Hi Dr David,
Thank you for posting your query.
There is very little risk of damaging the
facial nerve while doing skin or cosmetic surgery on the face, as the facial nerves are not so superficial.
The only place where there is some risk is in front of the ear, where
parotid gland is located.
So, you can relax and perform your procedures.
I hope my answer helps. Please get back if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
