When trauma bites back: a systematic review on direct orofacial macrotrauma and temporomandibular disorders.

Objectives: Temporomandibular disorders (TMD) are musculoskeletal conditions with a multifactorial aetiology. The predictive role of direct orofacial macrotrauma in the development of TMD is considered controversial. This systematic review aims to elucidate the association between direct orofacial macrotrauma and TMD, and to identify potential factors involved in this relationship.

Controversies in the Management of the Airway in Panfacial Fractures: A Literature Review and Algorithm Proposal.

Panfacial fractures are complex fractures involving multiple regions of the facial skeleton and may require multiple surgeries over a relatively short period. They are often associated with polytrauma and other injuries including neurotrauma, which require either immediate (ATLS) airway management, prolonged intubation, or repeated intubations for staged surgeries. The choice of airway for the surgical management of these fractures is difficult, as an assessment of the occlusion is required, and the central nasal complex and/or skull base may be involved, making classical orotracheal or nasotracheal intubation problematic.

Patient and practitioner perspectives on tooth extractions without clinical justification.

Background: Nondental factors (ie, financial, psychological, or cultural considerations) can play a role in extraction requests. The purpose of this study was to investigate whether patients' perspectives on extraction without a valid clinical indication align with those of practitioners.

Methods: Dentists from 3 centers for special oral health care, oral and maxillofacial surgeons (OMFS) from 3 hospitals in the Netherlands, and their patients participated in this prospective observational study.

Healthcare costs of different treatment options for condylar fractures.

Objective: As treatment options for condylar fractures have comparable outcomes, getting insight into associated costs is a first step towards implementing value-based healthcare (VBH). Therefore, we described the actual costs of the different treatment options (surgical, conservative, and expectative treatment) for condylar fractures. We expected surgical treatment to be the most expensive treatment.

Contact stress distribution after unilateral condylar fracture with angulation of the fractured part: A finite element model study.

After a fracture of the condyle, the head of the condyle is often pulled inwards, which causes the fractured part to angulate medially. This change can cause a disbalance in the masticatory system. The disbalance could lead to contact stress differences within the temporomandibular joints (TMJs) which might induce remodelling within the TMJ to restore the balance.

Changes in load distribution after unilateral condylar fracture: A finite element model study.

Objective: Premature dental contact on the fractured side and a contralateral open bite are signs of a unilaterally fractured condyle of the temporomandibular joint (TMJ). The lateral pterygoid muscle pulls the condyle inwards, causing angulation of the fractured part and shortening of the ramus. This imbalance after fracture might change the load in both TMJs and consequently induce remodeling.

The Effectiveness of Three-Dimensional Osteosynthesis Plates versus Conventional Plates for the Treatment of Skeletal Fractures: A Systematic Review and Meta-Analysis.

Purpose: To assess the difference between preformed anatomically shaped osteosynthesis plates and patient-specific implants versus conventional flat plates for the treatment of skeletal fractures in terms of anatomical reduction, operation time, approach, patient outcomes, and complications.

Material And Methods: MEDLINE (1950 to February 2023), EMBASE (1966 to February 2023), and the Cochrane Central Register of Controlled Trials (inception to February 2023) databases were searched. Eligible studies were randomised clinical trials, prospective controlled clinical trials, and prospective and retrospective cohort studies ( ≥ 10).

Load distribution after unilateral condylar fracture with shortening of the ramus: a finite element model study.

Objectives: After a fracture of the condyle, the fractured ramus is often shortened, which causes premature dental contact on the fractured side and a contralateral open bite. The imbalance could change the load in the temporomandibular joints (TMJs). This change could lead to remodelling of the TMJs to compensate for the imbalance in the masticatory system.

How dentists and oral and maxillofacial surgeons deal with tooth extraction without a valid clinical indication.

Objectives: This study pertains to a secondary data analysis aimed at determining differences between oral and maxillofacial surgeons (OMFSs) and dentists handling dental extractions without an evident clinical indication.

Study Design: A survey of 18 questions was conducted among 256 OMFSs in the Netherlands and a random sample of 800 dentists Respondents could answer the questions in writing or online. The data was collected in the period from November 2019 to January 2020, during which two reminders were sent.

Personalized Medicine Workflow in Post-Traumatic Orbital Reconstruction.

