[Oesophageal Atresia - from the Challenge in Prenatal Medicine until Surgical Care]. / Die Ösophagusatresie ­ von der Herausforderung in der Pränatalmedizin bis zur chirurgischen Versorgung.

Oesophageal atresia causes a dysplasia of the oesophagus with or without a connection to the adjoining trachea. Prenatal ultrasound results are not specific enough to confirm a suspected diagnosis. In addition to polyhydramnios and a small or absent stomach, the so-called "pouch sign" reinforces the suspected diagnosis. An MRI increases the prenatal detection rate. Due to the lack of reliable sonografic markers, ultrasonic testing is advised during pregnancy. Particularly, further causes for the polyhydramnios should be categorically excluded. Postnatally, children present with classic symptoms. Surgical treatment results in a very high quality of life and a very good prognosis. Nevertheless lifelong monitoring and follow-up of the patient is required.

Epidermal Nevi and Related Syndromes -- Part 1: Keratinocytic Nevi. / Nevus epidérmicos y síndromes relacionados. Parte 1: nevus queratinocíticos.

Epidermal nevi are hamartomatous lesions derived from the epidermis and/or adnexal structures of the skin; they have traditionally been classified according to their morphology. New variants have been described in recent years and advances in genetics have contributed to better characterization of these lesions and an improved understanding of their relationship with certain extracutaneous manifestations. In the first part of this review article, we will look at nevi derived specifically from the epidermis and associated syndromes.

Vascular Anomalies (Part I): Classification and Diagnostics of Vascular Anomalies.

BACKGROUND: Vascular anomalies are a diagnostic and therapeutic challenge. They require dedicated interdisciplinary management. Optimal patient care relies on integral medical evaluation and a classification system established by experts in the field, to provide a better understanding of these complex vascular entities. METHOD: A dedicated classification system according to the International Society for the Study of Vascular Anomalies (ISSVA) and the German Interdisciplinary Society of Vascular Anomalies (DiGGefA) is presented. The vast spectrum of diagnostic modalities, ranging from ultrasound with color Doppler, conventional X-ray, CT with 4 D imaging and MRI as well as catheter angiography for appropriate assessment is discussed. RESULTS: Congenital vascular anomalies are comprised of vascular tumors, based on endothelial cell proliferation and vascular malformations with underlying mesenchymal and angiogenetic disorder. Vascular tumors tend to regress with patient's age, vascular malformations increase in size and are subdivided into capillary, venous, lymphatic, arterio-venous and combined malformations, depending on their dominant vasculature. According to their appearance, venous malformations are the most common representative of vascular anomalies (70 %), followed by lymphatic malformations (12 %), arterio-venous malformations (8 %), combined malformation syndromes (6 %) and capillary malformations (4 %). CONCLUSION: The aim is to provide an overview of the current classification system and diagnostic characterization of vascular anomalies in order to facilitate interdisciplinary management of vascular anomalies. KEY POINTS: · Vascular anomalies are comprised of vascular tumors and vascular malformations, both considered to be rare diseases.. · Appropriate treatment depends on correct classification and diagnosis of vascular anomalies, which is based on established national and international classification systems, recommendations and guidelines.. · In the classification, diagnosis and treatment of congenital vascular anomalies, radiology plays an integral part in patient management..

Sanjad-Sakati Syndrome: Oral Health Care.

OBJECTIVES: The aim of this report is to describe the orofacial manifestations and dental management of a girl with Sanjad-Sakati syndrome. CLINICAL PRESENTATION AND INTERVENTION: The facial features included microcephaly, thin lips, beaked nose, low set ears, and a retrognathic mandible. An oral examination revealed oligodontia/hypodontia, small dental arches, a high arched palate, and a deep overbite and increased overjet. Oral rehabilitation involved full coverage prosthetic crowns on the upper central incisors, stainless steel crowns on the lower molars, and removable partial prostheses to replace missing teeth. CONCLUSION: Recognition of orofacial features might help in the diagnosis of Sanjad-Sakati syndrome. Dental management of affected patients might be complicated by intellectual, neurological, and endocrine abnormalities.

Phenotypic spectrum of Tessier facial cleft number 5.

