Abductor Paralysis

It is known that abductor paralysis (AP) of the vocal folds sometimes occurs in patients with multiple system atrophy (MSA), and some of them have sleep apnea and loud snoring during sleep. However, the site of obstruction and the sound source of the snoring are still unknown. We performed fiberscopic examinations under diazepam sedation in 8 MSA patients with AP and analyzed the snoring sound. We found that the peculiar snoring occurred with inspiratory vibration of the vocal folds, and there was no obstruction in this portion. Acoustic analysis showed that the fundamental frequency of vocal fold snoring was 260 to 330 Hz, which is different from that of ordinary soft palate snoring. Recognition of vocal fold snoring is important in the early diagnosis of MSA and sleep-related breathing disorders.

AbstractA patient is presented who had bilateral abductor vocal fold paralysis pathologically proven to be due to multiple system atrophy (MSA) in the absence of other neurological features. MSA is a degenerative neurological condition that includes olivopontocerebellar atrophy, Shy-Drager syndrome and striatonigral degeneration. The usual predominant features of MSA are cerebellar ataxia, autonomic dysfunction and Parkinsonism. Stridor is present in over one third of patients and has been reported previously as a presenting symptom in MSA: however previously reported patients have always gone on to develop other neurological symptoms. The usual investigations of bilateral abductor vocal fold paralysis caused by MSA will not reveal the pathological process and we believe that magnetic resonance imaging (MRI) of the medulla and brain stem and autonomic function tests are probably the investigations of choice. It is a worthwhile exercise attempting to identify MSA as the cause of stridor as the prognosis is good in the medium term if appropriate support is offered.

Injectable bovine collagen has been used for treatment of glottic insufficiency at the University of Wisconsin Clinical Science Center since 1983. This report reviews our experience in treating 119 patients with a variety of vocal fold disorders manifested by glottic insufficiency. Many of the patients were referred because of prior treatment failures or problems that were impossible to treat with other modalities. Results were assessed by comprehensive voice evaluations using subjective patient self-assessments, perceptual judgments made by a panel of experts who had no prior knowledge of the study, objective assessments, and videostroboscopy. Objective assessment included vocal function measures and acoustic analysis. Results indicate that collagen not only is comparable to other injection filler substances but also has unique advantages as a bioimplant. Collagen injection seems uniquely suited for treatment of several problems, including vocal fold atrophy, focal defects, minimal glottic insufficiency, and scarred vocal folds that are not managed optimally with Teflon injection. Overall there were no serious complications and treatment was effective for a broad spectrum of problems. In most instances the correction persisted, and in those instances in which injected collagen seemed improperly distributed, the vocal fold was recontoured or the implant removed without appreciable damage to the surrounding tissues. Injectable collagen has been extensively studied and deserves to be included in the armamentarium of the laryngeal surgeon.

AbstractThe case of an elderly male with Shy-Drager syndrome is presented. His presentation to the Sleep Clinic for assessment of snoring illustrates bilateral abductor vocal fold palsy as a rare presentation of the syndrome. This case emphasizes the need for thorough investigation of all patients with sleep-related breathing disorders with video and sound recordings prior to anaesthesia and surgery.

AbstractObjective:To investigate the short term effect of hubble-bubble smoking on voice.Study design:Prospective study.Material:Eighteen non-dysphonic subjects (seven men and 11 women) with a history of hubble-bubble smoking and no history of cigarette smoking underwent acoustic analysis and laryngeal video-stroboscopic examination before and 30 minutes after hubble-bubble smoking.Results:On laryngeal video-stroboscopy, none of the subjects had vocal fold erythema either before or after smoking. Five patients had mild vocal fold oedema both before and after smoking. After smoking, there was a slight increase in the number of subjects with thick mucus between the vocal folds (six, vs four before smoking) and with vocal fold vessel dilation (two, vs one before smoking). Acoustic analysis indicated a drop in habitual pitch, fundamental frequency and voice turbulence index after smoking, and an increase in noise-to-harmonics ratio.Conclusion:Even 30 minutes of hubble-bubble smoking can cause a drop in vocal pitch and an increase in laryngeal secretions and vocal fold vasodilation.

