Infratemporal fossa: the deep space behind the maxilla
- Artery
Quick facts
- Definition
- Deep space behind the maxilla and below the temporal fossa, beside the pharynx.
- Contents
- Pterygoid muscles, maxillary artery, pterygoid plexus and branches of the mandibular nerve.
- Connects
- With the temporal fossa (above), the orbit and the pterygopalatine fossa.
- Relevance
- Deep facial anatomy, with important vessels and nerves.
- Caution
- Not a target of facial harmonization procedures, but it explains vascular connections of the temple.
The infratemporal fossa is a deep space of the face, located behind the maxilla, below the temporal fossa and beside the pharynx. It does not show on surface examination and is not a target of aesthetic procedures, but its anatomy explains vascular and nerve connections that matter for safety in neighboring regions, such as the temple.
What is in the infratemporal fossa?
| Structure | Note |
|---|---|
| Pterygoid muscles | Take part in chewing |
| Maxillary artery | Gives rise to branches that supply the deep face, teeth and meninges |
| Pterygoid plexus | Network of veins that connects with other venous systems |
| Mandibular nerve (V3) | Its branches carry sensation to the lower face and the tongue |
The exact description varies between sources. What matters here is the general idea: a deep space, full of vessels and nerves.
How does it connect to other regions?
Upward, the infratemporal fossa continues with the temporal fossa beneath the zygomatic arch. Inward, it communicates with the pterygopalatine fossa and, through the inferior orbital fissure, with the orbit. This network of connections explains how deep vessels of the temple are linked to the maxillary artery system.
Why does it matter in facial harmonization?
The temples are a vascular risk area because of superficial and deep branches, such as the temporal arteries. Knowing there is a connection with the maxillary artery and the pterygoid plexus helps understand why the area requires anatomical knowledge and why deep pain and swelling deserve attention. This entry is an anatomy basis, not a technique instruction.

Frequently asked questions
What is in the infratemporal fossa?
The pterygoid muscles, the maxillary artery, the pterygoid venous plexus and branches of the mandibular nerve, such as the inferior alveolar and lingual nerves.
How is the infratemporal fossa related to the temple?
The infratemporal fossa continues upward with the temporal fossa beneath the zygomatic arch. This explains why deep vessels of the temple are linked to the maxillary artery.
