She is out of surgery, awake, talking, coherent and responsive, both mentally and physically.
The surgeons report that they were able to remove the entire mass. (It was 7 cm x 6 cm x 5 cm -- no wonder she's had some headaches!)
She's in recovery, and we'll be able to see her once she gets moved to the ICU.
Also, Papa would like me to add that they were able to replace most of the bone, so rather than a full titanium plate, they only had to use some smaller titanium stabilizers, which will be permanent. (I know that was my biggest concern.)
More info once we've seen her.
Go forth and be merry!
