Peripheral Facial Nerve Paralysis Triggered by Alveolar Osteitis.

Peripheral facial nerve paralysis is the most common cranial nerve disorder; it is determined by the branches of the seventh cranial nerve and results in a characteristic facial distortion that is determined in part by the nerve branches involved. Peripheral facial nerve paralysis during dental treatment is very rare; when it does occur, it can be associated with the injection of local anesthetic, prolonged attempts to remove a mandibular third molar, and subsequent infection. Our article presents the case of a patient admitted with unilateral peripheral facial nerve paralysis occurring simultaneously with alveolar osteitis.
