Osteogenesis imperfecta (OI) is a hereditary bone fragility disorder that in most patients is caused by mutations affecting collagen type I. Their typical oral and craneofacial characteristics (Dentinogenesis imperfecta type I and class III malocclusion), involve the dentist in the multidisciplinary team that treat these patients. It is usual to perform lateral skull radiographs for the orthodontic diagnosis. In addition, this radiograph is useful to analyse the junctional area between skull base and spine, that could be damaged in OI...

BACKGROUND: Osteochondromas (OCs) are rare in the craneofacial area (0.6%). We present 2 cases of OC of the mandibular condyle, emphasizing the surgical decision of each case. CASE 1: In a 48-year-old woman with facial asymmetry, left cross-bite, and mandible deviation to the left, a computerized tomographic (CT) scan confirmed the presence of a bony expansion of the right condyle. The clinical diagnosis was osteochondroma. The patient underwent condylectomy with costochondral reconstruction...

INTRODUCTION. Esthesioneuroblastoma (ENB) is a very uncommon malignant tumor with a neuroectodermal origin that usually involves the anterior cranial fossa and nasal cavity. OBJECTIVES. To review our experience in the management of ENB and assess the validity of the histopathological diagnosis, modality of treatment and prognostic factors of the disease comparing our findings with the literature. METHODS. A retrospective study of 11 cases with the diagnosis of esthesioneuroblastoma treated in our hospital between 2000 and 2008...

UNLABELLED: INTRODUCTION. Suitable approach to anterior cranial base is mandatory to get global satisfactory surgical outcomes. In the beginning it depends on the exactly anatomical position into the cranial fossa and tridimensional spread. Surgical approach implies the evaluation of the patient status, reconstructive options and surgical team experience. Subcranial approach is a safe surgical option in the treatment of frontal traumatic pathology. It allows adequate management of frontal sinus and its obliteration with easy radiologic follow-up...

It is considered that up to 20% of the craniosinostosis patients require secondary surgeries. Different techniques have been used in craneofacial surgery for the reconstruction of great osseous defects in pediatric patients for many years. This paper is about a new technique to obtain osseous graft for covering osseous cranial defects, using particulate bone, harvested from the patient calvarian using a hand-driven brace and covered with a fibrin adhesive. This is a very simple technique, which provides a great amount of bone from the patient himself, therefore producing a small morbidity...

Aneurysmal bone cysts are rare benign lesions of bone tissue, infrequent in craneofacial skeleton with regard to other structures like long bones or the spine. They are composed of sinusoidal and vascular spaces blood-filled and surrounded by fibrous tissue septa. We present a case of a 29-year-old Caucasian male with a big swelling in the left mandible associated to pain and rapid growth. He referred previous extraction of the left inferior third molar. On the X-ray study, an expansive multilocular and high vascularized bony lesion within the mandibular angle was observed...

The development of multidisciplinar Units for Craneofacial Surgery has led to a considerable decrease in morbidity even in the cases of more complex craniofacial syndromes. The use of minimally invasive techniques for the correction of some of these malformations allows the surgeon to minimize the incidence of complications by means of a decrease in the surgical time, blood salvage and shortening of postoperative hospitalization in comparison to conventional craniofacial techniques. Simple and milder craniosynostosis are best approached by these techniques and render the best results...

It has been reported that the arrival of primary olfactory axons is required to induce the development of the olfactory bulb (OB). On the other hand, the Sey(Neu)/Sey(Neu) mutant mouse (Small eye) has been previously described as a model for the absence of olfactory bulbs, owing to the lack of olfactory epithelium (OE). In the present report, we take advantage of this mutant and study a neural structure in the rostral pole of the telencephalon that phenotypically resembles the prospective OB. We named this formation olfactory bulb-like structure (OBLS)...

All functions that characteristically define each form of life are the consequence of the unpredictable process of evolution. The appearance around 300,000 years ago of a complex system of language allowed the homo sapiens to verbally express his thoughts, feelings and experiences in a narrative manner. Thus began the great and continuous development of knowledge and the subsequent post-biological improvement of cognitive functions as a consequence of the stimulation of brain plasticity. This complex process vas not rapid...

We report on our experience in the experimental induction of Neural Tube Defects (NTD) in the foetal rat by maternal administration of retinoic acid. The teratogen diluted in olive oil was administered in a single intragastric dose (125 mg/kg body weight) to pregnant rats (n = 31) on the 10th day of gestation. Pure olive oil was given to control rats (n = 9). The foetuses were recovered by caesarian section on the 20th day and prepared for morphological investigation. We have studied 201 experimental and 82 control animals...

We present a case of a child with important phenotypic abnormalities (retinoblastoma, hypoplasia of the thumbs and genital), as well as craneofacial and evident psychomotor retardation. The chromosomal study showed a interstitial delection of the long arms of a chromosome from D group. We try to correlate karyotypes and phenotype, telling about difficulties that this relation means insisting about the importance of knowing more cases of chromosome 13 delection. We also think that subbands analysis represents an important factor in this correlation...

Four cases which illustrate possibilities of a new field in craneofacial surgery are presented. Using certain surgical principles, various conditions whose previous treatment was unsastisfactory, can be corrected. Hope is thus given to many persons with severe facial deformities.

The therapy of facial fractures is aimed at an early definitive treatment. Exact repositioning of the fragments is first achieved by setting the right occlusion. Intermaxillary fixation is then performed by interdental arch bars reenforced with acrylic material and intermaxillary rubber bands or wire. The middle third of the face is mainly subjected to static forces. Fractures in this area are therefore set and fixated with interosseous wire ligatures. Craneofacial suspension is carried out by means of a craneofixateur extern...
