Respiratory: exploratory surgery

Contributor(s): Carl Kirker-Head, Graham Munroe

Introduction

  • To visually or palpably assess components of the respiratory tract as a means of facilitating diagnosis or management of disease and injury after all other means have been used.

Uses

  • The proliferation of endoscopic   Respiratory: endoscopy  and advanced imaging techniques including radiographic, ultrasonographic, scintigraphic, computed tomographic and magnetic resonance imaging   Magnetic resonance imaging  has curtailed the need for purely exploratory respiratory surgery.
  • Principal indications are the exclusion or confirmation of presumptive diagnosis.
  • The parasnasal sinuses remain the most common surgically explored respiratory structures, although the nasal meati, pharynx, larynx and thoracic cavity occasionally require surgical exploration.

Advantages

  • Allows direct visualization and palpation of otherwise inaccessible structures.
  • Some procedures cxan be carried out in the standing horse, eg paranasal sinus trephination   Head: trephination  .

Disadvantages

  • Predisposes to potentially serious complications, eg hemorrhage, pneumothorax   Pneumothorax  .
  • Surgery of the respiratory tract implies a clean-contaminated environment and hence the potential for wound infection.
