The 4 ¼” Antrum Trocar Needle Beveled Stylet 14G is a specialized ENT surgical instrument designed to assist with controlled access to the maxillary antrum and related sinus structures. Its 4 ¼-inch length provides extended reach for surgical techniques where access to the antral region requires a longer working profile.
This antrum trocar needle features a 14G configuration with a beveled stylet. The beveled tip is designed to facilitate controlled entry into the intended anatomical area, while the stylet provides a practical means of managing the needle’s working passage during the procedure. The defined gauge and focused tip make the instrument suitable for techniques requiring a specific access size.
The elongated 4 ¼-inch profile allows the instrument to reach the maxillary antral region while providing the surgeon with a manageable shaft for positioning. Its slim design supports targeted access and controlled manipulation when used according to the appropriate surgical technique.
Antrum trocar needles are commonly used in ENT and rhinology settings for procedures involving access to the maxillary sinus and antral cavity. Depending on the surgical approach, an instrument of this type may be used for controlled entry, sinus access, drainage, irrigation, diagnostic procedures, or related antral techniques. Clinical use should always follow the surgeon’s selected technique and applicable medical protocols.
The 14G configuration provides a larger gauge than 16G and 18G versions, giving the instrument a correspondingly larger needle diameter. The appropriate gauge should be selected according to the specific procedure, required access, and surgeon preference. The beveled stylet helps provide a focused working tip for controlled placement.
The instrument’s straightforward design makes it suitable for inclusion in specialized ENT and sinus surgery instrument sets. Its extended shaft can be useful when working within anatomical areas where additional reach is required, while the defined needle gauge supports consistent instrument selection across different surgical procedures.
When supplied as a reusable surgical instrument, it should be appropriately cleaned and inspected after every use. Particular attention should be given to the needle and stylet to ensure that they remain free from obstruction, deformation, or visible damage. Cleaning, disinfection, and sterilization should be performed according to the manufacturer’s validated instructions and the healthcare facility’s established infection-control procedures.
The 4 ¼” Antrum Trocar Needle Beveled Stylet 14G is a practical choice for ENT, rhinology, and sinus surgery instrument collections. Its 4 ¼-inch extended length, 14G configuration, and beveled stylet provide a specialized combination of reach and controlled access for appropriate maxillary antrum procedures.
