Evolution of Vestibular Function After Treatment of a Vestibular Schwannoma by Gamma-knife Radio-surgery

Study Purpose

The purpose of this study is to evaluate the vestibular effects of gamma-knife radiosurgery, as part of the treatment of vestibular schwannoma.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	Yes
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years - 90 Years
Gender	All

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06112509
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	N/A

Additional Details

Vestibular schwannoma is a benign tumor located on the vestibulocochlear nerve. It represents 6 to 8% of intracranial tumors, 80% of ponto-cerebral angle tumors and its frequency is 13 cases per million inhabitants per year. The main symptoms related to the development of vestibular schwannoma are unilateral deafness of perception, unilateral tinnitus, unilateral vestibular deficit vertigo, facial paralysis. Management is divided into 3 options: monitoring, surgery and gamma-knife radiosurgery. This study will focus on gamma-knife radiosurgery. The objective of this treatment is to stabilize the evolution of schwannoma. This study aims to describe the vestibular effects of radiosurgery.
