Anxiety and depression in patients with vocal fold nodules, edema and polyps.

PURPOSE: To compare the prevalence and severity of depression and anxiety among patients with vocal fold (VF) nodules, polyps and edema. At the same time the aim was to analyse association between severity of distress and the level of vocal handicap as well as to identify other factors related to severity of depression and anxiety in these patients. METHODS: To all participants were given five questionnaires: (1) questionnaire on socio-demographic and some other characteristics of patient; (2) Beck's Depression Inventory (BDI); (3) State-Trait Anxiety Inventory (STAI) 1 (State Anxiety); (4) STAI 2 (Trait Anxiety); and (5) Voice Handicap Index (VHI)-10. RESULTS: A total of 205 patients were included in this study. Mild-to-severe depression, according to BDI was present in 79 (38.6%) patients. Mild-to-severe state anxiety and trait anxiety were present in 199 (97.1%) and 200 (97.6%) patients, respectively. Only 10 patients had VHI-10 score ≤ 11. Multivariate analyses showed that there were no significant differences in the level of depression and anxiety between patients with VF nodules, polyps and edema. The VHI-10 score was significantly higher in patients with VF edema in comparison with VF nodule patients (p = 0.001), as well as in comparison with VF polyp patients (p = 0.001). CONCLUSION: The present study identified a high prevalence of psychological and vocal distress among patients with vocal disorders. Severity of depression and anxiety did not differ between patients with VF nodules, polyps and edema, and it was not related to the level of vocal handicap.

Transcultural Adaptation and Validation of the Voice Handicap Index-10 into the Serbian Language.

BACKGROUND: The Voice Handicap Index-10 (VHI-10) is used in clinics because of its validity and ease of use by patients. OBJECTIVES: The aim of this paper was to evaluate the internal consistency, reliability, and clinical validity of the Serbian version of the VHI-10. METHOD: In this cross-sectional study, we translated the original English version of the VHI-10 into Serbian, after which it was back-translated into English. The Serbian version of the VHI-10 was completed by 161 patients with voice disorders, divided into 4 groups according disease etiology (structural, neurological, functional, and inflammatory) and 73 healthy control subjects. RESULTS: The VHI-10 internal consistency was 0.88. Spearman's rank correlation coefficient for VHI-10 test-retest reliability was ρ = 0.991 (p< 0.001). Patients with voice disorders had higher median total VHI-10 scores compared with controls (p< 0.001). The patients' Grade, Instability, Roughness, Breathiness, Asthenia, and Strain (GIRBAS) scale scores were significantly correlated with the VHI-10 test scores (ρ = 0,682, p < 0.001) and VHI-10 retest scores (ρ = 0.716, p < 0.001). CONCLUSION: The Serbian version of the VHI-10 had good validity and reliability and can be used by Serbian patients with voice disorders.

Laser transoral microsurgery in treatment of early laryngeal carcinoma.

PURPOSE: Laser transoral laryngeal microsurgery has become widely accepted treatment method because of its organ and function preservation and shorter period of hospitalization. The aim of this study was to examine the overall, disease-specific and disease-free survival in patients with early laryngeal carcinoma treated with laser depending on age, gender, common risk factors (tobacco and alcohol use), histopathological tumor grade, anterior commissure involvement, performed tracheotomy, positive surgical margins, T stage, type of endoscopic cordectomy, postoperative radiotherapy and laryngeal preservation. METHODS: Retrospective study included 234 patients with squamocellular carcinoma of the larynx treated with laser transoral laryngeal microsurgery. 5-year overall, disease-specific and disease-free survival and the prognostic impact of mentioned factors were evaluated using Kaplan-Meier and Cox proportional hazard analyses. RESULTS: 5-year OS and DSS was 92.5% and 95.3%, respectively. OS was significantly lower for older patients and in patients with histologically poorly differentiated tumors, 3 and 5 years postoperatively (Log rank test; p = 0.031). DSS was significantly lower in patients with anterior commissure involvement, positive surgical margins and patients who underwent postoperative RT. DFS was significantly lower in patients with anterior commissure involvement, patients with T1b tumor stage and patients who underwent cordectomies type Vb and VI (Log rank, p < 0.05). Laryngeal preservation significantly influenced 5-year OS, DSS and DFS (Log rank, p ≤ 0.001). Multivariate Cox regression analysis showed that age, histological tumor grade and laryngeal preservation were significant negative prognostic factors for 5-year DSS and DFS. CONCLUSION: Transoral laryngeal microsurgery delivers excellent oncological results, even in selected patients with higher stages of early laryngeal cancer and anterior commissure involvement.

European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Head and Neck Module, updated version: Preliminary psychometric data from Serbian laryngectomized patients.