INTRODUCTION: Craniofacial clefts belong to the most disfiguring and rare congenital malformations of the face and among these, orbito-facial clefts constitute approximately 0.22 % of the cases with Tessier cleft number 5 being the least common. Our aim was to define the phenotypic spectrum for this subgroup to improve clinical management. METHODS: Our study group consisted of four patients which were treated at two different cleft centers. Retrospective chart review and anatomical analysis were conducted for each patient based on clinical evaluation and imaging studies. Morphological anomalies including soft tissue, bone and oral components were recorded. RESULTS: Based on our analysis and literature review, we could define two subtypes of Tessier facial cleft number 5. (1) Medial clefts are the more severe subtype, creating a significant soft tissue and bone defect that runs vertically, through the eyelid, infraorbital rim, maxillary sinus and cheek. They have the poorer esthetic and functional prognosis, due to orbital dystopia and absence of lower eyelid. (2) Lateral clefts are a less severe subtype characterized by the presence of a vertical furrow of the cheek running laterally to the maxillary sinus. CONCLUSIONS: We identified two subtypes of facial cleft number 5 which require an individualized surgical management.

[Update on the treatment of RASopathies]. / Actualizacion del tratamiento de las rasopatias.

INTRODUCTION: The term 'RASopathies' covers a series of diseases that present mutations in the genes that code for the proteins of the RAS/MAPK pathway. These diseases include neurofibromatosis type 1, Noonan syndrome, Legius syndrome, LEOPARD syndrome, Costello syndrome and cardiofaciocutaneous syndrome. Involvement of the RAS/MAPK pathway not only increases predisposition to develop tumours, but also determines the presence of phenotypic anomalies and alterations in learning processes. AIM: To review the use of therapeutic strategies with mechanisms that have a selective action on RASopathies. DEVELOPMENT: The fact that the RAS pathway is involved in a third of all neoplasms has led to the development and study of different drugs at this level. Some of these pharmaceutical agents have been tested in RASopathies, mainly in neurofibromatosis type 1. Here we analyse the use of different antitarget treatments: drugs that act on the membrane receptors, such as tyrosine kinase inhibitors, in the mTOR pathway or MEK inhibitors. These latter have shown potential benefits in recent studies conducted on different RASopathies. CONCLUSIONS: Today, thanks to the results from the first studies conducted with MEK inhibitor based mainly on animal models, a number of promising clinical trials are being carried out.

TITLE: Actualizacion del tratamiento de las rasopatias.Introduccion. El termino 'rasopatias' agrupa una serie de enfermedades que presentan mutaciones en genes que codifican las proteinas de la via RAS/MAPK. Estas enfermedades incluyen la neurofibromatosis de tipo 1, el sindrome de Noonan, el sindrome de Legius, el sindrome LEOPARD, el sindrome de Costello y el sindrome cardiofaciocutaneo. La afectacion de la via RAS/MAPK no solo aumenta la predisposicion a desarrollar tumores, sino que tambien determina la presencia de anomalias fenotipicas y alteraciones en los procesos de aprendizaje. Objetivo. Revisar el papel del uso de estrategias terapeuticas con mecanismos de accion selectivo en las rasopatias. Desarrollo. El hecho de que la via RAS participe en un tercio de las neoplasias ha motivado el desarrollo y el estudio de distintos farmacos a este nivel. Algunos de estos farmacos han sido probados en las rasopatias, principalmente en la neurofibromatosis de tipo 1. Analizamos el uso de distintos tratamientos antidiana: farmacos que actuan en los receptores de membrana, como los inhibidores de la tirosincinasa, en la via mTOR o los inhibidores de MEK. Existe un potencial beneficio de estos ultimos en estudios recientes realizados en distintas rasopatias. Conclusiones. Actualmente, gracias a los resultados de los primeros trabajos desarrollados con inhibidor de MEK basados principalmente en modelos animales, se estan realizando multiples ensayos clinicos prometedores.

CITED2 Mutations in Conserved Regions Contribute to Conotruncal Heart Defects in Chinese Children.

Conotruncal heart defects (CTDs) are severe malformations of outflow tract with heterogeneous morphology. Several missense variants of CITED2 have been identified to cause CTDs in recent researches. In this study, we screened the coding regions of CITED2 in 605 Chinese children with CTDs and found two possible pathogenic mutant sites: p.Q117L and p.T257A, both located in the conserved regions of CITED2. Then, we investigated the biological and functional alterations of them. Western blotting showed low level of protein expression of mutant Q117 and T257A compared with wild-type CITED2. Dual-luciferase reporter assay demonstrated that mutant Q117 and T257A decreased the ability of CITED2 to modulate the expression of paired-like homeodomain transcription factor 2 gamma (PITX2C), which are closely related to cardiac growth and left-right patterning. Meanwhile, T257A also exhibited impaired ability to mediate vascular endothelial growth factor expression, another gene closely associated with the normal development of cardiovascular system. Three-dimensional molecular conformation showed reduced hydrogen bond between Asp254 and mutant Thr257, indicating the weakened stability and binding ability of CITED2. All these results suggest that CITED2 mutations in conserved regions lead to disease-causing biological and functional changes and may contribute to the occurrence of CTDs.

