reporting any parameter of speech production in individuals with CFM will be considered for inclusion. Articles published in a language other than English will be excluded. Articles will be screened in three stages: (1) title review, (2) abstract review and (3) full text review. Ten per cent of articles will be rescreened by a second reviewer. Reference lists will be hand reviewed to identify additional relevant articles. Data charting will capture article metadata, study population and design, CFM diagnostic criteria, speech outcome measurement and key findings. The Preferred Reporting Systems for Systematic Reviews and Meta-Analyses Protocols-Extension for Scoping Reviews checklist will guide reporting of results. Descriptive analysis and data visualisation strategies will be used. ETHICS AND DISSEMINATION Institutional review board approval is not required for a scoping review, as it does not directly involve human subjects. Results will be disseminated through peer-reviewed publication as well as conference presentation.

Use of a Fibula Free Flap for Mandibular Reconstruction in Severe Craniofacial Microsomia in Children with Obstructive Sleep Apnea. J Clin Med 2023; 12:jcm12031124. [PMID: 36769772 PMCID: PMC9917725 DOI: 10.3390/jcm12031124] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 01/17/2023] [Accepted: 01/28/2023] [Indexed: 02/04/2023] Open
Abstract
This is a retrospective study describing a multi-stage protocol for the management of severe mandibular hypoplasia in craniofacial microsomia (CFM) with accompanying obstructive sleep apnea (OSA). Patients with severe mandibular hypoplasia require reconstruction functionality and esthetical features. In the cohort, reconstructions based on free fibular flaps (FFF) may be the most effective way. Patients aged 4-17 years with severe mandibular hypoplasia were treated with FFF, which initially improved the respiratory function assessed on polysomnography (AHI). In the next stages of treatment of cases with respiratory deterioration, it was indicated to perform distraction osteogenesis (DO) of the mandible and the structures reconstructed with FFF. All surgeries were planned in accordance with virtual surgery planning VSP. The aim of the study was to prospectively assess the effectiveness of multi-stage mandibular reconstruction in craniofacial microsomia with the use of a free fibula flap in terms of improving respiratory failure due to obstructive sleep apnea (OSA). The FFF reconstruction method, performed with virtual surgical planning (VSP), is proving to be an effective alternative to traditional methods of mandibular reconstruction in patients with severe CFM with OSA.

Abstract
BACKGROUND Mandibular distraction osteogenesis is effective for the correction of severe tongue-based airway obstruction in infants with Pierre Robin sequence. Involved osteotomies may damage developing tooth buds and/or the inferior alveolar nerve. The authors evaluated the theoretical safety of various osteotomy techniques to better define infantile mandibular anatomy using computer-aided modeling. METHODS Seven mandibular osteotomy techniques (oblique, inverted-L, multiangular, walking stick, high oblique, vertical/high inverted-L, and horizontal) were simulated using computed tomography studies from infants with Pierre Robin sequence and without other associated conditions. Software was used to manually segment the mandibular bone, inferior alveolar nerve, and tooth buds. RESULTS Sixty-five computed tomography scans were included, yielding 130 hemimandibles. The horizontal osteotomy pattern had significantly lower theoretical risk of tooth bud (p < 0.001) and inferior alveolar nerve involvement (p < 0.001) than all other patterns. Osteotomies with high vertical components (i.e., vertical, walking stick, and multiangular) had lower theoretical tooth bud involvement than the more proximal oblique and inverted-L osteotomies (p < 0.001). Average lingula location was measured at a point 65 percent of the mandibular width from anterior mandibular border and 63 percent of the mandibular height from the inferior mandibular border. CONCLUSIONS Surgical planning with computed tomography scans can help evaluate an infant's mandibular anatomy to select an osteotomy that reduces morbidity risks. Regardless of technique, tooth buds and the inferior alveolar nerve are often included in osteotomies. The lingula location in this study demonstrates a position more superior and posterior than that previously described. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, V.

Abstract
Background: Hemifacial microsomia (HFM), which involves multiple sites with different levels of severity, is the second most common congenital craniofacial deformity after cleft lip and palate. However, three-dimensional (3D) measurements of mandibular deformities have not yet been studied in detail. The objective of this study is to investigate the method of 3D measurements of mandibular deformities in HFM patients. Methods: A total of 48 HFM patients were included in this study. All clinical treatment for patients was performed in the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences at Peking Union Medical College from June 2006 to June 2020. The patients’ 3D computerized tomography scan data were processed using medical imaging software, following four iterative steps: 3D reconstruction, mirroring, differential analysis, and partition. Results: The characteristics of the mandibular bone in HFM patients are mainly presented as follows: (1) compared to the normal side, the part of the bone body that extends from the ascending ramus to the pogonion (Po-NB) is analyzed using a dynamic process: less fullness-fullness-more fullness; (2) absences were frequently observed among the angular zones, that is, the height of the ascending ramus is deficient. Conclusions: HFM is a complicated condition with numerous variations in clinical presentation. We employed both 3D image reconstruction and computerization image processing techniques to investigate asymmetrical mandibular deformity in HFM patients in detail and with great accuracy. This will be of great use to clinicians for disease management.

