Growth potential in suture bone inlay grafts: a comparison of vascularized and free calvarial bone grafts in order to determine the effects of such grafts on craniofacial development. Plast Reconstr Surg 1987; 79:1-11. The authors wished to determine the growth potential of vascularized and free calvarial bone grafts in order to determine the effects of such grafts on craniofacial development. Collie dogs served as the experi- mental model; in a group of six dogs, a skeletal defect was created in the right zygomaticomaxillary suture area, the ipsilateral zygomatic arch was resected, and a calvarial bone graft from the coronal suture pedicled on the temporalis muscle was fixed in the defect. In the control group consisting of five dogs an identical defect was created, the zygomatic arch resected and muscle dissected, but a free calvarial bone graft from the coronal suture area was transplanted and fixed in place. Greta Gutta-percha radiopaque points were used to determine transsutural growth on serial cephalograms. Direct osteometry was also used to evaluate the results of the free and vascularized calvarial bone grafts. No growth occurred in the free grafts. Less growth restriction occurred with the vascularized grafts. Deformity of the skull resulted from denuding in the temporoparietal region of periosteum when the flaps were raised. Transsutural growth in the vascularized grafts persisted for the duration of maxillary development, despite cessation of skeletal growth at the calvarial donor sites. (Trier) Reprints: Dr. O.

Growth potential in onlay bone grafts: a com- parison of vascularized and free calvarial bone and suture bone grafts. Plast Reconstr Surg 1987; 79:12-20. This study was designed to compare the potential for appositional bone growth in vascularized and free onlay calvarial bone grafts. Grafts were applied as supraperiosteal onlays. The studies were done in 8 week-old beagle puppies. Pedicled bone grafts were transplanted on one side, whereas on the other side free grafts were performed. Sides having pedicled grafts and free grafts were alternated. New bone formation was evaluated by triple-color fluorochrome labeling. The length, width, and thickness of each bone graft was recorded at the time of grafting and again at 28 weeks of age, at the time of harvesting of the grafts. The percent growth in every dimension was significantly greater in vascularized grafts as compared with free grafts. The architecture of vascularized grafts was preserved, whereas free grafts contained multiple small resorption cavities. Vascularized grafts showed active new bone formation, whereas free grafts did not. Active new bone formation was evident in the vascularized grafts, but bone resorption and delay in sub- periosteal new bone formation was noted in the free grafts. (Trier) Reprints: Dr. O.

Single maxillary central incisor and coloboma in hypomelanosis of Ito. Clin Genet 1987; 31:370-373. The combination of an iris coloboma, single deciduous maxillary incisor, and Incontinentia Pigmenti Achromians (IPA) is reported in a 16-month-old black female. Serial examination during the first year showed a head circumference consistently at the third percentile, despite weight and length at the fiftieth percentile. There was evidence of delayed motor development. At age 14 months, her third tooth erupted-a single maxillary central incisor-followed by the laterals. A dolichocephalic skull with increased frontal illumina- tions, depressed nasal bridge, and torus palatinus was noted. Spinal fusion of C-2 to C-3 was found, but 418 ABSTRACTS 419 seems not to have been associated with IPA. The authors point out that this unique sequence of abnormalities was not previously described in IPA. The authors suggest an etiology of faulty migration of neural crest cells early in uterine life or ectodermal-mesenchymal interaction at the cellular level. (Sarnas) Reprints: Dr. D.

Plast Reconstr Surg 1987; 80:185-194. The photographs of a consecutive series of 10 Oriental patients who underwent primary nasal recon- struction at the time of cleft lip repair are shown. The patients have all had only one operation and none underwent any subsequent revision. Lip repair was carried out by flap technique. Nasal reconstruction was performed by extending the superior buccal sulcus incision up along the frontal process of the maxilla, making an alar rim incision from columellar base to alar base, and splitting the ala into a skin and a chondrocutaneous layer (vestibular skin). Alar undermining is extensive: laterally to the alar-cheek area, medially including the columella, and between the medial crura down to the anterior nasal spine and the contralateral ala. Superior undermining extended to the level of the inner canthus. No transfixion sutures are used. The author depends on the thick nostril wall, postoperative scar tissue, and the normal position of the alar base to keep the alar arch elevated.

