Abstract
OBJECTIVE Cleft lip and palate is the main craniofacial malformation in France. Many surgical techniques had been described to restore cleft palate. In this study, we evaluate phonation in a homogeneous series of patient with isolated unilateral non-syndromic cleft lip and palate before (and after) alveolar cleft closure, operated according to our surgical protocol. METHODS We included retrospectively 71 patients with isolated non-syndromic unilateral cleft lip and palate (UCLP), operated in our department from 2009 to 2013. All patients underwent the same surgical protocol: modified Millard cheilorhinoplasty (from 5 to 9-month-old); direct hard palatal closure (from 12 to 20-month-old); alveolar cleft closure with cancellous iliac bone graft (from 4 to 6-year-old). The phonation and clinical statute were evaluated before and after alveolar cleft closure. Fistula rate and speech evaluation were recorded. RESULTS The rate of oronasal fistula was 12.7%. About phonation, 76% and 86% of patients were competent or borderline competent respectively before and after gingivoperiostoplasty. CONCLUSION This surgical protocol provided speech results in patients with isolated unilateral non-syndromic cleft lip and palate. The gingivoperiostoplasty improved the speech intelligibility.

Abstract
AIM The aim of the study was to investigate hyoid bone anomalies in patients with Pierre Robin sequence (PRS) compared to the control group, using computed tomography (CT) examination and three-dimensional reconstruction of the hyoid bone and mandible. METHODS A retrospective study was performed of patients between birth and 12 months old with isolated PRS (i-PRS) and syndromic PRS (ni-PRS), who had undergone CT examination, and whose results were compared to the control group of the same age. DICOM data was processed to highlight bone tissue. The mandible and hyoid bones were the main targets of the three-dimensional reconstruction. The study outcomes were the analysis of hyoid bone ossification, volume, and position (distance between hyoid and mandibular symphysis). Univariate and multivariate statistical analyses were performed with α=0.05 as level of significance. RESULTS The study sample included 29 i-PRS and 21 ni-PRS patients, while 43 infants in the control group. Hyoid ossification was present in 26/50 (52%) PRS patients (14 i-PRS; 12 ni-PRS) but in 31/43 controls (72%). Statistical analysis showed that absence of hyoid ossification was significantly associated with the diagnosis of PRS (P<0.05). Only ni-PRS patients showed a significant reduction of the distance between hyoid and mandible compared to the control group (P<0.001). Hyoid volume was significantly lower only in the ni-PRS group than in controls (P<0.001). CONCLUSION I-PRS and ni-PRS patients differ both etiologically and clinically. Ni-PRS patients confirmed their worst clinical condition than i-PRS with severe anomalies of hyoid development, helping for their ontogeny classification.

Abstract
Residual nasal deformity in patients with cleft palate remains the main demand of these patients. Performing primary nasal surgery has significantly improved the results. However, it is still often necessary to improve the nasal morphology. Respect of tissues during primary surgery is essential and allows easier secondary corrections. Anatomical reconstruction greatly facilitates the treatment of secondary deformities. Do not hesitate in case of major labionasales sequelae, to make revision, according to the rules of primary surgery, of the entire lip and nose.

Abstract
BACKGROUND AND PURPOSE Differentiating major subtypes of cervicofacial vascular lesions is crucial for appropriate management. The aim of our study was to evaluate the performance of an MR imaging arterial spin-labeling perfusion sequence in discriminating pediatric cervicofacial soft-tissue vascular anomalies. MATERIALS AND METHODS We conducted a retrospective analysis of data from a prospectively maintained registry including pediatric patients at a tertiary pediatric center between January 2012 and January 2014. We included pediatric patients with a final diagnosis of soft-tissue vascular anomalies and an MR imaging, including an arterial spin-labeling sequence at presentation. We performed an analysis of lesion perfusion, blinded to clinical data, by using concurrent spiral 3D pseudocontinuous arterial spin-labeling (1.5T magnet; spiral matrix, 512 × 8 mm; postlabeling delay, 1025 ms). Lesional flow was recorded with calibrated intralesional ROIs. Perfusion characteristics were compared among lesion subtypes with the Mood Median test. RESULTS Among 840 patients screened, 46 matched the inclusion criteria and were included (median age, 1.45 years; interquartile range, 0.4-5.1 years; 27 females). Hemangiomas, including infantile hemangiomas (n = 18 patients) and noninvoluting (n = 2) and rapidly involuting (n = 1) congenital types, demonstrated marked hyperperfusion (median flow, 436 mL/min/100 g; interquartile range, 212.5-603 mL/min/100 g), significantly higher than that of lymphatic malformations (median, 22.5 mL/min/100 g; interquartile range, 16-60 mL/min/100 g; P < .001) or venous malformations (median, 25 mL/min/100 g; interquartile range, 15-66.5 mL/min/100 g; P = .003). CONCLUSIONS MR imaging arterial spin-labeling is a valuable tool for the assessment of soft-tissue vascular anomaly hemodynamics and for the classification of major lesion subtypes.

