sinus lining instrument

The Sinus Lining Instrument is a double-ended surgical-grade stainless steel instrument with two asymmetric working ends: a 4.5mm wide blade on one end and a 5.3mm wide blade on the opposing end. Both ends carry convex dome-shaped rounded tips, visibly distinct from concave curette blade designs, set on angled shafts offset from the handle axis. The dome geometry is specifically configured for initiating the first contact with the sinus lining without applying a cutting edge against the delicate membrane tissue. The full-length ringed knurled handle provides secure grip throughout the procedure.

The two different blade widths address varying lateral window dimensions encountered across different patients. The smaller 4.5mm end enters narrower window access points, while the wider 5.3mm end covers greater membrane surface during progressive initial separation. The Schneiderian membrane elevator handle’s circumferential ring pattern maintains rotational control during the light sweeping strokes used in the initiation phase. Both ends tolerate full steam autoclave sterilization at 134°C and repeated ultrasonic cleaning without dome deformation or blade distortion.

Oral and maxillofacial surgeons and implantologists use this sinus membrane separation instrument at the start of the lateral window maxillary sinus floor augmentation procedure. Immediately after the bony window is created, the dome tip is introduced at the window margin to begin the circumferential separation of the Schneiderian membrane from the sinus floor bone. The rounded convex profile rolls under the membrane rather than cutting into it, initiating atraumatic detachment before standard curettes continue the full elevation, significantly reducing early-phase perforation risk.

When the first instrument introduced into the sinus sets the tone for the entire procedure, Leader Surgical ensures it does so with tip geometry built around protecting the membrane from the very first contact.

What instruments are used in ethmoidectomy?
The surgeon views your ethmoid sinuses with an endoscope, a thin flexible tube with a very small camera and light at the end of it. Another special instrument called a microdebrider has a tiny curved rotating tip that helps the surgeon remove tissue.
