Figure 1From: Impact of removing mastoid process for advanced parotid cancer on facial nerve identification, preservation and reconstruction Recurrent parotid cancer. a). MRI. b). Intraoperative findings ( before removing mastoid process). Working space is significantly narrow (↔) between mastoid process and the tumor. 1) the tumor, 2) mastoid process. c). After removing mastoid process. Expanding the working space facilitates identification of the facial nerve and dissection of parotid tumor without retracting the facial nerve (arrow).Back to article page