Abstract
Facial traumas are common in children but often unconsidered. Facial injury is responsible of impressive bleeding because of the rich vascularization of the face; this bleeding is often underestimated because of the immediate arterial vasoconstriction that is very strong for children. The blood volume is 80ml/kg for a newborn, with a total of 250ml, reaching 70ml/kg at one year of age. The evaluation must be rigorously performed due to the risk of a sudden decompensation. Regarding the wounds, the primary repair must be performed directly neat or optimal in case of damaged tissues. The rule is to keep maximum of the integrity and to limit debridement. Careful repair often requires general anesthesia, especially in young children, to facilitate a perfect joining of the edges and of the mucocutaneous lines. Losses of substance should be treated by directed cicatrization. Flaps are never performed in children as a first intention for reasons developed below. Given the elasticity of the facial skeleton, fractures require a brutal shock to occur, but the clinical signs can be misleading. For instance, too specific and sometimes ignored, fractures can show weakly symptomatic signs : the fractures of the condylar and the orbital floor, with their respective complication that are temporomandibular bone ankylosis and definitive diplopia. Possible children abuse should be suspected in case of different age lesions and discrepancies between the told story and types of injuries. Once the vital urgency is eliminated, the orbital emergency should be first considered in facial traumas within the ophthalmology specialty because wounds and contusions of the globe are often under-evaluated and threaten the vision. The second emergency is the orbital floor fracture in its 'trapdoor' type, specific to the child. Combined with a motionless eye and uncontrollable vomiting, this is the second true urgency because it involves the prognosis of the oculomotricity and requires emergency surgery. Finally, dental trauma should not be overlooked because of their functional and aesthetic consequences. Primary cicatrization is usually rapid but scars remain inflammatory during a long time. The risk of hypertrophy exists in case of contusions and lacerations associated with wounds but also during puberty and in some locations. Age interfere with the result because growth will either improve or worsen the initial result, depending on the location and mechanism. The secondary specialized and prolonged managing and monitoring is capital on the functional, aesthetic and psychological points of view.

Abstract
The literature is rich in case reports of intraosseous haemangioma, although most of these are actually cases of venous or capillary malformations. To illustrate this confusion in terminology, we present three cases of slow-flow vascular malformations misnamed as intraosseous haemangioma. A retrospective study of children diagnosed with intraosseous haemangioma was conducted. Clinical and radiological data were evaluated. Histopathological examinations and immunohistochemical studies were redone by three independent pathologists to classify the lesions according to the International Society for the Study of Vascular Anomalies (ISSVA) and World Health Organization (WHO) classifications. Three children who had presented with jaw haemangiomas were identified. Computed tomography scan patterns were not specific. All tumours were GLUT-1-negative and D2-40-negative. The lesions were classified as central haemangiomas according to the WHO, and as slow-flow malformations according to the ISSVA. The classification of vascular anomalies is based on clinical, radiological, and histological differences between vascular tumours and malformations. Based on this classification, the evolution of the lesion can be predicted and adequate treatment applied. The binary ISSVA classification is widely accepted and should be applied for all vascular lesions.

Abstract
INTRODUCTION A reduction glossectomy may be complicated by tongue and mouth floor edema and extend the recovery time for a normal tongue function. We performed reduction glossectomy using Ultracision(®), an ultrasonic vibrating device, so as to limit these complications. TECHNICAL NOTE We performed a keyhole glossoplasty under general anesthesia. The initial tongue incision was performed with a cold scalpel, then the glossectomy was continued with Ultracision(®) only. We also used CURVED SHEARS(®). We evaluated our preliminary results with 3 patients presenting with Wiedemann-Beckwith syndrome. CONCLUSION Ultracision(®) is a useful tool for intra-oral surgery, and should soon be more frequently used. It is an alternative to electrocautery for this type of surgery.

Abstract
OBJECTIVES To evaluate the management of prenatally diagnosed cleft lip with or without cleft palate and the immediate postnatal outcome. MATERIAL AND METHODS Retrospective study of all cases of cleft lip with or without cleft palate referred to our fetal medicine unit, between January 2005 and January 2011. The anatomical type of cleft, associated malformations, and the postnatal outcome were reviewed. RESULTS Forty-three cases of fetal cleft lip with or without cleft palate were reviewed. The mean gestational age at diagnosis was 24 weeks ± 4. The postnatal distribution of clefts was: 30 cleft lip and palate (70%) and 13 cleft lip (30%). The prenatal diagnosis of the cleft type was exact in 27 cases (62.8%). Nine cases had associated anomalies (21%), detected prenatally in three cases (37.5%). There was no karyotypical abnormality. Six pregnancies were terminated (14%). The immediate postnatal outcome was comparable with unselected newborns. CONCLUSION The prenatal diagnosis of cleft lip with or without cleft palate is correct, with two thirds of exact diagnoses. Large clefts palate are the best detected. Associated malformations cannot always be diagnosed by prenatal ultrasound, but have to be searched for because they modify the fetal outcome.

