A left\u2010sided laryngoplasty (LP) was performed by using a strand of No. 2 FiberWire and a FASTakII anchor. Phase 1 involved tightening the suture, without the DLPS device in place, in 1\u2010mm increments and acquiring a digital image of the rima glottidis at each increment. Phase 2 involved tying the suture with the DLPS in place at a left to right quotient (LRQ) of 0.7. Digital images were subsequently taken at 3 stages of DLPS activation (0, 25, and 50 or maximal psi) and analysed to calculate LRQ.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All tests were completed for 9 larynges. In phase 1, a total shortening of 25.89\u2009\u00b1\u20091.27\u2009mm was possible, which increased the LRQ from 0.59\u2009\u00b1\u20090.02 to 1.07\u2009\u00b1\u20090.12. In phase 2, activation of the DLPS increased the LRQ from 0.70\u2009\u00b1\u20090.05 to 0.97\u2009\u00b1\u20090.09. This change in LRQ equated to 18.7\u2009mm of shortening on the basis of phase 1 results.
