Purpose: Safety and efficacy of SENS-401, a serotonin type 3 (5-HT) receptor antagonist and calcineurin inhibitor, in patients with acute sudden sensorineural hearing loss (SSNHL).

Methods: Multicentre randomized, double blind, placebo-controlled trial enrolled adult subjects with sudden sensorineural hearing loss (SSNHL) or unilateral/bilateral acute acoustic trauma leading to SSNHL within 96 h of disease onset. Subjects were randomly assigned to one of the three oral dose groups: 29 mg, 43.

Purpose: To explore the efficacy of diagnostic tests in accurately reclassifying patients initially diagnosed with probable Meniere's disease (MD) into either definite or non-MD categories.

Materials And Methods: A retrospective cohort study was conducted at a neurotology clinic between 1/2016 and 5/2022. Patients underwent a battery of tests, from which sensitivity, specificity, positive and negative predictive values, as well as positive and negative likelihood ratios, were calculated.

Introduction: Acute mastoiditis (AM) can rapidly become life-threatening with various intracranial complications. The standard care includes antibiotics, mastoidectomy, and drainage. Reports show varying preferences for conservative and surgical treatments, with a more conservative approach gaining popularity.

Introduction: The acoustic reflex is the active response of the middle ear to loud sounds, altering the mechanical transfer function of the acoustic energy into the inner ear. Our goal was to observe the effect of the acoustic reflex on the tympanic membrane by identifying a significant nonlinear increase in membrane oscillations.

Methods: By using interferometric spectrally encoded endoscopy, we record the membrane oscillations over time in response to a loud, 200-ms-long acoustic stimulus.

Objectives: The purpose of this study was to assess the effectiveness and safety of xylitol nasal spray as a prophylactic treatment for children with recurrent acute otitis media (AOM).

Methods: This is a prospective pilot study of children aged 1-4 years, diagnosed with recurrent AOM (at least three episodes in the three months before recruitment) between December 1, 2019 and January 31, 2023. Children were treated with nasal xylitol spray 2-3 times daily for 3 months.

Introduction: Otosclerosis is the primary cause of conductive hearing loss with normal otoscopy. As the condition worsens, certain patients may develop a sensorineural component. Patients with successful surgeries may still need hearing aids, which creates a dilemma for health professionals as there are insufficient data to make informed decisions.

The wide frequency range of the human hearing could be narrowed by various pathologies in the middle ear and in the tympanic membrane that lead to conductive hearing loss. Diagnosing such hearing problems is challenging, however, often relying on subjective hearing tests supported by functional tympanometry. Here we present a method for in vivo 2D mapping of the impulse response of the tympanic membrane, and demonstrate its potential on a healthy human volunteer.

Objectives: To assess the efficacy of avoiding mastoid pressure dressing (MPD) on children as a means of preventing discomfort and post-operative pain.

Design: A retrospective controlled study.

Setting: All operations were carried out by experienced surgeons using standard techniques, whose custom, not the gravity of any individual case, dictated the use of MPD.

Functional imaging of the human ear is an extremely challenging task because of its minute anatomic structures and nanometer-scale motion in response to sound. Here, we demonstrate noninvasive functional imaging of the human tympanic membrane under various acoustic excitations, and identify unique vibration patterns that vary between human subjects. By combining spectrally encoded imaging with phase-sensitive spectral-domain interferometry, our system attains high-resolution functional imaging of the two-dimensional membrane surface, within a fraction of a second, through a handheld imaging probe.

Objective And Intervention: To compare the efficacy of the inlay, composite chondroperichondrial clip (triple-C) tympanoplasty with conventional underlay cartilage island tympanoplasty, and to evaluate its efficacy in treating large, marginal perforations.

Study Design: The study involved 183 patients that were selected from a retrospective chart review of tympanoplasties performed at our center from March 2016 to June 2018.

Setting: A tertiary referral center hospital.
