Buccal Branch of the Facial Nerve, Anterior View

Description

Centered on an anterior skull view, the buccal branches of the facial nerve (rami buccales nervi facialis, CN VII) course superficially across the cheek from the parotid region toward the modiolus and upper lip. Lateral to the piriform aperture and inferior to the orbit, the branches fan medially over the maxilla in the expected plane of the superficial musculoaponeurotic system, crossing toward the perioral musculature. Adjacent cranial nerve territories are also visible around the orbit and nasal bridge, helping distinguish facial motor branches from nearby sensory distributions. Color coding separates bony landmarks from yellow nerve pathways and accompanying blue superficial veins. Understanding the buccal branch matters because it is the dominant motor supply to key midface muscles, including buccinator and parts of orbicularis oris, and injury produces oral incompetence, asymmetrical smile, and food trapping in the vestibule. Cheek surgery lives in this anatomy. Rhytidectomy, parotidectomy, and excision of midcheek lesions place the buccal branches at risk as they pass anterior to the parotid gland and traverse variable anastomoses with the zygomatic and marginal mandibular branches. The anterior perspective also supports teaching of safe dissection planes relative to the parotid duct and the facial vessels at the nasolabial region. Plastic surgery, otolaryngology, and maxillofacial texts commonly need a clean depiction of buccal branch topography when discussing SMAS elevation, parotid approaches, and repair of traumatic facial nerve lacerations. It also fits head and neck anatomy courses and clinical teaching on patterns of facial palsy, helping learners separate central facial weakness from peripheral CN VII lesions by mapping muscle groups affected in the cheek and upper lip.