Abstract
OBJECTIVE Prenatal Binder profile is a well known clinical phenotype, defined by a flat profile without nasal eminence, contrasting with nasal bones of normal length. Binder profile results of a hypoplasia of the nasal pyramid (sometimes referred to as maxillonasal dysplasia). We report 8 fetuses prenatally diagnosed as Binder phenotype, and discuss their postnatal diagnoses. METHODS Ultrasonographic detailed measurements in 2D and 3D were done on the 8 fetuses with Binder profile, and were compared with postnatal phenotype. RESULTS All fetuses have an association of verticalized nasal bones, abnormal convexity of the maxilla, and some degree of chondrodysplasia punctata. The final diagnoses included fetal warfarin syndrome (one patient), infantile sialic acid storage (one patient), probable Keutel syndrome (one patient), and five unclassifiable types of chondrodysplasia punctata. CONCLUSION This series demonstrates the heterogeneity of prenatally diagnosed Binder phenotype, and the presence of chondrodysplasia punctata in all cases. An anomaly of vitamin K metabolism, possibly due to environmental factors, is suspected in these mild chondrodysplasia punctata. We recommend considering early prophylactic vitamin K supplementation in every suspected acquired vitamin K deficiency including incoercible vomiting of the pregnancy.

Abstract
We report two cases of rapidly involuting congenital hemangioma (RICH) of the skull diagnosed in the third trimester of gestation, and also present a brief review of the literature. In both of our cases ultrasound examination showed a soft tissue vascular mass of the skull with a specific sonographic finding: a thin hyperechogenic line over the lesion and continuous with the calvaria, suggesting a subperiosteal origin and possibly accounting for a mass effect on the underlying skull. This was slight in one case and marked in the other (and associated with involvement of the calvaria). On prenatal T2-weighted magnetic resonance imaging, the signal of each of the lesions was less marked than the hypersignal encountered in the postnatal period. Postnatal clinical and radiological follow-up over the first few months after delivery confirmed the diagnosis of RICH in each case by demonstrating a significant decrease in the size of the tumor and regression of the vascular component, with complete involution of the lesion within a year.

Abstract
Velopharyngeal insufficiency remains a sequel of labial-alveolar-velopalatine clefts. It may occur despite a good quality primary repair. A surgical management must be considered as soon as speech therapy is no longer efficient or before any irreversible compensatory speech pattern appears. Thus, surgery should be decided on after consultation between the surgeon and the speech pathologist or speech therapist, when considering that speech therapy has failed. Several surgical techniques are discussed: intravelar veloplasty, Furlow double-opposing Z-plasty, pharyngoplasty using an inferior or superior pedicle flap. Superior pedicle flap surgery is currently the most commonly used technique. For the past twenty years we have used this technique as described by Petit and modified by Malek, because of the excellent speech results. The drawbacks are known and can be contained by a preventive management.

Abstract
INTRODUCTION Since 1996, vascular anomalies are classified either as tumors or malformations. Infantile hemangioma is the most common vascular tumor. It is an endothelial cellular proliferation, stimulated after birth (10th day) which then slow involves. Congenital hemangioma is a different kind of hemangioma develops prenatally appearing fully grown at birth. Rapidly involuting congenital hemangioma (RICH) generally involutes spontaneously while non involuting congenital hemangioma (NICH) usually requires a surgical procedure. The clinical and radiological aspects of these two tumors differ significantly at birth. Most congenital hemangiomas detected at antenatal ultrasonography, due to their cephalic localization and their size (up to 10 cm) are RICH. MATERIAL AND METHODS We report on five vascular tumors detected in utero during the second and third trimesters, and after birth. RESULTS There were three boys and two girls. The average size of the RICH was 5 cm (1.8-10 cm). Four were cephalic and one on a lower limb. A doppler examination was available in three patients, and showed fast-flow in two. Prenatal magnetic resonance imaging was available in three patients. DISCUSSION The diagnosis of RICH can be suspected on the antenatal ultrasonography. Fast-flow on the doppler examination confirms the diagnosis. It is advisable to repeat the ultrasonography every two to four weeks to reevaluate the possibility of delivery and the fetal cardiac status. In the event of a prenatal vascular tumor the differential diagnosis also includes other congenital tumors. Magnetic resonance imaging would be indicated if there is any doubt about malignancy. Regular follow-up is necessary during the first months to confirm the diagnosis. RICH regress rapidly while the size of malignant tumors increases. A biopsy is necessary to obtain histopatholgical proof.

