How face masks influence the sinonasal quality of life during the COVID-19 pandemic.

Purpose: To study different mask types' impact on a sinonasal quality of life.

Methods: For this observational cross-sectional study, a web-based survey was distributed via social media forums. We used the validated Hebrew version of the Sinonasal Outcome Test-22 followed by a questionnaire developed specifically for the present study, focusing on the time of the COVID-19 pandemic (Mask Sinonasal Outcome Test), and questions regarding general health issues.

Effect of surgery, delivery device and head position on sinus irrigant penetration in a cadaver model.

Objective: The extent of surgery, the type of device used and head position may influence nasal irrigation. The aim of this study was to determine the effectiveness of topical irrigant delivery to the paranasal sinuses according to these factors.

Method: Four cadaveric heads underwent four stepwise endoscopic dissections.

Can Computed Tomography Findings Predict the Recurrence of Sinonasal Inverted Papilloma?

Objective: To evaluate the correlation between the ability to predict the attachment site of sinonasal inverted papilloma by computed tomography and the long-term surgical outcome.

Human Nasal Turbinate Tissues in Organ Culture as a Model for Human Cytomegalovirus Infection at the Mucosal Entry Site.

The initial events of viral infection at the primary mucosal entry site following horizontal person-to-person transmission have remained ill defined. Our limited understanding is further underscored by the absence of animal models in the case of human-restricted viruses, such as human cytomegalovirus (HCMV), a leading cause of congenital infection and a major pathogen in immunocompromised individuals. Here, we established a novel model of HCMV infection in native human nasal turbinate tissues.

No impact of nasal septoplasty on the outcome of endoscopic dacryocystorhinostomy.

Horizontal lateral lamella as a risk factor for iatrogenic cerebrospinal fluid leak. Clinical retrospective evaluation of 24 cases.

Background: Several authors highlighted the limitations of the Keros classification system in predicting intracranial entry risk. Recently, our group proposed a new classification system based on the angle formed between the lateral lamella of the cribriform plate (LLCP) and the continuation of an horizontal plane passing through the cribriform plate (Gera classification). The aim of this study was to analyze whether the risk of iatrogenic cerebrospinal fluid leak (CSF-L) was better predicted by Keros or Gera classification.

The significance of Computed Tomography in invasive paranasal mucormycosis.

Introduction: Early diagnosis of acute invasive fungal rhinosinusitis (AIFR) is crucial for patients prognosis and may reduce the extent of surgical debridement. Initial evaluation usually includes paranasal Computed Tomography (CT), with an emphasis on bony erosion which is considered a specific but insensitive radiologic sign. Most studies made no distinction between Aspergillus and Mucor species while addressing CT findings.