Prevalence of Semicircular Canal Hypoplasia in Patients With CHARGE Syndrome: 3C Syndrome.

Importance: CHARGE syndrome refers to a syndrome involving coloboma, heart defects, atresia choanae, retardation of growth and development, genitourinary disorders, and ear anomalies. However, Verloes revised the characteristics of CHARGE syndrome in 2005 to define this syndrome more broadly. Deficiency of the semicircular canals is now a major criterion for CHARGE syndrome. Objective: To characterize patients with CHARGE syndrome at our center using Verloes' criteria and to reevaluate the nomenclature for this condition. Design, Setting, and Participants: We performed a medical chart review of patients with CHARGE syndrome and reviewed their temporal bone imaging studies at a tertiary care children's hospital affiliated with Washington University in St Louis. Two authors independently reviewed each imaging study (A.W. and K.H.). Radiologic studies, physical findings, genetic tests, and other diagnostic tests were included. Patients with no temporal bone imaging studies were excluded. Results: Eighteen children were included in this study; 13 children (72%) were male, and the mean (median; range) age of patients at the time of inner ear imaging studies was 2 years (4.5 years; 8 months to 8 years). Coloboma was present in 13 patients (72%) and choanal atresia in 5 (28%); semicircular canal anomalies were present in all patients. Additionally, 13 patients (72%) were diagnosed as having hindbrain anomalies, 17 (94%) as having endocrine disorders, 17 (94%) as having mediastinal organ malformations, and all as having middle or external ear abnormalities and development delay. Cleft lip and cleft palate were found in 6 of 14 patients (43%) who did not have choanal atresia. We tested 16 patients for mutations in the CHD7 gene; 10 were positive (63%) for mutations, 4 (25%) were negative, and 2 (13%) were inconclusive. Conclusions and Relevance: Semicircular canal anomalies were the most consistent finding in our patients with CHARGE syndrome. Given the high prevalence of semicircular canal hypoplasia and importance of imaging for diagnosing CHARGE syndrome, we propose changing the term CHARGE syndrome to 3C syndrome to emphasize the importance of the semicircular canals and to recall the 3 major criteria for diagnosis: coloboma, choanal atresia, and semicircular canal anomaly. The nomenclature would also reference the 3 semicircular canals in each ear. This new name for CHARGE syndrome would provide a mnemonic and focus the disease on the most important clinical criteria for diagnosis.

Management of Lip Pits in Van der Woude Syndrome: A Clinical Classification With Difficulty Index.

PURPOSE: Numerous case reports have been published on lip pits in Van der Woude syndrome explaining the morphology and genetics in detail; however, thus far, no article has focused on the classification of lip pits as an aid in surgical management. Although the procedure for lip pits in Van der Woude syndrome appears straightforward, even in the best of hands, the excision can be very challenging with no guarantee of esthetically desirable results. Therefore, we have devised a classification based on a difficulty index in the management of lower lip pits to assist in predicting the treatment outcome before surgery, as well as to offer the choice of a particular technique in a specific situation. MATERIALS AND METHODS: We reviewed 19 cases of Van der Woude syndrome having lower lip pits that were operated on at our unit from May 2005 to June 2015 with a minimum follow-up of at least 6 months. The data analyzed included the patient's age and gender, location of the lip pits with regard to their proximity to the white skin roll, number of lip pits, presurgical depth of the lip pits, and discharge of mucous secretion from the pits, as well as timing of lip pit excision. Four techniques of excision were performed via routine excision, modified routine excision, vertical wedge excision, and inverted-T lip reduction. The data were tabulated and analyzed. On the basis of our experience in managing lip pits, a clinically relevant classification with a difficulty index was then proposed. RESULTS: Among the 12 patients having preoperative involvement of the white skin roll, 8 had distortion of the white skin roll when operated on by either routine excision (n = 2), modified routine excision (n = 3), or inverted-T lip reduction (n = 3). The remaining 4 patients had no distortion of the white skin roll after surgery when the vertical wedge excision technique was performed. The 7 patients who had no distortion of the white skin roll preoperatively presented with esthetic results when operated on by either the routine excision, modified routine excision, or inverted-T lip reduction technique. In 2 patients with a presurgical pit depth greater than 6 mm, mucocele formation was observed after surgery. Using the data obtained, we proposed a classification based on 2 parameters: involvement of the white skin roll and presurgical depth. A difficulty index also was proposed using these same variables. CONCLUSIONS: Classification and evaluation of the difficulty of lip pit excision are essential in planning the surgical treatment to give improved esthetic results. This proposed classification and difficulty index will provide the operating surgeon with a standardized scheme to evaluate the difficulty of the excision as well as to predict the overall outcome of the procedure before surgery.

