BACKGROUND: The number of surgical procedures to repair a cleft palate may play a role in the outcome for maxillofacial growth and speech. The aim of this systematic review was to investigate the relationship between the number of surgical procedures performed to repair the cleft palate and maxillofacial growth, speech and fistula formation in non-syndromic patients with unilateral cleft lip and palate. MATERIAL AND METHODS: An electronic search was performed in PubMed/old MEDLINE, the Cochrane Library, EMBASE, Scopus and CINAHL databases for publications between 1960 and December 2015...

Traditionally, maxillary hypoplasia in the setting of cleft lip and palate is treated via orthognathic surgery at skeletal maturity, which condemns these patients to abnormal facial proportions during adolescence. The authors sought to determine the safety profile of computer-aided design/computer-aided modeling (CAD/CAM) planned, Le Fort I distraction osteogenesis with internal distractors in select patients presenting at a young age with severe maxillary retrusion. The authors retrospectively reviewed our "early" Le Fort I distraction osteogenesis experience-patients performed for severe maxillary retrusion (≥12 mm underjet), after canine eruption but prior to skeletal maturity-at a single institution...

Tessier facial clefts are among the rarest facial clefts reported in literature and many contradicting issues have always been rising over the management and surgical approaches involved during the craniofacial cleft repair. Among the craniofacial clefts Tessier no. 4 is an extremely rare facial anomaly, and there are very few evidence which clearly describe the surgical approaches and techniques. Often these type of craniofacial clefts yield very poor surgical results, and they require multidisciplinary sequential corrective surgeries...

Hyperphosphatasia with mental retardation syndrome (HPMRS) is caused by recessive mutations in genes involved in the glycosylphosphatidylinsitol pathway, including PGAP3. Herein, we describe 10 patients from 8 Egyptian families presenting with developmental delay, severe intellectual disability, distinct facial dysmorphism and increased alkaline phosphatase. Eight patients had cleft palate, four had postnatal microcephaly and five had seizures. Neuroimaging findings showed thin corpus callosum in 9 patients, mild ventriculomegaly in 3 patients and variable degrees of cerebellar vermis hypoplasia in 4 patients, a finding not previously reported in patients with HPMRS...

BACKGROUND: Alveolar cleft reconstruction using iliac crest bone graft(ICBG) is considered standard of care for children with complete cleft lip and palate at the time of mixed dentition. Harvesting bone may result in donor site morbidity, additional operating time and length of hospitalization. Recombinant human bone morphogenetic protein(rhBMP)-2 with a demineralized bone matrix(DBM) was used as an alternative bone source for alveolar cleft reconstruction. We investigate the outcomes of rhBMP-2/DBM versus ICBG for alveolar cleft reconstruction by reviewing postoperative surgical complications and cleft closure...

The rapid increase in gene-centric biological knowledge coupled with analytic approaches for genomewide data integration provides an opportunity to develop systems-level understanding of facial development. Experimental analyses have demonstrated the importance of signaling between the surface ectoderm and the underlying mesenchyme in coordinating facial patterning. However, current transcriptome data from the developing vertebrate face is dominated by the mesenchymal component, and the contributions of the ectoderm are not easily identified...

BACKGROUND: Facial cosmetic results are one of the most concerning issues for the parents who get their children operated for cleft lip. Moreover, the postoperative care of the surgical site, the discomfort associated with the suture removal, and additional visit for suture removal are other reasons which encourages one to use any new technologies that may replace the need for suture placement. In this study, we used octyl-2-cyanoacrylate, a tissue adhesive which offers a viable alternative to traditional techniques without compromising optimal wound closure...

BACKGROUND: Complex surgery for appearance change is controversial. Correction of orbital hypertelorism risks diplopia and loss of stereopsis for aesthetic gain. The risk-to-benefit ratio remains ill-defined. The aim of this study was to define specific ocular morbidity following orbital translocation. METHODS: The authors compared stable preoperative and postoperative orthoptic indices (i.e., angle of strabismus, ocular motility, and acuity) for 23 consecutive patients who underwent orbital translocation between 2000 and 2015 and noted the requirement for corrective surgery...

Primary cilia are nearly ubiquitous, cellular projections that function to transduce molecular signals during development. Loss of functional primary cilia has a particularly profound effect on the developing craniofacial complex, causing several anomalies including craniosynostosis, micrognathia, midfacial dysplasia, cleft lip/palate and oral/dental defects. Development of the craniofacial complex is an intricate process that requires interactions between several different tissues including neural crest cells, neuroectoderm and surface ectoderm...

Knowledge of congenital malformations and their causes in horses is generally sparse. Such conditions require more scientific attention to improve their diagnostics and inform prevention strategies. Here, a unique syndrome of bilateral oblique facial clefts (meloschisis), rudimentary eyes and hydrocephalus is reported in an equine foetus spontaneously aborted at gestation day 224. The cause of abortion was considered to be intrauterine death caused by umbilical cord torsions and subsequent compromised blood flow, but the aetiology of the malformation could not be determined...

