Abstract
INTRODUCTION: Unilateral vocal fold paralysis (UVFP) was a relative common glottic insufficiency disease; however, a completely satisfactory treatment of UVFP was elusive. This study was aimed to evaluate the surgical efficacy of modified arytenoid adduction with fenestration of the thyroid cartilage in the management of patients with UVFP, including voice and aspiration outcomes, and to summarize the postoperative complications. METHODS: A retrospective analysis was performed on a total of 21 patients who underwent modified arytenoid adduction operation with fenestration of the thyroid cartilage for UVFP from July 2012 to June 2017. The scores of Grade, Roughness, Breathiness, Asthenia, Strain scale (GRBAS), voice self-satisfaction, dynamic laryngoscopy and the voice acoustic data (fundamental frequency [F0], fundamental frequency perturbation [jitter], loudness, amplitude perturbation [shimmer], and maximal phonatory time [MPT], etc.) were statistically analyzed preoperatively and 3-6 months postoperatively. The occurrence of postoperative complications was also summarized. RESULTS: The voice subjective perception of 21 patients was significantly improved after operation. The rate of voice self-satisfaction was 90.5%. The mean values of voice acoustics parameters were significantly improved. The MPT was significantly longer (p < 0.001), and the ratings of postoperative aspiration were significantly decreased compared with the preoperation. Among the 21 patients, 15 cases had sense of laryngeal obstruction, 8 cases had of 1-2° laryngemphraxis (recovered after 10-15 days). There were 2 cases of laryngeal stridor, 1 case of incision infection, 1 case of pharyngeal fistula, and 1 case of falsetto (corrected by voice training). No patient had laryngeal hematoma, neck hematoma, or laryngospasm. CONCLUSION: The modified arytenoid adduction operation with fenestration of the thyroid cartilage can significantly improve the vocal function of patients with UVFP and effectively reduce the aspiration, with fewer postoperative complications, less trauma, and more convenient advantages.