Proposed clinical approach and imaging studies in families with oculo-auriculo-vertebral spectrum to assess variable expressivity. Am J Med Genet A 2022; 188:1515-1525. [PMID: 35119197 DOI: 10.1002/ajmg.a.62678] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 12/03/2021] [Accepted: 01/03/2022] [Indexed: 11/11/2022]
Abstract
A diagnosis of oculo-auriculo-vertebral spectrum (OAVS) is established when microtia is present in association with hemifacial hypoplasia (HH) and/or ocular, vertebral, and/or renal malformations. There is no consensus on which imaging studies should be used to rule out variable expressivity and distinguish "sporadic" from "familial" patients. This observational and descriptive study was performed in a Mexican population of 51 patients (32 males, 19 females, 0-18 years old) with microtia/OAVS, and their available parents. A clinical history, genealogy, and physical examination were obtained from all included patients, as were a computed tomography (CT) scan of the ear, audiological evaluation, orthopantomography, complete spine radiography, and renal ultrasound. The same approach was completed in their available parents (51 mothers and 40 fathers), excluding the CT scan and audiological evaluation. By genealogy, 53% of patients were classified as "sporadic"; of the "familial" patients, at least 79.1% had suggestion of a multifactorial inheritance. In the available parents, orthopantomography, complete spine X-ray, and renal ultrasound identified the following OAVS-related manifestations: HH (16.2%, n = 14/86), vertebral alterations (10.9%, n = 10/91), and renal anomalies (2.2%, n = 2/90). Our evaluation of the parents allowed three patients to be reclassified from "sporadic" to "familial" (5.8%, n = 3/51). Our proposed clinical and imaging approach allowed the identification of variable expressivity that more clearly distinguished between "sporadic" and "familial" OAVS patients, which is of utmost importance in providing proper genetic counseling to these families.

Abstract
ABSTRACT Children with craniofacial microsomia (CFM) are at increased risk for educational and social concerns. This study describes intervention services and frequency of teasing in a multinational population of children with CFM. Caregivers of children with CFM ages 3 to 18 years in the US and South America were administered a questionnaire. Additional information was gathered from medical charts and photographs. Participants (N = 169) had an average age of 10.1 ± 6.2 years, were primarily male (60%), and from the US (46%) or Colombia (32%). Most participants had microtia and mandibular hypoplasia (70%). They often had unilateral (71%) or bilateral (19%) hearing loss and 53% used a hearing aid. In the US, special education services were provided for 48% of participants enrolled in school; however, similar services were rare (4%) in South America and reflect differences in education systems. Access to any intervention service was higher in the US (80%) than in South America (48%). Caregivers reported children showed diagnosis awareness by an average age of 4.4 ± 1.9 years. Current or past teasing was reported in 41% of the children, starting at a mean age of 6.0 ± 2.4 years, and most often took place at school (86%). As half of the US participants received developmental and academic interventions, providers should screen for needs and facilitate access to services. Given diagnosis awareness at age 4 and teasing at age 6, providers are encouraged to assess for psychosocial concerns and link to resources early in treatment.

Abstract
This study aims to discuss diagnostic criteria and severity assessment for craniofacial microsomia (CFM). A series of 61 patients with diverse CFM phenotypes had their clinical data collected by experienced dysmorphologists using a single protocol. Genetic abnormalities were searched through karyotype and chromosomal microarray analysis. Sex ratio, prenatal risk factors, and recurrence rate corroborated the literature. Despite the wide variability of clinical findings, ear disruption was universal. Eight patients were assigned as syndromic, four of whom had demonstrable genetic alterations. The majority of patients (67.2%) fulfilled four known diagnostic criteria, while 9.8% fulfilled one of them. Data strengthened disruptions of the ear and deafness as a semiotically valuable sign in CFM. Facial impairment should consider asymmetry as a mild expression of microsomia. Spinal and cardiac anomalies, microcephaly, and developmental delay were prevalent among extra craniofacial features and should be screened before planning treatment and follow up. The severity index was able to recognize the less and the most affected patients. However, it was not useful to support therapeutic decisions and prognosis in the clinical scenario due to syndromic and non-syndromic phenotypes overlapping. These issues make contemporary the debate on diagnostic methods and disease severity assessment for CFM. They also impact care and etiopathogenetic studies.