Abstract
A number of infantile tumours, far less frequent than infantile haemangiomas, were long assimilated to them. Today they are clearly individualised, based on distinctive clinical and pathologic features, and this difference has been supported by the discovery of new immunophenotypic markers such as GLUT1. GLUT1 stains 100% of infantile haemangiomas and none of the other infantile vascular tumours. Congenital haemangiomas represent a group of vascular tumours still under evaluation as they have slightly heterogeneous presentation. Their prognosis is better appraised and their therapeutic management has improved. They are all fully grown in utero and they do not experience postnatal proliferation like haemangiomas do. Some of them (RICH--Rapidly Involuting Congenital Haemangioma) undergo spontaneous involution during the first year. Others (NICH--Non Involuting Congenital Haemangioma) persist lifelong. Tufted angioma and kaposiform haemangioendothelioma are histopathologically well characterized; in addition they are now considered as part of a same spectrum of vascular tumours, with the contribution of lymphatic endothelial cells in their proliferation. Both are clearly the tumours able to create platelet trapping, thrombocytopenia and the life-threatening Kasabach-Merritt syndrome. However they may occur as isolated tumours, without thrombocytopenia but with cosmetic, and sometimes function-impairing, consequences.

Traitement par vincristine des hémangiomes graves du nourrisson. Arch Pediatr 2004; 11:99-107.

Abstract
AIM To evaluate the efficacy of vincristine treatment for function- and life-threatening hemangiomas. PATIENTS AND METHOD Nine infants, eight girls and one boy, received vincristine treatment (VCR) for endangering hemangiomas. In six cases, the hemangiomas involved head and neck in a segmental unilateral or bilateral distribution (3/6 also had laryngeal and 2/6 tracheal location causing respiratory distress, 5/6 had eyelid and orbital involvement); one infant had disseminated neonatal hemangiomatosis (skin, liver, kidney); two infants had liver hemangiomas with cardiac failure. VCR was prescribed after failure of high-dosage corticosteroid treatment in six, and of both corticosteroids and interferon alpha 2b (5 months) in one; two infants received VCR as first line treatment. RESULTS A dosage of 1 mg/m(2) IV injection was delivered, with weekly injections first, and then tapering, increasing the interval between injections, depending on the clinical response. The nine infants received from 5 to 25 injections (average: 16), for a length of treatment of 1.5-8 months (average: 5.5 months). In seven patients a clear clinical response was observed at the end of the first month of treatment, while a slow protracted response was noted in two. Transient mild side effects were present in four patients. DISCUSSION Corticosteroid treatment, although a worldwide recognized treatment of problematic hemangiomas, cannot always control the growth of alarming hemangiomas. Interferon alpha 2a and 2b have proven a 90% effectiveness: treatment for cortico-resistant, function- and life-threatening, hemangiomas.

Abstract
We report a family showing autosomal-dominant segregation of upper- and lower-eyelid distichiasis (double row of eyelashes) in seven affected relatives over three generations, in addition to below-knee lymphedema of pubertal onset (lymphoedema proecox) in three. Two children had cleft palate in addition to distichiasis, but without the previously reported association with the Pierre-Robin sequence. Other ophthalmologic anomalies included divergent strabismus and early-onset myopia. This family was found to be completely linked to markers mapped to 16q24.3 and thereby proposed to be allelic to the distichiasis-lymphedema syndrome (DL, MIM 153400), although pterygium colli, congenital heart disease, or facial dysmorphism were not features found here. As FOXC2/FKLH14 mutations were found to underlie DL and diverse hereditary lymphedema conditions, this gene was examined by sequence analysis. An out-of-frame deletion (914-921del) was identified and found to segregate with the disease, further highlighting the phenotypic heterogeneity of lymphedema conditions linked to FOXC2 truncating mutations. Whether such heterogeneity is related to genotype-phenotype correlation, a hypothesis not primarily supported by the apparent loss-of-function mechanism of the mutations, or governed by modifying genes, remains to be determined.

Abstract
After defining vascular malformations and tumors, the authors approach specific problems of these lesions involving the lips. Careful planning and assessment are necessary throughout the clinical course and evolution. Therapeutic management concern the vascular anomaly but the functional, cosmetic and psychological repercussions as well. The rules of surgical treatment are discussed in this labial location. Capillary malformations can be treated by pulsed dye laser for the skin involvement, but sometimes by reconstructive surgery in case of soft tissue and bony overgrowth. Venous malformations require percutaneous sclerotherapy, partial or total removal surgery, reconstructive surgery, with or without previous embolization, according to the size and functional repercussions. Lymphatic malformations involving the lip are based upon conservative and observing treatment or surgery according to impairment and psychological impact. There is a strong tendency for these lymphatic microcystic malformations to invade and to recur after surgery. The new lasers (diode, Nd Yag) have to be assessed in this area. Arterio-venous malformations are the most severe anomaly. When the lesion is cosmetically and functionally acceptable, the authors propose conservative management waiting for therapeutic progress expected from genetics research. Otherwise management require embolization and complete surgical treatment with lip reconstruction. The first-line treatment of hemangiomas is medical and pharmacological (local medical care, corticosteroids, interferon, vincristine) but surgery may be indicated in three situations. In urgent cases with severe complications surgery is performed after failure of medical management. Early surgery is recommended to prevent functional or cosmetic disturbance or serious psychological distress. Ultrasound dissection (Dissectron) an significantly contribute to the surgical outcome. Late surgery retains its classical cosmetic and functional indications and techniques to treat the residual after-effects. Three key-words dominate the rules of therapeutic management of all types of vascular anomalies: multidisciplinary approach, experience and carefulness.

