I had parotid surgery in NYC by the chief surgeon of head and neck at NY PRESBYTERIAN HOSPITAL. Yes it is dangerous if it’s not done by somebody that knows what they are doing or doesn’t have a lot of experience and I mean a lot. My surgery took 5 1/2 hours and my scar is so tiny. My tumor was benign thank God. And my doctor was also a plastic surgeon. If it were me in your position I would get a second opinion From the very best Dr . There is no reason to be in pain if it can be helped.
