Hi Rlm,
Welcome to the forum and good luck on Wednesday. You will find many survivors here that did get other opinions before beginning their treatment and they did this for many reasons. You didn't mention anything about your staging, lymph nodes, radiation or chemo. Are you having a glossectomy only?
I too, did not go for a second opinion. I was referred to my surgeon by several of my colleagues and friends. Like Aimee, I had a partial glossectomy and neck dissection. I have not looked back about getting another opinion, as I had complete confidence in my surgeon. It would be great if you could get past this as second guessing yourself after the fact, can be self-destructive.
