Dissection of left parotideomasseteric region
Parotid gland and branches of facial nerve, lateral view
The skin and subcutaneous tissues have been removed and the parotideomasseteric fascia cut away. The orbicularis oculi muscle (2) has been reflected anteriorly from the temporal region and the risorius muscle reflected inferiorly in the masseteric region.
