Paranasal sinus: sinuscopy

pequis

Introduction

  • Unilateral nasal discharge is often caused by disorders of the paranasal sinuses.
  • Definitive diagnosis may be provided by the clinical history and physical clinical examination.
  • More likely additional diagnostic techniques will be required such as radiography Head: radiography, nasal endoscopy Respiratory: endoscopy and centesis Paranasal sinus: percutaneous centesis and three-dimensional imaging such as computed tomography (CT).
  • Direct endoscopic examination of the sinus or sinuscopy is a useful adjunct in the evaluation of equine sinus disorders.

Uses

Advantages

  • Direct visualization of most of the structures in the paranasal sinuses.
  • Relatively non-invasive.
  • Well-tolerated in standing sedated horse.
  • Alternative to exploratory surgery Respiratory: exploratory surgery.

Disadvantages
