Summary

Severe epistaxis (nosebleeds) can be effectively treated surgically by understanding nasal arterial anatomy and collateral circulation. Microsurgery and endoscopy offer successful outcomes for complex cases.

Area of Science:

  • Otorhinolaryngology (ENT)
  • Head and Neck Surgery
  • Anatomy and Physiology

Context:

  • Severe epistaxis presents significant clinical challenges, often requiring surgical intervention.
  • Existing anatomical descriptions of nasal arterial supply may not fully account for surgical outcomes.
  • Understanding collateral circulation is crucial for managing persistent or recurrent nosebleeds.

Purpose:

  • To review the surgical treatment options for severe epistaxis.
  • To describe the detailed arterial anatomy of the nasal cavities, including variations.
  • To analyze surgical outcomes based on anatomical understanding and specific arterial ligations.

Summary:

  • The study details nasal arterial anatomy, highlighting two main arterial branches from the sphenopalatine foramen and two key anastomotic systems.

  • Surgical indications include severe bleeding unresponsive to packing or with associated complications.
  • Results from 31 procedures (8 upper, 23 posterior epistaxis) show high success rates with targeted ligations of ethmoid, lateral-posterior nasal, and nasoseptal arteries.

    • Impact:

    • Accurate anatomical knowledge and understanding of collateral circulation improve surgical success rates for severe epistaxis.
    • Microsurgery and transnasal endoscopy are effective tools for managing complex nasal bleeding.
    • This research refines surgical strategies by emphasizing detailed vascular architecture of the paranasal sinuses.
