Introduction

The head module contains three groups of regions:

  • Cranial

  • Facial

  • Airways

The cranial regions include the scalp, temporal region, cranial cavity, orbit, and ear. The importance of the cranial cavity contents makes it the dominant group of images represented here. They are divided into congenital, hemorrhage, tumors, trauma, and infection.

The facial regions include superficial regions (face, parotid) and deep regions (infratemporal region, pterygopalatine fossa, deep styloid region).

The airway regions include nasal regions (nasal cavity, paranasal sinuses, nasopharynx), oral regions (oral cavity, oropharynx), and laryngeal regions (larynx, laryngopharynx).

Some miscellaneous images are grouped together for convenience (e.g., Paget's disease).
