  3. 3. INTRODUCTION • Clinicians : anterior and posterior triangles • Anatomists : pioneered the work on fascial spaces and anatomy • Cross sectional imaging helped clinicians , anatomists and surgeons in dividing it into fascial compartments
  4. 4. • Basis for dividing neck into spaces and compartments : arrangement of superficial and deep layers of cervical fascia • The importance of this spaces is that they may limit to some degree the spread of most infections and some tumors • A proper understanding of their anatomy will also aid in the diagnosis of various conditions INTR0DUCTION
  5. 5. NECK SPACES Described in relation to the hyoid bone. • Suprahyoid Spaces. • Infrahyoid Spaces. • Spaces extending up to the entire length of the neck.
