Abstract

Variations in the relationship of the retromandibular vein to the facial nerve have been widely reported due to their relevance for surgical approaches in parotid, osteotomy and mandibular condyle surgery. In the context of the retromandibular retroparotid approach, remaining deep to the retromandibular vein is advised to decrease the likelihood of encountering the facial nerve during mandibular condyle surgery. In the present report, an unusual variant of the superficial temporal vein lying superficial to the facial nerve is described. This represents a variation of the venous branching pattern within the parotid gland, whereby the superficial temporal vein joins the maxillary vein inferior to its usual communication. These findings are discussed in the context of commonly used surgical approaches to the mandible for condylar trauma or osteotomy surgery.
