Stammberger Antrum Punches PS-5286 for 10.5-12cm Maxillary Antrum Access

Stammberger Antrum Punches SKU PS-O T-01476, model PS-5286, are reusable ENT punch instruments manufactured from German stainless steel for controlled maxillary antrum access and ostial margin enlargement during endoscopic sinus surgery. The variants include PS-5286 right side working length 4-1/8 inch (10.5cm), PS-5286 slender left side working length 4-3/4 inch (12cm), PS-5286 slender right side working length 4-3/4 inch (12cm), PS-5286 slender upside-down working length 4-3/4 inch (12cm), PS-5286 upside-down working length 4-1/8 inch (10.5cm), and PS-5286 left side working length 4-1/4 inch (10.7cm). These punches are used in functional endoscopic sinus surgery, maxillary antrostomy, uncinate-related access refinement, revision sinus surgery, antral window enlargement, and removal of obstructing bony or mucosal margins. ENT surgeons, rhinologists, otolaryngology teams, hospitals, ambulatory surgery centers, and sinus clinics select these directional patterns for controlled access within narrow nasal corridors.

Directed Punch Geometry for Antral Access

Stammberger Antrum Punches use a long shaft, angled distal jaw, and ring-handle actuation to deliver a controlled bite at the maxillary antrum while the surgeon keeps the hand outside the endoscopic field. The jaw orientation is built for side-specific and upside-down access, allowing the cutting edge to face the target margin without excessive rotation of the entire instrument. The shaft provides reach through the middle meatus, while the distal cup profile captures a defined tissue or bony edge before the handle is compressed. The pivoted handle transfers closing force through the shaft into the punch jaw, producing a measured bite rather than a traction-based tear. The ring handles support stable finger placement during repeated incremental cuts. Slender variants reduce profile bulk in confined nasal anatomy and revision corridors. This mechanism is valuable when the surgeon needs to enlarge the natural ostium, refine a created antrostomy, or trim obstructing antral margins under endoscopic visualization.

FESS Workflow and Maxillary Sinus Entry

During functional endoscopic sinus surgery, these antrum punches are used after visualization of the middle meatus, mobilization or removal of the uncinate process, and identification of the maxillary ostium. The working jaw is placed against the posterior fontanelle, antral margin, or selected edge of the antrostomy. The surgeon closes the handle to remove small controlled segments, then repositions the jaw for sequential enlargement. In primary maxillary antrostomy, the punch helps create a defined opening with directional control around the natural drainage pathway. In revision procedures, the instrument assists removal of residual bony shelves, fibrotic margins, or obstructive tissue that narrows the sinus entry. Side-specific patterns allow approach from the right or left nasal cavity without forcing the wrist into an awkward position. Upside-down variants support inferior or reverse-angle bites where a standard side jaw cannot align cleanly with the target edge.

Variant Selection by Side and Working Length

The right side 4-1/8 inch (10.5cm) pattern is selected for right-sided maxillary antrum access when a compact working length is preferred. The left side 4-1/4 inch (10.7cm) pattern provides mirrored directional alignment for left nasal cavity work. The slender left side 4-3/4 inch (12cm) variant gives additional reach with a reduced distal profile for narrow middle meatal access and revision anatomy. The slender right side 4-3/4 inch (12cm) version serves the same purpose on the opposite side, particularly when deeper antral margins require a longer shaft. The slender upside-down 4-3/4 inch (12cm) pattern is useful for reverse-angle trimming at deeper or inferior margins. The upside-down 4-1/8 inch (10.5cm) option supports compact reverse orientation when the surgical field does not require extended reach. Selection depends on operative side, access depth, jaw orientation, patient anatomy, and the planned enlargement of the maxillary sinus opening.

Steel Finish, Reprocessing, and Supply Terms

German stainless steel construction gives these antrum punches the rigidity needed for long-shaft ENT work and repeated punch action at bony or fibrotic antral margins. The reusable design supports integration into FESS trays, rhinology sets, and hospital sinus surgery inventories. Satin, dull, or mirror finish options support visual inspection after cleaning and reduce avoidable glare under endoscopic lighting. Standard reprocessing includes cleaning of the distal jaw, shaft, pivot, and ring handles before autoclave sterilization according to facility protocol. The instrument is listed as Class I and supports CE, ISO 13485, and FDA procurement documentation for hospitals, clinics, and distributors managing regulated purchasing. MOQ is 1 piece, which allows single-pattern replacement without ordering a full set. OEM availability supports institutional sourcing and distributor supply programs. Return and replacement after-sale service with a 1-year warranty gives procurement teams clear commercial terms for operating room stock control.

How are Stammberger Antrum Punches different from Blakesley nasal forceps?
Blakesley nasal forceps are mainly used to grasp and remove soft tissue fragments during endoscopic nasal work. Stammberger Antrum Punches are designed to take controlled bites from the maxillary antrum margin. Their side-specific and upside-down jaw orientations allow a more directed cutting angle than a straight grasping forceps. The punch jaw captures a defined edge before closure, while Blakesley jaws depend more on grasping and extraction. Stammberger Antrum Punches are therefore better suited for antrostomy margin enlargement and bony shelf trimming. In FESS workflow, both instruments can be used, but their mechanical roles are different.

Which Stammberger Antrum Punches variant is selected for right, left, or upside-down access?
The right side 10.5cm pattern is selected when the surgeon needs compact access on the right maxillary antrum. The left side 10.7cm pattern mirrors that access for left nasal cavity work. Slender right and slender left 12cm variants are selected when a longer reach and reduced shaft profile are needed. The slender upside-down 12cm pattern helps address deeper reverse-angle margins during revision or extended FESS. The upside-down 10.5cm variant is useful when reverse orientation is needed but the field does not require the longer working length. Stammberger Antrum Punches are selected according to operative side, antral edge position, access depth, and endoscopic viewing angle.

Do these instruments support CE, ISO 13485, and FDA procurement requirements?
Yes, Stammberger Antrum Punches are listed with CE, ISO 13485, and FDA procurement support. CE marking assists facilities that require conformity documentation for surgical instrument purchasing. ISO 13485 alignment supports medical device quality management expectations for manufacturing and supply. FDA procurement support helps hospitals, clinics, and distributors maintain regulated vendor records. The product is listed as a Class I reusable surgical instrument. These details are important for operating room procurement, distributor onboarding, and institutional ENT tray planning.

How does the pivot and ring-handle mechanism control the punch action?
The pivot converts ring-handle compression into closing force at the distal punch jaw. This lets the surgeon position the working end on the antral margin before applying a measured bite. The ring handles provide stable finger control during repeated cuts inside the middle meatus. The long shaft transfers movement from the handle to the cutting end while keeping the operator's hand outside the nasal field. Stammberger Antrum Punches rely on this mechanism to remove small segments without broad instrument sweep. The design supports controlled enlargement of the maxillary ostium under endoscopic visualization.

Are Stammberger Antrum Punches suitable for hospital sterilization and distributor supply?
Stammberger Antrum Punches are reusable and intended for standard surgical instrument reprocessing. Sterile processing teams can clean the jaw, shaft, pivot, and handles before autoclave sterilization according to facility protocol. German stainless steel construction supports repeated use in ENT operating room trays. The MOQ of 1 piece allows hospitals and clinics to replace a single direction pattern as needed. OEM availability supports distributor-managed supply programs and institutional sourcing. The 1-year warranty with return and replacement service gives purchasing teams clear terms for inventory management.
