Indications for Surgery

The established surgical indications for acoustic neuroma surgery include:

1. Size of the tumor: Larger tumors that are causing symptoms or posing a threat to nearby brain structures are often indicated for surgery. Generally, tumors larger than 1.5 cm in diameter are considered for surgical removal.
2. Location of the tumor: If the tumor is compressing vital structures, such as the brainstem or cranial nerves, surgery may be indicated to relieve this pressure.
3. Symptoms: Surgery is often recommended if the patient is experiencing debilitating symptoms, including severe hearing loss, tinnitus, vertigo, facial numbness or weakness, and difficulties with balance.
4. Patient’s age and general health: Surgery is more commonly recommended for younger, healthier patients who are more likely to tolerate the procedure well. In older patients, or those with significant comorbidities, the risks of surgery may outweigh the potential benefits.
5. Failure of other treatments: If the tumor continues to grow or symptoms worsen despite conservative management (observation) or radiation therapy, surgery may be indicated.
6. Patient’s preference: Some patients may prefer a surgical approach for the possibility of complete tumor removal, despite potential risks.