Craniofacial infection in 10 years of transcranial surgery. Plast Reconst Surg 1987; 80:213-223. An analysis of 170 patients undergoing transcranial procedures was carried out to determine the inci- dence of postoperative infection and its relationship to preoperative microbiology, surgical factors, antibiotic prophylaxis, and postoperative management. The age of patients varied between 5 weeks and 58 years. There were 131 children and 33 adults. The 170 operations were performed on 164 patients, since 6 patients had two transcranial procedures. Fifty-two percent of the patients had craniosynostoses. All craniofacial patients had preoperative microbiology swabs of their scalp, conjunctivae, nose, and throat. Antibiotic prophylaxis was carried out with alternating methicillin and ampicillin in the first 5 years. During the next 2 years, combined flucloxacillin and ampicillin were given for 48 hours after the procedure. In the final 2 years, flucloxacillin and metronidazole were given preoperatively and continued for 48 hours postoperatively. Six patients did not receive antibiotics. Infections occurred in 11 or 6.5 percent of the patients, with an infection rate in children of only 2.2 percent but of 23.5 percent in adults.

This syndrome is Pfeiffer syndrome; also called acrocephalosyndactyly type 5, which is divided into three sub-types. Type I Cloverleaf skull; is the classic Pfeiffer syndrome, with autosomal dominant transmission, often associated Craniosynostosis; with normal intelligence. Types II and III occur as sporadic cases in individuals who have Syndactyly; craniosynostosis with broad thumbs, broad big toes, ankylosis of the elbows and visceral Prenatal diagnosis abnormalities [2]. We report a case of Pfeiffer syndrome type II, discovered perinatally, which is distinguished from type III by the skull appearing like a cloverleaf, and we shall discuss the clinical, radiological and evolutive features and the advantage of prenatal diagnosis of this syndrome with a review of the literature. Observation The case involved a male premature baby born at 36 weeks of amenorrhoea with multiple deformities at birth. The parents were not blood-related and in good health who had two other boys and a girl with normal morphology.

    Bargale and Kiran Head & Face Medicine 2011, 7:19 http://www.head-face-med.com/content/7/1/19 HEAD & FACE MEDICINE CASEREPORT Open Access Non-syndromic occurrence of true generalized microdontia with mandibular mesiodens - a rare case Seema D Bargale* and Shital DP Kiran Abstract Abnormalities in size of teeth and number of teeth are occasionally recorded in clinical cases. True generalized microdontia is rare case in which all the teeth are smaller than normal. Mesiodens is commonly located in maxilary central incisor region and uncommon in the mandible. In the present case a 12 year-old boy was healthy; normal in appearance and the medical history was noncontributory. The patient was examined and found to have permanent teeth that were smaller than those of the average adult teeth. The true generalized microdontia was accompanied by mandibular mesiodens. This is a unique case report of non-syndromic association of mandibular hyperdontia with true generalized microdontia.

  • Otocephaly: Agnathia-Microstomia-Synotia Syndrome Tanya Kitova1, Borislav D Kitov2
    CASE REPORT Otocephaly: Agnathia-Microstomia-Synotia Syndrome Tanya Kitova1, Borislav D Kitov2 ABSTRACT The aim of the study is to present otocephaly, which is a rare congenital lethal malformation. Until this moment, only a little bit more than 100 cases worldwide were reported, and only 22 cases of prediagnosed otocephaly. Background: Otocephaly or agnathia-microstomia-synotia syndrome (SAMS) is characterized by agenesis of mandible (agnathia), disposition or fusion of the auricle (synotia), microstomia, and complete or partial lack of language (aglossia), which often ends up lethal. Case description: A 499.7 g male fetus was obtained after a therapeutic abortion during the 23rd gestational week at the Center for Maternity and Neonatology, Embryo-fetopathology Clinic, Tunis, Tunisia. The mother is an 18-year-old with close relative marriage with first-degree incest, primigravida. Examination of the fetus revealed microcephaly with craniosynostosis, hypertelorism, closed eyelid exophthalmos, one nostril, point microstomia, mandibular agenesis, bilateral, and auditory cysts of neck. The ears are located at the level of the neck. A study of the brain and the base of the skull revealed holoprosencephaly and sphenoid bone agenesis. There are no internal organ abnormalities. Conclusion: In cases where, at the end of the second trimester of pregnancy, polyhydramnios is detected, inability to visualize the mandible, and malposition of ears, otocephaly should be suspected. In these cases, the decision to interrupt pregnancy should be taken by a multidisciplinary team, after an magnetic resonance imaging, which is much better in visualizing location of the ears and other facial malformations and the presence of other associated anomalies.