Abstract
Melanotic neuroectodermal tumour (MNET) of infancy is a rare benign but locally aggressive tumour. We describe our surgical treatment of MNET of the orbital region. There was osteogenic relapse involving the bone of the orbit, 20 days after macroscopically complete excision of the primary tumour when the patient was 12 weeks old. This is only the second report of osteogenic relapse in MNET. The relapse was treated by excision of the involved orbital floor, preserving the orbital periosteum. The tumour has not recurred in 23 months of follow-up. Residual tumour islets may regress spontaneously after incomplete excision of MNET, but the relapse rate is between 15% and 45%. In our opinion, excising a safety margin of a few mm of apparently healthy bone reduces the risk of relapse. In contrast, the orbital contents should be preserved if they are macroscopically normal. Follow-up consisted of frequent physical examinations and CT scans.

Abstract
BACKGROUND The natural course of immature hemangiomas in infants is well-known. A rapid phase of growth from 6 to 8 months is followed by a period of stability then regression. Since approximately 70% of these immature hemangiomas resolve spontaneously, abstention is generally the rule. The volume or localization of certain lesions may nevertheless have a serious functional or morphological impact. MATERIAL AND METHODS This retrospective study included 81 children who underwent surgery between October 1994 and March 2000. The children were aged 2 to 38 months at the time of surgery. Orbital localizations predominated (33 children). The indication for surgery was based on two criteria: risk of a functional impairment or risk of morphological sequela. All children with orbital hemangiomas with a functional risk of amblyopia were initially treated with corticosteroids. Surgery was performed in case of failure. The CAVITRON was used for 77 children and DISSECTRON for 4. These two ultrasound devices allowed easy dissection with little hemorrhage. RESULTS There were no peroperative hemorrhagic complications. Few postoperative complications were observed. After resection of the orbital hemangiomas there was little functional impact and the postoperative ophthalmologic examinations were normal within several weeks. Mean follow-up was 12 months after surgery. Use of an ultrasound dissector allowed early and safe treatment of immature hemangiomas. DISCUSSION Certain voluminous or poorly localized hemangiomas, particularly on the face, can have a serious function, morphological or psychological impact. Medical treatment is not always active and surgical resection may be required before the development of definitive sequelae. Ultrasound dissection, not previously used in this indication, can contribute significantly to the surgical outcome as demonstrated in these children operated on early. This technique is safe and shortens operative time. In light of these results, we believe early resection of immature hemangiomas should be reevaluated. It should not be considered as a last resort but rather as a complementary treatment.

Abstract
Cleft lip with or without cleft palate (CL/P) is one of the most common congenital malformations in humans occurring with a birth prevalence of approximately 1:1,000. CL/P may be part of a defined syndrome, sequence or association, although most individual or familial cases present as an isolated (nonsyndromic) malformation (NSCL/P). Inheritance is generally regarded as multigenic although, in some families, NSCL/P seemingly segregates as a monogenic trait. On the other hand, van der Woude syndrome (vWS) is a rare autosomal dominant with cardinal features of lower-lip pits (LLP) and CL/P or cleft palate (alone). Since none of these traits is present in all mutation carriers, some individual or familial vWS cases, especially those lacking LLP, are indiscernible from NSCL/P, raising the question whether allelic variation at the vWS locus could underlie NSCL/P. This question was addressed using parametric linkage (LOD score) analysis in 21 multiplex NSCL/P families based on a tightly linked microsatellite marker (D1S3753), and nonparametric analysis using the transmission/disequilibrium test (GTDT) in 106 NSCL/P triads and selecting markers D1S205, D1S491, and D1S3753. No evidence for linkage of NSCL/P to vWS was found on the 21 families using the LOD score approach. In contrast, TDT yielded a significant P value of 0.04 for D1S205, supporting involvement of vWS in NSCL/P in a complex, modifying/polygenic manner rather than as a monogenic/major disease locus.

