Unilateral Vocal Cord Paralysis

Vocal cord paralysis in children is an uncommon but often disabling problem. It may be congenital or acquired either in the immediate period surrounding birth or as a postpartum event. Because even unilateral vocal cord paralysis can result in severe respiratory distress in the newborn and in small children, recognition of this problem can be critical. A logical approach to diagnosis and management requires not only that the physician be alert to the problem but also that several procedures be established that can be used together or singly to address the problem, as is most appropriate to the individual case. The usefulness of intubation, tracheotomy, surgical lateralization of the vocal folds, and reinnervation in the management of these problems is discussed, and 30 cases of vocal cord paralysis in children under the age of 5 years are presented.

Unilateral Vocal Cord Paralysis

This paper investigates the effectiveness of measures related to vocal tract characteristics in classifying normal and pathological speech. Unlike conventional approaches that mainly focus on features related to the vocal source, vocal tract characteristics are examined to determine if interaction effects between vocal folds and the vocal tract can be used to detect pathological speech. Especially, this paper examines features related to formant frequencies to see if vocal tract characteristics are affected by the nature of the vocal fold-related pathology. To test this hypothesis, stationary fragments of vowel /aa/ produced by 223 normal subjects, 472 vocal fold polyp subjects, and 195 unilateral vocal cord paralysis subjects are analyzed. Based on the acoustic-articulatory relationships, phonation for pathological subjects is found to be associated with measures correlated with a raised tongue body or an advanced tongue root. Vocal tract-related features are also found to be statistically significant from the Kruskal-Wallis test in distinguishing normal and pathological speech. Classification results demonstrate that combining the formant measurements with vocal fold-related features results in improved performance in differentiating vocal pathologies including vocal polyps and unilateral vocal cord paralysis, which suggests that measures related to vocal tract characteristics may provide additional information in diagnosing vocal disorders.

Unilateral Vocal Cord Paralysis

Five cases of unilateral vocal cord paralysis/ paresis were diagnosed following extracorporeal membrane oxygenation for newborn respiratory failure. All were right sided and transient in nature. None of the five patients had other findings commonly associated with vocal cord palsy. The extracorporeal membrane oxygenation procedure requires surgical dissection in the carotid sheath on the right side of the neck, an area immediately adjacent to both the vagus and recurrent laryngeal nerve. It is speculated that vocal cord paralysis in these infants was acquired as a result of the extracorporeal membrane oxygenation cannulation. Although the vocal cord paralysis resolved in all cases, two patients had difficult courses after extracorporeal membrane oxygenation. Therefore, laryngoscopic examination should be considered for patients after extracorporeal membrane oxygenation.

Unilateral Vocal Cord Paralysis

<p class="abstract"><strong>Background:</strong> Vocal cord paralysis is a clinical sign caused by paralysis of intrinsic muscles of larynx due to dysfunction of recurrent laryngeal nerve. There are several methods available surgically for the medialisation of the abducted vocal cord. One of the common effective modality is the Gore-Tex medialisation thyroplasty. The results depend on a number of factors including the surgical expertise and extrusion of the Gore –Tex implant. This study is aimed at analysis of all Gore-Tex medialisation thyroplasty done at our centre. Prospectively asses and analyze the vocal outcomes and quality of life of patients in type 1 medialisation thyroplasty using Gore-Tex implant.</p><p class="abstract"><strong>Methods:</strong> Prospective study of 48 months on 30 patients with unilateral vocal cord paralysis.  Surgical procedure for the patients was standardized by using Gore-Tex implant to medialize the cord. Video-Laryngoscopy at end of 1<sup>st</sup> month and stroboscopy &amp; voice analysis at end of 3<sup>rd</sup> month post treatment, the parameters used for the pre and post treatment objective analysis are a) stroboscopic analysis, b) psychoacoustic evaluation, c) maximum phonation time, d) patient’s self-assessment.  </p><p class="abstract"><strong>Results:</strong> In our study of 30 patients with a follow up period of 48 months, we can conclude as follows – a)unilateral vocal cord paralysis does not have age or gender specificity, b)statistically significant vocal cord palsy affects the left side more by 70%, c)post op Gore-tex medialisation thyroplasty showed a statistically highly significant improvement in psychoacoustic, mean phonation time, d)post op Gore-Tex medialisation thyroplasty showed a statistically significant improvement in videostroboscopic analysis.</p><p><strong>Conclusions:</strong> Psycho acoustic, mean phonation time analysis would complement each other in the assessment of the medialisation thyroplasty thus obviating videostroboscopy.</p>
