However, they do recur or present with distant metastases many years after apparent disease-free survival. An extracapsular dissection for benign pathology, away from the main branches of the facial nerve is an option, and even endoscopically-assisted parotidectomy can be effective in selected patients. Seventy-two consecutive parotid gland tumors were analysed with high-resolution ultrasonography (12 MHz) with color Doppler imagining. the differential diagnosis of diseases that occur with increased volume in the head, lymphadenopathy, drooling, dysphagia, and progressive weight loss.