Abstract
This article provides an overview of rare orbital diseases. Congenital
malformations, inflammatory diseases, benign and malignant neoplasias are
described. Although it represents a relatively small area of the body the
orbit contains multiple different tissues. Therefore, a great variety of
diseases can be found within the orbital space. That is the reason, why both
the completeness and the level of detail in the description of particular
diseases must be somewhat limited. Nevertheless, clinical manifestations,
important aspects of diagnosis, treatment strategies, and, when specific
data are available, the prognosis are described. The authors tried to
highlight the most characteristic aspects of the different diseases to
describe their relevant aspects in spite of the brevity of the
subsections.

Abstract
ABSTRACT Patients with craniofacial microsomia often require multiple surgical interventions to address both hard and soft tissue defects. For improvement of soft tissue defects, microvascular free tissue transfers have been widely performed after puberty. To camouflage facial asymmetry, early fat grafting was performed on five six-month-old patients, and acceptable outcomes were obtained without overcorrection. This result suggests that early fat grafting in craniofacial microsomia is useful to camouflage asymmetrical facial contours.

Abstract
Objective To investigate the treatment modalities (Tx-Mods) for patients with unilateral hemifacial microsomia (UHFM) according to Pruzansky–Kaban types and growth stages. Methods The samples consisted of 82 Korean UHFM patients. Tx-Mods were defined as follows Tx-Mod-1, growth observation due to mild facial asymmetry; Tx-Mod-2, unilateral functional appliance; Tx- Mod-3, fixed orthodontic treatment; Tx-Mod-4, growth observation due to a definite need for surgical intervention; Tx-Mod-5, unilateral mandibular or bimaxillary distraction osteogenesis (DO); Tx-Mod-6, maxillary fixation using LeFort I osteotomy and mandibular DO/sagittal split ramus osteotomy; Tx- Mod-7, orthognathic surgery; and Tx-Mod-8, costochondral grafting. The type and frequency of Tx-Mod, the number of patients who underwent surgical procedures, and the number of surgeries that each patient underwent, were investigated. Results The degree of invasiveness and complexity of Tx-Mod increased, with an increase in treatment stage and Pruzansky–Kaban type (initial < final; [I, IIa] < [IIb, III], all p < 0.001). The percentage of patients who underwent surgical procedures increased up to 4.2 times, with an increase in the Pruzansky–Kaban type (I, 24.1%; IIa, 47.1%; IIb, 84.4%; III, 100%; p < 0.001). However, the mean number of surgical procedures that each patient underwent showed a tendency of increase according to the Pruzansky–Kaban types (I, n = 1.1; IIa, n = 1.5; IIb, n = 1.6; III, n = 2.3; p > 0.05). Conclusions These findings might be used as basic guidelines for successful treatment planning and prognosis prediction in UHFM patients.

Abstract
OBJECTIVES To: (1) design an artifact-free 3D-printed MR-safe temporary transfer device, (2) engineer bone-pins from carbon fiber reinforced polyether ether ketone (CFR-PEEK), (3) evaluate the imaging artifacts of CFR-PEEK, and (4) confirm the osteointegration potential of CFR-PEEK, thus enhancing 3D-planning of bony advancements in hemifacial microsomia using sequential magnetic resonance imaging (MRI). STUDY DESIGN Engineered CRF-PEEK bone pins and a 3D printed ex-fix device were implanted into a sheep head and imaged with MRI and computed tomography . The osseointegration and bony compatibility potential of CFR-PEEK was assessed with scanning electron microscopy images of MC3T3 preosteoblast cells on the surface of the material. RESULTS The CFR-PEEK pins resulted in a signal void equivalent to the dimension of the pin, with no adjacent areas of MR-signal loss or computed tomography artifact. MCT3 cells adhered and proliferated on the surface of the discs by forming a monolayer of cells, confirming compatibility and osseointegration potential. CONCLUSION A 3D printed transfer device could be utilized temporarily during MRI to permit artifact-free 3D planning. CFR-PEEK pins eliminate imaging artifact permitting sequential MRI examination. In combination, this has the potential to enhance distraction osteogenesis, by permitting accurate three-dimensional planning without ionizing radiation.

