The 4 ¼” Antrum Trocar Needle Beveled Stylet 16G is a specialized ENT surgical instrument designed to provide controlled access to the maxillary antrum and associated sinus structures. With its 4 ¼-inch length, the instrument offers extended reach for procedures where access to the antral region requires a longer working profile.
The instrument features a 16G configuration with a beveled stylet. The beveled tip is designed to support controlled entry into the intended anatomical area, while the stylet configuration allows the working passage to be managed according to the surgical technique. Its fine profile helps provide targeted access without the bulk associated with larger instruments.
The 4 ¼-inch shaft provides additional reach and helps the surgeon position the instrument appropriately during ENT and rhinology procedures. Its elongated design can be particularly useful when working toward the maxillary sinus or antral cavity from an appropriate surgical approach.
Antrum trocar needles are commonly associated with procedures involving access to the maxillary sinus, including techniques requiring controlled entry, drainage, irrigation, diagnostic access, or related sinus management. The exact clinical application depends on the procedure, patient anatomy, and surgeon’s preferred technique.
The 16G size provides a defined needle diameter for applications requiring a relatively fine access channel. Compared with larger-gauge configurations, this size may be selected when the surgical technique calls for a narrower working profile. The beveled stylet complements the instrument by providing a focused tip for controlled positioning and entry.
The instrument is designed for professional use in ENT, rhinology, and sinus surgery environments. Its straightforward configuration allows it to be incorporated into specialized ENT instrument sets alongside other sinus access, irrigation, suction, and visualization instruments.
When supplied as a reusable surgical instrument, appropriate construction and finishing are intended to support repeated clinical handling. After use, the instrument should be thoroughly cleaned and inspected, paying particular attention to the needle and stylet for blockage, deformation, or other damage. Sterilization should always 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 16G is a practical choice for surgical professionals seeking a specialized instrument for controlled maxillary antrum access. Its extended 4 ¼-inch length, 16G configuration, and beveled stylet provide a focused combination of reach and precision for appropriate ENT and rhinology applications.

FAQs
What is a 4 ¼” Antrum Trocar Needle used for?
It is designed to assist with controlled access to the maxillary antrum and sinus region during appropriate ENT and rhinology procedures.
What does 16G mean?
16G refers to the gauge size of the needle, indicating its specified diameter and working configuration.
What is the purpose of the beveled stylet?
The beveled stylet provides a focused tip designed to support controlled positioning and entry during the intended surgical technique.
Why is the antrum trocar needle 4 ¼ inches long?
The 4 ¼-inch length provides extended reach for accessing the maxillary antrum and other deeper areas during appropriate sinus procedures.
Is this instrument suitable for ENT surgery?
Yes. The instrument is designed for specialized ENT and rhinology applications involving access to the maxillary antrum and sinus region.
Can this 16G trocar needle be sterilized?
If supplied as a reusable instrument, it should be cleaned, inspected, and sterilized according to the manufacturer’s validated instructions and applicable healthcare facility protocols.
What is the difference between 16G and 18G versions?
Both are needle-gauge configurations, but 16G has a larger internal/external diameter than 18G. The appropriate size should be selected according to the surgical technique and clinical requirement.
How should the antrum trocar needle be maintained?
The instrument should be cleaned promptly after use, inspected for damage or obstruction, and processed using validated cleaning and sterilization procedures.