These disorders can be divided into metabolic and developmental categories based on their molecular etiologies. Metabolic megalencephalies are mostly caused by genetic defects in cellular metabolism, whereas developmental megalencephalies have recently been shown to be caused by alterations in signaling pathways that regulate neuronal replication, growth, and migration.

  • Level Estimates of Maternal Smoking and Nicotine Replacement Therapy During Pregnancy
    Using primary care data to assess population- level estimates of maternal smoking and nicotine replacement therapy during pregnancy Nafeesa Nooruddin Dhalwani BSc MSc Thesis submitted to the University of Nottingham for the degree of Doctor of Philosophy November 2014 ABSTRACT Background: Smoking in pregnancy is the most significant preventable cause of poor health outcomes for women and their babies and, therefore, is a major public health concern. In the UK there is a wide range of interventions and support for pregnant women who want to quit. One of these is nicotine replacement therapy (NRT) which has been widely available for retail purchase and prescribing to pregnant women since 2005. However, measures of NRT prescribing in pregnant women are scarce. These measures are vital to assess its usefulness in smoking cessation during pregnancy at a population level. Furthermore, evidence of NRT safety in pregnancy for the mother and child’s health so far is nebulous, with existing studies being small or using retrospectively reported exposures. Aims and Objectives: The main aim of this work was to assess population- level estimates of maternal smoking and NRT prescribing in pregnancy and the safety of NRT for both the mother and the child in the UK. Currently, the only population-level data on UK maternal smoking are from repeated cross-sectional surveys or routinely collected maternity data during pregnancy or at delivery. These obtain information at one point in time, and there are no population-level data on NRT use available. As a novel approach, therefore, this thesis used the routinely collected primary care data that are currently available for approximately 6% of the UK population and provide longitudinal/prospectively recorded information throughout pregnancy.

  • Appendix A: Organisation of a Craniofacial Unit
    Appendix A: Organisation of a Craniofacial Unit The requirements of patients with craniofacial abnormalities are very complex and demand a multidisciplinary approach. Many body systems are affected, and every detail of patient management has to be given due attention. Care begins at birth and continues until the patient and his family have been relieved of the burden of the anomaly. A team is needed, capable of delivering expert patient care, and representative of all the relevant disciplines. Data, in the form of histories, physical examinations, and special investigations, are needed in planning treatment, and such data should be used to the maximum scientific effect, to improve present methods of management, still far from satisfactory, and to expand knowledge of the biology of cranial growth and its disorders. Craniofacial Units Sporadic craniofacial procedures performed by a surgeon on an irregular basis invite disaster. Tessier (1971a) estimated that each craniofacial centre should serve a population of 10 to 20 million people, provided that the team performed only craniofacial surgery and treated at least 50 new cases annually. As a consequence of Tessier's example and teaching there are now centres of acknowledged excellence in Paris and Nancy, attracting patients not only from France but also from North Africa and elsewhere. In North America there are now important craniofacial centres in Philadelphia, New York, Boston, Toronto, and Mexico City. Munro (1975) proposed that North America should be divided into seven regions, six for the United States and one for Canada, each serving populations of 20 to 40 million people. He believed that such centres would allow a concentration of multidisciplinary skills and accumulation of experience in the treatment of craniofacial anomalies.
