title: Perioperative complications and safety of type II thyroplasty (TPII) for adductor spasmodic dysphonia.
abstract: Type II thyroplasty (TPII) is one of the surgical options offered in the management of adductor spasmodic dysphonia (AdSD); however, there have been no detailed reports of its safety and associated complications during the perioperative period. Our aim was to assess the complications and safety of TPII. TPII was performed for consecutive 15 patients with AdSD from April 2012 through May 2014. We examined retrospectively the perioperative complications, the degree of surgical invasion, and recovery process from surgery. All patients underwent successful surgery under only local anesthesia. Vocal fold erythema was observed in 14 patients and vocal fold edema in 10 patients; however, all of them showed complete resolution within 1 month. No patient experienced severe complications such as acute airway distress or hemorrhage. Fourteen patients were able to have oral from the 1st postoperative morning, with the remaining patient able to have oral intake from the 2nd postoperative day. In addition, no patient experienced aspiration postoperatively. In conclusion, only minor complications were observed in association with TPII in this study. No dysphagia was observed postoperatively, which is an advantage over other treatments. The results of our study suggest that TPII is a safe surgical treatment for AdSD.
