Brief summary
Previous studies have shown that vertigo is the symptoms that mostly affect quality of life in patients with vestibular schwannoma. There is still limited knowledge as to why some patients with this disorder develop vertigo, while others with the same diagnosis do not. The purpose of this study is to measure symptom-related quality of life and to relate this to objective disease characteristics at baseline.
Detailed description
This is a longitudinal observational study with data collected at baseline and after treatment. Variables collected at baseline include age, sex, tumor size, location, type (cystic/solid), tumor side, symptom variables including Dizziness Handicap Inventory, Vertigo Symptom Scale Short Form, Haukeland Dizziness Questionnaire, Visual analog scale, Hospital Anxiety and Depression Scale, RAND-12, dynamic posturography, video-based head impulse test, bithermal caloric tests, ocular and cervical vestibular evoked myogenic potentials. Follow-up data after 1 year are the same patient-reported outcomes as at baseline.
