Presbylarynx refers to age-related structural changes of the vocal folds that include muscle atrophy, reduced neuromuscular control, loss of superficial lamina propria layer, and reduced pliability. The changes result in thin and bowed vocal folds, increased vocal effort requirements, breathy voice, change in habitual pitch, and strain. The primary treatment options are voice therapy focused on strengthening breath support and the intrinsic muscles of the larynx, and optimization of resonance; injection augmentation of the vocal folds; and type I thyroplasty. Functional dysphonia is defined as change in voice quality in the absence of structural or neurological abnormalities of the larynx. Muscle tension dysphonia (MTD) is a subtype of functional voice disorders and involves laryngeal muscle tension imbalance due to excessive or dysregulated activation resulting often in strained or breathy voice. MTD can be divided into primary (psychological etiology or vocal misuse) and secondary (compensatory for organic laryngeal pathology). The mainstay of treatment for MTD is voice therapy, along with medical or surgical treatment of the underlying vocal pathology in secondary MTD. Mutational falsetto, or puberphonia, is a functional voice disorder where a high-pitched, pre-adolescent voice fails to transition to the lower pitch of adulthood.

Purpose Previous studies have reported that voice therapy via telepractice is useful for patients with nodules and muscle tension dysphonia. Nevertheless, telepractice for elderly patients with voice disorders has not yet been investigated. We conducted this study to examine the hypothesis that voice therapy via telepractice is not inferior to conventional voice therapy. Method Eighty patients with dysphonia aged more than 55 years participated in this study from September 2016 to June 2018. After screening the inclusion and the exclusion criteria, 69 patients were randomized into telepractice (33 patients) and conventional (36 patients) groups. The outcome measurements included Voice Handicap Index-10, videolaryngostroboscopy, maximum phonation time, auditory-perceptual evaluation, and acoustic analysis. Paired t test, Wilcoxon signed-ranks test, and repeated measures analysis of variance were used to examine treatment outcomes. Results The diagnoses of voice disorders included atrophy ( n = 33), unilateral vocal paralysis ( n = 13), muscle tension dysphonia ( n = 7), nodules ( n = 6), and polyps ( n = 10). No significant differences were observed in age, sex, and baseline measurements between the two groups. Twenty-five patients in the telepractice group and 24 patients in the control group completed at least four weekly sessions. Significant improvements were observed for all the outcome measures ( p < .05) in both groups. Improvements in Voice Handicap Index-10 in the telepractice group (24.84 ± 5.49 to 16.80 ± 8.94) were comparable to those in the conventional group (22.17 ± 7.29 to 13.46 ± 9.95, p = .764). Other parameters also showed comparable improvements between the two groups without statistically significant differences. Conclusions This is the first randomized controlled trial comparing telepractice and conventional voice therapy in elderly patients with voice disorders. The results showed that the effectiveness of voice therapy via telepractice was not inferior to that of conventional voice therapy, indicating that telepractice can be used as an alternative to provide voice care for elderly patients with vocal disorders.

The mucus layer on the vocal folds was examined by videostrobolaryngoscopy in patients with laryngeal tension-fatigue syndrome, a chronic functional dysphonia due to vocal abuse and misuse. Besides the findings in previous reports (such as abnormal glottal closure, phase or amplitude asymmetry, and the irregular mucosal wave), the vocal folds during vibration had an uneven mucus surface. The occurrence of an uneven mucus layer on vocal folds was significantly greater in subjects with this voice disorder (83% or 250 of 301 patients in this series) than in those without voice disorders (18.5% or 5 of 27). The increase of mucus viscosity, mucus aggregation, and the formation of rough surfaces on the vocal folds alter the mechanical properties that contribute to vibration of the cover of the vocal folds, and thereby worsen the symptoms of dysphonia in patients with laryngeal tension-fatigue syndrome.

Muscle tension dysphonia (MTD) is a voice disorder characterized by excessive tension of the laryngeal muscles during phonation. Voice therapy is the gold standard of treatment for MTD. However, patients with MTD do not always respond to voice therapy. Multidisciplinary approaches have been attempted to treat intractable MTD such as lidocaine instillation, lidocaine injection to recurrent laryngeal nerve, botox injection and excision of false ventricle using CO2 laser. Recently, injection laryngoplasty is suggested that assists in more efficient phonation and voice therapy to MTD patients. A patient with intractable MTD underwent lidocaine injection and injection laryngoplasty showed improved voice quality and remained stable until postoperative 3 months without any complications.

Objective To compare presenting symptoms, etiology, and treatment outcomes among dysphonic adults <65 and ≥65 years of age. Study Design Retrospective cohort study. Setting Tertiary care voice center between January 2011 and June 2016. Methods A total of 755 patients presenting for dysphonia were included in the study: 513 adults <65 years of age and 242 adults ≥65. Data collected included demographics, referral information, prior diagnoses, prior treatments, clinical examination findings, diagnosis, coexisting symptoms, treatments, and pre- and postintervention Voice Handicap Index scores. Statistical analysis was performed with SPSS to determine significant relationships between variables of interest. Results The most common etiologies of dysphonia were vocal cord atrophy (44.8%) in the ≥65 cohort and benign vocal cord lesions (17.8%) in the <65 cohort. When compared with adults <65 years old, patients ≥65 had a higher incidence of neurologic dysphonia ( P = .006) and vocal cord atrophy ( P < .001) but were less likely to have laryngopharyngeal reflux ( P = .001), benign vocal cord lesions ( P < .001), or muscle tension dysphonia ( P < .001). Overall, 139 patients had surgery, 251 received medical therapy, and 156 underwent voice therapy. The ≥65 cohort demonstrated improvement in Voice Handicap Index scores after surgery ( P = .001) and voice therapy ( P = .034), as did the <65 cohort (surgery, P < .001; voice therapy, P = .015). Adult surgical patients <65 reported greater improvements than patients ≥65 ( P = .021). Conclusions There are notable differences in the pathophysiology of dysphonia between patients aged ≥65 and <65 years. Although adults <65 reported slightly better outcomes with surgery, patients ≥65 obtained significant benefit from surgery and voice therapy.

Objectives This study investigated the effectiveness of a specialized manual physical therapy (PT) program at improving voice among patients diagnosed with concomitant muscle tension dysphonia (MTD) and cervicalgia at a tertiary care voice center. Materials and Methods Cervicalgia was determined by palpation of the anterior neck. Both voice therapy (VT) and PT was recommended for all patients diagnosed with MTD and cervicalgia. PT included full-body manual physical therapy with myofascial release. Patients underwent: 1) VT alone, 2) concurrent PT and VT (PT with VT), 3) PT alone, 4) VT, but did not have PT ordered by treating clinician (VT without PT order) or 5) VT followed by PT (VT then PT). The pairwise difference in post–Voice Handicap Index-10 (VHI-10) controlling for baseline variables was calculated with a linear regression model. Results 178 patients met criteria. All groups showed improvement with treatment. The covariate-adjusted differences in mean post–VHI-10 improvement comparing the VT alone group as a reference were as follows: PT with VT 9.95 (95% confidence interval 7.70, 12.20); PT alone 8.31 (6.16, 10.45); VT without PT order 8.51 (5.55, 11.47); VT then PT 5.47 (2.51, 8.42). Conclusion Among patients diagnosed with MTD with cervicalgia, treatment with a specialized PT program was associated with improvement in VHI-10 scores regardless of whether they had VT. While VT is the standard of care for MTD, PT may also offer benefit for MTD patients with cervicalgia.