Craniofacial deformities with multifactorial etiologies, such as cleft palate and facial dysmorphism, represent some of the most frequent congenital birth defects seen in humans. Their pathogeneses are often related to cranial neural crest (CNC) cells. During CNC cell migration, changes in cell shape and formation, as well as maintenance of subcellular structures, such as filopodia and lamellipodia, are dependent on the complex functions of Rho family small GTPases, which are regulators of actin cytoskeletal organization...

Hemifacial microsomia (HFM) is a rare, multisystemic congenital disease with estimated frequency of 1/26370 births in Europe. Most cases are sporadic and caused by unilateral abnormal morphogenesis of the first and second pharyngeal arches. The aim of this study is to define the types and frequency of maxillofacial and systemic malformations in HFM patients. This is a case series study of patients with HFM evaluated at a single institution. Data were acquired through history, physical examination, photographs, diagnostic radiology, and laboratory and analyzed by the FileMakerPro database on 95 patients (54F; 41M) of which 89 met the inclusion criteria...

3MC syndrome is an autosomal recessive heterogeneous disorder with features linked to developmental abnormalities. The main features include facial dysmorphism, craniosynostosis and cleft lip/palate; skeletal structures derived from cranial neural crest cells (cNCC). We previously reported that lectin complement pathway genes COLEC11 and MASP1/3 are mutated in 3MC syndrome patients. Here we define a new gene, COLEC10, also mutated in 3MC families and present novel mutations in COLEC11 and MASP1/3 genes in a further five families...

CONTEXT: Facial cosmetic result is one of the most concerning issues for the parents who get their children operated for cleft lip. Moreover, the discomfort associated with the suture removal encourages one to use any new technology that may replace the need for suture placement. The type of suture material used in surgery has been a long-standing debate among surgeons. In this study, we compared rapidly absorbable suture material (Vicryl Rapide™) with nonabsorbable suture material (nylon)...

BACKGROUND: Cleft lip and palate (CLP) are the most common craniofacial birth impairment and one of the most common congenital impairments in humans. Anecdotal evidence suggests that stigmatization, discrimination, and sociocultural inequalities are common "phenomenon" experienced by families of children with CLP in Nigeria. This study aimed to explore the stigmatization, discrimination, and sociocultural inequalities experiences of families with children born with CLP. MATERIALS AND METHODS: The study was carried out at the surgical outpatient cleft clinic of the Lagos University Teaching Hospital, Lagos, Nigeria...

Palate development is an important morphogenetic event in facial development, including the fusion of the lateral and medial nasal portions of the frontonasal process and maxilla. Derailments of any of these events may result in cleft palate, the most frequent congenital craniofacial abnormality. Recent research has shown that the microanatomy of the miniature pig oral maxillofacial region is quite similar to that of humans, and the use of miniature pigs as a large animal model for dental and orofacial research is increasing...

OBJECTIVE: Restoration of the philtral region following traumatic, cleft, and tumor surgeries is often difficult due to influence of this feature to whole facial beauty. The aim of this study is to investigate the types and measurements of the philtrum and its relationship with the upper lip using a software. METHODS: Standard personal photographs of the philtral region were obtained from 200 young adults participated in this study. Linear analyses (the lengths of philtral column and dimple; the philtral width) and angular analyses (apex and central angles of Cupid's bow) were measured as reference points...

Lateral or transverse facial clefts are the most frequent of the atypical facial clefts, classified by Tessier as no. 7 clefts. Most of the cases are diagnosed at birth, while few cases are diagnosed prenatally. We report a case of prenatal ultrasound detection and three-dimensional characterisation of a lateral facial cleft at 21 weeks of gestation, which was terminated at 22 weeks. It was a transverse cleft, running through the left cheek towards the ear, along with micrognathia and mild polyhydramnios. We also present a review on classification, anatomical features and prenatal diagnosis of Tessier no...

Defects in the fusion of facial buds can result from an anomaly in tissue development or apoptosis, or both. Our working hypothesis was that anomalies in the development of tissues could be caused by a genetic angiogenic defect. Our main objective was to design a reproducible experimental model to study the expression of angiogenic genes in the borders of cleft lips with or without cleft palate. We therefore prospectively studied seven non-syndromic patients, three with a cleft lip (2 right, 1 left), and four with a cleft lip and palate (1 bilateral, 2 right, 1 left), with no CGH (comparative genomic hybridisation) array, who had primary operations to repair their clefts...

BACKGROUND AND PURPOSE: In 1989, the Cleft Palate-Craniofacial Journal published the first randomized prospective cleft surgery study, comparing the Kriens intravelar veloplasty (IVV) with a non-IVV 2-flap repair. Results in that and follow-up publications yielded no difference between the 2 groups for need for secondary velopharyngeal management. The subjects have now reached adulthood. This study was designed to ask: Is there any difference between the groups in the outcomes that multidisciplinary team care addresses: speech intelligibility, facial growth, breathing while awake and asleep, attainment of education, and long-term socioeconomic status? METHODS: Enrollees from the original published study were invited to participate in a survey...
