Schematic drawing representing the trajectory of the broken glass in the right preauricular region. The broken glass was able to reach the external carotid artery without sectioning the facial nerve or any other significant neurovascular structures by passing through the triangular space delimited by the temporal and cervical branches of the facial nerve. 1 Superficial temporal artery, 2 Maxillary artery, 3 Auriculotemporal nerve, 4 Facial nerve trunk, 5 Temporal division of the facial nerve (temporofacial trunk), 6 Cervical division of the facial nerve (cervicofacial trunk), 7 Parotid gland, 8 Retromandibular gland, 9 External carotid artery