Restoration of the orbit is the first and most predictable step in the surgical treatment of orbital fractures. Orbital reconstruction is keyhole surgery performed in a confined space. A technology-supported workflow called computer-assisted surgery (CAS) has become the standard for complex orbital traumatology in many hospitals.

Financial, psychological, or cultural reasons for extracting healthy or restorable teeth.

Background: The purpose of this study was to determine how often dental patients request extraction for nondental reasons and how dentists handle such requests.

Methods: The authors conducted a survey among 800 Dutch dentists from November 17, 2019, through January 5, 2020. The questionnaire contained 17 items, including a hypothetical case vingette.

Surgical treatment of fractures of the zygomaticomaxillary complex: effect of fixation on repositioning and stability. A systematic review.

Management of zygomaticomaxillary complex (ZMC) fractures can be challenging. Consequently, there is a difference in treatment amongst clinicians. In the literature it remains unclear if the number of fixation points affects the quality of the anatomical reduction, stability through time, and potential complications.

Technical Note on Three- and Four-Wall Orbital Reconstructions With Patient-Specific Implants.

Orbital reconstruction is one of the most complex procedures in maxillofacial surgery. It becomes even more complex when all references to the original anatomy are lost. The purpose of this article is to provide an overview of techniques for complex three- and four-wall orbital reconstructions.

Reasons for Tooth Removal in Adults: A Systematic Review.

Objective: Most tooth extractions are performed for dental reasons, but there are also nondental and nonmedical reasons for extractions; these include psychological, financial, religious, and cultural reasons as well as simply granting a patient's request. This systematic review was performed to examine the proportion and range of indications associated with tooth removal in context of dental, nondental, and medical reasons.

Methods: A search conducted using PubMed, Embase, and APA PsycINFO identified 6038 studies.

Minimally Invasive Treatment With a Patient Specific Implant in Reconstruction of Isolated Anterior Wall Fracture of the Frontal Sinus.

Isolated fractures of the anterior wall of the frontal sinus are most often treated through a coronal approach. Although the coronal approach is a relatively easy procedure, the size of the incision is causing more problems related to patient morbidity and recovery time than smaller approaches. A novel, minimal invasive procedure for reconstruction of the anterior wall fracture of the frontal sinus is presented in this article.

A nonsurgical approach with repeated orthoptic evaluation is justified for most blow-out fractures.

Objective: This study presents the results of an updated clinical protocol for orbital blow-out fractures, with a special emphasis on nonsurgical treatment and orthoptic evaluation of functional improvement.

Methods: A two-centre multidisciplinary prospective cohort study was designed to monitor the results of a clinical protocol by assessing ductions, diplopia, globe position, and fracture size. Patients underwent clinical assessment and orthoptic evaluation at first presentation and then at 2 weeks and 3/6/12 months after nonsurgical or surgical treatment.

Is masticatory performance affected after a unilateral condylar fracture? A cross-sectional study.

Background: Mandibular fractures, especially condylar fractures, are one of the most common facial fractures. Trauma to this region could possibly compromise masticatory performance, which is a vital function for humans.

Objective: To objectively determine masticatory performance (Mixing Ability Test; MAT) in patients treated for a unilateral condylar fracture, thereby comparing patients in open and closed treatment groups, and assessing whether there is a positive relationship between this performance and subjective mandibular function (Mandibular Functional Impairment Questionnaire; MFIQ).

The advantages of advanced computer-assisted diagnostics and three-dimensional preoperative planning on implant position in orbital reconstruction.

Objective: Advanced three-dimensional (3D) diagnostics and preoperative planning are the first steps in computer-assisted surgery (CAS). They are an integral part of the workflow, and allow the surgeon to adequately assess the fracture and to perform virtual surgery to find the optimal implant position. The goal of this study was to evaluate the accuracy and predictability of 3D diagnostics and preoperative virtual planning without intraoperative navigation in orbital reconstruction.

Should Virtual Mirroring Be Used in the Preoperative Planning of an Orbital Reconstruction?

Purpose: Mirroring has been used as a diagnostic tool in orbital wall fractures for many years, but limited research is available proving the assumed symmetry of orbits. The purpose of this study was to evaluate volume and contour differences between orbital cavities in healthy humans.

Materials And Methods: In this cross-sectional study, the left and right orbital cavities of a consecutive sample of patients' computed tomograms were measured.