Abstract
OBJECTIVES Microtia is a congenital ear anomaly that hinders quality of life. Microtia patients, both syndromic and in isolation, may be at-risk for significant renal anomalies that can go undetected at the time of birth. The goal of this study was to characterize the prevalence of renal anomalies among microtia patients at our institution in order to guide optimal patient management. Current guidelines suggest performing a renal ultrasound when there is presence of preauricular pits and ear anomalies in association with dysmorphic features, but not in cases of isolated microtia and atresia. DESIGN A retrospective review of 237 children with microtia was conducted from 2001 through 2018 at our tertiary-care pediatric institution, of which 98 also had a documented renal ultrasound. Patients were identified as syndromic or non-syndromic. Data endpoints included renal ultrasounds performed, structural anomalies found, and follow-up. RESULTS Among the 237 patients, 98 had received renal ultrasounds. 12% of the total cohort was found to be syndromic, the most common being Goldenhar. Structural anomalies were detected in 24% of the 98 patients that underwent ultrasound and included disorders such as pelviectasis, renal ectopia, duplicated collecting systems, and renal agenesis. A third of patients with anomalies required follow-up with nephrology for chronic kidney disease or renal failure. Of note, 21% of non-syndromic patients and 43% of syndromic patients screened had an abnormality on ultrasonography. CONCLUSIONS Children with microtia are at a significant risk of structural renal abnormalities, even when isolated outside of a genetic syndrome. We recommend the strong consideration of performing a screening renal ultrasound in all patients with microtia. Prospective data would be helpful in developing future clinical guidelines regarding the utility of screening ultrasonography.

Abstract
Mandibular distraction osteogenesis at an early age is the standard hemifacial microsomia treatment. Nevertheless, the recurrence rate remains high and the definition of early age is controversial. We explored the optimal timing for mandibular distraction, when the surrounding skeleton, such as maxilla, can grow compensatory, to reduce recurrence. Hemifacial microsomia patients were prospectively divided into Groups A (1-3 years old) and B (4-6 years old), according to maxillary and mandibular growth curves. Computed tomography scans were obtained before distractor implantation and after removal surgery. Maxillary volume increase percentage was the main outcome indicator; other indicators (maxillary symmetry and complications) were secondary outcomes. Fifty-eight patients were enrolled and all but one patient in Group A (failed distraction) completed the study. Two patients had facial nerve injury and another two had mouth-opening limitation, which was relieved after coracoid resection. The difference in percentage increase in maxillary volume between the affected and unaffected sides was 5.06 ± 2.73% and 3.18 ± 1.99% in Groups A and B, respectively, suggesting better compensatory growth in younger patients (P = 0.004). Maxillary symmetry was apparently elevated after mandibular distraction. Mandibular distraction osteogenesis was confirmed to be feasible and safe at age <4 years.

Orthod Craniofac Res 2019; 22 Suppl 1:163-167. [PMID: 31074142 DOI: 10.1111/ocr.12259] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2018] [Revised: 12/19/2018] [Accepted: 12/04/2018] [Indexed: 02/06/2023]
Abstract
OBJECTIVE Craniofacial microsmia is the second most common congenital disorder with mostly unilateral defects of ear, temporomandibular joint, mandible, and muscles of facial expression and mastication. The objective of this study was to identify, if there were any, de novo germline or somatic variants in a patient with Occulo-Auriculo-Vertebral Spectrum (OAVS) using whole-exome sequencing. SETTINGS AND SAMPLE POPULATION Trio/Family-based study of an OAVS proband. MATERIALS AND METHODS Children's Mercy Hospital Institutional Review Board approved this study and a request-to-rely was procured from the University of Missouri Kansas City IRB. Informed assent/consent was obtained for all family members prior to any research activities. The peripheral blood/affected side tissues from corrective surgery of the proband and peripheral blood samples from unaffected parents were collected. The isolated genomic DNA were enriched for exomes and sequenced on an Illlumina HiSeq 2500 instrument yielding paired-end 125 nucleotide reads (84X coverage). Gapped alignment to reference sequences (GRCh37.p5) was performed with BWA and the GATK and analysis completed using custom-developed software. RESULTS Analyses revealed that the proband carried a de novo germ line nonsense substitution (c.901C>T) in AMIGO2 gene, and missense substitutions in ZCCHC14 (c.1198C>T), and in SZT2 genes (c.2951C>T). CONCLUSIONS The nonsense substitution in AMIGO2 gene introduces a premature stop codon possibly rendering the gene non-functional via nonsense-mediated pathway decay-therefore considered a stronger candidate. Further functional studies are required to confirm whether loss-of-function variants in AMIGO2 can cause OAVS.

Abstract
Congenital heart diseases are a common prenatal finding. The prenatal identification of an associated genetic syndrome or a major extracardiac anomaly helps to understand the etiopathogenic diagnosis. Besides, it also assesses the prognosis, management, and familial recurrence risk while strongly influences parental decision to choose termination of pregnancy or postnatal care. This review article describes the most common genetic diagnoses associated with a prenatal finding of a congenital heart disease and a suggested diagnostic process.

