I had surgery in September 2004 on my tongue for squamous cell carcinoma. They removed 30% of my tongue. In addition, they did a partial neck disection that included an incision from behind my left ear down to the botom of my chin.
I never had a problem with my speech after the operation. The real problem was dealing with the radiation therapy that followed. I had 30 treatments over a period of 6 weeks. The side effects included loss of taste or a nasty metallic taste,and loss of saliva production(permanent). To be honest, when I got to treatment number 20 and knowing I had 10 to go, I wasn't sure I was going to make it. Also during this time I had developed ulsers in my mouth and could not eat solid food. The liquid diet (Boost) was not near adequate and I lost 50 pounds. I did however, make my way through it and after joining a health club and changing my diet to include high protein supplements, I have gained back my weight to 170 pounds which is what I should weigh. I have gone through several check ups since my last radiation treatment and all is well. If there is anything I can suggest that is worth much is to get some supplement like Cytogainer by Cytosport. It will help you to maintain your weight during treatment and you won't suffer as I did.
