Ultrasonography on the Early Postoperative Control of Severe Odontogenic Infections.

The management of odontogenic infections remains an important segment of the oral-maxillofacial surgical practice. The implementation of ultrasonography (US) imaging for the diagnosis of head and neck infections increases the possibility of visualizing the abscess collections in the deep neck spaces of lateral pharyngeal, masticator, and submandibular areas. The US imaging can detect the presence of fluid collections and edema, which may indicate local inflammation.

What Do We Know About COVID-19?: Maxillofacial Surgeons Survey.

Coronavírus disease 2019 (COVID-19) is a virus of mass dissemination, with an impact on international public health, leading to hospitalizations and death. The main symptoms of COVID-19 are fever, fatigue, dry cough; however, myalgia and dyspnea and the transmission routes include direct transmission by cough, sneeze, droplet inhalation, or contact transmission with the oral, nasal, or eye mucous membranes. The dental professionals are the main risk group to COVID-19 due to the transmission routes that are directly related to the dental practice.

New Device For Submental Endotracheal Intubation.

The submental intubation is a well-described technique as an alternative for the tracheostomy in the airway management in patients with contraindications for the nasotracheal and cannot remain in the orotracheal position due to the need to maintain the intermaxillary fixation. Residents and young oral and maxillofacial surgeons could have experienced some difficulty performing the technique first described by Altemir (1986). This report aims to describe a new device designed to facilitate and simplify the technique helping surgeons on the submental endotracheal intubation.

Background: The aim of the present study was to report the clinicopathologic, radiographic and immunohistochemical features of five South American cases of intraosseous xanthomas of the mandible and to compare them to those detected in a literature review.

Methods: Clinical data were collected from the records of three Oral and Maxillofacial Pathology services in South America and compared with those compiled from a literature review based on a search of three electronic databases (PubMed, Web of Science and Scopus).

Hemoglobin, red blood cells, hematocrit, and platelet were the primary outcome variables, operation time the secondary outcome, and the patients' age and weight the other variables.

Traumatic globe luxation associated with orbital fracture in a child: a case report and literature review.

Orbital fracture associated with traumatic globe luxation is rare, as it generally requires trauma with high energy for this to occur. The present case report focused on a child who had been hit by a motorcycle, leading to a globe luxation of the left eye and fractures of the superolateral orbital walls. The patient presented initial cosmetic and psychological benefits from the repositioning of the intact globe and the reduction of the orbital fractures.

Odontogenic fibroma (OF) is a rare benign odontogenic neoplasm that is most commonly found in the mandibular/premolar region of female patients in the second to fourth decades of life. Well-defined radiolucent lesions that may induce root resorption are normally observed. Rare variants of OF have been described in the prior literature, including references to: 1) giant cell lesions, 2) amyloid-like protein deposition, and 3) ossifying variants.

Complications from submental endotracheal intubation: a prospective study and literature review.

Submental endotracheal intubation, as compared to the use of tracheotomy, is an alternative for the surgical management of maxillofacial trauma, as described by Altemir FH (The submental route for endotracheal intubation: a new technique. J Maxillofac Surg 1986; 14: 64). Although the submental endotracheal intubation is a useful technique, a wide range of complications have been reported in the literature.

Low level laser effect after micro-marsupialization technique in treating ranulas and mucoceles: a case series report.

The aim of this preliminary study was to investigate the influence of low level laser therapy (LLLT) in alleviating pain caused by micro-marsupialization and the healing of oral ranulas and selected mucoceles.
