RESUMEN
PURPOSE: The aim of the present study was to determine the methodological quality of systematic reviews that evaluated the effectiveness of pentoxifylline and tocopherol (PENTO) in the treatment of osteoradionecrosis of the jaw (ORNJ) and medication-related osteonecrosis of the jaw (MRONJ). METHODS: Searches were performed in Databases including PubMed, Scopus, LILACS, DARE, Cochrane Library, and SIGLE through OpenGrey until March 2024, were evaluated by two independent reviewers to answer the following question: Is the use of PENTO protocol effective in the treatment of ORNJ or for the treatment of MRONJ? RESULTS: A total of 256 articles were initially identified; however, following the use of appropriate inclusion and exclusion criteria, five systematic reviews were identified for detailed analysis. The final study sample comprised 588 patients: 397 patients with ORN and 197 patients with MRONJ who were treated with PENTO. The total recovery of individuals who used the PENTO protocol was 62,2 % for ORN and 100 % for MRONJ, with a follow-up period of 1 month to 10 years. The methodological quality of the studies was assessed using the AMSTAR 2 tool, in which four were of low quality and 1 moderate quality. CONCLUSION: The treatment of ORN and MRONJ with pentoxifylline and tocopherol has shown good results in the studies presented, with a partial or total reduction in bone exposure. However, the low quality of the relevant reports highlights the need for primary and secondary studies with better methodological rigor to reduce bias and provide reassurance for this treatment option.
RESUMEN
This study aimed to evaluate the scientific evidence on the effect of preemptive drug coadministration (PDC) for relieving inflammatory events (pain, swelling, and trismus) in mandibular third molar surgery. A PROSPERO-registered systematic review (CRD42022314546) was conducted according to the PRISMA guide. The searches were carried out in six primary databases and the gray literature. Studies not written in languages with the Latin alphabet (Roman) were excluded. Potential randomized controlled trials (RCTs) were screened for eligibility. Cochrane's Risk of Bias-2.0 (RoB) tool was assessed. A synthesis without meta-analysis (SWiM) based on a vote counting and an effect direction plot. Nine studies (low RoB) fulfilled the eligibility criteria and were included for data analysis, with a total of 484 patients. PDC mostly involved corticosteroids (Cort) and non-steroidal anti-inflammatory drugs (NSAIDs). PDC of Cort and other drugs mainly reduced pain scores (6 and 12 h postoperatively) and swelling (48 h postoperatively). PDC of NSAIDs and other drugs mainly reduced pain scores at 6, 8, and 24 h follow-up; swelling and trismus intensity ameliorated at 48 h postoperatively. The most frequently prescribed rescue medication was paracetamol, dipyrone, and paracetamol plus codeine. Results from individual studies have shown reduced consumption of ingested rescue analgesics. In summary, the available evidence from clinical trials included in this SWiM suggests that PDC may provide benefits in reducing the severity of inflammatory outcomes related to mandibular third molar surgery, especially the pain scores in the first hours after surgery, and the rescue analgesic consumption during the postoperative period.

INTRODUCTION: Defects in the lower border of the mandible may represent an aesthetic problem after mandibular advancement in orthognathic surgery. The use of bone grafts has been reported in the literature as a possibility to reduce these defects in the postoperative period. OBJECTIVE: The objective of this systematic review is to answer the following research question: Is it necessary to use bone grafts to prevent defects at the lower border of the mandible after mandibular advancement? METHODS: The literature search was conducted on MEDLINE via PubMed, Scopus, Central Cochrane, Embase, LILACS, and Sigle via Open Gray up until December 2020. Five studies were eligible for this systematic review, considering the previously established inclusion and exclusion criteria. RESULTS: 1340 mandibular osteotomies were evaluated, with a mean advance of 8 mm, being 510 with bone graft (42 defects), 528 without graft (329 defects), and 302 with an alternative technique (32 defects). Regarding the type of bone graft used, three articles used xenogenous or biomaterial grafts and two allogenous bone grafts. The results of the meta-analysis showed a reduction in the presence of defects in the bone graft group: OR 0.04, 95% CI = 0.01, 0.19; p = 0.0005, (I2 = 87%; p < 0.0001). CONCLUSION: The use of bone grafts seems promising in reducing defects in the lower border of the mandible after mandibular advancement. New controlled prospective studies with a larger number of participants are needed to ensure the effectiveness of this procedure.