[PMID: 30903854 PMCID: PMC6430716 DOI: 10.1016/j.ijscr.2019.03.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Revised: 02/08/2019] [Accepted: 03/07/2019] [Indexed: 12/18/2022] Open
Abstract
INTRODUCTION, Hemifacial microsomia is the second most common craniofacial congenital anomaly. It corresponds to a group of malformations ranging from minimal facial asymmetry to sever form affecting mandible, soft tissues, orbit, ear, and cranial nerves. PRESENTATION OF CASE, We present a case of 6 years old patient with Kaban class III hemifacial microsomia with anotia. Temporomandibular joint was reconstructed by costochondral graft using computer guided surgery (simulation and rapid prototyping). A computer guided soft tissue guide, mandibular, and maxillomandibular/zygomatic models were constructed using rapid prototyping technology. The customized computer guided soft tissue guide was used to localize the proper position of skin incision, the mandibular model was used for preoperative reconstruction plate bending, and the maxillomandibular/zygomatic model was used to estimate the rib graft length and position. Postoperative assessment showed proper positioning of the graft, with no complications or facial nerve affection. DISCUSSION, In this report, we introduce a new computer guided technique to estimate and identify the proper position of the temporomandibular joint graft based on patient CT. This technique eliminated the need of extended incisions with excessive dissection and provided a more accessible field for rib graft fixation, facilitating the surgical procedures. CONCLUSION, The use of computer guided surgery (simulation and rapid prototyping) for temporomandibular joint reconstruction in Kaban III hemifacial microsomia with anotia facilitates the surgical procedure, minimizes procedure time, increases precision, and reduces possible complications.

Abstract
OBJECTIVE The Craniofacial microsomia: Longitudinal Outcomes in Children pre-Kindergarten (CLOCK) study is a longitudinal cohort study of neurobehavioral outcomes in infants and toddlers with craniofacial microsomia (CFM). In this article, we review the data collection and methods used to characterize this complex condition and describe the demographic and clinical characteristics of the cohort. SETTING Craniofacial and otolaryngology clinics at 5 study sites. PARTICIPANTS Infants with CFM and unaffected infants (controls) ages 12 to 24 months were recruited from the same geographical regions and followed to age 36 to 48 months. METHODS Phenotypic, neurodevelopmental, and facial expression assessments were completed during the first and third waves of data collection (time 1 and time 3, respectively). Medical history data were taken at both of these time points and during an intermediate parent phone interview (time 2). RESULTS Our cohort includes 108 cases and 84 controls. Most cases and controls identified as white and 55% of cases and 37% of controls identified as Hispanic. Nearly all cases had microtia (95%) and 59% had mandibular hypoplasia. Cases received extensive clinical care in infancy, with 59% receiving care in a craniofacial clinic and 28% experiencing at least one surgery. Study visits were completed at a study site (92%) or at the participant's home (8%). CONCLUSIONS The CLOCK study represents an effort to overcome the challenges of characterizing the phenotypic and neurodevelopmental outcomes of CFM in a large, demographically and geographically diverse cohort.

Abstract
PURPOSE OF REVIEW Oculo-auriculo-vertebral spectrum (OAVS) is a complex disorder that is represented by wide variations in phenotypic presentation. Recent publications and systematic reviews of the available literature are presented here. RECENT FINDINGS Treatment strategies vary among craniofacial centers across the country. Advances in presurgical planning, virtual surgical planning, and computer-aided manufacturing have been incorporated in the treatment of patients. The psychosocial effect of OAVS with longitudinal follow-up is now being studied. SUMMARY Optimal evaluation and management of the OAVS patient requires an awareness of the phenotypic and genetic differences and involves a multidisciplinary team in order to effectively and appropriately diagnose and treat such patients.

Abstract
This study describes stressors, resources, and recommendations related to craniofacial microsomia (CFM) care from the perspective of caregivers of children with CFM and adults with CFM to inform improved quality of healthcare delivery. A mixed method design was used with fixed-response and open-ended questions from an online survey in English. The survey included demographics, CFM phenotypic information, and items about CFM-related experiences across settings. Themes were identified by qualitative analysis of responses to open-ended questions. Respondents (n = 51) included caregivers (n = 42; 90% mothers) and adults with CFM (n = 9; 78% female), who had a mean age of 45 ± 6 years. Most children were male (71%) with an average age of 7 ± 4 years. Respondents were primarily white (80%), non-Hispanic (89%), from the United States (82%), had a college degree (80%), and had private health insurance (80%). Reflecting the high rate of microtia (84%) in the sample, themes centered on the impact of hearing difficulties across settings with related language concerns. Negative social experiences were frequently described and school needs outlined. Multiple medical stressors were identified and corresponding suggestions included: providers need to be better informed about CFM, treatment coordination among specialists, and preference for a family-centered approach with reassurance, empathy, and clear communication. Advice offered to others with CFM included positive coping strategies. Overall, caregivers' and patients' responses reflected the complexity of CFM treatment. Incorporating these perspectives into routine CFM care has the potential to reduce family distress while improving their healthcare.

