Annie,
I had CK done here in Boston last April (almost 10 mos ago). My hearing is almost what it was at time of treatment (just a hint below)... at time of treatment, my hearing in my left (AN) ear was just at the bottom of the "normal" range, with issues for low tones and voice recognition at 100%. My last one (this past October) showed my left ear just below the "normal" range, still issues with low tones, voice recognition at 96%. My next hearing test is in 2 weeks...
For me (and this is only my attitude, so I only speak for myself), my preference was " go non-invasive first, then, if need be, go invasive"... but, that does not apply to everyone. My family wanted me to have it cut out since I lost a sister to a brain tumor (malignant childhood growth).
Annie, overall, my hearing is fine, I use my AN ear as my "phone" ear and except for a hint of loss (last test showed that from previous test, I lost approx 10-15 db), overall... I hear fine and... got word in December that the AN is dying it's slow death (beginning stages of necrosis)! But don't tell my spouse... He thinks it's selective hearing!
I use my AN as my excuse..
shhhhhhhh...Phyl
