A left\u2010sided laryngoplasty was performed with No. 2 Fiberwire and a FASTakII anchor. Each larynx was tested in a static airflow model. The system was adjusted to a flow rate of 55\u2009L\/s and prelaryngeal pressure of 12\u2009mm Hg prior to testing in maximal arytenoid abduction. In phase 1, the left suture was loosened, shortened, and tested in 3\u2010mm steps from 0 to 30\u2009mm. In phase 2, the suture was tied with the DLPS in position at a target left\u2010to\u2010right quotient angle (LRQ) of 0.5. The DLPS was activated to target psi of 0, 25, and 50 for testing.
