Buccinator Muscle, Anterior View

Description

Emerging from the maxillary and mandibular alveolar processes and the pterygomandibular raphe, the buccinator forms the muscular wall of the cheek as it runs anteriorly toward the modiolus at the angle of the mouth. From this anterior perspective, its fibers converge medially to blend with orbicularis oris, placing the muscle lateral to the oral vestibule and deep to the buccal mucosa. Superiorly it approaches the region of the maxillary molars, and inferiorly it tracks toward the mandibular molar segment, defining the lateral boundary of the oral cavity. Clinically, buccinator anatomy matters whenever you are trying to control the oral commissure and cheek during repair, reconstruction, or denture fitting. Its intimate relationship to the parotid duct papilla opposite the maxillary second molar makes this muscle a practical landmark when teaching duct cannulation and when planning intraoral incisions that risk duct injury. Weakness after facial nerve (buccal branch) palsy classically produces food trapping in the buccal sulcus and impaired blowing or whistling. A simple deficit with real functional impact. Use this plate for head and neck anatomy teaching in dental, speech and swallowing, and facial plastic surgery curricula, and for publications discussing the modiolus, oral competence, or buccinator myomucosal flap design in cleft and intraoral reconstruction. It also fits well in patient-facing materials on facial nerve palsy and oral rehabilitation where clear orientation to the corner of the mouth is needed.