Renal ultrasound abnormalities in children with syndromic and non-syndromic microtia. Int J Pediatr Otorhinolaryngol 2018; 113:173-176.

Abstract
OBJECTIVE Renal abnormalities are commonly considered in the work up of pediatric patients with external ear malformations. However, there is little consensus regarding an appropriate renal screening protocol for patients with microtia. We sought to characterize renal abnormalities detected on ultrasonography in pediatric patients with microtia. METHODS We conducted a retrospective cohort study of pediatric patients diagnosed with microtia who underwent renal ultrasound from 1991 to 2014 at a single tertiary academic institution. Renal ultrasound reports and medical records were reviewed to assess for renal abnormalities and to determine whether patients required specialist follow-up or interventions. Audiograms and otolaryngology notes were used to determine patterns of hearing loss. The following additional information was recorded from the electronic medical records: patient sex, microtia grade (I-IV), microtia laterality, and known associated syndromes. Characteristics were compared between those who did and did not have renal ultrasound findings using Fisher's exact test. Univariate logistic regression analysis was performed to determine factors associated with renal ultrasound findings. RESULTS The majority of patients in this cohort were syndromic (n = 51, 64%) with grade III microtia (n = 46, 58%) and conductive hearing loss (n = 58, 72%). Syndromic children with microtia demonstrated a higher crude rate of renal ultrasound abnormalities (22%) than children with isolated microtia (7%). Of these patients, 69% required specialist follow-up. Univariate logistic regression analysis did not identify predictors that were significantly associated with renal ultrasound findings. CONCLUSION Fairly high rates of abnormalities in syndromic and non-syndromic patients may warrant screening renal ultrasound in all patients with microtia, especially given the high percentage of findings requiring renal follow-up. A prospective study to formally evaluate screening efficacy is needed.

Abstract
Objective The objective of this study was to determine whether patients with isolated microtia or aural atresia have an increased prevalence of renal or cervical vertebral anomalies. Design The study design was a retrospective medical record review. Setting The setting was the following four distinct institutions: an urban tertiary care children's hospital, two urban academic medical centers, and a staff-model health maintenance organization. Participants Patients diagnosed with microtia, aural atresia, or oculoauriculovertebral spectrum were identified. Patients with facial asymmetry, craniofacial microsomia, and other craniofacial abnormalities or syndromes were excluded. Main Outcome Measures Main outcome measures were the number of patients with isolated microtia or aural atresia who underwent a renal ultrasound or cervical spine X-ray, the results of those studies, and further evaluation or treatment for any abnormalities found. Statistical Analysis A binomial analysis using a one-sided 95% confidence level was performed. Results A total of 514 patients with isolated microtia and/or aural atresia were identified. Of these patients, 145 (28%) had undergone a renal ultrasound and 81 (16%) had undergone cervical spine X-rays. A total of 3 patients (2%) had minimal renal pelviectasis, all of which had resolved on repeat ultrasound and required no treatment. There were no structural renal abnormalities identified, and there were no cervical spine abnormalities identified. Conclusions The data suggest that there is no increased prevalence of structural renal or cervical vertebral anomalies in patients with isolated microtia and/or aural atresia. Therefore, these patients do not require routine screening renal ultrasound or cervical spine X-rays.

Abstract
OBJECTIVE To investigate the deformations of temporal bone and mandible combined with congenital aural atresia. METHODS A total of 158 patients with congenital aural atresia were included in the study. The raw CT data of the temporal bone was imported into MIMICS v 12 and threshold dissection, region growing and three-dimensional (3D) calculation were used to calculate 3D models. The 3D characteristics of the temporal bone and upper part of mandible were assessed. RESULTS The tympanic part of the temporal bone was all undeveloped. Of all the patients included, 14 patients were found to have severe maxillofacial malformations. Among them, 2 cases have floating arch, 4 cases have interrupted arch, 5 cases have mandibular processes hypoplasia and 3 cases have interrupted arch combined with severe maxillary malformation. Ten of the 14 patients were suffered from dysplasia of the mastoid part of the temporal bone as well. CONCLUSION Maxillofacial malformations may sometimes coexist with congenital aural atresia. Otolaryngologists should not neglect the coexisted maxillofacial malformations and give timely referral to maxillofacial surgeons.