Environmental needs in childhood disability analysed by the WHO ICF, Child and Youth Version.

INTRODUCTION: The WHO has launched a common classification for disabilities in children, the International Classification of Functioning, Disability and Health, Child and Youth Version (ICF-CY). We wanted to determine whether cat-egories of the environmental (e) and the body functions (b) components of the classification could address environmental needs in children with different disorders and various disability severities. METHODS: A set of 16 e categories and 47 b categories were selected and worded to best enable parents to describe children's everyday support needs and environmental influences through interviews in their own homes. RESULTS: Of the 367 invited parents, 332 (90.5%) participated, providing data on children with spina bifida, spinal muscular atrophy, muscular disorders, cerebral palsy, visual impairments, hearing impairments, mental disability and disabilities following brain tumour treatment. The mean age of children across disabilities was 9.4 years (range: 1.0-15.9). The mean e code score was 35.7 (range: 4.0-64.0), and the mean b code score was 32.2 (range: 0.0-159.0). The most urgent needs as detected by qualifier 4 environmental categories scores were common among children with complex disorders and issues related to health professionals, legal services and health services. CONCLUSIONS: Parents understand the environmental and body function components in a meaningful manner and the codes seem to be valid. Special emphasis should be given to environmental issues for children with more complex disabilities. There was no correlation between the severity of a disability and environmental issues, indicating that each child's needs were basically met, irrespective of disability severity.

Functional Outcome of Anorectal Malformations and Associated Anomalies in Era of Krickenbeck Classification.

OBJECTIVE: To describe the management and functional outcome of anorectal malformations and associated anomalies according to Krickenbeck classification. STUDY DESIGN: Case series. PLACE AND DURATION OF STUDY: The Aga Khan University Hospital, Karachi, from January 2002 to December 2012. METHODOLOGY: Anorectal anomalies were classified according to Krickenbeck classification. Data was collected and proforma used regarding the primary disease associated anomalies, its management and functional outcome, according to Krickenbeck classification. Cases included were: all those children with imperforate anus managed during the study period. Qualitative variables like gender and functional outcome were reported as frequencies and percentages. Quantitative variables like age were reported as medians with interquartile ranges. RESULTS: There were 84 children in study group. Most common associated anomaly was cardiac (38%), followed by urological anomaly (33%). All children were treated by Posterior Sagittal Anorectoplasty (PSARP). Fistula was present in 64 out of 84 (76%) cases. The most common fistula was rectourethral (33%), followed by recto vestibular (31%). According to Krickenbeck classification, continence was achieved in 62% children; however 27% children were constipated, followed by 12% children having fecal soiling. CONCLUSION: Functional outcome of anorectal malformation depends upon severity of disease. A thorough evaluation of all infants with ARM should be done with particular focus on cardiovascular (38%) and genitourinary abnormalities (33%).

Tracheobronchial Branching Abnormalities: Lobe-based Classification Scheme.

Boyden's nomenclature, which was based on postmortem specimens and published in 1955 prior to the advent of computed tomography (CT), is commonly used to describe the normal segmental bronchial anatomy and various abnormalities. However, several additional anomalies have been recognized since that time, and there is some confusion over the names used to describe these anomalies. Several congenital branching anomalies affecting the trachea, main bronchi, and intermediate bronchus have been reported, all of which can be recognized at chest CT but are often overlooked. These anomalies, which probably occur early in fetal life, can be either supernumerary, with defects occurring at 29-30 days gestation, or displaced, with defects occurring later. Tracheobronchial positional anomalies are often associated with other congenital abnormalities but may be isolated. They often are asymptomatic but can be responsible for pulmonary symptoms such as dyspnea, recurrent pneumonia, and hemoptysis. It is essential that these anomalies are recognized prior to lung resection to avoid complications, especially when video-assisted thoracoscopic surgery is performed. In addition, bronchoscopists should be aware of these anomalies before performing diagnostic or therapeutic bronchoscopic procedures. Awareness of a few key bronchial anatomic principles and use of a lobe-based classification scheme will facilitate recognition of tracheobronchial positional anomalies.

