Acoustic Neuroma – Diagnosis and Treatment
Diagnosis
Diagnosing an acoustic neuroma often starts with a detailed conversation about symptoms. Common signs may include hearing loss in one ear, ringing in the ear (tinnitus), dizziness, balance problems, or facial numbness.
Because these symptoms can develop slowly and may look like other inner ear issues, finding an acoustic neuroma early can be difficult.
A physical examination, including a close check of the ear, is a key first step. Specialists carefully check hearing and balance to see if there is any nerve involvement.
| Main Tests for Acoustic Neuroma | What It Detects |
|---|---|
| Physical/Ear Exam | Initial signs and ear health |
| Audiogram (Hearing Test) | Hearing loss, speech understanding |
| MRI Scan with Contrast | Tumor size and location, even very small |
| CT Scan (if MRI not possible) | Tumor presence (may miss tiny tumors) |
Hearing Tests
An audiologist often performs an audiogram or hearing test. In this test, the audiologist plays sounds and words in each ear at different volumes and tones.
The patient signals when they hear each sound, which helps pinpoint even minor hearing loss or speech understanding problems related to the tumor.
Imaging Tests
Doctors primarily use magnetic resonance imaging (MRI) scans with contrast dye to detect acoustic neuromas. MRI reveals tumors as tiny as 1–2 millimeters.
If a person cannot have an MRI, doctors may use a CT scan, but it isn’t as sensitive for finding smaller tumors.
Other Symptoms Considered
Doctors also check for facial weakness, headaches, vertigo, trouble swallowing, trouble with the balance system, or mental confusion.
When they spot tumor growth in the vestibular nerve or balance nerve, it helps confirm the diagnosis.
Treatment
Watchful Waiting
Some people with acoustic neuroma do not need immediate treatment. If the tumor is small, slow-growing, or not causing problems, health providers may suggest regular monitoring instead of action right away.
This approach is often called “watchful waiting.”
Patients in this group usually get MRI scans and hearing tests every 6 to 12 months. These regular check-ups track tumor growth or new symptoms. If the tumor grows or causes new issues, doctors may recommend other treatments.
Doctors most often use monitoring for older adults or those who are not healthy enough for surgery or radiation. Monitoring is also an option if the tumor is in a spot where treatment could be risky.
Surgical Removal
Surgeons sometimes recommend surgical removal, especially if the tumor is large, growing, or causing troublesome symptoms. In this treatment, an experienced surgeon removes as much of the tumor as possible, aiming to protect the facial nerve and keep damage minimal.
Doctors select the surgical method based on the size and position of the tumor, the person’s hearing status, and other health factors. The two main ways to reach the tumor are through the inner ear or a small opening in the skull.
During surgery, the person receives general anesthesia. Surgeons may not always achieve complete removal if the tumor is closely wrapped around important nerves. Sometimes, they can only remove part of the tumor safely.
Possible complications of surgery:
| Complication | Description |
|---|---|
| Hearing loss | Sometimes on the side of the surgery. |
| Balance trouble | Often happens but usually gets better with time. |
| Facial weakness or numbness | May affect muscles used for facial movement. |
| Ringing in the ear (tinnitus) | May appear or worsen. |
| Headache | Can last for days or weeks. |
| Fluid leak (cerebrospinal fluid) | May leak through the wound after surgery. |
| Infection (meningitis) | Rare but serious, an infection of the brain’s lining. |
| Stroke or bleeding in the brain | Extremely rare. |
Recovery time differs from person to person. Balance therapy, hearing support, and physical therapy help with rehabilitation.
Focused Radiation Treatments
Radiation can also control or shrink acoustic neuromas. Doctors often choose this if surgery is too risky or if the tumor is small and not growing quickly. People with health problems might also benefit from this option.
Types of radiation therapy:
-
Stereotactic Radiosurgery: This is a non-invasive radiation technique that uses multiple highly focused beams aimed at the tumor from different angles. The objective is to halt tumor growth while minimizing damage to surrounding healthy tissue and nerves. It is typically completed in a single session and does not require surgical incisions.
- Doctors use this when the tumor is less than 2.5 centimeters across.
- Benefits appear gradually over months or years.
- Follow-up with imaging and hearing tests remains important.
- Fractionated Stereotactic Radiotherapy (SRT): The patient receives a smaller dose of radiation over several sessions. This can help slow the tumor’s growth and aims to protect healthy brain tissue.
- Proton Beam Therapy: Doctors use beams of protons (tiny charged particles) to target the tumor. This type delivers high-dose radiation to the tumor and reduces the amount reaching nearby healthy structures.
Doctors choose the best type of radiation based on the tumor’s size and position, as well as the person’s health and personal needs. All approaches aim to keep normal tissue safe while controlling the tumor.
Symptom Management and Rehabilitation
People with acoustic neuroma may also need help managing symptoms, even while receiving treatment for the tumor itself.
These supportive therapies address hearing loss, balance problems, or other complications linked to either the tumor or its treatment.
- Hearing Support: Providers may suggest devices such as hearing aids or cochlear implants if the tumor or treatment causes hearing loss.
- Physical Therapy: Therapists help patients regain balance, move safely, and reduce dizziness.
- Occupational Therapy: Occupational therapists assist with everyday tasks and improve quality of life.
Types of support often offered:
- Balance retraining
- Speech and language therapy (if needed)
- Counseling and education about how to manage long-term changes
Specialists such as audiologists, physical therapists, and occupational therapists contribute to recovery. Many people return to normal activities with time and support.
Managing Everyday Challenges and Finding Support
Facing symptoms like hearing loss or changes in facial muscles can be difficult. Choosing a treatment plan may also feel overwhelming at times. Learning more about acoustic neuromas and available treatments can make decisions easier.
It helps to ask questions and speak with healthcare providers, audiologists, or counselors. Some people find it useful to connect with others who have gone through similar experiences and hear their stories.
Building a solid network of support is important. Friends, family, and support groups can all play a key role.
Ways to manage and seek support:
| Tip | Benefit |
|---|---|
| Reach out to support groups. | Gain shared experiences and advice. |
| Talk with professionals. | Get accurate information and reassurance. |
| Stay connected with loved ones. | Emotional comfort and encouragement. |
| Learn about acoustic neuromas. | Feel more confident in decisions. |
Having support and good information can ease stress and help manage the day-to-day impacts of acoustic neuroma.

Questions You May Hear from the Doctor
Health providers ask questions to understand your problem better. Be ready to answer things like:
- When did your symptoms begin?
- Are your symptoms steady, or do they come and go?
- How severe are your symptoms?
- Do you have a family history of similar health problems?
- How well can you hear through the affected ear? (For example, can you use it for phone calls?)
- Do you have frequent or past headaches?
Doctors ask about your general health, past illnesses, and whether symptoms affect your daily life.
Tip: If you can’t remember something during your visit, check your notes or ask for a moment to think. Take charge of your health by being informed and ready during your appointment.
