Endoscopic dissection of dura and craniotomy with minimal trephines: a preliminary series.
1998
The first nine clinical cases using endoscopic dissection of dura and craniotomy with minimal trephines were performed from June to August 1997 after trial dissection of 19 fresh cadavers conducted at the University of Brno's Pathology Institute in the Czech Republic. These procedures involved the refinement of craniofacial and intracranial surgical techniques using the endoscope and prototype instruments. These dissections demonstrated that intracranial structures can be explored using an endoscope without encumbrance, and that major craniofacial surgeries may also be performed with minor incisions and minimal craniotomies. Furthermore, we seek to illustrate that use of the endoscope in cr…
Boy with pseudohypoparathyroidism type 1a caused byGNASgene mutation (deltaN377), Crouzon-like craniosynostosis, and severe trauma-induced bleeding
2009
We report on a 6-month-old boy with craniosynostosis, pseudohypoparathyroidism type 1a (PHP1A), and a GNAS gene mutation. He had synostoses of the coronal, frontal, and sagittal sutures, brachyturricephaly, and hydrocephaly. He also had congenital hypothyroidism, round face, full cheeks, shortness of limbs, mild developmental delay, and muscular hypotonia. Because of progressive hydrocephaly, the synostosis was corrected surgically but circulatory decompensation led to disseminated intravascular coagulation and cerebral infarctions. Our patient died 8 days later. Postmortem molecular studies of GNAS, the gene for guanine nucleotide-binding protein, alpha-stimulating activity polypeptide (ge…
Q289P mutation in the FGFR2 gene: first report in a patient with type 1 Pfeiffer syndrome.
2008
When normal development and growth of the calvarial sutures is disrupted, craniosynostosis (premature calvarial suture fusion) may result. Classical craniosynostosis syndromes are autosomal dominant traits and include Apert, Pfeiffer, Crouzon, Jackson-Weiss, and Saethre-Chotzen syndromes. In these conditions, there is premature fusion of skull bones leading to an abnormal head shape, ocular hypertelorism with proptosis, and midface hypoplasia. It is known that mutations in the fibroblast growth factor receptors 1, 2, and 3 cause craniosynostosis. We report on a child with a clinically diagnosed Pfeiffer syndrome that shows the missense point mutation Q289P in exon 8 of the FGFR2 gene. This …
Nonsurgical treatment of an adult with skeletal Class III malocclusion, anterior crossbite, and an impacted canine
2021
Class III malocclusion presents some complexity in terms of diagnosis and treatment and affects not only the jaws but the whole craniofacial complex. Besides, functional forward displacement of the mandible may be diagnosed in a patient presenting Class III malocclusion, as the 2 entities are not incompatible or mutually exclusive. This case report describes the multidisciplinary, nonsurgical, orthodontic treatment of an adult patient with a skeletal Class III malocclusion, anterior crossbite, and a palatally impacted canine, treated with fixed appliances and skeletal anchorage. To upright the mandibular molars, distalize the whole mandibular arch, and avoid excessive inclination of maxilla…
Osteogenesis imperfecta type III : oral, craniofacial characteristics and atypical radiographic findings oral
2021
Osteogenesis imperfecta (OI) is a disease characterized by decreased bone mineral density, causing susceptibility to bone fractures by mild trauma and bone deformities. The aim of this study was to describe an osteogenesis imperfecta type III clinical case, its craniofacial and oral changes as well as its atypical radiographic findings. An eighteen-year-old, male patient diagnosed with osteogenesis imperfecta type III was referred for dental evaluation; the clinical examination showed the craniofacial and oral changes of the disease such as triangular face, class III malocclusion, anterior open bite and posterior crossbite, dentinogenesis imperfecta presenting amber discoloration. The radio…
An Annotated History of Craniofacial Surgery and Intentional Cranial Deformation
2001
The history of craniofacial surgery and the use of intentional cranial deformation is a long and varied one. Researching some of the earliest medical writings and reviews of early terracotta and stone figures from throughout the world clearly revealed that these two forms of treatment were widely extant. Intentional cranial deformation was used for a number of reasons including beautification, tribal identification, and social stature. The development of craniofacial surgery is a more modern practice and its historical evolution is reviewed in the context of techniques and the personalities involved.
Hyoid bone position in different facial skeletal patterns
2018
Background Hyoid bone plays a significant role in physiological functions of craniofacial region and it’s position adapts to changes of the head. The purpose of this study was to determine the position of the hyoid bone among subjects with class I, class II and class III skeletal patterns and evaluate the gender differences. Material and Methods One hundred and ten lateral cephalograms (59 females and 51 males) from different skeletal patterns (class I, II and III) were selected. The skeletal patterns were determined according to ANB angle. Using MicroDicom software, different linear and angular measurements (6 variables) was carried out to determine the position of hyoid bone. Intraclass c…
Orthodontic treatment of patient with maxillofacial fibrous dysplasia : a case report
2019
Fibrous dysplasia is a benign skeletal disorder in which the normal bone and marrow are replaced by fibrous tissue and haphazardly distributed woven bone. The aim of this case report is to discuss the orthodontic treatment of a 13-year-old patient with fibrous dysplasia in the left maxilla. The patient had rotated maxillary second premolars, moderate crowding in both maxillary and mandibular arches with low maxillary frenal attachment. Orthodontic treatment was done with full fixed appliance and extraction of maxillary and mandibular third molars. Maxillary frenectomy and free gingival graft in mandibular anterior region were performed by a periodontist. The oral and maxillofacial surgery t…
Esthetic and functional oral makeover of a 3 year old cleft palate patient suffering from early childhood caries using unconventional techniques
2011
Cleft lip and palate (CL/P) are the most common congenital craniofacial anomalies. It has been observed that these children have a higher caries experience compared their non cleft counterparts. Early childhood caries results in early pulp involvement and gross destruction of the anterior and posterior teeth. This leads to decreased masticatory efficiency, difficulty in speech, compromised esthetics, development of abnormal tongue habits and subsequent malocclusion and psychological problems. The restoration of severely decayed deciduous teeth especially anteriors presents a special challenge to dentists, particularly in uncooperative children. The following case report documents the restor…
Craniofacial Signs, Symptoms and Orthodontic Objectives of Paediatric Obstructive Sleep Apnoea
2019
The study of craniofacial growth and development has a long history in the disciplines of Paediatric Dentistry and Orthodontics. Unbalanced facial growth is known to be causative for dental misalignment and malocclusion. However, historically, little emphasis has been placed on the possible link to obstructive sleep apnoea. Through greater understanding from contemporary studies and reflections from past research, we now are bringing to light the interrelationships of all proximal structures in the many chronic issues that ail our children.
