Epistaxis01:30

Epistaxis

267
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Area of Science:

  • Neurosurgery
  • Surgical Techniques

Background:

  • Skull base surgery necessitates precise hemostasis and dissection for optimal outcomes.
  • Challenges in managing intraoperative bleeding and achieving accurate tissue planes are common.

Purpose of the Study:

  • To present novel hemostasis and dissection techniques for skull base surgery.
  • To enhance surgical precision and bleeding control in complex cranial procedures.

Main Methods:

  • Description of specialized hemostasis techniques utilizing fibrin glue-soaked hemostatic fabric.
  • Introduction of Gore-Tex patching for managing specific bleeding scenarios.
  • Application of semi-sharp dissection with SS forceps for meticulous dissection.

Main Results:

  • These techniques facilitate prompt identification and control of bleeding points.
  • Improved accuracy in dissection is achieved through the described methods.
  • The combination of techniques offers versatility in managing diverse surgical challenges.

Conclusions:

  • The presented hemostasis and dissection strategies contribute to safer and more effective skull base surgery.
  • Fibrin glue, Gore-Tex patching, and specialized forceps dissection represent valuable adjuncts for neurosurgeons.
