Tuberculosis of the paranasal sinus is a rare disease caused by infection with Mycobacterium tuberculosis, the causative agent of pulmonary tuberculosis. Although the worldwide incidence of tuberculosis is declining, the diagnosis of primary paranasal tuberculosis remains challenging and cannot be ruled out in patients presenting with refractory chronic rhinosinusitis after adequate surgical and medical treatment. We experienced a case of paranasal tuberculosis with no evidence of previous tuberculosis infection.

Relatively little is known about the predisposing factors and pathogenesis of unilateral sphenoid sinus fungal balls (SSFBs) compared to maxillary sinus FBs. We investigated whether anatomical variations have clinical implications for the location of unilateral SSFBs.

Objective: Data on the global prevalence of chronic rhinosinusitis (CRS) is significantly varied and limited across countries and over time. Therefore, we aimed to conduct a comprehensive investigation into the global, regional, and national burden of CRS from the years 1980 to 2021, as well as identify those factors that influence levels of such burden.
Design: We conducted a systematic review and meta-analysis of general population-based observational studies focusing on CRS.
Facial nerve palsy directly impacts the quality of life, with patients with facial nerve palsy showing increased rates of depression and limitations in social activities. Although facial nerve palsy is not life-threatening, it can devastate the emotional and social lives of affected individuals. Hence, improving the prognosis of patients with this condition is of vital importance.

Methods: Adult male Sprague-Dawley rats underwent crushing or cutting injury of the unilateral facial nerve. Their whisker movement and blink reflex were examined.
Objectives: To assess the validity and reliability of the Korean version of the reflux symptom score (K-RSS).
Materials And Methods: The English version of the RSS was translated into Korean and completed by 77 people (44 and 33 people in the patient group and control group, respectively). They completed the K-RSS (K-RSS-1) and reflux symptom index (RSI) questionnaires and answered questions about age, sex, underlying disease, smoking history, and alcohol and coffee consumption.
Background: Endoplasmic reticulum (ER) stress is a cellular defense mechanism that occurs when ER function is impaired.
Objective: This study was designed to evaluate the expression of major mRNAs of ER stress in patients with otitis media with effusion (OME), chronic otitis media (COM), and COM with cholesteatoma (CholeOM).
Material And Methods: Specimens were collected during surgery from patients with OME, COM, and CholeOM, and the levels of ER stress mRNAs measured by real-time polymerase chain reaction.

Objectives: Following the increased use of antibiotics, the emergence of antibiotic-resistant species in pediatric patients with otitis media has become a problem in recent years. The aim of this study was to investigate change in bacterial species, antibiotic resistance, and detection rate of highly pathogenic species, such as Methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa according to the number of repeated ventilation tube insertion (VTI) procedures in pediatric patients diagnosed with otitis media with effusion (OME).
Materials & Methods: From May 2010 to June 2018, 158 patients under 17 years of age who were admitted to the outpatient clinic of Kyung Hee Medical Center and diagnosed as OME and underwent unilateral or bilateral VTI were included in this study.
