POTENTIAL RECOVERY OF FACIAL NERVE LESIONS

Abstract

Objective evaluation of facial nerve paralysis represents a unique challenge to the clinician . Electromyography and the acoustic reflex tests have been widely used as neurophysiological tests in an assessment of facial nerve function.

The role of electrophysiological tests in the assessment of potential recovery and detection of prognosis compared to the clinical findings is still doubtful.

This study arms to achieve an early prognostic pattern for facial nerve lesions as well as following the potential recovery of the nerve. This was depending upon electrophysiological tests in comparison to ' clinical assessment. This may be helpful in decision making of treatment.

Facial nerve has special characters in its anatomy and its variations must be studied seriously as well as its surgical landmarks . Microanatomy and Neuropathophysiology are important items for classification of injury and they were discussed in details.

Most important causes of facial lesions in this study were Bell s palsy, trauma (especially surgical), otitis media and viral infection.

Clinical approach to any case of facial palsy should include important symptoms as otalgia, hyperacusis, epiphora ear discharge and taste affection, while clinical examination should include accurate grading of the motor power .
