The objective of this review is to evaluate, on the basis of the available literature, if anterior open bite (AOB) can be successfully treated with the intrusion of molar teeth using skeletal anchorage in non-growing patients and adults and if this treatment modality provides comparable results to those obtained by orthognathic surgery procedures. Methods: A systematic review of published data in major databases from 2000 to 2021 was performed. Results: In total, 92 articles were included in title and abstract screening, and only 16 articles (11 concerning AOB correction by molar intrusion with skeletal anchorage, and five considering AOB treatment by orthognathic surgical intervention) qualified for thorough data extraction and analysis. Conclusions: On the basis of this review, it seems to be possible to obtain successful results for AOB treatment in non-growing patients and adults by means of the intrusion of molar teeth with skeletal anchorage. However, due to the different methods of assessing treatment outcomes used by different authors, it is not possible to state conclusively whether the treatment of AOB by means of molar intrusion with skeletal anchorage provides long-term results that are comparable to orthognathic surgery procedures.

ABSTRACT Adult patients with anterior open bite and hyperdivergent retrognathic phenotype demand complex treatments, as premolar extractions, molar intrusion or orthognathic surgery. In the present clinical case, a young adult patient without significant growth, with Class I and anterior open bite, was treated with four premolar extractions. The therapeutic result shows good intercuspation, good facial esthetic, good function balance, and stability in a two-year post-fixed treatment follow-up.

<b><i>Background:</i></b> Relationships between malocclusion and orofacial myofunctional disorders (OMD), as well as malocclusions and articulation disorders (AD) have been described, though the exact relationships remain unclear. Given the high prevalence of these disorders in children, more clarity is needed. <b><i>Summary:</i></b> The purpose of this study was to determine the association between OMD (specifically, bruxism, deviate swallowing, caudal resting tongue posture, and biting habits), AD, and malocclusions in children and adolescents aged between 3 and 18 years. To conduct a systematic review, 4 databases were searched (MEDLINE, Embase, Web of Science, and Scopus). The identified articles were screened for the eligibility criteria. Data were extracted from the selected articles and quality assessment was performed using the tool of Munn et al. [Int J Health Policy Manag. 2014;3:123–81] in consensus. Using the search strategy, the authors identified 2,652 articles after the removal of duplicates. After reviewing the eligibility criteria, 17 articles were included in this study. One of the included articles was deemed to have an unclear risk of bias, whereas all other articles were considered to have a low risk of bias. The articles showed a relationship between anterior open bite and apico-alveolar articulatory distortions, as well as between anterior open bite and deviate swallowing. For the biting habits, bruxism, and low tongue position no clear conclusions could be drawn. <b><i>Key Messages:</i></b> The current review suggests a link between specific types of malocclusion and OMD and AD. However, more high-quality evidence (level 1 and level 2, Oxford Levels of Evidence) is needed to clarify the cooccurrence of other OMD, AD, and malocclusions.

Condylar resorption (CR) can be categorized into functional and dysfunctional remodelling of the temporomandibular joint (TMJ). The literature describes dysfunctional remodelling of the TMJ as idiopathic condylar resorption (ICR). Idiopathic condylar resorption (ICR) is a well-documented but poorly understood pathological entity that can occur spontaneously or post-orthognathic surgery. It predominantly affects young women, with other risk factors including Class 2 malocclusion with steep mandibular plane angles. It is distinguished by a decreased condylar head volume and ramus height, progressive mandibular retrusion and an anterior open bite. Its aetiology can be categorized into surgical and non-surgical risk factors. These include hormones, systemic disease, trauma, mechanical load and surgical risk factors, such as magnitude and direction of mandibular movement, type of surgical fixation and length of post-operative maxilla-mandibular fixation. ICR is a diagnosis of exclusion, and identified by a combination of clinical, radiographic and haematological findings. Multiple treatment options have been described in the literature, including medical management, orthodontics, orthognathic surgery, TMJ surgery, TMJ and orthognathic surgery combined, and total joint prosthesis reconstruction. Further research is required to better understand the aetiology of ICR and more long-term, controlled, multicentre clinical studies are needed to evaluate the outcomes of surgical and non-surgical management of CR patients. CPD/Clinical Relevance: Idiopathic condylar resorption has many presentations and potential causes that can greatly impact the decisions and outcomes for orthodontic/orthognathic treatment.

Anterior Palatoplasty

Objective The aim of this study was to determine the general outcomes and surgical success rates of anterior palatoplasty (AP) in patients with obstructive sleep apnea (OSA). Data Sources A systematic review of the literature and meta-analysis of published data were performed by searching the Cochrane, SAGE, MEDLINE, and Google Scholar databases, from January 1, 2007, to March 27, 2017, using relevant keywords. Review Methods The search scanned for studies with patients who had undergone AP (with or without tonsillectomy) as a single-stage, single-level surgical intervention for treatment of OSA. Two independent reviewers (M.B. and O.K.) inspected titles and abstracts of the studies according to established criteria. The full texts were then reviewed to extract the clinical and polysomnographic data. The primary outcome was the surgical success rate, defined as a reduction in the apnea-hypopnea index (AHI) of 50% or greater and an AHI of less than 20 postoperatively. The PRISMA statement was followed. Results After systematic evaluation of potentially relevant articles, 14 studies were downloaded, and 6 studies, consisting of 170 patients, met the study criteria. A fixed effects model was used to analyze the data. The surgical success rate of AP was 60.6%. No serious complications were reported in the literature. Conclusion The results of the present meta-analysis support AP as a moderately effective surgical method for the treatment of OSA. Comparative and randomized controlled prospective studies showing long-term results, with pre- and postoperative data, should be conducted to demonstrate the exact outcomes and reliability of this surgical technique.

ABSTRACTObjective:The use of dantrolene in the treatment of hyperpyrexia related to MDMA (3,4-methylenedioxymethamphetamine) is controversial, with little data available to guide clinical decision-making. Although the treatment is recommended by several poison control centres, published data are primarily in the form of case reports and animal and in vitro experiments. We conducted a systematic review to investigate the published evidence regarding the safety and benefits of dantrolene for MDMA-related hyperpyrexia in humans.Data sources:A systematic search of Embase and MEDLINE was conducted from the earliest possible date to November 2008.Study selection:All human trials and case reports of MDMA-related hyperpyrexia were considered.Data extraction:Data were abstracted systematically and characteristics including use of dantrolene, adverse reactions attributed to dantrolene, peak temperature, complications from MDMA-related hyperpyrexia and survival were recorded.Data synthesis:Our search yielded 668 articles of which 53, reporting 71 cases of MDMA-induced hyperpyrexia, met our inclusion criteria. No clinical trials, randomized controlled trials, observational studies or meta-analyses were identified. Dantrolene was used in 26 cases. Patient characteristics were similar in the dantrolene and no dantrolene groups. The proportion of survivors was higher in the dantrolene group (21/26) than in the no dantrolene group (25/45). This difference was especially pronounced in those with extreme (≥ 42°C) and severe (≥ 40°C) fever, with a survival rate of 8 of 13 and 10 of 10, respectively, in the dantrolene group compared with 0 of 4 and 15 of 27 in the no dantrolene group. There were no reports of adverse events attributable to dantrolene with the exception of a possible association with an episode of transient hypoglycemia.Conclusion:Our systematic review suggests that dantrolene is safe for patients with MDMA-related hyperpyrexia. Dantrolene may also be associated with improved survival and reduced complications, especially in patients with extreme (≥ 42°C) or severe (≥ 40°C) hyperpyrexia, although this conclusion must be interpreted with caution given the risk of reporting or publication bias.