Fetal Brain MRI: Novel Classification and Contribution to Sonography.

PURPOSE: 1) To evaluate and classify the indications for fetal brain MRI in a tertiary referral center. 2) To assess the contribution of fetal brain MRI to fetal neurosonography. MATERIALS AND METHODS: A retrospective study in a tertiary medical center during a two-year period (2011 - 2012) included pregnant women who underwent fetal brain MRI. MRI was implemented at 32 weeks of gestation unless a severe abnormality possibly requiring earlier medical intervention was suspected. RESULTS: 633 patients were included, 40 (6.3%) underwent repeated examinations with a total of 733 fetal MRI scans. Patients were classified to three main indication cohorts: Suspected primary brain anomaly (52.9%), non-CNS disorders (32.5%) and obstetrical complications (14.6%). These cohorts were further divided into 16 separate groups with lateral ventricle abnormalities being the most common (23.7%), followed by exposure to TORCH (17.5%) and cerebral cortex abnormalities (13%). 149 (19.3%) fetal MRI scans demonstrated additional findings. Repeated examinations were commonly implemented in complicated monochorionic-biamniotic (MCBA) twin pregnancies (34.6%) and in cases of supra-tentorial cysts (19%). The average gestational age for MRI scan in the MCBA group was 26 ±â€Š5 weeks in comparison to ≥ 31st weeks in all other groups (p < 0.001). CONCLUSION: The current study describes a detailed picture of fetal brain MRI indications. Most patients were referred because of CNS anomalies. The impressive diversity of 16 separate entities emphasizes the expanding use of fetal brain MRI. Complicated MCBA pregnancies, which may have dramatic events, constitute a unique challenge due to early and repetitive MRI examinations and may serve as a role model for the contribution of fetal MRI during antenatal evaluation. The contribution of MRI to prenatal evaluation in various indications is discussed.

Defining Features of the Upper Extremity in Holt-Oram Syndrome.

PURPOSE: To investigate the distinguishing morphological characteristics of children with radial longitudinal deficiency (RLD) in Holt-Oram syndrome (HOS). METHODS: One hundred fourteen involved extremities in 62 patients with a diagnosis of HOS were identified at 3 institutions. Medical records and radiographs were evaluated. Radial longitudinal deficiency and thumb hypoplasia were classified according to the modified Bayne and Klug classification and Blauth classifications, respectively, when possible. Other unusual or distinguishing characteristics were catalogued. RESULTS: There was bilateral involvement in 84% of patients. The forearm was involved in 81% of the extremities and a shortened distal radius (Bayne and Klug type I RLD) was the most commonly identified forearm anomaly (40%). Radioulnar synostosis was present in 15% of the extremities, all in the proximal forearms with reduced radial heads. Thumb aplasia (Blauth type V hypoplastic thumb) was the most common type of classifiable thumb abnormality and occurred in 35% of involved thumbs. Twenty-seven percent of abnormal thumbs affected were not classifiable according to the Blauth classification, and 19% of involved thumbs (hypoplastic or absent) had first-web syndactyly. CONCLUSIONS: The upper extremity in HOS differs from the typical presentation of RLD. The forearm is more often involved and may demonstrate radioulnar synostosis. The thumb is frequently unclassifiable by the Blauth classification and has first-web syndactyly. The presence of radioulnar synostosis and syndactyly of the radial 2 digits in RLD should prompt the hand surgeon to obtain a cardiac evaluation and consider genetic testing for HOS. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic III.

Clinical and genetic study on 356 Brazilian patients with a distinct phenotype of cleft lip and palate without alveolar ridge involvement.

Oral clefts include cleft lip (CL), cleft lip with cleft palate (CLP) and cleft palate (CP), with wide variations in clinical presentation and degree of severity. We described a sample of individuals with CL and CP without alveolar arch involvement (CL + CP) to verify if the characteristics of this group are distinct from those with CL with or without CP (CL/P) described in literature. The sample was composed of 356 patients with CL + CP, registered at HRCA-USP, Bauru-SP-Brazil. The following characteristics were investigated: sex ratio, parental age at the time of conception, parental consanguinity, familial recurrence, laterality of the cleft and associated anomalies. A subgroup of 30 individuals with microforms of CL and CP were taken from the sample and compared with the remaining cases. Statistical differences were found between this CL + CP sample and the literature data for groups with CL/P regarding laterality, sex ratio, consanguinity, familial recurrence, and the presence of associated anomalies. The microform sample showed a statistical difference in paternal age. In most evaluated aspects, this sample presents similar characteristics to the consulted literature data for CL/P; as do the group of microform cleft cases when compared with the remaining CL + CP sample in this study. Microforms of cleft can represent a target group for investigation into the embryogenetic mechanisms of oral clefts and their phenotypic variability.

