Arteries supplying the temporal bone are derived from various sources.
The chief are:
- Stylo-mastoid from posterior auricular: it enters the stylo-mastoid foramen.
- Tympanic from internal maxillary: it passes through the Glaserian fissure.
- Petrosal from middle meningeal: transmitted by the hiatus Fallopii.
- Tympanic from internal carotid whilst in the carotid canal.
- Auditory from the basilar: it enters the internal auditory meatus, and is distributed to the cochlea, vestibule, &c.
Other less important twigs are furnished by the middle meningeal, the meningeal branches of the occipital, and by the ascending pharyngeal artery. The squamosal is supplied on its internal face by the middle meningeal, and externally by the branches of the deep temporal from the internal maxillary.
