Improved function of prototype 4.3‐mm Medtronic Quadcut microdebrider blade over standard 4.0‐mm Medtronic Tricut microdebrider blade

Abstract

The prototype blade offers faster debris and polyp removal and clogs less in the setting of allergic fungal debris. As the new blade is faster and more aggressive, introduction into a surgical setting should be guarded with an appropriate degree of caution.

Technological Innovations in Tissue Removal during Rhinologic Surgery

“…7 Other recent advancements in microdebrider blade design include blades that clog less (a significant issue with earlier iterations) and automatically close on release of the foot pedal, to reduce suctionrelated damage during removal of the instrument from the nose. 8 The tip of microdebrider blades can also now be tracked by imageguidance systems. This was initially and most simply accomplished by optical-based navigation platforms that now permit calibration using universal adapters that can be affixed to any rigid surgical instrument to enable tracking.…”

Suction modulation for the laryngeal microdebrider

“…To date, the only published method permitting the surgeon direct control of the intensity of the suction is a modification to the foot pedal that fixes the blade at the microdebrider tip into one of three fixed positions: closed (no suction), open (full suction), and halfway open (partial suction) . Suction regulators have been integral to the use of suction for medical use since its inception .…”

Sinus Penetration of Saline Solution Irrigation and Atomizer in a Cadaveric Polyp and Allergic Fungal Sinusitis Model

“… 1 Although there is evidence that demonstrate that nasal atomizers penetrate different subsites of the nose, 11 no studies have been performed to evaluate their effectiveness of sinus cavity penetration for medication delivery and possible removal of debris in an allergic fungal sinusitis (AFS) with a polyposis model. 4 , 8 , 12 Our goal was to address the ability of the nasal atomizer and manual squeeze bottle to dispense medications and/or saline solution in patients with severe, obstructive sinus disease by using a cadaveric model.…”

“…5 Multiple studies evaluated heavy sinus irrigation as a component of postoperative management after sinus surgery. [3][4][5][6][7][8][9][10] Analysis of the results of these studies indicates that sinus penetration is not only important for the removal of residual debris and postoperative crusting but also for delivery of steroids to decrease inflammation. However, it is increasingly evident that delivery system, patient anatomy, and inflammatory process all have significant impact on irrigant distribution.…”
