Anatomy
The left pterygomandibular raphe is a tendinous fibrous band extending from the pterygoid hamulus of the sphenoid bone to the posterior end of the mylohyoid line of the mandible. It serves as a shared line of origin uniting the superior pharyngeal constrictor posteriorly and the buccinator muscle anteriorly.
Clinical notes
The pterygomandibular raphe is the critical intraoral visual landmark for administering inferior alveolar nerve blocks for mandibular dental anesthesia.
