Quizplus · Accepted Answer

The pterygoid venous plexus is a highly vascular area and can potentially lead to rapid systemic absorption of the anesthetic when administering the PSA injection. This can result in undesirable side effects such as CNS and cardiorespiratory depression. Therefore, it is important to use proper injection technique and avoid depositing the anesthetic agent into the plexus.
