The pterygomandibular raphe is the tendinous intersection, or seam, between the superior pharyngeal constrictor and the middle portion of the buccinator muscle. It attaches to the pterygoid hamulus superiorly and the posterior end of the mylohyoid line inferiorly. This forms the junction where the deep fourth branchial arch muscles of the pharyngeal wall and the superficial second branchial arch muscles of the face met at the oropharyngeal boundary.
