Mandibular traumas by gunshot. A systematic review with meta-analysis and algorithm of treatment.

The treatment of mandibular fractures by gunshot ranges from late conservative repair to more aggressive early repair in a single stage. Treatments that preserve bony architecture as much as possible should be used, minimising patient morbidity and the complexity of future surgeries. The purpose of this study was to use a systematic review to determine which method of treatment was most effective for mandibular fractures by gunshot. Searches were conducted on Medline via PubMed, Scopus, Central Cochrane, and Sigle via Open Grey up to August 2019. Four studies were eligible to this systematic review, considering the previously establish inclusion and exclusion criteria. A total of 211 patients were evaluated. The mandibular body was the region more fractured followed by the symphyseal/parasymphyseal region. The closed treatment with intermaxillary fixation (IMF) was the most used followed by open surgery with internal rigid fixation (IRF) and external fixator. Considering the total adverse effects, the meta-analysis showed no statistically significant difference between the IMF and IRF groups (p=0.840), but IMF showed five times less infection and IRF six times less malunion. The algorithm was delineated from the types of injuries by gunshot, proposing forms of treatment from initial stabilisation to functional rehabilitation with implant-supported prostheses. The treatment of mandibular fractures by gunshot remains a challenge for surgeons. There was a statistically significant prevalence of success in the IRF group, however this group was also associated with a higher index of infection than the IMF group. New studies with high methodological quality and larger numbers of participants are needed to offer more safety for surgeons who treat patients with mandibular fractures by gunshot.

Celulite orbital por rinossinusite maxilar, etmoidal e frontal em paciente adulto: relato de caso / Orbital cellulitis by maxillary, etmoidal and frontal rhinosinusitis in an adult patient: case report

A celulite orbital é uma complicação incomum após quadro de rinossinusite. O objetivo do presente trabalho é relatar um caso de um paciente do sexo masculino, adulto-jovem, 22 anos de idade, que compareceu ao serviço de emergência apresentando edema periorbitário direito, proptose, oftalmoplegia, cefaléia, obstrução nasal e febre. O diagnóstico foi realizado por uma equipe multidisciplinar. A tomografia computadorizada pré-operatória apresentou edema difuso em região periorbitária direita, velamento dos seios: maxilar, esfenoidal e frontal ipsilateral. O paciente foi internado para abordagem cirúrgica e antibioticoterapia. A celulite orbitária associada a rinossinusite é uma complicação rara, sendo comum em crianças, que necessita de um diagnóstico e abordagem multidisciplinar e precoce para evitar extensões cranianas...

Orbital cellulitis is an uncommon complication after rhinosinusitis. The aim of the present study is to report a case of a 22-year-old male patient, young, 22 years old, who attended the emergency department with right periorbital edema, proptosis, ophthalmoplegia, headache, nasal obstruction and fever. The diagnosis was made by a multidisciplinary team. Preoperative computed tomography showed diffuse edema in the right periorbital region, veiling of the sinuses: maxillary, sphenoidal and ipsilateral frontal. The patient was admitted for surgical approach and antibiotic therapy. Orbital cellulitis associated with rhinosinusitis is a rare complication, common in children, which requires a multidisciplinary and early diagnosis and approach to avoid cranial extensions... (AU)

Partial Glossectomy as an Adjunctive Method to Ortho-Surgical Treatment.

The macroglossia is a rare condition, congenital or acquired, characterized by hypertrophy of the lingual muscles that can cause both aesthetic and functional changes such as mandibular prognathism and malocclusion. Diagnosis is through clinical examination. Treatment consists of excision of part of the tongue and different surgical techniques have been described in the literature. The keyhole lingual resection technique has shown satisfactory results in reducing the volume and preservation of the neurovascular bundles of the tongue. This work aims to present a clinical report of true macroglossia associated with dental-skeletal discrepancies, submitted to partial glossectomy previously to orthognathic surgery.

Effects of mepivacaine 2% with epinephrine in the cardiovascular activity of patients undergoing third molar surgery: a prospective clinical study.

BACKGROUND: Cardiovascular effects of epinephrine, especially on blood pressure (BP) and heart rate (HR), have been well documented. When present in dental local anesthetic solutions, epinephrine concentration ranges from 5 to 20 µg/mL. Doses less than 200 µg are recommended to be clinically safe. OBJECTIVES: This study investigated the effects of the anesthetic solution of mepivacaine (2%) with epinephrine (10 µg/mL) in cardiovascular activity (HR and BP). METHODS: Twenty-six patients underwent outpatient surgery for the removal of 2 unilateral (group I, n = 15) or 4 (group II, n = 11) third molars in a single session, being injected 5.4 and 10.8 mL of anesthetic solution, equivalent to 54 and 108 µg of epinephrine, respectively. The cardiovascular activity was monitored by cardioscope during the experimental period of 2 hours. Heart rate and BP were measured at the intervals of 0, 5, 10, 15, 20, 30, 40, 60, 90, and 120 minutes after anesthetic injection. RESULTS: After application of 2-way analysis of variance test, comparison between groups was not statistically significant for HR (P = 0.1388), systolic BP (P = 0.0228), and diastolic BP (P = 0.9846). However, patients from group II presented significantly greater sway in HR (P < 0.0001), systolic BP (P = 0.0169), and diastolic BP (P < 0.0001) in the course of 2 hours. CONCLUSIONS: Blood pressure did not present significant alterations after a local injection of 54 or 108 µg of epinephrine during surgery to remove 2 or 4 third molars. Although without significance, HR was more elevated in the 108-µg dose of epinephrine during the removal of 4 third molars.
