Pharyngeal function was studied in 31 patients with rheumatoid arthritis. Eighteen of these patients had dysphagia. Cervical spine abnormalities were present in 14. Destruction of the capitulum and/or ramus of the mandible was registered in 9. Pharyngeal dysfunction was revealed in 20. Patients with a vertical dislocation of the C1–C2 in relation to the occipital bone and patients with destruction of the capitulum and/or ramus of the mandible had an increased frequency of pharyngeal dysfunction. Pharyngeal dysfunction is thought to be due to mechanical factors and caused by derangements of mus

Abstract:

The Arhgap29 gene encodes Rho-GTPase-activating protein 29 (Arhgap29), which plays a crucial role in embryonic tissue development. Mutations in the Arhgap29 gene are significantly associated with non-syndromic cleft lip and palate (NSCL/P). Our study demonstrated that the deletion of Arhgap29 leads to syndromic cleft lip and palate (SCL/P) characteristics in mice, where, in addition to cleft palate, the mice exhibit craniofacial and systemic skeletal abnormalities. However, the mechanisms underlying these skeletal abnormalities remain unclear. Through micro-CT imaging, histological analysis, a

When compared to adults, the pattern of fractures and frequency of associated injuries are similar but the overall incidence is much lower.

Abstract:

Temporomandibular joint is a synovial articulation, formed by condyle of the mandible and glenoid (mandibular) fossa and articular eminence of temporal bone at the base of the skull. It differs from other joints of body because it shows the properties of both hinge and sliding joint so it also called as ginglymo-arthrodial joint. Temporomandibular joint abnormalities affect 5-12% of the population. The correct diagnosis of early abnormalities of this joint is of paramount importance because they can result in temporomandibular joint disorders. In the present article, a short insight is present

Abstract Apert syndrome is a rare autosomal dominant disorder characterized by craniofacial abnormalities, craniosynostosis and syndactyly. Nasotracheal intubation for a patient with Apert syndrome can be a challenge because of abnormal facial anatomy.

Nasotracheal intubation using a gastric tube and extubation using an airway exchange catheter proved useful in this case of airway compromise.

Abstract:

Pyknodysostosis is a rare disorder of skeletal dysplasia that is inherited as an autosomal recessive genetic trait. Several mutations have been found in the gene encoding cathepsin K - a lysosomal cysteine protease and the gene situated at 1q21. A mutation in this gene leads to loss of enzyme for osteoclastic activities responsible for the metabolism of skeletal system leading to defective bone remodeling and resorption and various other skeletal abnormalities. Here we report a case of 12 year old female from mid-western hilly region of Nepal with Pyknodysostosis having fracture femur and othe

Determine measurement of the type of dentoskeletal abnormality in malocclusion using cephalometric analysis. Steiner analysis is used because it is considered that the Sela tursica-nasion-point A (SNA) angle, Sela tursica-nasion-point B (SNB) used to describe the relationship between the maxilla and the mandible.

Abstract:

Abstract Cleidocranial dysostosis is a rare congenital skeletal disorder, associated with clavicular hypoplasia or aplasia, delayed closure of cranial fontanels, brachycephalic skull, delayed exfoliation of primary dentition, eruption of permanent teeth, and multiple supernumerary and morphologic abnormalities of the maxilla and mandible. The disorder is caused by mutation in the CBFA1 gene, on the short arm of chromosome 6p21. The prevalence of cleidocranial dysostosis is estimated one per million, without sex or ethnic group predilection. The purpose of this paper is to describe the orthodon

Abstract:

✓ Ossifying fibroma is a rare, benign, primary bone tumor that occurs most commonly in the mandible; a cranial vault location is extremely rare. In this report a case of symptomatic frontoparietotemporal ossifying fibroma with intracranial growth and cerebral displacement in a 12-year-old boy with neurofibromatosis type 1 (NF1) is described. Once excised the lesion did not recur. The skeletal system is frequently affected in NF1, and bone abnormalities are present in 50% to 70% of patients with this condition. The etiology of such lesions in NF1 is still controversal. To the authors' knowledge

The purpose of this article is to report a case of ossifying fibroma in the mandible associated with hyperparathyroid–jaw tumor syndrome, in a 46-year-old Caucasian female, surgically resected and reconstructed with iliac crest bone, followed by implant placement. This is a rare syndrome with an autosomal dominant pattern, with the development of primary hyperparathyroidism mainly due to parathyroid adenomas. Fibro-osseous lesions in the jaws can be present and can also precede the development of the endocrine disorder. As renal abnormalities and uterine tumors can develop, an interdisciplinar

Abstract:

Mucopolysaccharidoses (MPS) are a family of genetic diseases associated with a deficiency of alpha-L iduronidase, which causes a lack of catabolism of glycosaminoglycans (GAGs). Therefore, the accumulation of GAGs determines a wide spectrum of symptoms, typically found in a few syndromes like Hurler syndrome (HS). Among other specific manifestations, craniofacial abnormalities are crucial for the characterization of this syndrome. Ameloblastoma is a rare, benign, slow-growing, odontogenic tumor usually located in the mandible. Clear risk factors for the development of ameloblastoma remain unkn

Craniofacial development requires extremely fine-tuned developmental coordination of multiple specialized tissues. It has been evidenced that a folate deficiency (vitamin B9), or its synthetic form, folic acid (FA), in maternal diet could trigger multiple craniofacial malformations as oral clefts, tongue, or mandible abnormalities. In this study, a folic acid-deficient (FAD) diet was administered to eight-week-old C57/BL/6J female mouse for 2–16 weeks. The head symmetry, palate and nasal region were studied in 24 control and 260 experimental fetuses. Our results showed a significant reduction
