Nasal cavity and paranasal sinuses radiologic anatomy

  1. 1. + Nasal Cavity and Paranasal Sinuses
  2. 2. + Roadmap Gross Introduction Positioning Anatomy Radiographic X Ray CT Anatomy MRI Questions
  3. 3. + Introduction
  4. 4. + Introduction  Nasal cavity is a passage from the external nose anteriorly to the nasopharynx posteriorly.  The frontal, ethmoid, sphenoid and maxillary sinuses form the paired paranasal sinuses.  They are situated around and drain into the nasal cavity.  The entire complex is lined by mucus secreting epithelium.
  5. 5. + Gross Anatomy
  6. 6. + Nasal Cavity Nasal Cavity Sagittal View  Nasal Septum  Floor of the nasal cavity  Lateral wall of the cavity
  7. 7. + Nasal Cavity Lateral Wall Sagittal view  Maxillary  Palatine  Lacrimal  Ethmoid
  8. 8. + Nasal Cavity Lateral Wall Sagittal view  Sphenoethmoidal recess  Superior Turbinate  Superior Meatus  Middle turbinate  Middle meatus  Inferior turbinate  Inferior meatus
  9. 9. + Nasal Cavity Lateral wall Sagittal view  Sphenoid >> Spenoethmoidal recess.  Posterior group of ethmoid >> superior meatus.  Frontal + Ant Ethmoidal + Maxillary >> middle meatus  Nasolacrimal duct >> inferior meatus
  10. 10. + Blood Supply of Nasal Cavity  Sphenopalatine artery  Greater palatine artery  Superior labial branch of facial artery  Anterior and posterior branches of ophthalmic artery  Little’s area
