Which are the symptoms of Vestibular Schwannoma?

Symptoms of Vestibular Schwannoma

Vestibular Schwannoma, also known as acoustic neuroma, is a benign tumor that develops on the vestibular nerve, which connects the inner ear to the brain. This type of tumor usually grows slowly and can cause a variety of symptoms depending on its size and location. It is important to note that not all individuals with vestibular schwannoma will experience symptoms, and the severity of symptoms can vary from person to person.

1. Hearing Loss and Tinnitus

One of the most common symptoms of vestibular schwannoma is gradual hearing loss in one ear. This hearing loss may initially be mild and go unnoticed, but it can progress over time. Individuals may also experience tinnitus, which is a ringing, buzzing, or hissing sound in the affected ear.

2. Balance and Coordination Issues

Vestibular schwannomas can affect the vestibular system, which is responsible for maintaining balance and coordination. As the tumor grows, it can disrupt the normal functioning of this system, leading to symptoms such as unsteadiness, dizziness, and difficulty with balance. Individuals may feel as if they are constantly off-balance or have trouble walking in a straight line.

3. Facial Weakness or Numbness

In some cases, vestibular schwannomas can compress the facial nerve, resulting in facial weakness or numbness. This can cause difficulty in making facial expressions, drooping of the affected side of the face, or a loss of sensation in the facial area.

4. Headaches

Headaches can occur as a result of vestibular schwannoma, although they are not always present. These headaches are typically dull and persistent, and they may worsen over time. The exact cause of these headaches is not fully understood, but they may be related to the pressure exerted by the tumor on surrounding structures.

5. Vertigo

Vertigo is a sensation of spinning or whirling, often accompanied by nausea and vomiting. It can be a symptom of vestibular schwannoma, particularly when the tumor grows larger and starts to affect the balance centers in the brain. Individuals may experience sudden episodes of severe vertigo that can last for minutes to hours.

6. Pressure or Fullness in the Ear

Some individuals with vestibular schwannoma may experience a sensation of pressure or fullness in the affected ear. This feeling is often described as similar to having water or something blocking the ear canal.

7. Changes in Vision or Eye Movement

In rare cases, larger vestibular schwannomas can put pressure on the nearby optic nerve, leading to changes in vision. This can include blurred or double vision, difficulty focusing, or abnormal eye movements.

8. Difficulty Swallowing or Hoarseness

If the tumor grows large enough to compress the nerves responsible for swallowing or vocal cord function, individuals may experience difficulty swallowing or hoarseness. This can be due to the tumor pressing on the nerves that control these functions.

If you experience any of these symptoms or have concerns about your hearing or balance, it is important to consult with a healthcare professional. They can perform a thorough evaluation, including a physical examination and diagnostic tests, to determine the cause of your symptoms and develop an appropriate treatment plan.
