Lipoma Removal from base of Skull. I have a lipoma & has grown to approximately 4 inches wide by 2 inches high. Any suggestion?

I decided that I must remove it, and met with 4-5 plastic surgeons. Some suggested a local anesthesia in office, while some suggested full anesthesia in a hospital. Also, one Dr. Mentioned it would damage nerves in back of my head and I wouldn't have feeling there post surgery. Is this true? I'm just totally confused and nervous about this decision and which route to go. Also,can it be the reason for ear and head pressure that I have been having? Will removal help that?