Abstract
Otomandibular dysplasia are characterised by a combination of anomalies of the ear and the mandible. From the surgical point of vue, facial dysostosis is prominent and focus the attention. For the geneticist it is a group of different entities, familial or sporadic. Familial history, detailed clinical examination looking for extra-facial associated malformations, characteristics of the facial dysostosis, unilaterality or bilaterality and biological or radiological findings allow sometimes to identify a known syndrome. A bilateral and symetric dysostosis with predominant zygomatic and malar hypoplasia suggest the diagnosis of Treacher-Collins or Franceschetti syndrome or mandibulofacial dysostosis, particularly in the presence of positive familial history. Acral anomalies associated with facial dysostosis allow the distinction between Treacher-Collins syndrome and acrofacial dysostosis (Nager and Miller syndromes). Unilateral and bilateral asymmetrical anomalies, namely facioauriculovertebral syndrome, hemifacial microsomia, otomandibular dysostosis, no. 7 cleft, first branchial arch syndrome, Goldenhar syndrome were lumping together by Gorlin in 1990, who proposed to use the term "oculoauriculovertebral spectrum". This classification is the first step before genetic studies, who need homogeneous group of patients. Lastly recurrence risk can be evaluated and genetic counselling can be done only if a precise genetic diagnosis is known.

Abstract
Mandibular hypoplasia in the hemifacial microsomia have largely benefited from distraction techniques especially intraoral. In fact, these techniques are possible in the child, replacing him in a better morphological, psychological and functional configuration. They can redynamise growth and, in any case, diminish secondary distant effects. The authors, from precise criteria, propose a surgical classification to facilitate the therapeutic decision. Intraoral and sometimes bidirectional distraction, whose results are equivalent to external distraction, present numerous advantages that, in the majority of cases, make it preferred now to external distraction. Its three-dimensional (3D) effect on bone and soft tissues and the long term follow-up must be evaluated more objectively, as pre and post-distraction stereolithographic or 3D photogrammetric may get. It must be considered in the child as the first step of skeletic surgery preparing to a facilitated second step orthopedic, orthodontic or orthognathic after puberty. In the young adult, it is in competition with conventional surgery but the slow progressive process, kind with the temporo-mandibular joints, allows in mandibular asymmetries an adaptation having avoided the need for controlateral osteotomy or a bone graft.

Abstract
Pierre Robin sequence (PRS) consists of the nonrandom association of micrognathia, cleft palate (CP), and glossoptosis. It also includes respiratory and feeding difficulties that appear to be neurogenic rather than mechanical in causation. Genetic determinants are thought to underlie this functional and morphological entity, based on the existence of Mendelian syndromes with PRS, and the rare observations of familial nonsyndromic PRS, in which some of the affected individuals have isolated CP. We report the association of PRS with deletion 2q32.3-q33.2 due to an unbalanced reciprocal translocation 46,XX, t(2;21), del 2(q32.3q33.2), and we refine the deletion interval with regard to YAC probes and polymorphic DNA markers. The deletion was shown to be flanked by D2S369 (telomeric) and D2S315 (centromeric), thus it maps to a recently determined chromosomal region known to be nonrandomly associated with CP. This observation supports the hypothesis for the genetic bases of nonsyndromic PRS, strengthens its possible genetic association with isolated CP, and provides a candidate PRS locus, in chromosomal region 2q32.3-q33.2.

Abstract
From an experience in osteogenic distraction techniques acquired since 1993 and facing a case of retromandible, the authors have tried to define the criteria leading them to suggest a distraction rather a classical surgical procedure. The selection of the patient is based upon the age, the significance of the advancement, the asymmetry of the advancement and the former existence of a temporomandibular joint degenerative disease. Monitoring the distraction, in particular with per- and post-distraction orthodontics, remains complicated. The overcorrection and the reduction of recurrences after advancement using distraction remain openly discussed.

Abstract
OBJECTIVE Presentation of a specific surgical technique of vertical alveolar ridge distraction performed on an alveolar bone graft 1 year after the primary grafting procedure designed to correct a labioalveolar cleft. The graft had not obtained the results desired and presented heavily scarred mucosal tissue. TECHNIQUE A dental implant placed within the graft once it has been entirely freed by osteotomies functions as an endless screw. To avoid vascular risk, the alveolar bone graft is detached as a whole along its total height. Consequently, no bone remains above it to provide support for a conventional alveolar distractor. An osteosynthetic miniplate, fastened in a horizontal position beneath the nasal mucosae above the graft, is used to replace the missing bony support and to stabilize the implant, which activates the distraction process. PATIENT This study is based on our first clinical case with a follow-up of 18 months at present. RESULT A vertical displacement of the entire graft was achieved, including its attached mucosal layer, which repositioned both bone and mucosa on a far better level in the cleft area. Thus, a normal length of abutment was obtained permitting prosthetic rehabilitation based on the same endosseous implant, which was left in place within the graft. CONCLUSION This technique may prove particularly helpful in certain cases in which a primary alveolar bone grafting procedure has produced borderline results. In such cases, on the one hand, neither the reasonably satisfactory volume of the bone graft itself nor the poor quality of its scarred mucosal tissue argue in favor of a secondary grafting procedure. On the other hand, it is impossible to resort to currently available alveolar distracters since our choice of techniques leaves no bone support above the graft.

