Arteries of the Head and Neck01:26

Arteries of the Head and Neck

3.9K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Veins of Head and Neck

6.3K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Purpose of the Study:

  • To review the current applications of lasers in head and neck oncologic surgery.
  • To discuss the fundamental mechanisms of laser operation, focusing on the carbon dioxide (CO2) laser.
  • To analyze the role of photodynamic therapy in treating upper aerodigestive tract cancers using lasers.

Main Methods:

  • Review of current literature on laser applications in head and neck cancer surgery.
  • Explanation of basic laser principles, with emphasis on the CO2 laser.
  • Analysis of photodynamic therapy protocols and outcomes for upper aerodigestive tract cancers.

Main Results:

  • Lasers are established tools in head and neck oncologic surgery, offering precise tissue interaction.
  • The carbon dioxide (CO2) laser is a primary tool for surgical ablation and vaporization.
  • Photodynamic therapy is an evolving laser-based modality for treating cancers of the upper aerodigestive tract.

Conclusions:

  • Lasers are versatile tools in head and neck oncologic surgery, enhancing treatment options.
