Voice and vocal self-assessment after thyroidectomy

Voice alterations after thyroidectomy can be found even with preserved function of laryngeal nerves. The purpose of this study was to evaluate voice before and after thyroid surgery and the role of orotracheal intubation on voice changes.

Noise-to-Harmonics Ratio as an Acoustic Measure of Voice Disorders in Boys ☆

This prospective study assessed the efficacy of computerized noise-to-harmonics ratio (NHR) to quantify perceptual and endoscopic findings of dysphonia and/or structural lesion of the vocal fold. Fifty Brazilian boys without vocal complaints were submitted to computerized, perceptual, and endoscopic examination. Thirty boys were dysphonic--3 were classified into the grade category, 5 into breathiness, 9 into roughness, and 15 into grade/breathiness. Vocal fold lesions were observed in 25 boys (17 nodules and 8 cysts). The Mann-Whitney U test revealed that NHR was significantly higher in boys with a structural lesion (p = 0.007) and in boys with dysphonia (p < 0.0001). However, according to a logistic regression model, only the occurrence of dysphonia was explained by NHR; the risk for having dysphonia increased approximately twice (odds ratio = 1.92, 95% confidence interval = 1.3-2.9) with each increase of 0.01 in NHR. Our results suggest that noise is a useful quantitative index to confirm a perceptual diagnosis of dysphonia and to evaluate quantitative changes in a dysphonic voice over time. However, we believe that computerized analysis should be used as a complement, rather than a substitute, for perceptual evaluation. Further studies with a larger sample are required to investigate the relationship between noise and lesions of the vocal folds.

Quality of Life Related to Swallowing After Tongue Cancer Treatment

The surgical treatment of tongue cancer, with or without reconstruction and/or radiotherapy, leads to different levels of voice, speech, and deglutition disorders. Evaluating the quality of life related to these swallowing alterations is important to further our knowledge about the impact of such alterations from the patient’s point of view. Our objective was to describe the quality of life related to swallowing in patients treated for tongue cancer, using specific questionnaires. Twenty-nine patients participated in the study for a minimum of one year after oncologic treatment. Patients with advanced disease who underwent radiotherapy had significantly worse scores in most domains. The aspects related to how to deal with deglutition problems, time taken for meal consumption, pleasure in eating, chewing problems, food sticking in throat and mouth, choking, and the knowledge of feeding restrictions, which were evaluated by different domains of SWAL-QOL, were factors that contributed to a negative impact for patients with advanced-stage tumors who underwent radiotherapy.

Prevalence of Upper Aerodigestive Symptoms in Patients Who Underwent Thyroidectomy With and Without the Use of Intraoperative Laryngeal Nerve Monitoring

BACKGROUND Upper aerodigestive symptoms (UADS) have been reported by patients who have had thyroidectomies. This study evaluated the long-term prevalence of UADS after thyroidectomy in patients who did and who did not have intraoperative neuromonitoring (IONM). METHODS This was a cross-sectional study of patients with normal vocal fold mobility who had a thyroidectomy. It included patients who did and did not have this surgery with IONM. All patients answered a questionnaire regarding UADS occurring one or more years after thyroidectomy. The questionnaire dealt with UADS relating to voice and swallowing symptoms and sought to quantify their severity. The 208 patients who underwent thyroidectomy without IONM were designated the control group (CG). The 100 patients who underwent thyroidectomy with IONM were designated the neuromonitored group (NMG). RESULTS The proportion of patients in the CG who reported UADS was 45%; 25.9% of these patients reported voice symptoms, and 33.6% reported swallowing symptoms. The proportion of patients in the NMG who reported UADS was 39%; 27% of these patients reported voice symptoms, and 22% reported swallowing symptoms. Thus, patients in the CG had more swallowing symptoms and a greater severity of UADS-related symptoms than patients in the NMG. CONCLUSIONS In this study, IONM had a favorable effect in terms of decreasing the prevalence and severity of UADS occurring one year or more after thyroidectomy.

Vocal Handicap and Quality of Life After Treatment of Advanced Squamous Carcinoma of the Larynx and/or Hypopharynx

OBJECTIVE/HYPOTHESIS To evaluate and correlate voice-specific quality of life (QOL) and health-related QOL (HR-QOL) after treatment for advanced cancer of the larynx and/or hypopharynx. STUDY DESIGN Cross-sectional study. METHODS Patients submitted to partial laryngectomy (PL), salvage PL (sPL), concomitant radiotherapy and chemotherapy (RT+Chemo), total laryngectomy (TL), salvage TL (sTL), total pharyngolaryngectomy (TP) and salvage total pharyngolaryngectomy (sTP). The following questionnaires were used: (1) Voice Handicap Index (VHI) and (2) University of Washington Quality of Life Questionnaire (UW-QOL; version 4). RESULTS Eighty-four patients participated in the study. All the patients PL (10), sPL (1), and RT+Chemo (24) communicated by laryngeal voice. Of the 49 patients submitted to total removal of the larynx, 30 communicated with alaryngeal phonation, the major part being tracheoesophageal prosthesis (17). The worst subscale of VHI for the total patient group was functional (mean=13.15), and the value of the total score was 31. Patients submitted to PL, RT+Chemo, and TL presented slight handicap (medians of 27, 14, and 21.5, respectively). Patients treated with sTL, TP, and sTP presented moderate handicap (medians of 45, 37.5, and 31.5, respectively). HR-QOL was considered between good and excellent for 78.6% of the patients, and poor for 21.4%. The correlation between voice-specific QOL and HR-QOL was significant (P=0.0001). CONCLUSION Patients treated for advanced cancer of the larynx/hypopharynx present slight to moderate voice handicap and good/excellent HR-QOL. Stricter analysis of both the VHI and UW-QOL data suggests that more attention be given to the vocal handicap of the individual patient.