Abstract
Beckwith-Wiedemann syndrome (BWS) is an overgrowth disorder involving developmental abnormalities, tissue and organ hyperplasia and an increased risk of embryonal tumours (most commonly Wilms tumour). This multigenic disorder is caused by dysregulation of the expression of imprinted genes in the 11p15 chromosomal region. Molecular diagnosis of BWS is currently difficult, mostly due to the large spectrum of genetic and epigenetic abnormalities. The other difficulty in managing BWS is the identification of patients at risk of tumour. An imprinted antisense transcript within KCNQ1, called KCNQ1OT (also known as LIT1), was recently shown to be normally expressed from the paternal allele. A loss of imprinting of the KCNQ1OT gene, associated with the loss of maternal allele-specific methylation of the differentially methylated region KvDMR1 has been described in BWS patients. The principal aim of this study was to evaluate the usefulness of KvDMR1 methylation analysis of leukocyte DNA for the diagnosis of BWS. The allelic status of the 11p15 region and the methylation status of the KCNQ1OT and H19 genes were investigated in leukocyte DNA from 97 patients referred for BWS and classified into two groups according to clinical data: complete BWS (CBWS) (n=61) and incomplete BWS (IBWS) (n=36). Fifty-eight (60%) patients (39/61 CBWS and 19/36 IBWS) displayed abnormal demethylation of KvDMR1. In 11 of the 56 informative cases, demethylation of KvDMR1 was related to 11p15 uniparental disomy (UPD) (nine CBWS and two IBWS). Thirteen of the 39 patients with normal methylation of KvDMR1 displayed hypermethylation of the H19 gene. These 13 patients included two siblings with 11p15 trisomy. These results show that analysis of the methylation status of KvDMR1 and the H19 gene in leukocyte DNA is useful in the diagnosis of 11p15-related overgrowth syndromes, resulting in the diagnosis of BWS in more than 70% of investigated patients. We also evaluated clinical and molecular features as prognostic factors for tumour and showed that mosaicism for 11p15 UPD and hypermethylation of the H19 gene in blood cells were associated with an increased risk of tumour.

Abstract
Beckwith-Wiedemann syndrome (BWS) is an overgrowth disorder involving developmental anomalies, tissue and organ hyperplasia and an increased risk of embryonic tumours (most commonly Wilms' tumour). This multigenic disorder is caused by dysregulation of the expression of imprinted genes in the 11p15 chromosomal region. It may involve paternal uniparental disomy (UPD), loss of imprinting of the IGF2 gene, maternal inherited translocations and trisomy with paternal duplication. Recently, a small proportion of BWS patients has been shown to have a mutation in the paternal imprinted p57(KIP2) gene, which encodes a cyclin-dependent kinase inhibitor and negatively regulates cell proliferation. We screened for p57(KIP2) gene mutations in 21 BWS patients with no 11p15 UPD in leucocyte DNA. All patients had a phenotype typical of BWS. We analysed the entire coding sequence of p57(KIP2), including intron-exon boundaries, by direct sequencing of five PCR-amplified fragments. No mutation was found in the p57(KIP2) gene. Our results are consistent with those of previous studies showing that mutation of p57(KIP2) is infrequent in BWS. Thus, other mechanisms of p57(KIP2) silencing (imprinting errors) and/or other 11p15 genes are probably involved in the pathogenesis of BWS.

Abstract
Polysomnography, electromyography (EMG) of the face, tongue, and soft palate, blink reflexes (BRs), EMG during bottle-feeding, and brainstem auditory evoked responses (BAERs) were performed in 25 newborn babies with isolated Pierre Robin sequence (PRS) to aid in evaluation and management. Obstructive apneas were found in 23/24 patients (the 25th having undergone tracheotomy). Number and duration of central respiratory pauses were always normal, as well as electroencephalographic and clinical organization of sleep stages. EMG recruitment pattern in facial and lingual muscles, and BRs were normal in all cases. EMG recruitment pattern in muscles of the soft palate was normal in 14/25 patients, showed a reduced average amplitude with short-duration and low amplitude motor unit potentials in 10/25, and showed signs of denervation in 1/25. EMG during bottle-feeding showed sucking-swallowing disorders in 20/25 patients. BAERs showed a bilateral conductive impairment with increased latencies and thresholds in 5/19 patients, but with normal and symmetric I-III and I-V interpeak latencies in 19/19. These neurophysiological findings suggest that in isolated PRS a dysfunction of the lingual and pharyngeal motor organization exists without any structural impairment in brainstem nuclei and pathways.

