Cannulae, Nasal, Sinus
Definition : Nasal cannulae designed to be inserted into the nostrils until the distal tip reaches one of the nasal sinuses. These cannulae are typically short, rigid or semirigid, plastic or, less frequently, metal tubes that may include a stylet (i.e., the combination of cannula and stylet is known as a trocar) that is usually removed after insertion; they are frequently connected directly or via an external tube or catheter to an irrigator and/or aspirator for irrigation, infusion, or withdrawal of substances. Nasal sinus cannulae may also provide a port through which instruments and/or probes are passed to perform a variety of diagnostic, treatment, or surgical procedures.
