Acoustic Neuroma Treatment: Surgery, Radiotherapy, and Post-Operative Rehabilitation for Schwannoma Management

The acoustic neuroma, also known as vestibular schwannoma, is a benign tumor that originates from the vestibular nerve. Although its growth is slow, it can cause significant symptoms such as hearing loss, vertigo, and tinnitus. The treatment for acoustic neuroma focuses on three main approaches: surgery, radiotherapy, and post-operative rehabilitation. Each of these methods has specific indications and is chosen based on factors such as tumor size, patient age, and the presence of comorbidities.
Treatment Options: Surgery and Radiotherapy
Surgery is a common option for treating acoustic neuroma, especially in large tumors or when significant symptoms are present. Surgical resection can be performed through different approaches, such as retrosigmoid or translabyrinthine, depending on the tumor's location and size. However, surgery can lead to complete hearing loss on the affected side, highlighting the importance of considering post-operative hearing rehabilitation.
Radiotherapy, particularly stereotactic radiosurgery, is a less invasive alternative that may be suitable for smaller tumors or in patients who are not good candidates for surgery. This approach aims to halt tumor growth while preserving hearing function as much as possible. However, long-term hearing preservation remains a challenge, and only a percentage of patients maintain their hearing after five years of treatment with radiosurgery (see study).
Post-Operative Rehabilitation
Hearing rehabilitation is crucial for patients experiencing hearing loss after acoustic neuroma treatment. Options include cochlear implants and auditory brainstem implants (ABI), especially in cases where the cochlear nerve is non-functional. Cochlear implants have proven effective in improving hearing outcomes, although results may vary depending on the type of prior treatment and the integrity of the cochlear nerve.
Additionally, vestibular rehabilitation may be necessary to improve balance and gaze stability, thereby reducing the risk of falls. Specific exercises and rehabilitation programs can help patients adapt to changes in vestibular function following surgery or radiotherapy (see more details).
Conclusions
Treatment for acoustic neuroma requires a multidisciplinary approach that considers both initial treatment options and long-term rehabilitation needs. The choice between surgery and radiotherapy should be based on a careful evaluation of tumor characteristics and patient preferences. Hearing and vestibular rehabilitation is essential for improving patients' quality of life and should be integrated into the treatment plan from the outset. Ongoing collaboration among otolaryngologists, neurosurgeons, and audiologists is crucial to optimize treatment outcomes.
