Background: Lateral semicircular canal BPPV (LC-BPPV) is diagnosed by the head roll test (HRT), in which the head is rotated to move particles in the lateral canal, causing nystagmus. The body roll test (BRT) is performed in a rolling position with the body and head together, which has the advantage of safely rotating the head at the correct angle in both directions. This study aims to assess the diagnostic utility of the body roll test (BRT).

They occur predominantly in the middle ear, petrous apex, and orbital region, with rare occurrences in the labyrinth. Diagnosis of these lesions is challenging due to their imaging similarities with endolymphatic sac tumors, particularly in preoperative differentiation.
View Article and Find Full Text PDFObjectives: Persistent postural-perceptual dizziness (PPPD) is a chronic functional vestibular disorder for which the Bárány Society has established diagnostic criteria. This nationwide multicenter study aims to investigate the clinical features of individuals with definite PPPD and clinical variant PPPD who do not fully meet the diagnostic criteria, with a particular focus on visual exaggeration.
Methods: Between September 2020 and September 2021, a total of 76 individuals with definite PPPD and 109 individuals with clinical variant PPPD who did not meet all three exacerbating factors outlined in Criterion B were recruited from 18 medical centers in South Korea.
Purpose: The role of nasal problems such as allergic rhinitis in the development of obstructive sleep apnea (OSA) is controversial. The purpose of this study was to analyze the effects of house dust mite (HDM) allergen on sleep-related problems.
Methods: In a retrospective study patients were classified according to the house dust mite (HDM)-related specific immunoglobulin E (IgE) level into a low HDM-IgE group (group A) and a high HDM-IgE group (group B).

Objective: Benign paroxysmal positional vertigo (BPPV) is the most common cause of dizziness in the general population. BPPV is known to be closely related to the serum vitamin D level. This study aimed to examine the relationship between serum vitamin D levels and BPPV recurrence.

Objectives: Canalolithiasis of the posterior semicircular canal (PC) is the most common reason for benign paroxysmal positional vertigo (BPPV). If a patient is diagnosed with PC-BPPV through the Dix-Hallpike test, the modified Epley maneuver (mEpley) is used as the gold standard treatment. To reduce the discomfort of the standard mEpley, we proposed placing a pillow under the shoulders during this therapeutic maneuver.
View Article and Find Full Text PDFObjectives: We developed an edible taste film test that can be stored easily as a kit. This study was conducted to confirm the agreement between the results of the edible taste film kit test and the conventional taste solution test.
Design: Prospective, randomised, controlled trial.
Background: Dix-Hallpike (DH) test is sometimes done in a modified or reduced manner in a clinical setting. However, there has been no study that evaluated the reliability of this modified test.
Objectives: The purposes of this study were to determine whether the efficacy of a modified DH test, named the 'pillow under shoulders' test, was equivalent to the standard DH test and to assess the difference in patient discomfort between the two methods.
Objectives: We investigated the epidemiological and antibiotic resistance differences in methicillin-resistant Staphylococcus aureus (MRSA) infections in patients with otitis media with effusion (OME), acute otitis media (AOM), chronic suppurative otitis media (CSOM), and chronic cholesteatomatous otitis media (CCOM).
Materials And Methods: We conducted a retrospective study of patients with newly identified MRSA infections from January 2009 through January 2017. Overall, 3,522 patients from 10 tertiary referral hospitals were included in the study.

Nasopharyngeal angiofibroma is a rare head and neck tumor characterized by hypervascularity. With the development of various surgical devices and hemostatic agents, endoscopic endonasal surgery for nasopharyngeal angiofibroma, which is characterized by significant intraoperative bleeding, has become possible. We describe our experiences performing an effective endoscopic endonasal removal of a nasopharyngeal angiofibroma without embolization, using advanced devices and hemostatic agents.

Materials And Methods: Overall, 31 patients from four multicenter hospitals, who were diagnosed and surgically treated for CEAC in 2009-2014, were enrolled for this retrospective study. Medical records were reviewed to determine cancer stage according to the Pittsburgh classification.
Objectives: The aim of this multicenter registry study was to investigate the effectiveness of ventilation tube insertion and the microbiology of otitis media with effusion (OME) in children. This part I study was conducted to evaluate the microbiological profile of children with OME who needed ventilation tube insertion.
Methods: Patients <15 years old who were diagnosed as having OME and received ventilation tube insertion were prospectively enrolled in 16 tertiary hospitals from June 2014 to December 2016.
Changes over time in pathogens and their antibiotic sensitivity resulting from the recent overuse and misuse of antibiotics in otitis media (OM) have complicated treatment. This study evaluated changes over 5 years in principal pathogens and their antibiotic sensitivity in patients in Korea diagnosed with acute OM (AOM) and OM with effusion (OME). The study population consisted of 683 patients who visited the outpatient department of otorhinolaryngology in 7 tertiary hospitals in Korea between January 2010 and May 2015 and were diagnosed with acute AOM or OME.

However, little is known about the impact of the status of diabetes control on clinical features and treatment outcomes in patients with pulmonary TB (PTB). We conducted this study to evaluate whether the status of diabetes control influences clinical manifestations and treatment responses in PTB.

However, whether DHI reflects subjective symptoms during the acute phase has not been studied. This study aims to investigate the correlations of subjective and objective measurements to highlight parameters that reflect the severity of dizziness during the first week of acute unilateral vestibulopathy.

We evaluated the short-term efficacy of Epley, Semont, and sham maneuvers for resolving posterior canal benign paroxysmal positional vertigo (BPPV) in a prospective multicenter randomized double-blind controlled study. Subjects were randomly divided into three groups: Epley (36 patients), Semont (32 patients), and sham (Epley maneuver for the unaffected side, 31 patients). Out of 14 institutes which participated in this study, 5 institutes had previous experience of the Epley but not the Semont maneuver and the other 9 had previous experience of both maneuvers.

Background: Proteomic analysis by two-dimensional electrophoresis and matrix-assisted laser desorption and ionization time-of-flight mass spectrometry facilitates identification and characterization of specific proteins related to the pathogenesis of various diseases.
Methods: Proteins were extracted from two vestibular nerve specimens and two VS specimens and analyzed in parallel using two-dimensional electrophoresis.
Purpose: The objective of this study was to evaluate the effect of meteorological factors on the onset of idiopathic sudden sensorineural hearing loss (ISSHL).
Materials And Methods: Meteorological data from 2005 to 2011 were obtained from the web-based "Monthly Weather Reports of the Meteorological Administration" database. Patients with ISSHL who visited our hospital during this same period and presented the precise day on which hearing loss developed were included in this retrospective study.
Temporalis fascia has been used widely as a interposition graft for mucosal rotation flap in nasal septal perforation repair. However, the exact role of temporalis fascia in healing process has not yet been clarified. For the pedicle of rotation flap has been considered as a major vehicle for nutrition distribution, the role of temporalis fascia has been devaluated.
