The facial lymph nodes are a group of up to 12 superficial lymph nodes of the head situated along the length of the facial vein. Facial lymph nodes are variable in number, usually small. They are further divided into 4 groups: Malar (also infraorbital or maxillary) lymph nodes - situated in the infraorbital region (from the groove between the nose and cheek anteriorly, to the zygomatic arch posteriorly). Nasolabial lymph nodes - situated along the nasolabial sulcus. Buccal lymph nodes - situated immediately superficial to the bucinator muscle, opposite the angle of the mouth. They are one or more in number. Mandibular lymph nodes - situated within tissues superior to the surface of the mandible and anterior to the masseter muscle, and placed alongside and in contact with external maxillary artery and anterior facial vein.
