Hi. My name is Heather. I am 55 yo and have suffered with severe nosebleeds since I was a young child. My grandfather and his generation of HHT suffers told my mom in the 1970's not to let them cauterize my nosebleeds (by old-school traditional cauterization). That just created more and more scar tissue in their nasal cavities and new blood vessels grow and bleed anyway.
In the mid and late 1980's, I had YAG laser treatments every month in Minneapolis for several years. That really helped lessen the bleeds and the laser did not create scar tissue.
About age 50, I finally started seeing the HHT specialist at Mayo Clinic in Rochester, MN.
I now get infusion therapy treatments of a generic or biochemical similar med to Avastin. The treatments have been LIFE-CHANGING for me. There are also other options of treatments or trials being studied for HHT. I wonder if the cauterization you get now is similar to the YAG laser treatments I used to get. I tried to request laser cauterization from an ENT 10-15 years ago and he said they only use it in very severe cases and only completely under with anesthesia.
Best of luck to you!
