What is the pterygoid plexus?

The pterygoid plexus is indeed a dense venous plexus located on both sides of the lateral pterygoid muscle. This network of veins is crucial for the venous drainage of the deep facial regions, including the nasal cavity, paranasal sinuses, and the muscles of mastication. It connects with other venous systems, such as the facial vein and the cavernous sinus, playing an important role in regulating blood flow and pressure in the head. Understanding the pterygoid plexus is vital for dental professionals, especially in relation to procedures that might impact this area, as it is closely associated with the maxillary nerve and can be involved in the spread of infections if not managed properly.
