The 4 ¼” Antrum Trocar Needle Beveled Stylet 18G is a specialized ENT surgical instrument designed to assist with controlled access to the maxillary antrum and related sinus structures. Its long 4 ¼-inch working profile provides the reach required for procedures where a standard-length needle may not provide adequate access. The instrument is particularly suited to rhinology and sinus surgery applications where accurate positioning and controlled penetration are important.
This antrum trocar needle incorporates an 18G configuration with a beveled stylet designed to support controlled entry into the intended anatomical area. The beveled tip geometry facilitates penetration while allowing the surgeon to maintain directional control. The stylet configuration also provides a practical means of managing the working channel during the procedure.
The elongated shaft helps extend the working reach while maintaining a relatively slim profile. This makes the instrument useful when access to the maxillary sinus or antral region requires an extended approach. The design allows the instrument to be manipulated under direct visualization according to the requirements of the surgical technique.
In ENT practice, antrum trocar needles may be used during procedures involving access to the maxillary sinus, sinus drainage, diagnostic evaluation, or other techniques requiring controlled entry into the antral cavity. The specific clinical application should always follow the surgeon’s preferred technique and the intended use of the instrument.
The 18G size provides a defined working diameter suitable for procedures requiring a relatively fine access point. Combined with the 4 ¼-inch length, it offers a balance between reach and controlled handling. The beveled stylet can help provide a clean and deliberate point of entry when used appropriately.
For reusable surgical instruments, construction is typically selected for durability, resistance to repeated handling, and compatibility with established surgical instrument processing procedures. Cleaning, disinfection, inspection, and sterilization should be performed according to the manufacturer’s validated instructions and the healthcare facility’s infection-control protocols.
The 4 ¼” Antrum Trocar Needle is a useful addition to ENT, rhinology, and sinus surgery instrument collections. Its extended length, 18G configuration, and beveled stylet make it suitable for clinicians seeking a specialized instrument for controlled antral access. Proper handling and technique are essential to ensure safe and effective clinical use.
