Hi-Fi Rigid Sinuscope 110°, Ø4mm × 175mm

Clinical Notes

Primary Clinical Applications

Highly specialized retrograde-viewing scope. Used rarely for viewing areas behind the scope tip - essentially looking backward. May be employed after creating a large opening (like a Draf III) to inspect back toward the entry point but probably most useful addressing the anterior and inferior aspects of the maxillary sinus.

Clinical Advantages

Allows visualization of areas that are otherwise completely invisible, even to 70° and 90° scopes. Provides a unique retrograde perspective that can reveal hidden pathology or anatomical details.

Ideal Procedures

Inspection after complex frontal sinus procedures to check the posterior table; examination of the anterior face of the sphenoid from inside the sinus; specialized skull base approaches.

Special Considerations

Extremely challenging to orient due to the counterintuitive retrograde view. Reserved for very specific inspection needs and rarely used for working views. Used primarily by experienced surgeons for challenging revision cases.
