I had a stapedectomy 17 days ago and I could notice a huge improvement in hearing immediately after the surgery. I heard the heartbeat sounds in my ear, cracking, shooting pain but that went away. There has been a constant hissing in the operated ear for the past 6 days; it can best be described as air escaping from a tire. Is this normal? Has anyone else had a stapedectomy with these results? My hearing is adjusting and improving everyday and is not as hypersensitive as it was in the beginning but this constant hissing is just not going away. Any feedback would be greatly appreciated! Thank you.
