Do otosclerosis and stapedotomy affect semicircular canal functions? Preliminary results of video head impulse test.

Background: Otosclerosis and stapedotomy have some effects on the vestibular system, but there are very limited data on their effects on semicircular canals (SCCs).

Objective: The aim of the study is to investigate if otosclerosis and stapedotomy have an effect on SCCs and video head impulse test (vHIT).

Material And Methods: This retrospective study included 11 otosclerosis patients who had undergone stapedotomy and 30 healthy participants.

Can Narrow Band Chirp Stimulus Shake the Throne of 500 Hz Tone Burst Stimulus for Cervical Vestibular Myogenic Potentials?

Background And Objectives: The aim of the study was to compare effects of tone-burst (TB) and narrow-band (NB) Claus Elberling (CE)-chirp stimuli on amplitude, latency and interaural asymmetry ratio (IAR) of cervical vestibular evoked myogenic potentials (cVEMP) in healthy individuals.

Subjects And Methods: The study included 50 healthy volunteers. cVEMP procedure was carried out using 500 Hz TB and NB-CE-chirp stimulus (360-720 Hz, up-chirp) in random order.

Does tympanic membrane perforation have a protective effect on the inner ear in blast-injured patients?

Background: Blast-induced hearing loss is an acoustic trauma commonly caused by high-energy explosions of improvised explosive devices, and the auditory system may be affected by blast damage. This study aims to evaluate the protective effect of tympanic membrane perforation (TMP) on the inner ear against blast injury.

Methods: In this study, 43 adult patients who had suffered blast injury were divided into three subgroups: intact tympanic membranes in both ears, unilateral TMP, and bilateral TMP.

Routine Vestibular Tests May Point Out Vestibular Subtype of Seasickness Only.

The vestibular system is important in the pathogenesis of seasickness. Our objective is to investigate whether routine vestibular tests detect seasickness. Included were 17 professional naval personnel (mean age of 29.

Differences in bone conduction ocular vestibular evoked myogenic potentials to 500 Hz narrow band chirp stimulus and 500 Hz tone burst.

Objective: This study aims to investigate the differences of N1 latency, P1 latency and N1P1 amplitude in response to bone conducted 500 Hz tone burst and narrowband CE chirp stimulus in ocular vestibular evoked myogenic potentials (oVEMPs).

Methods: Forty-two healthy volunteers were included in this prospective study. Subjects with abnormal otological examinations and otological diseases were excluded.

Normative Data of Ocular Vestibular Evoked Myogenic Potentials in Response to Chirp Stimulus.

Objectives: This study aims at comparing the tone-burst (TB) and narrow-band (NB) CE-chirp stimuli in terms of amplitude, latency, and interaural asymmetry ratio (IAR) in ocular vestibular evoked myogenic potentials (oVEMP).

Materials And Methods: In this prospective study, we enrolled 60 healthy subjects (27 men, 33 women) with a mean age of 25.83 (range, 18-48) years.

Recognizing Decompensated Meniere's Disease Using High Frequency Rotational Test.

Objectives: The purpose of this study is to investigate the effectiveness of the high-frequency rotational test for discrimination of patients with decompensated from those with compensated Meniere's disease.

Materials And Methods: Patients with unilateral Meniere's disease were divided into two groups (compensated and decompensated), based on the presence of clinically significant positional nystagmus as a determinant of the compensation status. All patients and subjects underwent pure tone audiometry, video nystagmography, and the vestibular autorotation test (VAT).
