The pterygomandibular fold refers to the fold of mucosal tissue that overlies the pterygomandibular raphe and the needle should always be inserted lateral to the fold. The barrel of the syringe usually needs to be positioned over the contralateral premolars so that the needle tip can contact bone just superior to the lingula at the appropriate.

The boundary of the pterygomandibular space is as follows: medial pterygoid muscle on the medial side, medial surface of ramus on the lateral side, pterygomandibular raphe on the anterior side, parotid gland on the posterior side, and lateral pterygoid muscle on the superior side. Abscesses in this area often arise due to odontogenic causes and. The pterygomandibular raphe attaches superiorly to the medial pterygoid and inferiorly to the posterior mandible. This forms a junction between the oral cavity, oropharynx, and nasopharynx.

The attachments extend back into the pterygomandibular raphe. The buccinator is innervated by the buccal branch of the facial nerve. The muscle belongs to the mimetic muscle system and has a unique functional structure allowing for movement comparable to peristaltic motion. Its detachment can result in an impaired bolus transport Inferiorly these fascial layers converge upon the greater cornu of the hyoid. The anterior border is the pterygomandibular raphe, and the posterior boundary consists of the carotid sheath and prevertebral fascia. Within the parapharyngeal space, there is fatty connective tissue, which can be dissected with blunt dissection alone The superior pharyngeal constrictor arises from the pterygoid hamulus, pterygomandibular raphe, mandible, and tongue; passes posteromedially; and inserts to the posterior raphe.

Gingival and retromolar infections and malignancies can spread to the MS along the pterygomandibular raphe. Buccal pathologies can also travel along the buccinator muscle into the pterygomandibular raphe In addition, the false-positive cases were probably due to the pushing margin, which means the tumor compressed and pushed the constrictor muscle toward the parapharyngeal fat but preserved the lateral fascia of the superior pharyngeal constrictor muscle near the pterygomandibular raphe
