Background: Dysbiosis of the bacterial and fungal microbiome has been increasingly implicated in the pathogenesis of chronic rhinosinusitis (CRS). This study explores the relationship between microbiome and mycobiome biodiversity and type 2 (T2) versus non-type 2 (NT2) inflammation.

Methods: Mucosal tissues from the ethmoid sinus were collected during endoscopic sinus (CRS) and skull base (controls) surgery between January 2020 and July 2021.

Patients and providers vary in how they describe common otolaryngology-related complaints. These differences can lead to miscommunication and frustration that may affect patient outcomes and satisfaction. The aim of this cross-sectional survey-based study was to explore the differences in migraine symptom selection by otolaryngology patients and clinicians.

Article Synopsis
  • Cystic fibrosis (CF) is often complicated by chronic rhinosinusitis (CRS), and while medical treatments exist, they may not always be effective for some patients, leading to the need for endoscopic sinus surgery.
  • This study aims to compare the outcomes of endoscopic sinus surgery versus continued medical treatment for individuals with CF and CRS, assessing various factors such as pulmonary function, quality of life, and depression.
  • The research is underway across nine CF centers in the U.S., and findings will contribute to guidelines for treating CF patients with CRS.

Article Synopsis
  • A 69-year-old diabetic woman developed acute invasive fungal rhinosinusitis (AIFRS) after a root canal and experienced worsening symptoms like facial pain and vision loss.
  • Initial evaluations missed the issue, but imaging later showed serious sinus complications, leading to surgery that confirmed the fungal infection, mucormycosis.
  • Treatment involved antifungal medications and surgery, highlighting that early detection and quick action are crucial for positive outcomes, especially in patients with underlying health issues like diabetes.

Background: Sociodemographic status (SDS) including race/ethnicity and socioeconomic status as approximated by education, income, and insurance status impact pulmonary disease in people with cystic fibrosis (PwCF). The relationship between SDS and chronic rhinosinusitis (CRS) remains understudied.

Methods: In a prospective, multi-institutional study, adult PwCF completed the 22-Question SinoNasal Outcome Test (SNOT-22), Smell Identification Test (SIT), Questionnaire of Olfactory Disorder Negative Statements (QOD-NS), and Cystic Fibrosis Questionnaire-Revised (CFQ-R).

Article Synopsis
  • - GPT-4 provided moderate quality information about sinusitis and its surgical options.
  • - The model produced much better responses specifically related to sinusitis treatment.
  • - Future research should aim to reduce bias and employ validated tools to evaluate the quality of GPT's answers.

Purpose: Sinonasal malignancies (SNMs) adversely impact patients' quality of life (QOL) and are frequently identified at an advanced stage. Because these tumors are rare, there are few studies that examine the specific QOL areas that are impacted. This knowledge would help improve the care of these patients.

Objective: To assess for differences in how patients and otolaryngologists define the term dizziness.

Methods: Between June 2020 and December 2022, otolaryngology clinicians and consecutive patients at 5 academic otolaryngology institutions across the United States were asked to define the term "dizziness" by completing a semantics-based questionnaire containing 20 common descriptors of the term within 5 symptom domains (imbalance-related, lightheadedness-related, motion-related, vision-related, and pain-related). The primary outcome was differences between patient and clinician perceptions of dizzy-related symptoms.

Objectives: To evaluate the clinical and prognostic behaviors of sinonasal papillomas.

Methods: Patients diagnosed with sinonasal papilloma were reviewed between 2001 and 2016 at a tertiary rhinology practice. Using pathology-specific electronic medical record software, patients diagnosed with sinonasal papilloma were identified.

Background: Chronic rhinosinusitis (CRS) is common in people with cystic fibrosis (PwCF). Rhinologic symptom prioritization and areas that influence CRS treatment choices, including pursuing endoscopic sinus surgery (ESS), remain understudied.

Methods: Adult PwCF + CRS were enrolled at eight centers into a prospective, observational study (2019-2023).

Objective This study aimed to evaluate patients with anterior cervical pain syndromes (ACPSs) by describing patient characteristics, therapeutic interventions, and response to treatments. Study Design This is a retrospective observational study. Methods Patients treated for diagnoses associated with ACPSs over a seven-year period in one laryngology practice at a tertiary care center were identified and evaluated via a review of clinical and surgical records.

Objective: To assess for differences of intended meaning in the description of congestion-related symptoms among otolaryngology patients and clinicians.

Materials And Methods: Between June 2020 and October 2022, a questionnaire consisting of 16 common descriptors of congestion-related symptoms within four domains (obstructive-related, pressure-related, mucus-related, and other symptoms) was completed by patients and otolaryngologists at five tertiary otolaryngology practices. The primary outcome was to assess differences in patient and clinician perceptions of congestion-related symptoms.

Although the incidence of postoperative acute and chronic rhinosinusitis in patients undergoing a sinus lift procedure is relatively high, a paucity of rhinology literature examines the management of and outcomes for this patient population. The objective of this study was to review the management and postoperative care of sinonasal complications and identify possible risk factors that should be considered prior to and following sinus augmentation. We identified sequential patients who had undergone a sinus lift procedure and were referred to the senior author (AK) at a tertiary rhinology practice for intractable sinonasal complications and reviewed their charts for demographic data, history of illness including prereferral treatment, examination findings, imaging results, treatment modalities, and culture results.

The Draf Ⅲ procedure involves the creation of a common frontal sinus cavity. The most common indication for the Draf Ⅲ procedure is chronic rhinosinusitis of the frontal sinuses despite the failure of more conservative interventions such as bilateral Draf Ⅱa procedures. Primary Draf Ⅲ may be indicated in patients with a high risk of failures such as those with severe polyposis and those with a frontal sinus opening less than 4 mm on computed tomography imaging.

Objective The American Academy of Otolaryngology-Head and Neck Surgery Foundation clinical practice guideline (CPG) proposes recommendations regarding sudden sensorineural hearing loss (SSNHL). SSNHL is managed by primary care, emergency medicine, and otolaryngology providers in the Department of Defense (DoD). However, their adherence to this CPG is unknown.
