Background: Dysphonia is altered voice quality, pitch, loudness, or vocal effort that impairs people’s quality of life. It is a very common complaint affecting nearly one-third of a population at some point in their life and could be caused by infection, tumor, trauma, vocal cord paralysis, etc . Indirect mirror or endoscopic laryngoscopy is used to assess the laryngeal condition in dysphonic patients seeking mainly for the cause, but frequently the findings were normal or unremarkable . Videolaryngoscopy (VLS) is very useful in dysphonic patients who have an otherwise normal indirect or flexible laryngoscopic examination. In addition to providing information regarding vocal fold vibrations, the image obtained through VLS can be magnified to make a more detailed assessment of the vocal cord anatomy than is possible with rigid of flexible laryngoscopy. Objective of study: To assess the videolaryngostroboscopic findings in dysphonic patients with normal fiber-optic laryngoscopy. Patient & Method: A cross-sectional study, Fifty patients were included in the study; They had complained of dysphonia, and the fiber-optic laryngoscopic examination was normal. Videostroboscopy were obtained for all patients to assess vocal fold vibration and seek any abnormal findings. Results: A total of 50 patients were enrolled in this study. Regarding the stroboscopic findings, 42% of the patients were normal, 15 (30%) had early soft singer’s nodules, 6 patients (12%) had intracordal lesions, 4 patients (8%)had vocal cord polypoidal changes, 2 patients (4%) had presbylaryngis, and the other 2 patients (4%) had sulcus vocalis. Conclusion: VLS is beneficial in detecting vocal cord lesions in patients with normal fiber-optic laryngoscopy. A high proportion (more than half) of dysphonic patients with normal fiber-optic laryngoscopy had abnormal findings. Keywords: Stroboscopy, Videolaryngoscopy, Fiberoptic laryngoscopy, Dysphonia.

Purpose The factors that influence the evaluation of voice in adulthood, as well as the consequences of such evaluation on social interactions, are not well understood. Here, we examined the effect of listeners' age and the effect of talker age, sex, and smoking status on the auditory-perceptual evaluation of voice, voice-related psychosocial attributions, and perceived speech tempo. We also examined the voice dimensions affecting the propensity to engage in social interactions. Method Twenty-five younger (age 19–37 years) and 25 older (age 51–74 years) healthy adults participated in this cross-sectional study. Their task was to evaluate the voice of 80 talkers. Results Statistical analyses revealed limited effects of the age of the listener on voice evaluation. Specifically, older listeners provided relatively more favorable voice ratings than younger listeners, mainly in terms of roughness. In contrast, the age of the talker had a broader impact on voice evaluation, affecting auditory-perceptual evaluations, psychosocial attributions, and perceived speech tempo. Some of these talker differences were dependent upon the sex of the talker and his or her smoking status. Finally, the results also show that voice-related psychosocial attribution was more strongly associated with the propensity of the listener to engage in social interactions with a person than auditory-perceptual dimensions and perceived speech tempo, especially for the younger adults. Conclusions These results suggest that age has a broad influence on voice evaluation, with a stronger impact for talker age compared with listener age. While voice-related psychosocial attributions may be an important determinant of social interactions, perceived voice quality and speech tempo appear to be less influential.

Laryngoscopic Examination

Posterior glottic laryngeal stenosis most commonly results from endotracheal intubation and less commonly from external trauma or from infection. Following extubation, the patient may have immediate or delayed onset of symptoms of airway obstruction. Often, as in bilateral vocal cord paralysis, voice symptoms are minimal. Indirect laryngoscopic examination usually establishes the diagnosis. Movement of the arytenoids is seen but is limited, and is reflected in poor mobility of the vocal cords. Direct laryngoscopic examination and palpation of the arytenoids for passive mobility confirms the diagnosis and rules out vocal cord paralysis from recurrent laryngeal nerve injury. With the establishment of stenosis, scarring and web formation occurs over the posterior cricoid lamina and may extend into one or both cricoarytenoid joints and into the interarytenoid muscle. Scar contracture in the posterior commissure causes medial fixation of the vocal processes of the arytenoid cartilages. When caused by endotracheal intubation, the initial injury is usually to the mucosa of the posterior cricoid lamina, vocal processes of the arytenoids, or both. Perichondritis may ensue, its location and severity determining the ultimate functional extent of scarring. When airway obstruction results, treatment is by laryngofissure, scar resection, grafting, and stenting. If bilateral cricoarytenoid joint fibrosis is discovered, arytenoidectomy, and in some cases laryngeal lumen augmentation, is invariably required to reestablish the airway, with probable detrimental effects on voice quality. Five of ten patients are presented to illustrate the etiology, pathogenesis, symptoms, management, and sequelae of this problem.

