Objective: To summarize adverse events and their root causes reported to the United States Food and Drug Administration (FDA) on Vibrant Soundbridge (VSB) hearing device (Med-El, Innsbruck, Austria), an active middle ear implant for patients with moderate to severe hearing loss.

Materials And Methods: The FDA's Manufacturer and User Facility Device Experience (MAUDE) database was queried for reports of VSB adverse events from January 1, 2012, to July 27, 2022.

Results: Six hundred sixty-three total medical device reports were identified, from which 913 adverse events were extracted.

Objectives: The aim of this study was to assess the prevalence of use of objective voice measurements (OVM), instrumentation, and factors that may impact OVM outcomes, such as setting and implementation to clarify current practice. Doing so should clarify the impact of OVM research on patient care.

Methods: A 12-question, one-time anonymous survey using the Research Electronic Data Capture tool was distributed during January 2023 to laryngologists in the United States identified through membership in The Voice Foundation (TVF) or previous participation in a TVF symposium.

Objective: Deglutition, speech production, and airway protection are extraordinarily complex, interrelated functions that are coordinated, in large part, by the motor and sensory innervation of CN X. Previous studies assessing the relationship between neurogenic voice disorders and dysphagia have focused on the risk of aspiration due to glottic insufficiency and the association of vocal fold hypomobility (VFH) with systemic neurologic disease. The purpose of this study was to investigate the relationship between VFH disorders and ineffective esophageal motility (IEM).

Objective: The primary objective of this study was to assess the prevalence of presbylarynx and its associated features in an elderly population representative of patients seen in a tertiary care laryngology practice. The secondary objective of this study was to compare laryngeal electromyography (LEMG) findings, coexisting VF conditions, medical history, surgical history, medication use, and other parameters between patients with and without presbylarynx.

Methods: Adult voice patients aged 60 years and older who underwent strobovideolaryngoscopy were included in the study.
