Background: Arnold Chiari malformation (ACM) is characterized by an anatomical defect at the base of the skull where the cerebellum and the spinal cord herniate through the foramen magnum into the cervical spinal canal. Among the subtypes of the condition, ACM type I (ACM-I) is particularly outstanding because of the severity of symptoms. This study aimed to analyze the orofacial clinical manifestations of patients with ACM-I, and discuss their demographic distribution and clinical features in light of the literature...

Thomas Malthus (1766-1834), distinguished English professor, is the father of modern demography and the most famous harelip carrier of history. Much is known of his orofacial cleft but nothing regarding its mysterious surgical correction. An 1833 portrait of Malthus by John Linnell, finished when he considered himself "handsome enough," for sitting does not show any upper lip scar. When this surgery took place? Although technically feasible in the 19th century, surgery of cleft lip and palate was complicated...

The relationship of the maxillary incisor to forehead position and angulation may be a predictor for the esthetic antero-posterior maxillary position in orthognathic surgery, but this has not been fully explored in the existing literature. Additionally, this analysis requires a lateral smiling photograph, which is not typically included in orthodontic/orthognathic records. This is a bidirectional study of Caucasian orthodontic patients with malocclusions correctable with nonsurgical and nonextraction treatment...

Chronic orofacial pain syndromes represent a diagnostic challenge for any practitioner. Patients are frequently misdiagnosed or attribute their pain to a prior event such as a dental procedure, ENT problem or facial trauma. Psychiatric symptoms of depression and anxiety are prevalent in this population and compound the diagnostic conundrum. Treatment is less effective than in other pain syndromes and thus often requires a multidisciplinary approach to address the many facets of these conditions.

REVIEW
So-Young Park, Kwang-Suk Seo, Myong-Hwan Karm
In the field of orofacial surgery, a red blood cell transfusion (RBCT) is occasionally required during double jaw and oral cancer surgery. However, the question remains whether the effect of RBCT during the perioperative period is beneficial or harmful. The answer to this question remains challenging. In the field of orofacial surgery, transfusion is performed for the purpose of oxygen transfer to hypoxic tissues and plasma volume expansion when there is bleeding. However, there are various risks, such as infectious complications (viral and bacterial), transfusion-related acute lung injury, ABO and non-ABO associated hemolytic transfusion reactions, febrile non-hemolytic transfusion reactions, transfusion associated graft-versus-host disease, transfusion associated circulatory overload, and hypersensitivity transfusion reaction including anaphylaxis and transfusion-related immune-modulation...

A valuable approach to understand how individual and population genetic differences can predispose to disease is to assess the impact of genetic variants on cellular functions (e.g., gene expression) of cell and tissue types related to pathological states. To understand the genetic basis of nonsyndromic cleft lip with or without cleft palate (NSCL/P) susceptibility, a complex and highly prevalent congenital malformation, we searched for genetic variants with a regulatory role in a disease-related tissue, the lip muscle (orbicularis oris muscle [OOM]), of affected individuals...