Masseter hypertrophy is an uncommon condition, characterized by an increase in the volume of the masseter region, with the patient presenting functional and aesthetic complaints. Several therapeutic modalities have been suggested for this condition, however, a surgical approach usually presents consistent results in more complex cases. The objective of this article is to report a clinical case of masseter hypertrophy associated with class IV of Kin, treated through partial removal of the masseter muscle, bichectomy and genioplasty. Surgery was performed under general anesthesia in a hospital setting. The planning was previously carried out through prototyped models and radiographs to remove the excess bone shown in the mandibular angle region. Surgical treatment of masseter hypertrophy is effective and long-lasting in severe cases. Additional surgical procedures must be performed in order to provide the best possible result according to the facial deformity found.
RESUMEN
Hemangiomas are benign vascular lesions characterized by endothelial vascular proliferation and may demonstrate aggressive clinical features. Intraosseous hemangiomas are uncommon and the maxillary location rare, with few cases described in the literature. The treatment of these lesions varies, however they have a better prognosis when a surgical treatment through resection is performed. The aim of this study is to report a case of right maxillary cavernous intraosseous hemangioma treated by surgical resection with previous embolization. The diagnosis was made through incisional biopsy and immunohistochemical examination. An aggressive lesion profile was observed through the Ki67 marker. During surgery, a temporary ipsilateral external carotid artery ligation was performed to minimize possible bleeding. Weber-Fergson surgical access was performed and total surgical resection through hemi-maxillectomy. The patient is stable after 30 months of follow-up without relapses. In suspected cases of intraosseous hemangiomas, accurate diagnosis and total surgical resection of the lesion is essential. The use of therapeutic mammoths that minimize sagging during and after the procedure such as embolization and arteriography should always be performed.

Oral Mucositis is a frequent and debilitating inflammatory complication in patients with head and neck malignancies and may lead to unplanned treatment interruptions due to intense pain and dysphagia. This systematic review with meta-analysis was performed to determine the effectiveness of low-level laser therapy in preventing oral mucositis in this context. The following databases were searched through September 2018, with last search performed on May 2019, for clinical trials: MEDLINE via PubMed, Cochrane Central, Scopus, Lilacs, ISI Web of Science and SIGLE via Open Grey. From 14,525 records, 4 studies were included in the review and 3 studies were included in meta-analysis. Data from 500 patients (mean age of 53.595 and 54.14 for intervention and control groups, respectively) were analysed. Meta-analysis showed that laser therapy prevents oral mucositis incidence in 28% and 23% of cases during the third and fourth follow-up week, respectively, in comparison to a placebo-treated control group. There was no statistically significant difference the prevention of pain; dysphagia and quality of life were not analysed due to missing. Laser therapy was effective in preventing oral mucositis from the 15th to the 45th days of chemoradiotherapy. However, new primary studies with low risk of bias are needed so a higher scientific evidence can be obtained.

INTRODUCTION: Facial and mandibular aggression with gunshot wound (GSW) is highly complex and represents a challenge for the assistant surgical team because in addition to the inherent lethal potential, they have the capacity for destruction and mutilation caused by the high kinetic energy conferred to the firearm projectile. Among these lesions, comminutive mandibular fractures are difficult to treat because the anatomical planes are distorted, soft tissues are in severe disarrangement, and bone fragments are without periosteum, which, if opted for an open treatment, with internal fixation, favor the development of soft tissue infections, osteomyelitis, and suture dehiscence. The treatment of comminuted mandibular fractures with external fixator, widely used during the Second World War, represents a modality of treatment that minimizes the risks of failure, since it allows stabilization of the fractured mandible with minimal aggression to the soft tissues. OBJECTIVES: The objective of this study is to report three cases where surgical procedures were performed to treat comminuted mandible fractures with the adaptation of specific external orthopedic fixator for wrist.
