Introduction: regenerative medicine is a charming area of research in the biomedical sciences, it constitute a promising therapeutic alternative for expansion in the treatment of skeletal bone defects, including the craniofacial complex. Objective: to review the literature on the use of regenerative medicine in the treatment of craniofacial bone defects. Methods: a review was conducted in the period from June to July 2013. Impact journals from Web of Sciencies related to this topic were evaluated (28 journals) and 2 Cuban magazines. Were consulted databases referativos systems such as MEDLINE, PubMed and SciELO with the use of descriptors such as craniofacial bone defects, craniofacial regenerative medicine, bone regeneration, bone reconstruction, bone scaffolds and its Spanish counterparts. We included articles in English and Spanish and publications of the last five year, except for one. 115 articles were obtained, confined the study to 51 that focused this issue more comprehensively. A book was reviewed. Results: by analyzing the behavior of the articles on the subject of study with respect to their representation in the various scientific journals where they were published, 11.8% of them corresponded, respectively, to the Journal of Oral and Maxillofacial Surgery and The Journal of Craniofacial Surgery. The remaining items were evenly distributed among the other magazines. Conclusions: all these publications agree pronounce that we have entered a new era in orofacial bone regeneration, where improved osteoinductive materials, CM based therapies, among other elements of this branch of research, can be used to improve and accelerate desirable clinical outcomes in areas such as trauma, distraction, craniofacial defects, critical size and excision of pathological atrophy alveolar osteonecrosis and elevated maxillary sinus mucosa(AU)

Limbal dermoid in Nager acrofacial dysostosis: A rare case report.

Nager syndrome, also called preaxial acrofacial dysostosis, comprises two groups of defects involving the limbs and craniofacial region, respectively. This syndrome is rare and only 70 cases have been reported in the literature. The exact cause of this syndrome is unknown, but there is indication that it is genetically based. Ocular manifestations of this syndrome include widely separated downward slanting eyes, absence of eyelashes, ptosis of upper eyelids and colobomas on the inner aspect of lower eyelids. We report limbal dermoid in a patient with Nager syndrome. We did not find such an association of “Limbal dermoid in Nager acrofacial dysostosis syndrome” on PubMed using Nager acrofacial dysostosis, limbal dermoid and ocular manifestations as the keywords.

Augmentation of craniofacial defects using alloplastic material / Técnica de aumento para la reparación de defectos craneofaciales usando materiales aloplásticos

BACKGROUND: Alloplastic materials are increasingly being used in augmentation of craniofacial defects because of its ready availability, good aesthetic outcome and absence of donor site morbidity. This paper highlights experience in the use of heat-cured acrylic in augmentation cranioplasty. SUBJECTS AND METHOD: The management of three patients with anterior skull defect who presented at the Dental and Maxillofacial Surgery Clinic of the Aminu Kano Teaching Hospital over a five-year period is presented. RESULTS: There was good aesthetic outcome in all the patients and no complications were recorded. CONCLUSION: Augmentation of craniofacial defects using customized prefabricated heat-cured acrylic provides patients with a durable, stable and structural repair ofcraniofacial defects with good aesthetic outcome.

ANTECEDENTES: Los materiales aloplásticos son usados cada vez más en la técnica de aumento para la reparación de defectos craneofaciales, debido a su disponibilidad inmediata, buen resultado estético y ausencia de morbosidad del sitio donante. Este trabajo destaca nuestra experiencia en el uso de acrílico curado por calor en las técnicas de aumento en la craneoplastia. SUJETOS Y MÉTODOS: Se describe el tratamiento de tres pacientes con defectos del cráneo anterior, que asistieron a la Clínica de Cirugía Maxilofacial y Dental del Hospital Docente Aminu Kano por un período de más de cinco años. RESULTADOS: Hubo un buen resultado estético en todos los pacientes y no se reportaron complicaciones. CONCLUSIÓN: La técnica de aumentación para los defectos craneofaciales, utilizando acrílico prefabricado curado con calor, proporciona a los pacientes una reparación duradera, estable y estructural de los defectos craneofaciales con buen resultado estético.

Effects of Consanguineous Marriages On Oral And Craniofacial Structures : A Study On Dental Patients In North India.

Background: Consanguinity describes a relationship between two people who share an ancestor, or share blood. These consanguineous marriages are a major risk to the health of offsprings till the extent that they can cause various craniofacial abnormalities, orofacial pigmentations and other abnormal birth defects. We conducted a study on patients visiting a dental college in North India to accesses the possible deleterious effects of consanguineous marriages on oral and craniofacial structures. Methodology: The study group comprised of all the patients visiting outpatient department of Kotiwal Dental college and Research centre, Moradabad in North India from March 2009 to February 2010. 200 patients showed positive history of consanguinity. They were carefully evaluated and all the diagnostic information was noted. Results: 66 out of 200 patients had systemic disorders like cardiovascular, pulmonary and renal disturbances. 56 patients had orofacial manifestations like orofacial pigmentations, craniofacial syndromes and occlusal abnormalities with or without systemic disorders. Conclusion:The prevalence of consanguineous marriages is still high. Consanguineous marriages are a major risk to the health of offsprings till the extent that they can cause various craniofacial abnormalities, orofacial pigmentations and other abnormal birth defects. They increase the autosomal recessive conditions through the expression of recessive deleterious alleles, especially in the offspring of first degree cousins
