I had microvascular decompression surgery 8 weeks ago. I have a vascular loop that was compressing my auditory nerve and displacing my vestibular nerve. I have high-pitched pulsatile tinnitus on that side. Since the surgery there has been no relief from the pulsing. The nerve was padded with Teflon sponges at the points of compression. One was at the brain stem, the other was in the internal auditory meatus. How long before the pulsing should subside from the decompression? I am assuming there is still swelling and inflammation, which may result in the continued pulsing. Thank you for your time.