BACKGROUND: We provided preliminary psychometric data for the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Head and Neck Module, updated version (QLQ-H&N43) from a group of Serbian laryngectomized patients. METHODS: The study included 170 subjects. The QLQ-H&N43 is a 43-item questionnaire, with 12 multi-item scales and 7 single-item symptom scales. All subjects also completed the Quality of Life Questionnaire-Core 30-questions (QLQ-C30). RESULTS: Good internal consistency (Cronbach's α of above 0.7) was found for 5 of the 7 scales. All QLQ-H&N43 scales correlated negatively as predicted with all QLQ-C30 functioning scales. The correlations with the QLQ-C30 symptoms supported discriminant validity, with only one exception: the head and neck social eating scale overlapped with the QLQ-C30 pain scale. For 14 of 19 QLQ-H&N43 scale scores, significant known-group differences were observed between those who differ in type of laryngectomy, adjuvant therapy, or 5-year survival. CONCLUSION: Preliminary evidence suggests that a great majority of the QLQ-H&N43 scales have acceptable internal consistency and promising construct validity, but more research studies are needed with other cancer groups to extend these findings. © 2015 Wiley Periodicals, Inc.

Laryngeal Granuloma - Benefit in Treatment with Zinc Supplementation?

Laryngeal granulomas present as contact and postintubation ulcers and granulomas. Essentially, a contact granuloma is a pseudotumor of the lateral wall of the posterior glottis. The most common etiological factor is voice abuse, with predisponing factors such as reflux disease. Postintubation ulcers and granulomas, although of different etiology, according to all the other traits belong to this clinical entity. The therapy of choice is conservative treatment. Surgical laser excision is indicated for resistant cases and those whose size is causing respiratory distress. Treatment of laryngeal granulomas with zinc supplementation is reported in the literature as one of the forms of conservative treatment, and we wanted to consider it in this review. Zinc is an essential mineral that plays a vital role in many biochemical reactions and is considered very important for wound healing.

Stroboscopy in detection of laryngeal dysplasia effectiveness and limitations.

Vocal fold pathology changes the appearance and vibratory patterns observed during stroboscopic examination, but a strict correlation between the vibratory pattern and the dysplasia type does not exist. The aims of this study were to determine the role of stroboscopy in vocal fold dysplasia assessment and to determine whether stroboscopy is the deciding factor when performing laryngomicroscopy with biopsy in suspicious lesions. This prospective controlled study involved 112 patients with laryngeal dysplasia treated over a 2-year period at a tertiary medical center. Patient data and clinical, stroboscopy, laryngomicroscopy, and histopathologic reports were reviewed. During the stroboscopy, glottic occlusion, phase symmetry, periodicity, amplitude, mucosal wave, and nonvibratory segments were followed. Laryngomicroscopy with different types of endoscopic cordectomies (types I-III) was performed as a therapeutic measure, with a 12-month follow-up period. Nonvibrating segments were present in 15.1% of the patients with mild dysplasia and in 38.5% of the patients with moderate dysplasia. In 45.5% of the patients with severe dysplasia (carcinoma in situ), nonvibrating segments were absent. The amplitude of vocal fold vibrations in patients with mild dysplasia (P=0.03) was a significant factor indicative of recurrent disease, but none of the stroboscopic signs was significant for the disease progression. Severe dysplasia can be related to both nonvibrating and vibrating vocal fold segments. Stroboscopy cannot be used reliably for classifying laryngeal dysplasia and may indicate the need to perform laryngomicroscopy with biopsy in suspicious vocal fold lesions. The warning factors for recurrence and progression of dysplasia are treatment modality, abnormal amplitude of vibration, and nonvibrating segment.

[Botulinum toxin efficacy in the treatment of patients with spasmodic dysphonia].

BACKGROUND/AIM: Spasmodic dysphonia (DS) is a disabling speech disturbance appearing as the consequence of dystonic vocal folds contraction. Its intermittent appearance in the laryngeal muscles causes vocal function discontinuation. The quality of life of these patients is significantly disturbed. Surgical and a medical therapy appear to be inadequate and unsuccessful ones of no steady improvement. It is the botulinum toxin therapy that proved to be highly efficacious one, with the established improvement in 80-100% of patients. The aim of our study was to evaluate the efficacy of botulinum toxin therapy in patients with SD and to show our preliminary results. METHODS: The study included 10 patients with adductor spasmodic dysphonia. After diagnostic procedures, botulinum toxin was applied either in one or both vocal folds, in doses of 12-16 units each. In our study we applied indirect technique originally developed by Hocevar and Pirtosek. Perceptive voice and speech analysis was performed prior to and after the instillation of botuline toxin as per structured Scale of pathological characteristics of voice and speech appearing in the spasmodic dysphonia. RESULTS: The majority of our patients experienced both subjective improvement and the improvement in the terms of the quality of life, Voice Henolicap Index--(VHI) that was rated as rather significant one (t = 3.562; p = 0.006). CONCLUSION: Regardless unquestionable improvement of definite phonation, further function restitution requires individual vocal therapy and psychotherapy. Vocal therapy includes structural vocal techniques which reduce degree of vocal tension and rapid changes in the power and the height of voice. Further investigations are necessary for the scope of the definition of a standardized therapeutically procedure for spasmodic dysphonia treatment which comprises multidisciplinary approach in diagnosis, therapy and treatment efficacy evaluation.
