ABSTRACT

The facial nerve is the main anatomical structure that the surgeon should consider while performing an extraoral surgical approach to the mandibular angle or condyle or temporomandibular joint. Impairment of facial nerve function interferes with emotional expression, muscles of facial expression, also causes functional deficits, and can create a grotesque cosmetic deformity. Most surgical approaches to this region have been specifically designed to offer maximal protection and minimize injury of neural structure. According to the literature, facial paralysis is transitory in the majority of cases and usually disappears within 9 to 14 weeks, but may last for up to 6 months. So primary aim of this reterospective study is to evaluate the Prevalence and degree of facial nerve injury with different extra oral approaches for surgeries involving mandibular angle or condyle or TMJ.
