Quantitative laryngeal electromyography (LEMG) in unilateral vocal fold paralysis: Developing normative values using the opposite normal mobile vocal fold.

Objective: Laryngeal electromyography (LEMG) is used to confirm neuropathy; traditionally, it is evaluated qualitatively. This study aimed to develop normative values for the thyroarytenoid-lateral cricoarytenoid (TA-LCA) muscle complex by determining the mean turns (MT) and mean amplitudes (MA) using the opposite normal mobile vocal fold in unilateral vocal fold paralysis (VFP). This study also compared the MT and MA of the paralyzed vocal fold with that of the normal side and analyzed their correlations.

Nonselective Laryngeal Reinnervation versus Type 1 Thyroplasty in Patients with Unilateral Vocal Fold Paralysis: A Single Tertiary Centre Experience.

Objective: This study compared the voice outcomes of selected patients with unilateral vocal fold palsy (UVFP) who underwent either nonselective laryngeal reinnervation (LR) or Type 1 thyroplasty (thyroplasty) in a Malaysian tertiary centre using multidimensional voice assessments.

Participants: The study included 16 patients with UVFP who underwent either LR (9 patients) or thyroplasty (7 patients) between 2015 and 2018 who fulfilled the inclusion criteria.

Main Outcome Measures: The outcomes were measured subjectively and objectively with: (1) voice handicap index-10 (VHI-10- Malay version); (2) auditory perceptual evaluation using the breathiness component of Grade, Roughness, Breathiness, Asthenia, Strain scale; (3) maximum phonation time (MPT); and (4) acoustic analysis (jitter%, shimmer%, and NHR) using OperaVOX.

Chondrogenesis of human adipose derived stem cells for future microtia repair using co-culture technique.

Conclusion: In conclusion, these result showed HADSCs could differentiate into chondrocytes-like cells, dependent on signaling induced by TGF-β3 and chondrocytes. This is a promising result and showed that HADSCs is a potential source for future microtia repair. The technique of co-culture is a positive way forward to assist the microtia tissue.
