The muscle least related to the pterygomandibular raphe is the lateral pterygoid. The pterygomandibular raphe primarily connects the superior pharyngeal constrictor and the buccinator muscles, while the medial and lateral pterygoid muscles are involved in the movement of the jaw but do not have a direct attachment to the raphe. Heres a breakdown of the relationships:
Muscle Relationships to the Pterygomandibular Raphe

Plays a role in swallowing and constricting the pharynx.
While not directly attached, it is located near the pterygomandibular raphe and contributes to jaw movement.
