Введение
Птеригоидное сплетение (от греческого pteryx, "крыло" и eidos, "форма") – тонкое венозное сплетение, расположенное на и внутри латеральной птеригоидной мышцы. Отток происходит по короткой верхнечелюстной вене.
The pterygoid plexus ('/t//ɛ//r//ɪ//g//ɔɪ//d/; from Greek pteryx, "wing" and eidos, "shape") is a fine venous plexus upon and within the lateral pterygoid muscle. It drains by a short maxillary vein.''' Anatomy
It is a venous plexus of considerable size, situated between the temporalis muscle and lateral pterygoid muscle, and partly between the two pterygoid muscles. The plexus features venous valves. The contractions of the lateral pterygoid muscle promote venous drainage. Tributaries
The plexus drains all veins that correspond to the branches of the maxillary artery (however, much of the blood delivered by the maxillary artery is returned by other routes), as well as two additional veins. It receives the following veins:
sphenopalatine
middle meningeal
deep temporal (anterior & posterior)
pterygoid
masseteric
buccinator
alveolar
some palatine veins (palatine vein which divides into the greater and lesser palatine v.)
inferior ophthalmic vein deep facial vein infraorbital vein
Anastomoses
The plexus is connected with the intercranial cavernous sinus by emissary veins passing through the foramen ovale and foramen lacerum.'''

Это венозное сплетение значительного размера, расположенное между височной мышцей и латеральной птеригоидной мышцей, а также частично между двумя птеригоидными мышцами. В сплетении имеются венозные клапаны. Сокращения латеральной птеригоидной мышцы способствуют венозному дренажу.

Отношения
Этот сплетень свободно сообщается с передней лицевой веной; он также имеет сообщение с пещеристым синусом через ветви, проходящие через отверстие Везалия, овальное отверстие и лацеровое отверстие. Вследствие этого сообщения с пещеристым синусом инфекция поверхностных тканей лица может распространиться в пещеристый синус, вызывая тромбоз пещеристого синуса. Осложнения могут включать отек век, конъюнктивы глаз и последующий паралич черепных нервов, проходящих через пещеристый синус. Птеригоидное венозное сплетение становится верхнечелюстной веной. Верхнечелюстная вена и поверхностная височная вена впоследствии соединяются, образуя позадичелюстную вену. Задняя ветвь позадичелюстной вены и задняя ушная вена формируют наружную яремную вену, которая впадает в подключичную вену.
This plexus communicates freely with the anterior facial vein; it also communicates with the cavernous sinus, by branches through the foramen Vesalii, foramen ovale, and foramen lacerum. Due to its communication with the cavernous sinus, infection of the superficial face may spread to the cavernous sinus, causing cavernous sinus thrombosis. Complications may include edema of the eyelids, conjunctivae of the eyes, and subsequent paralysis of cranial nerves which course through the cavernous sinus. The pterygoid plexus of veins becomes the maxillary vein. The maxillary vein and the superficial temporal vein later join to become the retromandibular vein. The posterior branch of the retromandibular vein and posterior auricular vein then form the external jugular vein, which empties into the subclavian vein.
