Ethmoidal silent sinus syndrome after nasal swab test.

This study reported the case of a healthy male in his 40s who presented with a 3-month history of frontal headache and post-nasal drip, which did not improve with oral antibiotics. One month prior to the onset of the symptoms, he underwent a nasopharyngeal swab testing for SARS-CoV-2 (which yielded a negative result) for a history of malaise and cough. The patient claimed that the swab insertion into the nasal cavity was particularly painful on the left side.

Postoperative CT findings of orthognathic surgery and its complications: A guide for radiologists.

Orthognathic surgery is the standard procedure to correct congenital, developmental, or acquired dentofacial deformities. The maxillomandibular relationship corrected by orthognathic surgery can improve facial esthetics, masticatory function, articulation, and breathing. The most common types of osteotomies include the combination of Le Fort I osteotomy, bilateral sagittal split mandibular ramus osteotomy, and genioplasty.

Sinus computed tomography findings in patients with COVID-19.

Objective: To analyze computed tomography scans of paranasal sinuses of a series of patients with coronavirus disease 2019, and correlate the findings with the disease.

Methods: Computed tomography scans of 95 adult patients who underwent a polymerase chain reaction test for severe acute respiratory syndrome coronavirus 2 were analyzed. Clinical data were obtained from patients' records and telephone calls.

Fighting the invisible enemy: providing support and structure to radiology resident during the COVID-19 pandemic.

The objective of this article is to share the strategy we used in order to restructure the radiology and diagnostic imaging department of a referral institution during the coronavirus disease 2019 pandemic, on the basis of the current recommendations. It is essential to integrate the work of supervisors, preceptors, and residents, maintaining communication and sharing decisions, with mutual support, as well as to determine the best strategy to be adopted in this scenario of uncertainty and constant change, while also ensuring adequate emotional support for all parties.

Endolymphatic hydrops evaluation on MRI: Practical considerations.

Four-hour delayed three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) sequence after intravenous gadolinium-based contrast agent administration is an optimal magnetic resonance imaging technique to evaluate endolymphatic hydrops in patients with known or suspected Ménière's disease. Nonenhanced endolymphatic space surrounded by enhanced perilymphatic space is evaluated in the cochlea and vestibule separately. In cochlear hydrops, the scala media is enlarged, potentially obliterating the scala vestibuli.

The role of magnetic resonance imaging in Ménière disease: the current state of endolymphatic hydrops evaluation.

Technical advances in magnetic resonance imaging have allowed to accurately detect and grade endolymphatic space distension in Ménière disease; this was only possible in post-mortem histological studies until a few years ago. Magnetic resonance imaging rules out other causes of vertigo and hearing loss, and is able to evaluate the cochlear and vestibular compartments of the endolymphatic space using a dedicated protocol.

Characteristics related to TMJ arthralgia, visualized by magnetic resonance imaging (3.0 Tesla).

Patients: Six women, with ages ranging from 52 to 64 years old, clinically evaluated (Research Diagnostic Criteria for Temporomandibular Disorders) by a single examiner were submitted to MRI (3.0 T). They had only arthralgia diagnosis.

The correlation of research diagnostic criteria for temporomandibular disorders and magnetic resonance imaging: a study of diagnostic accuracy.

Objective: The aim of this study was to evaluate the performance of research diagnostic criteria for temporomandibular disorders (RDC/TMD) as a diagnostic test for temporomandibular joint problems using magnetic resonance imaging (MRI) as the gold standard.

Study Design: Sixty-seven women were assessed with RDC/TMD (2 examiners) and underwent MRI examination (3.0 T).
