Overview
If left untreated, an acoustic neuroma can block the flow of cerebrospinal fluid and cause hydrocephalus, which may lead to severe vision problems and difficulty breathing and swallowing. Acoustic neuroma patients have a very good prognosis with minimal complications if treated.[1] Closing </ref> missing for <ref> tag
- Acoustic neuroma patients have a very good prognosis with minimal complications if treated.
- Forty to sixty percentage of small tumors may not require treatment.
- A control rate of greater than 90% is found in tumors treated with focused radiation.
- A recurrence rate of less than 5% has been found following surgery.
- Patients experience similar quality of life whether treatment is observation, radiation, or surgery.
- With the emergence of magnetic resonance imaging(MRI) with gadolinium, acoustic neuroma tumors as small as 2 mm in diameter can be accurately detected. Due to improved surgical techniques and early diagnosis, the morbidity associated with surgical removal of these lesions is reduced.[2] In select group of patients(patients older than 65 years with acoustic neuroma): however, no treatment may be the most appropriate management.[3]
Complications
Complications of acoustic neuroma include:[4]
- Hydrocephalus
- Recurrence of tumor
