Recognizing others' emotional expressions is vital for socioemotional development; impairments in this ability occur in several psychiatric disorders. Further study is needed to map the development of this ability and to evaluate its components as potential transdiagnostic endophenotypes. Before doing so, however, research is required to substantiate the test-retest reliability of scores of the face emotion identification tasks linked to developmental psychopathology. The current study estimated test-retest reliability of scores of one such task, the facial expression labeling task (FELT) among a sample of twin children (N = 157; ages 9-14)...

The nasal septal cartilage is thought to be a key growth center that contributes to nasofacial skeletal development. Despite the developmental influence of the nasal septum however, humans often exhibit a high frequency of septal deviation suggesting discordance in the growth between the septum and surrounding nasofacial skeleton. While there are numerous etiological factors that contribute to septal deviation, the surrounding nasofacial skeleton may also act to constrain the septum, resulting in altered patterns of growth...

Ameloblastoma is a locally aggressive tumor derived from odontogenic epithelium. Although benign, its clinical behavior can often exhibit malignant characteristics. It is marked by slow and persistent growth with infiltration of adjacent tissues. Almost 70% occur in the mandible in patients older than 30 years. Recurrence of ameloblastoma from inadequate treatment is frequent. Because of its slow growth, recurrences can present decades after primary surgery. A primary ameloblastoma in an area outside the mandibular, maxillary, and infratemporal fossa regions has not been described in detail to date, with only 1 possible case mentioned in the literature...

Noonan syndrome (NS) is an autosomal dominant trait characterized by genotypic and phenotypic variability. It belongs to the Ras/MAPK pathway disorders collectively named Rasopathies or neurocardiofaciocutaneous syndromes. Phenotype is characterized by short stature, congenital heart defects, facial dysmorphisms, skeletal and ectodermal anomalies, cryptorchidism, mild to moderate developmental delay/learning disability, and tumor predisposition. Short stature and skeletal dysmorphisms are almost constant and several studies hypothesized a role for the RAS pathway in regulating bone metabolism...

We describe a case of left homolateral complete cleft lip/palate associated with a congenital left maxillary teratoma and left orbital teratoma. The patient required step-by-step reconstruction that first included resection of the 2 teratomas in consideration of cleft lip repair, cleft palate repair, and correction of the left periorbital anomalies, which were performed later. After performing all the necessary procedures, complete resection of the tumors and correction of the anomalies associated with the lip, palate, and left orbit were achieved...

Seven male Labrador retriever puppies from four different litters were identified with a brachycephalic-like face and skull, associated with low birth weight, severe growth retardation, and reduced abilities to crawl and suckle, which were not compatible with survival. Excessive doming of the cranium, brachygnathia superior and inferior, and an abnormally opened fontanelle were found in all affected puppies by computed tomography and at post-mortem examination. Pedigree analysis supported an X-linked recessive mode of inheritance...

Random skin flaps are commonly used in plastic and reconstructive surgery for patients suffering from severe or large scale wounds or in facial reconstruction. However, skin flaps are sometimes susceptible to partial or complete necrosis at the distal parts of the flaps due to insufficient blood perfusion in the defected area. In order to improve neovascularization in skin flaps, we developed an exogenous growth factor (GF) delivery platform comprised of coacervate-coated poly(lactic-co-glycolic acid) (PLGA) nanofibers...

INTRODUCTION: Autologous fat grafting is a valuable tool in the correction of facial soft tissue asymmetry and volume deficits. Pubertal growth and fluctuations in body mass present unique challenges to achieving satisfactory results after autologous fat transfer in the pediatric population. Few studies exist describing the outcomes and complications of pediatric facial fat grafting. The objective of this study is to identify the complication profile and outcomes after autologous fat grafting for the correction of facial asymmetry and volume deficits in the pediatric population...

The effects on craniofacial growth of two different soft palate repair techniques in two-stage palatoplasty were investigated. This was a retrospective, cross-sectional cohort study of 68 children with non-syndromic, complete unilateral cleft lip and palate. Thirty-four patients were treated with the modified Furlow method (F-group) and the remaining 34 with the Widmaier-Perko method (P-group). Craniofacial growth was assessed by analyzing 12 angular and 12 linear measurements on lateral cephalograms. Composite facial diagrams from the two groups were compared with those of a control non-cleft group...

Temporomandibular joint ankylosis manifests a range of clinical characteristics dependent upon the age of onset, the affected side, and the severity. When it occurs during development, mandibular growth is affected, resulting in severe retrusion or asymmetry as well as limitation of mandibular movements. Progressive asymmetric mandibular growth in unilateral ankylosis causes canting of the occlusal plane. In this case report, we present a successful temporomandibular joint reconstruction using transport distraction osteogenesis combined with camouflage orthodontic treatment for occlusal canting correction of a patient with unilateral temporomandibular joint ankylosis and severe facial asymmetry...

REVIEW
Lintas Carla, Persico Antonio Maria
Kabuki Syndrome (KS) is a rare genetic syndrome characterized by a typical facial gestalt, variable degrees of intellectual disability, organ malformations, postnatal growth retardation and skeletal abnormalities. So far, KMT2D or KDM6A mutations have been identified as the main cause of KS, accounting for 56-75% and 3-8% of cases, respectively. Patients without mutations in one of the two causative KS genes are often referred to as affected by Kabuki-like syndrome. Overall they represent approximately 30% of KS cases, pointing towards substantial genetic heterogeneity for this condition...

Early correction of developing class III malocclusions remains a complex challenge. Treatment approaches for these young patients have been directed at growth modification. Encouraging outcomes have been reported with the use of Class III functional appliances including reverse twin block (RTB) appliance. The present paper tries to provide an insight into RTB appliance used for successful interceptive management of developing class III malocclusion in two children. RTBs were fabricated with bite registered in the position of maximum possible retrusion of mandible with interincisal clearance of 2 mm and vertical clearance of 5 mm in the buccal segments...
