Laryngeal Framework Surgery

Objective.Autologous fat injection laryngoplasty is ineffective for some patients with iatrogenic vocal fold paralysis, and additional laryngeal framework surgery is often required. An acoustically measurable outcome predictor for lipoinjection laryngoplasty would assist phonosurgeons in formulating treatment strategies.Methods.Seventeen thyroid surgery patients with unilateral vocal fold paralysis participated in this study. All subjects underwent lipoinjection laryngoplasty to treat postsurgery vocal hoarseness. After treatment, patients were assigned to success and failure groups on the basis of voice improvement. Linear prediction analysis was used to construct a new voice quality indicator, the number of irregular peaks (NIrrP). It compared with the measures used in the Multi-Dimensional Voice Program (MDVP), such as jitter (frequency perturbation) and shimmer (perturbation of amplitude).Results.By comparing the [i] vowel produced by patients before the lipoinjection laryngoplasty (AUC = 0.98, 95% CI = 0.78–0.99), NIrrP was shown to be a more accurate predictor of long-term surgical outcomes than jitter (AUC = 0.73, 95% CI = 0.47–0.91) and shimmer (AUC = 0.63, 95% CI = 0.37–0.85), as identified by the receiver operating characteristic curve.Conclusions.NIrrP measured using the LP model could be a more accurate outcome predictor than the parameters used in the MDVP.

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.
