A White Spot Around the Fissula Ante Fenestrum: A New Diagnostic Indicator for Otosclerosis.

: Since we started endoscopic stapes surgery, we have frequently noticed a white spot (WS) with a clear boundary on the bone surface around the fissula ante fenestrum (FAF) in otosclerosis cases. We investigated the significance of this surgical finding. : We enrolled 27 cases of otosclerosis and 28 control cases of conductive hearing loss due to pathologies other than otosclerosis, both operated on endoscopically at the University of Tokyo Hospital.

Velopharyngeal Insufficiency and Impaired Tongue Movement Indicate Neuromuscular Disorders: A 10-Year Statistical Study in a Single Tertiary Institution.

: This study aimed to determine the positive predictive value of our NMD Suspicion Criteria in the diagnosis of NMDs. Other clinical factors routinely examined in our voice and swallowing examinations were also investigated to see if they had a significant association with the diagnosis of NMDs. : This study retrospectively investigated the medical charts of patients who visited our Voice and Swallowing outpatient clinic between 2013 and 2022.

Multicenter randomized double-blind placebo-controlled crossover study of the effect of prolonged noisy galvanic vestibular stimulation on posture or gait in vestibulopathy.

Objective: This multicenter, randomized, double-blind, placebo-controlled, crossover trial aimed to evaluate whether prolonged noisy galvanic vestibular stimulation improves body balance in patients with vestibulopathy.

Materials And Methods: This trial was registered in the Japan Pharmaceutical Information Center Clinical Trials Information registry (jRCT1080224083). Subjects were 20- to 85-year-old patients who had been unsteady for more than one year and whose symptoms had persisted despite more than six months of rehabilitation.

The Effects of Circadian Rhythm on Lead-Induced Toxicity in the DBC1.2 Olfactory Dark Basal Cell Line.

Background/objectives: This study evaluated changes in circadian clock genes and mitochondrial function in a lead (Pb)-induced toxicity model of an olfactory epithelial cell line.

Methods: The DBC1.2 olfactory dark basal cell line was used.

Vestibular Function in Patients With Vestibular Neuritis Experiencing Prodromal Dizziness.

Introduction: It is unknown whether prodromal dizziness (PD) before an attack of vestibular neuritis (VN) has an association with peripheral vestibular lesions. The purpose of this study was to investigate whether the severity of vestibular dysfunction has an association with the presence of PD.

Methods: We reviewed the medical records of 88 consecutive unilateral VN patients with unilateral canal paresis in caloric testing.
