Slight paresis represents normal symmetry at rest, but only a slight asymmetry of facial function with motion. This scale examines the function of four branches of the facial nerve and it was based on the evaluation of facial symmetry at rest, during spontaneous blinking, talking, smiling and voluntary movements of the facial muscles forehead, eye, cheek, mouth by performing the following steps: A radical or conservative parotidectomy was performed as required and the carotid artery and jugular vein were identified in the neck. The authors certify that they have obtained all appropriate patient consent forms. The facial nerve function was assessed and recorded on the first postoperative day following conservative parotidectomy in patients using all 4 scales by 3 otolaryngologists. Grading facial nerve function:
In five cases a radical parotidectomy was performed.
