What are the main treatment options for an acoustic neuroma?

The main treatment options for an acoustic neuroma (vestibular schwannoma) include surgical removal, radiation therapy, or active surveillance. The choice of the most appropriate treatment depends on several factors, including the size and location of the tumor, the symptoms it causes, the patient's age, and their overall health. The goal of treatment is to control tumor growth and alleviate symptoms while preserving the function of surrounding nerves as much as possible [1].

Active Surveillance

In some cases, especially when an acoustic neuroma is small and growing very slowly or not causing significant symptoms, doctors may recommend active surveillance. This approach involves regular magnetic resonance imaging (MRI) scans to monitor for any changes in the size or growth of the tumor [2]. This option is often suitable for older patients or those with health conditions that make surgery or radiation riskier. If the tumor begins to grow or if symptoms cause a deterioration in the quality of life, treatment options can be re-evaluated [1].

Surgical Removal

Surgery is a common option for removing an acoustic neuroma, particularly for large tumors or those that cause severe symptoms or compress nearby brain structures [2]. The type of surgery depends on the tumor size and the level of hearing in the affected ear. For some small tumors, it may be possible to preserve hearing. However, surgery can be more complex for large tumors, as they may have already affected the nerves controlling facial movement, hearing, and balance. Removing the tumor can temporarily worsen symptoms due to nerve injury during surgery [1].

Radiation Therapy

Radiation therapy, such as stereotactic radiosurgery (e.g., Gamma Knife), is used to shrink the tumor or limit its growth [1]. Radiation therapy is not a surgical procedure in the traditional sense; rather, it focuses high-energy X-rays on a small area. This option may be preferred for patients who cannot undergo surgery, such as the elderly or those with poor health conditions, or in cases where the tumor is difficult to remove surgically. Radiation therapy may delay the onset of signs of nerve damage, such as hearing loss or facial muscle weakness [2].

Important Considerations When Choosing Treatment

The treatment decision should be made in consultation with a specialized medical team, including a neurosurgeon, an otolaryngologist (ENT specialist), and a radiation oncologist. It is important to discuss the potential risks and benefits of each treatment option, as well as the potential impacts on hearing, balance, and facial function. Early diagnosis can help prevent serious consequences of an acoustic neuroma [1].
