Airborne SARS-CoV-2 RNA excretion by patients with COVID-19 on different oxygen-delivery systems: a prospective observational study.

Background: Concerns persist regarding the risk of airborne SARS-CoV-2 transmission by patients with COVID-19 on various modalities of oxygen therapy, such as high-flow nasal cannula (HFNC).

Aim: We aimed to compare the presence of airborne RNA in air samples between groups of patients with COVID-19 on different oxygen-delivery systems. We also explored factors that were associated with SARS-CoV-2 RNA positivity in air samples.

Depth of invasion in early stage oral cavity squamous cell carcinoma: The optimal cut-off value for elective neck dissection.

Objectives: Depth of invasion (DOI) is the most important predictor for lymph node metastasis (LNM) in early stage (T1-T2) oral cancer. The aim of this study is to validate the cut-off value of 4 mm on which the decision to perform an Elective Neck Dissection (END) is made.

Materials And Methods: We performed a retrospective study in patients with pathologically proven early stage oral cavity squamous cell carcinoma (OCSCC) without clinical or radiological signs of LNM, who were treated between 2013 and 2018.

What Are the Characteristics of the Upper Airway in Patients With Craniofacial Microsomia?

Purpose: Obstructive sleep apnea (OSA) is a common problem in patients with craniofacial microsomia (CFM); however, the exact pathophysiology in patients with CFM remains unclear. The first aim of this study was to evaluate upper airway volume and morphology in patients with CFM. The second aim was to identify risk factors for the presence of OSA.

Iatrogenic trigeminal post-traumatic neuropathy: a retrospective two-year cohort study.

With the growing demand for dental work, trigeminal nerve injuries are increasingly common. This retrospective cohort study examined 53 cases of iatrogenic trigeminal nerve injury seen at the Department of Oral and Maxillofacial Surgery, University Hospitals of Leuven between 2013 and 2014 (0.6% among 8845 new patient visits).

Comparison of 3D Scanning 2D Photography for the Identification of Facial Soft-Tissue Landmarks.

Background: Three dimensional facial scanning is an innovation that provides opportunity for digital data acquisition, smile analysis and communication of treatment plan and outcome with patients.

Objectives: To assess the applicability of 3D facial scanning as compared to 2D clinical photography.

Materials & Methods: Sample consisted of thirty Caucasians aged between 25 and 50 years old, without any dentofacial deformities.

Obstructive sleep apnoea in craniofacial microsomia: analysis of 755 patients.

A retrospective cohort study was set up to analyse the prevalence and treatment of obstructive sleep apnoea (OSA) in relation to the severity of the deformity in patients with craniofacial microsomia (CFM). This study included a population of 755 patients with CFM from three craniofacial centres. Medical charts were reviewed for severity of the deformity, types of breathing difficulty, age at which breathing difficulty first presented, treatment for OSA, and treatment outcome.
