AI Article Synopsis
- This systematic review analyzed literature on the hearing outcomes of patients with vestibular schwannoma, using the Grading of Recommendations Assessment, Development and Evaluation system to evaluate the studies.
- Out of 217 studied papers, 15 were selected, encompassing data from 2,142 patients, focusing on hearing preservation based on the AAO-HNS classification system.
- Findings indicated that about 50% of patients with good hearing at diagnosis maintained their hearing after an average of 5 years, with a higher likelihood of preservation for those with normal discrimination scores at diagnosis.
Article Abstract
This is a systematic review of the literature on the spontaneous course of hearing in patients observed with a vestibular schwannoma. Included studies are appraised using the Grading of Recommendations Assessment, Development and Evaluation system. PubMed, Embase, Medline, Cochrane library, and CINAHL (Cumulative Index to Nursing and Allied Health Literature) were searched for literature on hearing in patients observed with a vestibular schwannoma. Of 217 evaluated papers, 15 were included, representing a total of 2,142 patients. Hearing according to the AAO-HNS (American Academy of Otorhinolaryngology- Head and Neck Surgery) classification system. Weighted average of the proportion of patients preserving good hearing (>70% discrimination score and pure tone audiometry [PTA] < 30dB) and serviceable hearing (>50% discrimination score and PTA < 50dB) was determined. Fifty percent of patients presenting with good hearing at diagnosis had preserved this after a mean of 5 years of observation, whereas serviceable hearing was preserved in 54%. Patients with normal discrimination at diagnosis preserve their hearing very well. Very few studies exist on long-term hearing preservation. After 5 years of observation, around half of patients will have preserved good or serviceable hearing. Patients with normal discrimination at diagnosis are more likely to preserve good hearing.

Comparing the Accuracy and Reliability of ABC/2 and Planimetry for Vestibular Schwannoma Volume Assessment.
Otol Neurotol
February 2025
Department of Radiology, Yale School of Medicine, New Haven, CT.
Background: Vestibular schwannoma (VS) is a common intracranial tumor that affects patients' quality of life. Reliable imaging techniques for tumor volume assessment are essential for guiding management decisions. The study aimed to compare the ABC/2 method to the gold standard planimetry method for volumetric assessment of VS.

Background: Changes in the connections between the cortical regions responsible for integrating balance are observed in individuals with MCI, however, studies that clarify the association of these changes and the risk of falling due to body imbalance are still rare. The present study aims to compare the posturography response of individuals diagnosed with MCI in relation to individuals in a control group without MCI.
Methods: This research project was approved by the local ethics committee.
Diverse phenotype of Ménière's disease associated with family history, thyroid disorder, migraine and associated disorders.

Objective: To better understand the clinical phenotype of Ménière's disease (MD), we examined family history, thyroid disorder, migraine, and associated disorders in complaints of people living with MD.
Method: We designed the study as a retrospective and examined data gathered from 912 participants with MD. Their data were originally collected by the Finnish Ménière Federation (FMF).
Vestibular Hypofunction in Patients with Presbycusis: A Cross-Sectional Study.
J Clin Med
December 2024
Department of Neurology, Medical Faculty, University Hospital Carl Gustav Carus, TUD Dresden University of Technology, 01307 Dresden, Germany.
Vestibular Hypofunction (VH) and hearing loss can affect quality of life and lead to disability, especially in the elderly. Studies investigating presbycusis and vestibular function in the aging population have been conducted separately, but few have examined the combination of both conditions in older patients, with inconsistent results that may be due to small sample sizes or heterogeneity in the methods used to assess vestibular function. We aimed to characterize the occurrence of VH in patients with presbycusis using the video head impulse test (vHIT), which is a specific and reliable assessment tool for VH.

Background: Pimozide is a conventional antipsychotic drug of the diphenylbutylpiperidine class, widely used for treating schizophrenia and delusional disorders and for managing motor and phonic tics in Tourette's syndrome. Pimozide is known to block dopaminergic D2 receptors and various types of voltage-gated ion channels. Among its side effects, dizziness and imbalance are the most frequently observed, which may imply an effect of the drug on the vestibular sensory receptors, the hair cells.
