Mini Article Review: microsurgery or radiosurgery
« on: February 07, 2017, 06:43:45 pm »
I just finished reading a recent abstract (J Neurosug 2016 Dec) that the community may find interesting: https://www.ncbi.nlm.nih.gov/pubmed/27035174 . I call it a mini review since I've only got, and therefore read, the abstract.

The article compares microsurgery (MS) to stereotactic radiosurgery (SRS) for tumors ≤ 2.8 cm in diameter.

My summary is:

n = 399 patients
Preservation of preoperative Class A hearing: 14.3% MS, 42.9% SRS
Serviceable hearing preservation: 42.8% MS. 85.7% SRS
Facial nerve dysfunction (HB III-IV): 11% MS, 0% SRS
Need for subsequent intervention: same (2 patients for MS and SRS)

The follow up time, particularly for SRS was short. It would be interesting to see how things change after 5 year and 10 years. I suspect that hearing will continue to decline, but facial nerve and subsequent intervention figures would remain unchanged. Stereotactic radiosurgery appears to be a clear winner for tumors ≤ 2.8 cm in diameter. No mention of CSF leak, hydrocephalus, headaches, trigeminal nerve dysfunction, meningitis or possibility of malignant transformation in the abstract.

What I'm reading here is consistent with previous reading.

So based on this study, a 2.7cm tumor could be a candidate?  I was told that my tumor would swell and causeproblems.

Up to 3.0 cm, most will treat with Gamma Knife.
