Sinus Curette

The Sinus Curette is a double-ended surgical-grade stainless steel sinus membrane instrument with two functionally distinct working ends. One end carries a broad crescent-shaped concave blade with a wide sweeping face for covering large membrane surface areas in a single elevation stroke. The opposing end carries a 3.3mm rounded concave dome tip for accessing confined sinus floor zones and septum-adjacent regions where the wide blade cannot maintain controlled bone contact. Both ends are mounted on angled shafts offset from the full-length ringed knurled handle.

The two-geometry design allows a single instrument to address both wide membrane elevation and fine-detail separation without changing tools mid-procedure. The crescent blade’s semi-sharp concave inner face follows the sinus floor curvature through broad medial and posterior sweeping movements, while the Sinus Curette 1 SINC1 3.3mm dome end returns to targeted narrow zones for detail work around anatomical obstacles. Both working ends tolerate full steam autoclave sterilization at 134°C and standard ultrasonic cleaning without blade deformation or concavity distortion.

Oral and maxillofacial surgeons and implantologists use this Sinus Curette 1 during lateral window maxillary sinus floor augmentation after the bony access window is prepared. The crescent-shaped wide blade sweeps the Schneiderian membrane away from the sinus floor across the central, posterior, and medial wall surfaces in controlled broad strokes. The 3.3mm dome end re-addresses tight anterior wall junctions, sinus floor septa borders, and window margin zones where residual attachment points must be released before bone graft material can be packed uniformly into the elevated sub-membrane space.

When one instrument needs to do the work of two without a compromise in either blade’s geometry or performance, Leader Surgical delivers exactly that balance, purposeful design on both ends.

How do I choose the right tip angle and size?

• Angle: Specific angles (45°, 75°, 90°, or 100°) are designed to reach different anatomical recesses, such as the frontal or maxillary sinuses.
• Size: Narrow tips (2–3 mm) are best for tight spaces like the frontal recess, while wider tips (4–6 mm) provide more stability for debriding the maxillary sinus.
