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...

INTRODUCTION: Computer-assisted preoperative simulation surgery is employed to plan and interact with the 3D images during the orthognathic procedure. It is useful for positioning and fixation of maxilla by a plate. We report a case of maxillary retrusion by a bilateral cleft lip and palate, in which a 2-stage orthognathic procedure (maxillary advancement by distraction technique and mandibular setback surgery) was performed following a computer-assisted preoperative simulation planning to achieve the positioning and fixation of the plate...

Defects in mid-facial development, including cleft lip/palate, account for a large number of human birth defects annually. In many cases, aberrant gene expression results in either a reduction in the number of neural crest cells (NCCs) that reach the frontonasal region and form much of the facial skeleton or subsequent failure of NCC patterning and differentiation into bone and cartilage. While loss of gene expression is often associated with developmental defects, aberrant upregulation of expression can also be detrimental...

Cleft lip and palate is one of the most common congenital anomalies. For many years, surgeons have been attempting to reduce the severity of the deformity before the surgical repair to achieve a better outcome. The nasoalveolar molding technique uses acrylic nasal stents attached to the vestibular shield of an oral molding plate to mold the nasal alar cartilages into a more normal form and position during the presurgical period. Proponents of nasoalveolar molding claim several benefits, including improved aesthetic outcome, reduced overall costs, and a psychosocial benefit to the family...

Birth defects are one of the most common adverse birth outcomes, which create a heavy economic burden to the country, society and family. And they are also one of the biggest problems facing public health today. Polycyclic aromatic hydrocarbons (PAHs) are a group of toxic pollutants existing in the environment widely, resulting from incomplete organic matter combustion, and can be taken into the body through various ways including the digestive tract, respiratory tract and so on. Recent researches suggest that the exposure of PAHs may be associated with various birth defects, while the special mechanism isn't very clear...

OBJECTIVE:   Tinagl1 has a weak genetic association with craniosynostosis, but its functions in cartilage and bone development are unknown. Knockdown of Tinagl1 in zebrafish embryos allowed an initial characterization of its potential effects on craniofacial cartilage development and a test of whether these effects could involve Wnt signaling. RESULTS:   Tinagl1 knockdown resulted in dose-dependent reductions and defects in ventral pharyngeal arch cartilages as well as the ethmoid plate, a zebrafish correlate to the palate...

Bilateral cleft lip/cleft palate is associated with nasal deformities typified by a short columella. The presurgical nasoalveolar molding (NAM) therapy approach includes reduction of the size of the intraoral alveolar cleft as well as positioning of the surrounding deformed soft tissues and cartilages. In a bilateral cleft patient, NAM, along with columellar elongation, eliminates the need for columellar lengthening surgery. Thus the frequent surgical intervention to achieve the desired esthetic results can be avoided...

In this video, we present a single piece Le Fort I osteotomy with bone graft in a patient with a unilateral cleft lip and palate. Maxillary osteotomies in the cleft patient can be challenging because of the presence of scar, palatal or alveolar fistulae, compromised teeth, and vascularization of the segments. The video demonstrates our current approach and technique. The authors particularly want to highlight aspects of the approach, such as the incision, exposure, osteotomies, mobilization, splints, and plating...

PURPOSE: Computer-assisted design and computer-aided manufacturing (CAD/CAM) technology in nasoalveolar molding (NAM) should save time and manpower and reduce family input in cases of cleft lip and palate. MATERIAL AND METHODS: Intraoral casts from 12 infants with complete unilateral cleft lip and palate were taken immediately after birth (T1) and after (T2) NAM treatment, digitalized, and transformed into STL data. The infants were randomized into Group 1 (n = 6) receiving conventional NAM treatment or Group 2 receiving CAD/CAM NAM (n = 6)...

Mandibulofacial dysostosis (MFD) is a human developmental disorder characterized by defects of the facial bones. It is the second most frequent craniofacial malformation after cleft lip and palate. Nager syndrome combines many features of MFD with a variety of limb defects. Mutations in SF3B4 (splicing factor 3b, subunit 4) gene, which encodes a component of the pre-mRNA spliceosomal complex, were recently identified as a cause of Nager syndrome, accounting for 60% of affected individuals. Nothing is known about the cellular pathogenesis underlying Nager type MFD...

INTRODUCTION: Traditional Figueroa nasoalveolar molding (NAM) requires weekly or biweekly adjustments to remove acrylic from the palatal plate to narrow the alveolar gap. These frequent adjustments create a burden for patients living far from a hospital. To minimize this burden, we developed a modified NAM technique using simplified lip taping and a passive palatal plate. Herein we present our clinical experience and outcomes using the traditional and modified methods. MATERIAL AND METHODS: In this blinded, retrospective study of 66 patients with complete unilateral cleft lip and palate, 33 received the traditional NAM and 33 received the modified NAM...

To compare the three-dimensional changes occurring in the maxillary arch during the use of modified pre-surgical nasoalveolar moulding (PNAM) and Hotz's plate. A clinical trial including 32 children with unilateral cleft lip and palate (UCLP), 16 treated with Hotz's plate and 16 with PNAM, was performed. Impressions of the maxillary arches were taken: A. prior to pre-surgical orthopaedics, B. before cheiloplasty and C. after cheiloplasty. Models were digitised using a stereophotogrammetric instrument, and geodesic distances were calculated: anterior, canine and posterior widths of the arch, and lengths and cleft depths of the larger and shorter segments...

BACKGROUND: Residual deformity of the nose, not lip, continues to be the greater challenge in UCCLP rehabilitation. Platform distortions often re-emerge following primary reconstruction revealing the stereotypical cleft-nose. Nasal alveolar molding reduces nose asymmetry. However, this study applies directional mechanics to the underlying platform distortions and soft tissue nose, introducing a novel device addressing the distorted septo-premaxillary junction. METHODS: Retrospective assessment of 47 UCCLP patients by 2-dimensional photographic analysis with 24 subjects treated by dento-maxillary advancement (DMA) and nasal septum button-head pin (NSBP), 17 having nasal molding (NM), compared to 23 subjects without nose treatment, 16 with DMA and 7 with passive plates...
