Objective: Achieving postsurgical skeletal stability is crucial for successful outcomes and patient satisfaction. Precision maxillofacial surgery, which integrates precision techniques with minimally invasive approaches, is increasingly recognized for its potential to enhance long-term stability and reduce surgical risks and complications. This study aimed to comprehensively evaluate the impact of fixation techniques (2 vs 4 plates) during Le Fort I osteotomy in orthognathic surgery on skeletal stability.

Bibliometric analysis serves as a potent tool for deciphering the intricacies of scholarly communication and academic impact, contributing to an observable surge in publications of this nature. The objective of this study is to conduct a bibliometric analysis of self-citation in Maxillofacial Surgery (MFS) literature. The retrospective study adheres to the principles outlined in the Leiden Manifesto, utilizing Web of Science and Scopus databases for a robust analysis.

The present paper provides a historical context for chaos theory, originating in the 1960s with Edward Norton Lorenz's efforts to predict weather patterns. It introduces chaos theory, fractal geometry, nonlinear dynamics, and the butterfly effect, highlighting their exploration of complex systems. The authors aim to bridge the gap between chaos theory and oral and maxillofacial surgery (OMFS) through a literature review, exploring its applications and emphasizing the prevention of minor deviations in OMFS to avoid significant consequences.

Article Synopsis
  • The study examines how the facial aesthetics of female celebrities influence societal standards of attractiveness, utilizing artificial intelligence to analyze profile views.
  • It involved a cohort of 115 female celebrities and identified key facial ratios, revealing racial variations in features, such as a general mean golden ratio that differed among African, Asian, Latin, and Caucasian celebrities.
  • The research concluded that while facial symmetry is desirable, it is not essential; instead, specific ratios and angles, like a zygomatic-to-mandibular width ratio close to 80% and a chin angle of approximately 138°, define an attractive female face across different races.

Objective: Developing the skills of a proficient surgeon with a deep understanding of force requires extensive training and repetitive practice. Traditionally, dental students and surgical trainees observed and participated in procedures using models, animals, or cadavers under expert supervision before performing the procedures independently. To address these challenges, interactive simulators with visuo-haptic features have been introduced in surgical training, providing visual and tactile feedback that replicates the sense of touch through applied forces, vibrations, or motions.

Hemifacial microsomia (HFM) is a complex congenital malformation with an extremely variable phenotypic presentation. It usually involves structures of the first and second pharyngeal arches. Anomalies of the cardiac, pulmonary, renal, and gastrointestinal systems are present, but the main characteristic is the mandibular hypoplasia.

Late reconstructions of gunshot wounds (GSWs) in the orbital area are a true challenge to the oral and maxillofacial surgeon. Usually, the wall defects are large in size and commonly present loss of orbital volume, which can cause ocular dystopia. The only exceptions are when there is an explosion of the orbital walls-that is, blow-out fractures.

Sturge-Weber syndrome is a developmental condition characterized by hamartomatous vascular proliferation involving the tissues of the brain and face. Hemangiomatous proliferations and arterial venous malformations are common intraoral alterations that may be fatal due to incontrollable bleeding when performing surgical procedures in the face. The goal of this case report is to present the management of a 21-year-old woman with Sturge-Weber syndrome in whom it was necessary to perform embolization guided by computed tomography angiography before multiple tooth extractions.

Temporomandibular joint (TMJ) ankylosis is a disease commonly associated with facial trauma, especially in the condylar region. Described as a heterotopic bone growth that causes mouth opening limitation, it may occur in trauma cases misdiagnosed or mistreated. We present the case of a 37-year-old female, with decreased mouth opening after three traumas in the region of the right condyle by a motorcycle accident.

Objective: The aim of this study was to report on clinical experience in Brazil in the dental treatment and the oral conditions of a group of patients with hereditary angioedema (HAE).

Study Design: The study analyzed demographic data, type of HAE, intensity of attacks, long-term and short-term prophylaxis, dental procedures, and occurrence of crises after the procedures were performed. Radiographic evaluation of the number of teeth and bone loss was also performed.
