Answer:

Deep Fascia of Neck Layers:

• Investing layer
• Pretracheal layer
• Prevertebral layer
• Carotid sheath
• Buccopharyngeal fascia
• Pharyngobasilar fascia

Deep Fascia of Neck Layers:

Deep Fascia of Neck Layers Applied Anatomy:

1. Investing Layer:
   • Parotid swellings are very painful due to the unyielding nature of parotid fascia
2. Supraclavicular Space:
   • It is pierced by the external jugular vein to drain into subclavian vein
   • Division of external jugular vein may cause air embolism
3. Pretracheal Fascia:
   • The thyroid gland & all thyroid swellings move with deglutition because the thyroid is attached to the larynx by the suspensory ligament of Berry
   • Neck infections in front of it may bulge in the suprasternal area or extend down into the anterior mediastinum
4. Prevertebral Fascia:
   • Neck infections behind it arise usually from tuberculosis of the cervical vertebrae or cervical caries
   • The pus formed may travel

• • 1. Forward resulting in chronic retropharyngeal abscess in posterior wall of pharynx
    2. Laterally into posterior triangle through the axillary sheath
    3. Downward into superior mediastinum
  • Neck infections in front of it usually arise from retropharyngeal lymph nodes resulting in acute retropharyngeal abscess
