Summary
Postural stability after vestibular schwannoma surgery is affected by tumor size and surgical approach. Vestibular rehabilitation improves stability by enhancing proprioception.
Area of Science:
- Neurosurgery
- Audiology
- Neurology
Background:
- Vestibular schwannoma surgery can impact postural stability.
- Understanding recovery patterns is crucial for patient management.
Purpose of the Study:
- To analyze factors influencing postural stability and recovery post-vestibular schwannoma surgery.
- To identify predictors of good and poor outcomes.
Main Methods:
- Retrospective analysis of 177 patients and prospective study of 44 patients.
- Measurement of body sway velocity under visual and nonvisual conditions.
- Logistic regression analysis to identify predictive factors.
Main Results:
- Preoperative postural instability was present in some patients.
- Abnormal sway velocity was common, correlating with tumor size and deficits.
- Postoperative sway velocity increased and did not fully recover within a year.
- Translabyrinthine approach, rehabilitation, age, and facial nerve function predicted good stability.
- Retrosigmoid approach and depression were risk factors for gait difficulties.
- Vestibular rehabilitation enhanced proprioception and improved stability.
Conclusions:
- Postural stability recovery is complex and influenced by multiple factors.
- Surgical approach, patient age, and rehabilitation are key predictors of outcome.
- Vestibular rehabilitation is effective in improving postural control and stability.
