para,
This is a huge topic and there are thousands of posts on the pros and cons of both. My sceptisism tells me that surgeons promote surgery coz of the $. But before everyone tells me off on this one, there are a couple of major pre determining decisions you need to make which will guide you to the most appropriate treatement for yourself.
1. If you have a striong aversion to either surgery or radiation then go with the other.
2. Research both options as to specific doctor / technician percentages. that is, medicos will give you industry percentages for success, facial paralysis shrinkage etc. Don't accept industry data, ask for that doctor's percentages.
3. Review the many posts on this forum on this topic and remember, everyone is different.
One given is that there is also a financial and job impact. Surgery will keep you off work for around 6 weeks post surgery (at best). radiation treatment - I had mine over 5 days and went back to work after each treatment.
