1. Introduction
2. Course and relations
3. Branches of maxillary artery

2. INTRODUCTION
´ Maxillary artery is the larger terminal branch of external carotid artery given
off behind the neck of the mandible
´ It has wide territory of distribution and supplies
´ External ,middle ears and auditory tube

3. ´ The upper and lower jaws
´ The palate and root of pharynx

4. ´ The nose and paranasal sinuses
´ The Duramater
´ The muscles of temporal and infra temporal regions.

5. COURSE
Dissection
´ External carotid artery divides into its two terminal branches, maxillary and
superficial temporal on the anteromedial surface of the parotid gland. The
maxillary artery, appears in this region

6. The maxillary artery is divided into 3 parts by the LATERAL PTERYGOID MUSCLE
1. the first part ( mandibular part)
2. The second part (pterygoid part)
3. The third part (pterygopalatine part)

7. The first part(mandibular part)
1. The first (mandibular)
part runs horizontally
forwards, first between
the neck of the
mandible and the
sphenomandibular
ligament, below the
auriculo-temporal
nerve and then along
the lower border of

8. The second part(pterygoid part)
´ The second (pterygoid) part runs upwards and forwards superficial to the
lower head of the lateral pterygoid.

9. The third part(pterygopalatine part)
´ The third (pterygopalatine) part passes between the two heads of the
lateral pterygoid and through the pterygomaxillary fissure, to enter the
pterygopalatine fossa where it lies in front of the pterygopalatine ganglion
