Introduction
Acoustic neuroma, also known as vestibular schwannoma, is a benign tumor originating from Schwann cells of the vestibulocochlear nerve. Its slow-growing nature often leads to symptoms such as hearing loss, tinnitus, and balance disturbances. Recent literature explores advancements in diagnostic techniques, treatment options, and outcomes for patients with this condition.
Diagnosis and Imaging Techniques
Advances in imaging, particularly MRI with gadolinium enhancement, have improved early detection rates. Imaging plays a vital role in differentiating vestibular schwannomas from other posterior fossa lesions, enabling timely treatment decisions (Lakshmipathy et al., 2024). Techniques like intralabyrinthine schwannoma detection are expanding, allowing better characterization of small tumors (Bae et al., 2024).
Treatment Approaches
Management strategies for vestibular schwannomas include observation, microsurgical resection, and radiosurgery. The choice depends on tumor size, patient age, symptom severity, and overall health. Microsurgical techniques have advanced to preserve hearing and facial nerve function. However, long-term quality-of-life outcomes suggest potential trade-offs in younger patients undergoing aggressive treatment (Shanker et al., 2024). Stereotactic radiosurgery is favored for small-to-medium tumors due to its minimally invasive nature and efficacy in controlling tumor growth (Szmulewicz et al., 2024). Emerging therapies, such as simultaneous cochlear implantation during tumor resection, are being explored for their dual benefits in tumor
management and auditory rehabilitation (Iannacone et al., 2024).
Quality of Life and Rehabilitation
Vestibular rehabilitation
Vestibular rehabilitation (VR) is a critical intervention for managing balance impairments and improving functional outcomes in patients with vestibular schwannoma (VS) or acoustic neuroma. Evidence from systematic reviews indicates that multimodal VR programs—encompassing gaze stabilization, habituation, and dynamic balance training—are more effective than singular modalities in addressing dizziness, postural instability, and vestibular dysfunction (Yap et al., 2024). While research supports the benefits of prehabilitation,
its impact on symptoms remains inconclusive. Studies also highlight the importance of early rehabilitation, which can enhance compensatory mechanisms, reduce long-term disabilities, and accelerate recovery. Despite the promising findings, the quality of evidence remains low due to heterogeneity, methodological limitations, and a lack of randomized controlled trials (Passier et al., 2012; Yap et al., 2024).
Case studies and emerging research further emphasize the role of physiotherapy in improving quality of life for patients post-treatment. For example, Bagga and Samal (2024) demonstrated significant improvements in postural stability and proprioception through customized rehabilitation programs involving gaze stabilization and balance exercises. Similarly, the Dynamic Gait Index (DGI) and Balance Error Scoring System (BESS) have been identified as reliable tools for monitoring progress and tailoring interventions. The incorporation of progressive balance training and multimodal approaches not only restores physical stability but also enhances confidence and participation in social and occupational activities (Szmulewicz et al., 2024; Zaidi et al., 2024).
The integration of VR into multidisciplinary care for VS is essential for optimizing outcomes. Physiotherapy-led interventions address both the physical and psychological impacts of vestibular dysfunction, offering targeted treatments that improve dynamic stability and reduce chronic disequilibrium. These approaches align with current clinical guidelines and underscore the need for further high-quality research to standardize protocols and enhance rehabilitation efficacy. As evidence-based practices continue to evolve, physiotherapists remain pivotal in guiding recovery and improving the overall quality of life for patients undergoing treatment for acoustic neuroma (Yap et al., 2024; Szmulewicz et al., 2024).
