Sleep disturbance and dysregulation of circadian clock machinery in sudden sensorineural hearing loss.

Background: The cochlea contains a robust biological clock associated with auditory function, exhibiting diurnal sensitivity to noise or ototoxicity.

Objectives: We examined the relationship between disrupted circadian rhythm and altered expression of circadian clock genes in patients with sudden sensorineural hearing loss (SSNHL) and explored whether the circadian clock genes serve as prognostic biomarkers.

Material And Methods: Twelve patients with SSNHL were enrolled study group.

Consumer-grade sleep trackers are still not up to par compared to polysomnography.

Purpose: Although polysomnography (PSG) is the gold standard for monitoring sleep, it has many limitations. We aimed to prospectively determine the validity of wearable sleep-tracking devices and smartphone applications by comparing the data to that of PSGs.

Methods: Patients who underwent one night of attended PSG at a single institution from January, 2015 to July 2019 were recruited.