Abstract
The aim of this study was to compare the anatomical differences in the skull base between the affected and non-affected side in patients with craniofacial microsomia (CFM), and to compare the affected and non-affected sides with measurements from a normal population. Three-dimensional computed tomography scans of 13 patients with unilateral CFM and 19 normal patients (age range 7-12 years) were marked manually with reliable homologous landmarks. Principal component analysis (PCA), as part of a point distribution model (PDM), was used to analyse the variability within the normal and preoperative CFM patient groups. Through analysis of the differences in the principal components calculated for the two groups, a model was created to describe the differences between CFM patients and normal age-matched controls. The PDMs were also used to describe the shape changes in the skull base between the cohorts and validated this model. Using thin-plate splines as a means of interpolation, videos were created to visualize the transformation from CFM skull to normal skull, and to display the variability in shape changes within the groups themselves. In CFM cases, the skull base showed significant asymmetry. Anatomical areas around the glenoid fossa and mastoid process showed the most asymmetry and restriction of growth, suggesting a pathology involving the first and second pharyngeal arches.

Abstract
Reconstructing auricular deformities for bilateral microtia is a demanding challenge especially after failed autologous reconstruction. This case report presents a novel application of virtual surgical planning, computer-assisted design, and intraoperative surgical navigation to preplan and execute placement of custom-tailored silicone auricular prostheses and titanium osseointegrated implants for a bone-anchored hearing aid system in a patient with Treacher Collins syndrome in whom autologous reconstruction had previously failed. Through a collaborative approach between the reconstructive surgeon and anaplastologist, the implementation of advanced digital technologies may offer a superior esthetic and functional outcome to patients with previously failed reconstruction.

Abstract
Background: The limited cranial skin covering auricular implants is an important yet underrated factor in auricular reconstruction for both reconstruction surgery and tissue engineering strategies. We report exact measurements on skin deficiency in microtia patients and propose an accessible preoperative method for these measurements. Methods: Plaster ear models (n = 11; male:female = 2:1) of lobular-type microtia patients admitted to the University Medical Center Utrecht in The Netherlands were scanned using a micro-computed tomographic scanner or a cone-beam computed tomographic scanner. The resulting images were converted into mesh models from which the surface area could be calculated. Results: The mean total skin area of an adult-size healthy ear was 47.3 cm2, with 49.0 cm2 in men and 44.3 cm2 in women. Microtia ears averaged 14.5 cm2, with 15.6 cm2 in men and 12.6 cm2 in women. The amount of skin deficiency was 25.4 cm2, with 26.7 cm2 in men and 23.1 cm2 in women. Conclusions: This study proposes a novel method to provide quantitative data on the skin surface area of the healthy adult auricle and the amount of skin deficiency in microtia patients. We demonstrate that the microtia ear has less than 50% of skin available compared with healthy ears. Limited skin availability in microtia patients can lead to healing problems after auricular reconstruction and poses a significant challenge in the development of tissue-engineered cartilage implants. The results of this study could be used to evaluate outcomes and investigate new techniques with regard to tissue-engineered auricular constructs.

Abstract
BACKGROUND To report autologous free fat grafting as an isolated procedure to manage facial contour asymmetry of a subset of growing patients with craniofacial microsomia (CFM). METHODS A retrospective analysis of CFM patients (n = 11) with low socioeconomic and intellectual status, poor oral hygiene, living far from our center, Pruzansky-Kaban I/II mandibles, without functional concerns, and with no craniofacial skeletal surgery who underwent isolated free fat grafting between 2012 and 2013 was conducted. Surgeon and parent/patient satisfaction were elicited. Computerized photogrammetric quantitative and qualitative facial symmetry analyses were performed. RESULTS All patients underwent isolated autologous free fat grafting to restore the facial contour symmetry. Surgeon and patient/parent were mostly satisfied. There were significant (all P < 0.05) postoperative quantitative facial symmetry enhancement and an overall qualitative facial symmetry enhancement. CONCLUSIONS A significant improvement of facial symmetry was obtained in this subset of growing CFM patients using only isolated free fat grafting.

Abstract
Microtia is a genetic condition affecting the external ears and presents clinically along a wide spectrum: minimally affected ears are small with minor shape abnormalities; extremely affected ears lack all identifiable structures, with the most extreme being absence of the entire external ear. Multiple genetic causes have been linked to microtia in both animal models and humans, which are improving our understanding of the condition and may lead to the identification of a unified cause for the condition. Microtia is also a prominent feature of several genetic syndromes, the study of which has provided further insight into the possible causes and genetic mechanisms of the condition. This article reviews our current understanding of microtia including epidemiological characteristics, classification systems, environmental and genetic causative factors leading to microtia. Despite our increased understanding of the genetics of microtia, we do not have a means of preventing the condition and still rely on complex staged, surgical correction.