The Tessier number 3 cleft: a report of 10 cases and review of literature.

The Tessier number 3 cleft is one of the most intricate and destructive of all facial clefts, presenting surgeons with a difficult task for reconstruction. We present a series of 10 patients with this rare cleft all treated by a single surgeon over 30 years. All patients with Tessier number 3 clefts treated between 1978 and 2008 by the senior surgeon were reviewed. Demographic data and all associated clinical findings including cranial and extracranial anomalies were recorded. Methods used to reconstruct each patient were also noted. Seven males and three females were identified and age at initial treatment ranged from 12 months to 12 years. Mean follow-up was 6.3 years. Multiple craniofacial anomalies were appreciated including other rare facial clefts, hypertelorbitism, lacrimal obstruction, anophthalmia, choanal atresia, and hemifacial microsomia. Amniotic banding was the most prominent extracranial finding noted in these patients. Tessier number 3 clefts can be associated with multiple other craniofacial anomalies making reconstruction challenging. Soft tissue and bony reconstruction must be considered separately, and a variety of tools may be employed to accomplish each goal. As the presentation can be highly variable, an individualized treatment plan must be made to meet each patient's specific needs.

HEAR MAPS a classification for congenital microtia/atresia based on the evaluation of 742 patients.

OBJECTIVE: Describe anatomical and radiological findings in 742 patients evaluated for congenital aural atresia and microtia by a multidisciplinary team. Develop a new classification method to enhance multidisciplinary communication regarding patients with congenital aural atresia and microtia. METHODS: Retrospective chart review with descriptive analysis of findings arising from the evaluation of patients with congenital atresia and microtia between January 2008 and January 2012 at a multidisciplinary tertiary referral center. RESULTS: We developed a classification method based on the acronym HEAR MAPS (Hearing, Ear [microtia], Atresia grade, Remnant earlobe, Mandible development, Asymmetry of soft tissue, Paralysis of the facial nerve and Syndromes). We used this method to evaluate 742 consecutive congenital atresia and microtia patients between 2008 and January of 2012. Grade 3 microtia was the most common external ear malformation (76%). Pre-operative Jahrsdoerfer scale was 9 (19%), 8 (39%), 7 (19%), and 6 or less (22%). Twenty three percent of patients had varying degrees of hypoplasia of the mandible. Less than 10% of patients had an identified associated syndrome. CONCLUSION: Patients with congenital aural atresia and microtia often require the intervention of audiology, otology, plastic surgery, craniofacial surgery and speech and language professionals to achieve optimal functional and esthetic reconstruction. Good communication between these disciplines is essential for coordination of care. We describe our use of a new classification method that efficiently describes the physical and radiologic findings in microtia/atresia patients to improve communication amongst care providers.

Oculoauriculofrontonasal syndrome: case series revealing new bony nasal anomalies in an old syndrome.

Frontonasal Dysplasia (FND) and Oculo-auriculo-vertebral spectrum (OAVS) are two well-recognized clinical entities. With features of both FND and OAVS, the term oculoauriculofrontonasal syndrome (OAFNS) was coined in 1981. The OAFNS phenotype combines elements of abnormal morphogenesis of the frontonasal and maxillary process (derived from forebrain neural crest) with abnormal development of the first and second branchial arches (derived from hindbrain neural crest). We present a case series of 33 children with OAFNS ascertained from a comprehensive review of the literature and report an additional retrospective series of eight patients displaying features consistent with OAFNS. Notably, in a subset of our cases, we have observed abnormalities in nasal ossification and bony structures of the maxilla that have not previously described in OAFNS and are not seen in either FND or OAVS. We present the phenotype and novel naso-maxillary findings and explore potential etiologic and developmental pathways for OAFNS. We highlight the differences in phenotypic characteristics of OAFNS compared to OAVS and FND. These observations support the classification of OAFNS as a discrete syndrome. Further phenotypic refinements of OAFNS are needed to understand pathogenesis of this syndrome and the newly described nasal malformation may help identify the etiology.
