?:definition
  • Instruments designed to puncture the wall of any of the paranasal sinuses (i.e., frontal, ethmoid, and maxillary antrum). These instruments typically consist of a manual, handheld instrument with a strong sharp pyramidal or conical, either straight or curved, pointed rod and a proximal large handle. Antrum trocars are usually fitted into a metallic cannula. The trocar is used to pierce the skin and the wall of the antrum and then it is usually removed, leaving the cannula in place. Antrum trocars are intended to provide access to the nasal sinuses to permit the aspiration of fluids, to instill medications, or to provide access for diagnostic, therapeutic, and/or surgical devices.
