Three months back I had a craniotomy/mastoidectomy surgery to fix a CSF leak in my ear. Post-op recovery seems very good except recently i have started getting a persistent mild salty taste in my mouth. No draiage from nose. I see a few other posts in this group about AN patients having this symptom with delayed onset 3-6 months after surgery. Wanted to know if this is a cause for concern in terms of a relapse of leak or could be just due to the nerves that were cut during the surgery and I have to live with this? What kind of tests can be done to rule in/out possibilities?
