Facial paralysis may be caused inadvertently by medical intervention or may at times be an inseparable part of a procedure in which the facial nerve must be removed.
Facial paralysis may be caused by:
- Cosmetic procedures, such as facelifts
- Dental procedures
- Mastoid or parotid surgery
- Nerve blocks in the face
- Skull base surgery
Not all facial paralysis after procedures is permanent. Procedures in the area of the nerve will often cause temporary paralysis (neuropraxia) and recovery can be seen over several months.
If the nerve has been transected during surgery, it is necessary to reconstruct the nerve either by direct suturing or by grafting and in certain cases other procedures are needed.
