Bottom Line: Different treatments are available for the management of UVFP including intracordal injection, type I thyroplasty, arytenoid adduction, and laryngeal reinnervations.All subjects experienced postoperative improvements in voice quality.Immediate RLN reconstruction has the potential to restore a normal or near-normal voice by returning thyroarytenoid muscle tone and bulk seen with vocal fold denervation.

ABSTRACT
Unilateral vocal fold paralysis (UVFP) is one of the most serious problems in conducting surgery for thyroid cancer. Different treatments are available for the management of UVFP including intracordal injection, type I thyroplasty, arytenoid adduction, and laryngeal reinnervations. The effects of immediate recurrent laryngeal nerve (RLN) reconstruction during thyroid cancer surgery with or without UVFP before the surgery were evaluated with videostroboscopic, aerodynamic, and perceptual analyses. All subjects experienced postoperative improvements in voice quality. Particularly, aerodynamic analysis showed that the values for all patients entered normal ranges in both patients with and without UVFP before surgery. Immediate RLN reconstruction has the potential to restore a normal or near-normal voice by returning thyroarytenoid muscle tone and bulk seen with vocal fold denervation. Immediate RLN reconstruction is an efficient and effective approach to the management of RLN resection during surgery for thyroid cancer.

Mentions: Normal speakers usually have an MPT of more than 10 seconds and an MFR between 100 ml/sec and 200 ml/sec. The postoperative recordings of MPT (16.2 sec ± 6.2) in group I were significantly greater than the preoperative levels (7.1 sec ± 2.55). The postoperative MFR (110.3 ml/sec ± 38.4) in group I was significantly reduced compared with the preoperative levels (271 ml/sec ± 325.1) (Figure 2). In group II, three of the 6 patients did not receive a preoperative examination. Therefore, it was not possible to make a statistical comparison of preoperative and postoperative data. However, the postoperative results of MPT and MFR showed that patients' voices were returned to a normal condition. There were no significant differences between the postoperative data of both groups (Figure 2).
