Yep.
About 20 years ago my gran got to the facial palsy stage of Lyme's before it was even considered and diagnosed by a visiting locum doctor who'd grown up in another country.
Antibiotics were given, her face recovered (albeit slowly).
It's a horrendous disease.
May I ask: Did the muscles on the side of the face with the affection also restore or does she have an muscle-atrophy until today on that side?