Abstract
INTRODUCTION Disordered craniofacial development frequently results in definitive facial asymmetries that can significantly impact a person's social and functional well-being. The mandible plays a prominent role in defining facial symmetry and, as an active region of growth, commonly acquires asymmetric features. Additionally, syndromic mandibular asymmetry characterizes craniofacial microsomia (CFM), the second most prevalent congenital craniofacial anomaly (1:3000 to 1:5000 live births) after cleft lip and palate. We hypothesized that asymmetric rates of mandibular growth occur in the context of syndromic and acquired facial asymmetries. METHODS To test this hypothesis, a spherical harmonic-based shape correspondence algorithm was applied to quantify and characterize asymmetries in mandibular growth and remodeling in 3 groups during adolescence. Longitudinal time points were automatically registered, and regions of the condyle and posterior ramus were selected for growth quantification. The first group (n = 9) had a diagnosis of CFM, limited to Pruzansky-Kaban type I or IIA mandibular deformities. The second group (n = 10) consisted of subjects with asymmetric, nonsyndromic dentofacial asymmetry requiring surgical intervention. A control group (n = 10) of symmetric patients was selected for comparison. A linear mixed model was used for the statistical comparison of growth asymmetry between the groups. RESULTS Initial mandibular shape and symmetry displayed distinct signatures in the 3 groups (P <0.001), with the greatest asymmetries in the condyle and ramus. Similarly, mandibular growth had unique patterns in the groups. The dentofacial asymmetry group was characterized by significant asymmetry in condylar and posterior ramal remodeling with growth (P <0.001). The CFM group was characterized by asymmetric growth of the posterior ramus (P <0.001) but relatively symmetric growth of the condyles (P = 0.47). CONCLUSIONS Forms of CFM are characterized by active and variable growth of the dysplastic side, which has a distinct pattern from other disorders of mandibular growth.

Abstract
OBJECTIVE To investigate the relationship between the severity of ear anomaly and mandibular dysplasia in congenital microtia. STUDY DESIGN Retrospective case review. SETTING Sapporo Medical University Hospital. PATIENTS Congenital microtia: 44 patients over a period of 4 years. INTERVENTIONS The height of the condylar process of the mandible was assessed by three-dimensional computed tomography (CT), and the patients were divided into three groups based on the ratio of the condylar process height on the affected side to that on the unaffected side: Group A, ≥1.00; Group B, 0.99 to 0.85; Group C, <0.85. Developmental abnormalities of the ear were evaluated using Jahrsdoerfer's scoring system on high-resolution CT scans. MAIN OUTCOME MEASURES Nonparametric statistical tests were used to determine correlations between the height of the condylar process of the mandible and Jahrsdoerfer's score. RESULTS The total Jahrsdoerfer's score for each group was 7.36 ± 2.23, 7.28 ± 0.10, and 4.52 ± 0.30, respectively; this value was significantly lower in Group C than in the other groups. In terms of subtotal points, oval window open, middle ear aeration, and mastoid pneumatization correlated significantly with mandibular dysplasia. Patients in Group C tended to have grade III microtia, by Marx's classification. Facial nerve weakness was not significantly correlated with mandibular dysplasia. CONCLUSIONS In congenital microtia, mandibular development correlated significantly with aeration of the middle ear space, pneumatization of the mastoid, and formation of the oval window, but not with the presence of a bony part of the external auditory canal or with ossicular development.

Abstract
Craniofacial development is a complex morphogenic event that relies on highly orchestrated interactions between multiple cell types. Since the first description of Meckel’s cartilage in the lower jaw more than 180 years ago, we have come to realize that expansion of this specialized structure underpins correct mandible development. Here we demonstrate that an intricate association between neural crest cells and blood vessels plays an important role in promoting chondrocyte proliferation and expansion of Meckel’s cartilage as a prerequisite of correct mandibular morphogenesis. These findings provide direct insight into the origins and potential treatments of highly prevalent disorders affecting the mandible. Jaw morphogenesis depends on the growth of Meckel’s cartilage during embryogenesis. However, the cell types and signals that promote chondrocyte proliferation for Meckel’s cartilage growth are poorly defined. Here we show that neural crest cells (NCCs) and their derivatives provide an essential source of the vascular endothelial growth factor (VEGF) to enhance jaw vascularization and stabilize the major mandibular artery. We further show in two independent mouse models that blood vessels promote Meckel’s cartilage extension. Coculture experiments of arterial tissue with NCCs or chondrocytes demonstrated that NCC-derived VEGF promotes blood vessel growth and that blood vessels secrete factors to instruct chondrocyte proliferation. Computed tomography and X-ray scans of patients with hemifacial microsomia also showed that jaw hypoplasia correlates with mandibular artery dysgenesis. We conclude that cranial NCCs and their derivatives provide an essential source of VEGF to support blood vessel growth in the developing jaw, which in turn is essential for normal chondrocyte proliferation, and therefore jaw extension.
