Acoustic Neuroma: Q&A
1. What are the early symptoms of acoustic neuroma?
The early symptoms of an acoustic neuroma primarily involve unilateral hearing loss, particularly difficulty hearing high-frequency sounds.Tinnitus in the affected ear is often a persistent, high-pitched sound.Dizziness and a sense of imbalance may also occur.
2. Is an acoustic neuroma a malignant tumor?
An acoustic neuroma is a benign tumor that grows slowly and does not spread to other parts of the body.The incidence rate is less than one case per 20,000 people annually, and it is most commonly found in individuals aged 30 to 60.
3. What are the surgical treatment options for acoustic neuroma?
The surgical approach for an acoustic neuroma is selected based on the tumor's size and location.The translabyrinthine approach is suitable for patients who have already lost their hearing.The middle cranial fossa approach is suitable for small tumors in patients who wish to preserve their hearing.
4. What is minimally invasive treatment for acoustic neuroma?
Stereotactic radiotherapy, such as Gamma Knife, is a primary minimally invasive treatment for acoustic neuromas; it uses high-precision radiation to shrink the tumor.
5. Does acoustic neuroma surgery affect the facial nerve?
The facial nerve runs parallel to the auditory nerve and may be affected during surgery.Intraoperative facial nerve electrophysiological monitoring allows for real-time assessment of nerve function, thereby improving the rate of nerve preservation.Facial nerve preservation rates are higher for small tumors.
6. Can hearing be preserved after acoustic neuroma treatment?
Hearing preservation depends on tumor size and preoperative hearing levels.Patients with small tumors and good preoperative hearing have a higher chance of preserving hearing after surgery or radiotherapy.
7. Follow-up after acoustic neuroma treatment
Undergo regular post-operative MRI follow-ups to monitor for residual tumor or recurrence.Monitor facial nerve function recovery and perform facial muscle exercises.Undergo hearing tests to assess changes in hearing.