Objectives. The purpose of this study was to quantify the size of vocal fold polyps and to investigate the relationship between the glottal gap and parameters of acoustic voice analysis and phonetography. Material and methods. Eighty-one microlaryngoscopic images and digital recordings of voices (acoustic analysis and phonetogram) acquired from the patients with vocal fold polyps (VFPs) were employed in this study. Vocal fold (VF) images were collected during routine direct microlaryngoscopy using Moller-Wedel Universa 300 surgical microscope, 3-CCD Elmo 768×576- pixel color video camera and a 300 W Xenon light source. Acoustic voice analysis and phonetography were established using Dr. Speech (Tiger Electronics Inc.) software. Microlaryngoscopic images were processed by original software created by ELINTA and displayed on a monitor. The relative lengths and widths of vocal fold polyps as well as percentage area of VFP were calculated. The Pearson’s correlation was applied to reveal the correlation between VFP dimensions and acoustic voice parameters. Results. There were no statistically significant differences between the dimensions of left and right vocal folds and VFPs. Statistically significant slight to mild correlations between measured dimensions of VFP acoustic and phonetogram parameters were revealed, with HNR and phonetogram area showing the strongest correlation to the size of VFPs. Conclusion. The results of our study confirm that quantitative microlaryngoscopic measurements of vocal fold polyp and glottal gap dimensions may be a useful tool for objective assessment of glottic incompetence and voice impairment.

AbstractHigh-Speed Videoendoscopy (HSV) is becoming a robust tool for the assessment of vocal fold vibration in laboratory investigation and clinical practice. We describe the first successful application of flexible High Speed Videoendoscopy with innovative laser light source conducted in clinical settings. The acquired image and simultaneously recorded audio data are compared to the results obtained by means of a rigid endoscope. We demonstrated that the HSV recordings with fiber-optic laryngoscope have enabled obtaining consistently bright, color images suitable for parametrization of vocal fold oscillation similarly as in the case of the HSV data obtained from a rigid laryngoscope. The comparison of period and amplitude perturbation parameters calculated on the basis of image and audio data acquired from flexible and rigid HSV recording objectively confirm that flexible High-Speed Videoendoscopy is a more suitable method for examination of natural phonation. The HSV-based measures generated from this kymographic analysis are arguably a superior representation of the vocal fold vibrations than the acoustic analysis because their quantification is independent of the vocal tract influences. This experimental study has several implications for further research in the field of HSV application in clinical assessment of glottal pathologies nature and its effect on vocal folds vibrations.

Bilateral Vocal Fold Immobility

The objectives in treatment of bilateral vocal fold immobility (BVFI) are to achieve adequate airway, preservation of voice quality and laryngeal competence. The present prospective study was designed to evaluate precisely the efficiency and long-term clinical outcome in a series of 13 patients with irreversible BVFI, consecutively managed with endoscopic radiosurgical posterior transverse cordotomy (ERPTC). The operation was performed endoscopically using an Ellman Radiosurgical Instrument and a specially designed electrode. Pre- and post-operative inspiratory function measurements and acoustical vocal analysis were conducted on the patients and were tested for potential statistical relation to successful rehabilitation of the airway. One-step, successful restoration of the airway was achieved in all patients. The post-operative improvement of spirometric values was statistically significant (p < 0.0001), and during the follow-up period of (six to 30) months, airway stability was demonstrated in all patients. In terms of acoustic analysis a non-significant difference was found between pre- and post-operative vocal functions (p > 0.05). This management approach offers an alternative to laser procedures, it provides a ’one-stage’ solution for permanent bilateral vocal fold immobility, and avoids terminal loss of voice quality. The authors’ data confirm the safety, ease of performance, and efficiency of ERPTC in patients with bilateral immobile vocal folds.