Associação entre os achados do questionário de disfagia M. D. Anderson e a videofluoroscopia da deglutição após tratamento do câncer de cabeça e pescoço.

Introduction The use of symptom-specific questionnaires on head and neck cancer (HNC), together with objective swallowing measures, can be sensitive to changes in quality of life (QoL) resulting from dysphagia, but this tool is not broadly used as a complement to clinical evaluations. Purpose To analyze the correlation between the M. D. Anderson Dysphagia Inventory (MDADI) questionnaire and videofluoroscopy (VF) in patients treated for head and neck cancer. Methods This is a retrospective study with review of clinical data, VF and MDADI results. The study sample was composed of adult patients (>18 y.o.) treated for tumors at the oral cavity, oropharynx, hypopharynx, and larynx, regardless of treatment type. For the VF examination, swallowing of 5 and 20 ml of nectar-thick liquids were considered. The Mann-Whitney nonparametric test was applied to evaluate the correlations between the MDADI and VF. Results Thirty-nine patients, mostly men (87.18%), with mean age of 61 years participated in the study. Most patients (16) presented oral cavity tumors (41.03%). Twenty-two patients were in advanced clinical stage (IV). Surgery was the most prevalent treatment (41.03%). Approximately half of the participants (20) received oral feeding. The total mean (TM) on the MDADI was 63.36. Comparison between VF and MDADI data showed significant correlation between TM, emotional domain (ED), and physical domain (PD) with penetration during the swallowing of 5 ml. Penetration and aspiration with 20 ml determined worse QoL on the global (p=0.018 and p=0.0053), emotional (p=0.0012 and p=0.027) and physical (p=0.0002 and p=0.0051) domains, and TM (p=0.0023 and p=0.0299), respectively. The presence of stasis did not determine worse QoL. Conclusion Patients treated for HNC who presented penetration/aspiration showed worse QoL on the emotional and physical domains of the MDADI.Introduction The use of symptom-specific questionnaires on head and neck cancer (HNC), together with objective swallowing measures, can be sensitive to changes in quality of life (QoL) resulting from dysphagia, but this tool is not broadly used as a complement to clinical evaluations.

Multidimensional effects of voice therapy in patients affected by unilateral vocal fold paralysis due to cancer

INTRODUCTION Patients with unilateral vocal fold paralysis may demonstrate different degrees of voice perturbation depending on the position of the paralyzed vocal fold. Understanding the effectiveness of voice therapy in this population may be an important coefficient to define the therapeutic approach. OBJECTIVE To evaluate the voice therapy effectiveness in the short, medium and long-term in patients with unilateral vocal fold paralysis and determine the risk factors for voice rehabilitation failure. METHODS Prospective study with 61 patients affected by unilateral vocal fold paralysis enrolled. Each subject had voice therapy with an experienced speech pathologist twice a week. A multidimensional assessment protocol was used pre-treatment and in three different times after voice treatment initiation: short-term (1-3 months), medium-term (4-6 months) and long-term (12 months); it included videoendoscopy, maximum phonation time, GRBASI scale, acoustic voice analysis and the portuguese version of the voice handicap index. RESULTS Multiple comparisons for GRBASI scale and VHI revealed statistically significant differences, except between medium and long term (p<0.005). The data suggest that there is vocal improvement over time with stabilization results after 6 months (medium term). From the 28 patients with permanent unilateral vocal fold paralysis, 18 (69.2%) reached complete glottal closure following vocal therapy (p=0.001). The logistic regression method indicated that the Jitter entered the final model as a risk factor for partial improvement. For every unit of increased Jitter, there was an increase of 0.1% (1.001) of the chance for partial improvement, which means an increase on no full improvement chance during rehabilitation. CONCLUSION Vocal rehabilitation improves perceptual and acoustic voice parameters and voice handicap index, besides favor glottal closure in patients with unilateral vocal fold paralysis. The results were also permanent during the period of 1 year. The Jitter value, when elevated, is a risk factor for the voice therapy success.

Vocal quality evaluation in children without voice disorders: a prospective and double-blind study

Abstract In this study, 50 males from 3 to 10 years of age were examined with the aim of detecting voice disorders. Twenty-five of them were normal, eight had vocal cysts, and 17 presented with vocal nodules without any underlying laryngeal pathology. Perceptual auditory analyses and measures of phonatory function were performed by a trained speech therapist. Normal vocal quality was significantly more frequent in the normal group; roughness and breathiness were associated with the pathological groups (p