Abstract
PURPOSE To analyze arteriovenous malformations (AVMs) of maxillo-mandibular arcades seen in our department since 1977, and to determine adequate treatment. MATERIAL AND METHODS Fourteen AVMs were reviewed to determine their revelation, their semiology, the treatment applied and the results that could be obtained. All these lesions were true AV shunts involving bone with or without soft tissue extension. RESULTS Eight patients belonged to the pediatric population. Six lesions were maxillary and 8 mandibular. All lesions were revealed during or after puberty by local swelling, pain, mass effect or bruit. Hemorrhage was the most frequent (71%) symptom. Teeth instability was detected in all these patients and was origin of the bleeding. The lesions were suspected clinically and confirmed radiologically. Angiography analyzed properly the architecture of the lesion (4 arteriovenous fistulas). Embolization was the clinical treatment in all patients: particles helped to stabilize the acute situations but failed to offer stable results, necessitating complementary embolizations and/or surgery (hemimandibulectomy in 2 patients). The use of acrylic glue (Histoacryl), injected percutaneously (5 patients), or transarterially in the AVM (4 patients)) provided cure in 6 of these lesions (43%) and long term stabilization for all the other AVMs. Teeth extraction could be performed thereafter in good conditions. Antibiotics and anti-inflammatory treatment helped to stabilize the evolutive risk of these lesions. CONCLUSION Embolization is the therapy of choice in these lesions. Appropriate use of glue offers a high rate of cure and/or clinical stabilizations and avoids unneeded surgery.

Abstract
This report describes the experience of the Trousseau Hospital, Paris, France, with distraction osteogenesis of the mandible using an intraoral distraction device. From 1993 to 1998, 26 paediatric patients with mandibular hypoplasia underwent distraction of the mandible using the Leibinger Intraoral Distractor. The majority of the patients had hemifacial microsomia. Distraction was performed at a rate of 1 mm a day following complete osteotomy of the mandible. A mean of 15 mm of distraction was obtained. In conjunction with combined orthodontic management, satisfactory morphologic results were achieved in the majority of patients with good facial symmetry, adequate occlusal relationships and balanced maxillary mandibular relationships. Radiographic evaluation revealed that substantial new bone formation and remodelling was induced by the intraoral distraction along the entire hemimandible on the distracted side and that this contributed significantly to the aesthetically pleasing clinical results.

Abstract
van der Woude syndrome (vWS, MIM 119300) is a rare autosomal dominant clefting condition with cardinal features of mucous cysts (lower-lip pits) and clefts to the lip and/or palate. The vWS gene has been assigned to a locus in 1q32-q41 by linkage analysis and physical mapping. We have investigated 5 novel vWS families through probands attended for cleft lip and/or palate repair at the Department of Maxillofacial Surgery of Hôpital Trousseau, Paris, in order to tentatively refine the genetic map of the vWS region in 1q32-q41 and possibly identify unlinked pedigrees. Linkage analysis was carried out to 6 microsatellite markers (D1S249, D1S425, D1S491, D1S205, D1S414, D1S425), yielding a maximum cumulative LOD score of Z = 3.27 at theta = 0.00 for D1S245. The innermost four markers were found to be tightly linked to one another, with no evidence for recombination. Our results support linkage of vWS within a region of tightly linked markers and do not favour locus heterogeneity of the disease trait.

Abstract
In children, mandibular swelling associated with an X-ray bone osteolysis may correspond to tumoral or infection diseases. Circumscribed osteitis of a child's mandibula, with no dental etiology occurs around 7-years of age, adjacent to a healthy first molar. Five cases reports were analyzed. Clinically, it is a bone swelling of the mandibula's lateral cortical associated with a soft tissue swelling. X-ray signs were not specific but all cases showed a bone lacuna with sharp outlines. Such clinical and X-ray signs strongly suggest diagnosis of osteitis which has a higher incidence than malignant tumors. The lack of dental pathology suggests bloodstream dissemination from another localized sepsis. Surgical removal of pathologic bone in addition to antibiotics (6 or 8 weeks) appears to be an effective treatment.

Abstract
Twelve arteriovenous malformations of the dental arcades (AVMDAs) (seven mandibular and five maxillary) were seen in our institution between 1977 and 1997. All these lesions consisted of true arteriovenous shunts (of either nidus or fistulous type) involving the bone, with or without soft tissue extension. Haemorrhage was present in eight patients (67%); either torrential, necessitating emergency embolization, or recurrent and progressive. Teeth instability was detected in all patients and was the origin of the bleeding. All lesions were embolized. Lesions in nine patients were embolized with Polyvinyl Alcohol Particles (PVA): this helped to stabilize the situation but could not avoid recurrences in all patients, necessitating complementary embolizations and or surgery. The use of acrylic glue (N-Butyl-Cyano-Acrylate [NBCA] Histoacryl) as the embolic agent has changed the results obtained tremendously. Eight patients have been treated with NBCA (five as complementary therapy to PVA during later sessions and three at the first attempt); injection either via the transarterial route or direct transcutaneous puncture (four patients) achieved a cure in four of these lesions (34%) with stability at long-term follow-up of all the other AVMs. Embolization with glue represents the therapy of choice in these sometimes life-threatening lesions, achieving a cure if directed towards the osseous venous lakes. Surgery, often leading to facial mutilation and necessitating massive reconstruction should be avoided nowadays, at least as the initial therapy.