Objectives: The purpose of this study is to investigate the characteristics of vocal fold vibration during sustained vowel /a/ phonation and various semi-occluded vocal tract exercise (SOVTEs) using a vibration simulator and digital kymography (DKG).Methods: A total of 12 normal young speakers (6 males, 6 females) aged 20-30 years participated in the study. They phonated a sustained /a/ vowel and performed SOVTE. The vocal fold vibration characteristics were measured according to the number of vibration sources (single vs. double), and vocal tract occlusion degree using a vibration simulator and DKG. Glottal gap quotient (GQ, %), speed quotient (SQ, %) and amplitude (pixel) were estimated quantitatively from the DKG image.Results: The results showed that significantly higher GQ (p = .000) and SQ (p = .000) were observed in the humming and bilabial fricative /β/ compared to open vowels. The amplitude was significantly higher in the open vowel /a/ than in humming (p = .018) and bilabial fricative /β/ (p = .003). Also, when comparing the vocal fold vibration parameters according to vibration type (single source: straw phonation vs. double source: straw phonation with water), the double source presented a significantly higher GQ (p = .000) as well as SQ (p = .008) in comparison with a single source.Conclusion: SOVTE showed a glottal gap that is different from the opened vowel /a/. It also had a longer opening of the vocal fold and a smaller amplitude than the vowel. This suggests that SOVTE may be helpful for facilitating vocal fold vibration and good voice quality in clinical practice. The current study can be meaningful in providing theoretical and clinical evidence for SOVTE.

Abstract Introduction Inspiratory maneuver corresponds to a simple method used during videolaryngoscopy to increase characterizations of laryngeal findings, through the movement of the vocal fold cover and exposure of the ligament, facilitating its evaluation. Objective To evaluate the increase in diagnosis of benign laryngeal lesions from the usage of inspiratory maneuvers during videolaryngoscopy in patients with or without vocal complaints. Methods A cross-sectional study performed from March 1 to July 1, 2018, in the Laryngology sector of a tertiary hospital. The age of the patients varied from 18 to 60 years old. They were divided into two groups, symptomatic and asymptomatic vocals, and evaluated through videolaryngoscopy together with inspiratory maneuvers. The exams were recorded and later evaluated by three trained laryngologists who determined the laryngeal lesions before and after the inspiratory maneuver. Results There were 60 patients in this sample, 41 of which were vocal symptomatic and 19 asymptomatic. The majority was female and the main complaint was about dysphonia. Before the inspiratory maneuver, the most observed lesions in both groups were chronic laryngitis, followed by vascular dysgenesis. After the inspiratory maneuver, sulcus vocalis was the most frequent additional finding. Conclusion With the inspiratory maneuver, it was possible to increase the identification of structural lesions in the vocal fold, and the most frequent lesion in patients with or without vocal complaints was sulcus vocalis.

Purpose The purpose of this study was to examine the utility of flexible and rigid endoscopy and stroboscopy for the identification of anatomical and physiological features in children with bilateral vocal fold lesions. The secondary purpose was to describe the age distribution of patients who could tolerate use of the different types of endoscopes. Method This cross-sectional clinic-based study included 38 children (ages 5 to 12 years) diagnosed with bilateral vocal fold lesions via videoendoscopy. Vocal fold vibratory characteristics (e.g., mucosal wave) were rated by 4 clinicians by consensus. Results Bilateral vocal fold lesions could be well described anatomically after visualization with both flexible and rigid endoscopes and were most commonly described as symmetrical and broad based. However, the clinicians' confidence in the accuracy of stroboscopy for rating vocal fold vibratory characteristics was limited for both flexible and rigid stroboscopes. Conclusions Videoendoscopy was adequate for viewing and characterizing anatomical structures of bilateral vocal fold lesions in pediatric patients; however, vibratory characteristics were often not fully visualized with videostroboscopy. In view of the importance of visualizing vocal fold vibration in the differential diagnosis and treatment of vocal fold lesions, other imaging modalities, such as high-speed videoendoscopy, may provide more accurate descriptions of vocal fold vibratory characteristics in this population.

Efficacy Of Treatment

ABSTRACT Bowing of the vocal folds can result from aging, atrophy or idiopathic causes, such as an injudicious vocal cord surgery. Bowing results in dysphonia due to inadequate approximation of the vocal folds. A number of treatments have been proposed for this condition. Intracordal injection of biological materials including liquid silicon and Teflon and various types of thyroplasty have been utilized. However, full voice recovery has never been fully achieved. We present a case involving a 64-year-old Asian man with dysphonia for 30 years. The patient's vocal fold bowing was examined on laryngoscopy. The disease was effectively treated with pulsed dye laser (PDL) followed by speech therapy. Observation of the patient over 1 year did not show any signs of recurrence. Our analysis revealed voice quality improvement. How to cite this article Koo YC, Chung HJ, Suh MJ, Choi HS. The Efficacy of Treatment for Vocal Fold Bowing with Pulsed Dye Laser.

Abstract Background Obesity is considered a health problem that affects many systems of the body among which the respiration and voice. The objective of the study was to analyze the impact of obesity in children on quality of their voice. Thirty obese children were included in this cross-sectional study and compared to 30 age- and sex-matched healthy children as a control group. Voice of cases and controls were assessed subjectively by auditory perceptual assessment and objectively by studying acoustic parameters using Computerized Speech Lab. Flexible laryngoscopy was done for cases with dysphonia. Results Dysphonia perceived in 60% of cases, voice analysis revealed increased jitter and noise to harmonic ratio with significant difference than controls. Conclusion The voice of children with morbid obesity reveals significant modifications pertaining to vocal characteristics in comparison to non-obese persons, so voice hygiene and voice therapy could be added to their therapy program as prophylactic or therapeutic management of voice disorder.
