Male Head Buccal Region, Lateral View

Description

Seen in lateral profile, the adult male buccal region occupies the facial soft-tissue envelope between the zygomatic arch superiorly and the body and ramus of the mandible inferiorly and posteriorly. Superficial landmarks include the zygomatic prominence, the nasolabial fold anteriorly, and the contour of the masseter over the mandibular angle posteriorly, with the parotidomasseteric region blending into the cheek. Deep to the skin and subcutaneous fat, the buccinator forms the muscular wall of the cheek, lying medial to the buccal fat pad and anterior to the masseter, while the parotid duct runs horizontally across the masseter before turning medially to pierce the buccinator opposite the maxillary second molar. Facial artery and vein typically course along the anterior cheek near the oral commissure, with branches of the facial nerve traversing the superficial musculoaponeurotic system. This lateral cheek view matters because small shifts in depth and plane determine whether you spare or injure the parotid duct and buccal branches of the facial nerve during perioral laceration repair, facelift dissection, or transbuccal access for mandibular fixation. Buccal space infections can track between the buccinator and overlying tissues, and odontogenic spread from maxillary molars often declares itself as cheek swelling along this corridor. A tight anatomy, with little forgiveness. Common use includes head and neck anatomy teaching on facial compartments, OSCE-style surface anatomy for parotid duct localization, and surgical atlas figures illustrating safe planes for cheek flap elevation and intraoral buccinator approaches. It also suits dental and maxillofacial publications discussing buccal space abscess, sialocele, or post-traumatic duct injury. Anatomical accuracy verified by SciePro's Medical Advisory Board.
