Dear Jill
Hope that I can try to ease your fears a little bit, my husband 52yrs underwent a total glossectomy and radical neck dissection etc a year ago after a reoccurence. I was so petrified and really didn't expect him to survive the operation but he did. We got to meet somebody before hand who had also had a complete glossectomy and she looked so well two years after her surgery, her speech was understandable as well. My husbands speech is also very good, he has a lot of problems with swallowing but has a peg tube so we manage to cope with that. Doctors manage amazing reconstruction these days. I will be thinking of your dad and your family and hope his surgery is successful
Take care
