I was diagnosed with HPV16+ OSCC in March 2023. I had TORS robotic surgery April 2023. I had a right neck dissection with all lymph nodes removed and TORS surgery to remove primary tumor of 3cm at base of tongue. . All margins clear. Also, I have just completed 30 rounds of Proton Radiation. As far as presurgery I don't recall doing much but waiting for the Surgery. The biggest issue I had was dysphagia and Not being about to swallow (eat or drink) for about two weeks after surgery. I would start doing mouth, tongue and swallowing exercises today. If you have a Speech therapist they can help you with this. As far as post op. The pain is fairly severe for one week after surgery. I had alot of mucous where you feel like you are almost drowning. It will be hard to eat and drink. Think soft foods and Boost drinks. I had pain medications which helped tremendously. My current side affects are loss of feeling in side of jaw up into the ear on right side. Lip droops a little on that side. Scar has pretty much healed. Good luck to you . You can do it!
