The Voice

Objective. To objectively assess the voice outcomes of patients with unilateral vocal fold paralysis treated with medialization thyroplasty and arytenoid adduction suture. Study Design. Case series of patients who underwent medialization thyroplasty and arytenoid adduction suture. Preoperative and postoperative voice testing was performed and the data were compared by statistical analysis. Setting. Tertiary referral teaching hospital in Sydney, Australia. Subjects. All patients had a unilateral vocal fold paralysis, with a large posterior glottic gap and vocal symptoms affecting their quality of life. Methods. Thirteen patients with a diagnosis of a unilateral vocal fold paralysis with a large posterior glottic gap, vocal symptoms, and total denervation of the vocal fold underwent medialization thyroplasty and arytenoid adduction suture. The surgery was performed in a novel method under a general anesthetic using a laryngeal mask and with direct intraoperative endoscopic feedback. Preoperative and postoperative measures of voice performance were compared, including acoustic analysis (fundamental frequency, speech intensity against quiet and loud background noise, speech rate) and aerodynamic assessment (airflow, maximum phonation time). Results. Medialization thyroplasty with arytenoid adduction suture significantly improved aerodynamic assessment and phonation duration for both male and female subjects overall. There were 2 of 13 treatment failures. Median follow-up time was 6 months. Conclusion. Preliminary results indicate that in selected patients with vocal fold paralysis, medialization thyroplasty with arytenoid adduction suture leads to significant improvements in objective voice measures. Longer follow-up data are required to further quantify the voice outcomes after this procedure.

Perceptual Evaluation

The objective of this study was to evaluate the effects on voice quality of augmentation by injection of minced fascia in patients with unilateral vocal fold paralysis. Preoperative and postoperative voice samples from 14 patients (6 men and 8 women; mean age, 59 years) were analyzed by computerized acoustic analysis and blinded perceptual evaluation. Statistically significant improvements were seen in perturbation measurements (jitter and shimmer), noise-to-harmonics ratio, and maximum phonation time. A panel of evaluators rated 10 of the 14 postoperative voices as normal or near-normal. Injection laryngoplasty with minced fascia offers a new, effective, well-tolerated, and inexpensive method to medialize a paralyzed vocal fold. The graft seems to survive well, as indicated by good vocal results with a follow-up ranging from 5 to 32 months.

Fat Volume

This study evaluates the efficacy of autologous fat injection for medialization of the paralyzed vocal fold. In 21 patients with unilateral vocal fold paralysis, autologous abdominal fat was injected into the thyroarytenoid muscle to achieve medialization. All patients were followed up with serial videolaryngoscopy and voice evaluation. At 2 months' follow-up, the voice was judged to be excellent in 10 patients, slightly breathy but significantly better than the preoperative voice in 6 patients, and markedly breathy in 4 patients. At 3 to 4 months' follow-up, of the 10 patients with excellent results, 5 maintained an excellent voice, 3 had developed slight breathiness, and 1 had developed severe breathiness. Long-term (6 to 12 months) results were available in 11 patients, and all of them maintained the same voice quality that was noted during the 3 to 4 months' examination. Magnetic resonance imaging of the larynx was obtained in 7 patients at intervals ranging from 1 to 7 months and compared to the baseline scan obtained at 1 week postoperative to assess the amount of fat remaining in the muscle. The images showed fat volume to persist, but a decrease in the fat signal was observed over time. The results suggest that the duration of medialization with autologous fat is variable, but appears to last at least 2 to 3 months. This loss of volume after 3 months seems to be due to absorption of the fat and possibly muscle atrophy. Autologous fat injection is relatively safe and easy to perform, and is an ideal method of temporary vocal fold medialization in patients in whom return of vocal fold function is expected.

Type I Thyroplasty

Between 1995 and 1997, we performed Isshiki's original method of arytenoid adduction alone or as an adjunct to type I thyroplasty for the treatment of unilateral vocal fold paralysis. From 1997 onward, we performed arytenoid adduction by traction of the lateral cricoarytenoid muscle (Iwamura's method), because it reduces discomfort to the patient and avoids rotation of the thyroid cartilage. Preliminary experiments and surgical procedures involving traction of the lateral cricoarytenoid muscle are described. Of 21 patients with a maximum phonation time of less than 9 seconds, 14 underwent type I thyroplasty as an adjunct to our method of arytenoid adduction and 7 underwent arytenoid adduction alone. Sixteen patients (76%) were able after surgery to extend their maximum phonation time beyond 10 seconds; this result compares favorably with the results of Isshiki's original adduction technique. We describe useful anatomic landmarks for approaching the lateral cricoarytenoid muscle in the hope that more voice surgeons will adopt this approach in the treatment of unilateral vocal fold paralysis.

<b><i>Introduction:</i></b> 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. <b><i>Methods:</i></b> 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. <b><i>Results:</i></b> 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 (<i>p</i> &#x3c; 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. <b><i>Conclusion:</i></b> 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.
