Laryngeal Electromyography-Guided Hyaluronic Acid Vocal Fold Injection for Unilateral Vocal Fold Paralysis—Preliminary Results

LEMG-guided HA VFI provides UVFP patients with neuromuscular function evaluation and treatment in one step. This clinical technique is feasible, and the short-term results are satisfactory.

Arytenoid rotation and nerve-muscle pedicle transfer in paralytic dysphonia

AA + modified NMP improves both short- and long-term voice outcomes in unilateral vocal fold paralysis patients. Therefore, AA + modified NMP is an effective surgical combination for the treatment of severe paralytic dysphonia.

Subjective Breathing Impairment in Unilateral Vocal Fold Paralysis

Discussion: Our study revealed a certain discrepancy between objectively assessed laryngoscopic findings and subjective symptoms. A majority of patients suffered from an impairment in each of the three laryngeal functions (dysphonia, dysphagia and dyspnea). The latter two differ from the classic approach to this condition but must be considered as well in clinical diagnostics and therapy.

Evaluation of Stroboscopic Signs

The results of the study support the concept that a small set of stroboscopic ratings is an adequate representation of the information derived from the original, more comprehensive sign rating protocol. A focused rating system may provide an efficient method for stroboscopic evaluation, contributing to the differentiation of various vocal fold pathologies and correlating to clinician ratings of severity of dysphonia.

Medialization thyroplasty: vocal outcome of silicone and titanium implant

Unilateral vocal fold paralysis can result in incomplete glottic closure, compromising the vocal efficiency and increasing the risk of aspiration. The glottic gap can be reduced by medialization thyroplasty. Both silicone and titanium implants have been described to be efficient in the improvement of the vocal outcome. The aim of this study was to assess the vocal outcome after medialization thyroplasty using silicone and titanium implants and to compare the results of the two implanted materials using prospective sequential cohort study. 24 patients underwent medialization thyroplasty, performed under local anaesthesia with intravenous sedation: 10 patients were included in the silicone cohort and 14 in the titanium cohort. All patients underwent vocal assessment preoperatively and postoperatively, using the Voice Handicap Index, the GRBASI scale, maximum phonation time and the Dysphonia Severity Index. Postoperative analysis of the entire population showed statistically significant improvement for the Voice Handicap Index, maximum phonation time, Dysphonia Severity Index and the parameters G, B and A of the GRBASI scale (83% follow up). Subgroup analysis showed a statistically significant greater improvement of Voice Handicap Index of the titanium cohort compared with the silicone cohort. Improvement of maximum phonation time, Dysphonia Severity Index and GRBASI scale of the titanium cohort was greater than improvement of the silicone cohort, but this difference was not statistically significant. Both silicone and titanium medialization implants showed improvement of vocal outcome, the results of the titanium implant being superior.
