[Spontaneous cervical emphysema and pneumomediastinum with voice disorders].

Spontaneous cervical emphysema and pneumomediastinum, occurring in the absence of previous disorders or provocating factors, is very rare. The predominant symptoms are retroesternal pain, dyspnea, dysphagia and neck pain. The diagnosis is established radiologically. The evolution is generally good and conservative therapy leads to recovery in most patients. We present an unusual case of pneumomediastinum, cervical and retropharyngeal emphysema that spread to cavum; the suspected symptom was voice alteration as reported by the parents.

[Time aspects of short-latency acoustic evoked potentials in cleaners-up after the Chernobyl AES accident who have voice disorders].

Brain stem SLAEP were compared to EEG readings in patients with vocal problems consequent to low-dose radiation received after the Chernobyl accident. Versus control subjects, the patients had significantly (p < 0.01) longer latent periods of SLAEP waves 11 and V as well as the interpeak interval I-V. EEG findings indicated in patients changes in the diencephalic and diencephalic-stem regions, CNS dysfunction in the form of cortical structure irritation in the presence of low cerebral bioelectric activity. As shown by objective methods, the above patients with vocal problems have CNS disorders. This should be taken into consideration in planning treatment and incapacity decisions for such subjects.

Effects of the manual laryngeal musculoskeletal tension reduction technique as a treatment for functional voice disorders: perceptual and acoustic measures.

During a 2-year period, 17 patients with "functional dysphonia" were assessed and managed in a hospital setting. A single treatment approach, known as manual laryngeal musculoskeletal tension reduction, was employed. The effects of the therapy regimen were analyzed using perceptual and acoustical measures of vocal function. The results indicated a significant change in the direction of "normal" vocal function in the majority of patients within one treatment session. Perceptual measures of severity were consistently more likely to be rated as normal following treatment. Acoustic measures of voice confirmed significant improvements in jitter, shimmer, and signal-to-noise ratio (SNR). Results are discussed in terms of the clinical utility and effectiveness of this treatment approach for functional dysphonia.

Acoustic recognition of voice disorders: a comparative study of running speech versus sustained vowels.

The signals of running speech and sustained vowels of normals and subjects suffering from dysphonia were analyzed statistically with respect to the signal-to-noise ratio (SNR). The distribution of the SNR measured in multiple overlapping frames in the speech signal was described by a linear combination of the distribution frequencies for SNR = 0 dB, 0 dB less than SNR less than 15 dB, and SNR greater than or equal to 15 dB. The values of the linear combination, the SNR of the vowels, and clinical assignment of the voices to normal and pathologic populations based on laryngoscopic and stroboscopic investigation parameters were used to compare the different evaluations of the voices. The SNR distribution in speech remained stable over signal lengths of more than 30 s. The correlation coefficient between the SNR measure for running speech and the SNR of sustained vowels amounted to only 0.63. The error rate in the discrimination between normal and dysphonic voices amounted to 22.6% in application to sustained vowels and 5.6% when the SNR distribution was used. Possible reasons for the observed discrepancies are discussed, and the results are compared to those of other studies.

Hypnotherapeutic intervention for voice disorders related to recurring juvenile laryngeal papillomatosis.

Recurring juvenile laryngeal papillomatosis is resistant to cure, and thus usually requires multiple operations which may lead to the extensive proliferation of vocal fold scar tissue. Severe hoarseness, sharply lower pitch, and weak loudness levels are common sequelae. Adjunctive hypnotherapy can increase motivation for change, speed up the acquisition of vocal skills, and possibly even facilitate or sustain remission of growths in selected patients. An 8-year-old girl with severe active eruptions went into remission after 16 sessions, and a 12-year-old boy, already in remission at the beginning of the intervention period, remained free of neoplasms throughout the regimen. Whether or not hypnosis contributed significantly to the sanguine results, it is probable that, at the least, the hypnotic intervention facilitated the achievement of certain technical objectives in voice therapy.

[Present day diagnosis of voice disorders in children].

Videoendostroboscopy (VESS) was employed for diagnosis of vocal dysfunction in 369 children aged 6 to 16 years. Effects of flexible and hard endoscopes were compared. Vibratory cycle was analyzed in 55 healthy children of different age. Diagnosis and differential diagnosis of soft and hard nodules, physiological and long-term mutation, chronic laryngitis are described as well as a videoendostroboscopic picture in functional dysphonias, vocal grooves and polyps. VESS is a modern, informative and safe diagnostic procedure.

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.

[Video-laryngo-stroboscopy in diagnosis of senile voice disorders].

Clinical applications of videolaryngostroboscopy (VLSS) in 110 senile persons in phoniatrics was investigated. Each patient was examined laryngologically and phoniatrically. The patients were divided into two groups, according to the changes observed in the larynx as edema and vocal folds atrophy. Measurements of vibration, amplitudae, frequency glottic closure and oscillation (mucosal wave) of vocal cords yielded objective information about vibration in edema and vocal fold atrophy. This method can find application in training and therapeutic procedures in patients with senile dysphonia.

[Voice disorders in benign nodose formations of the vocal cords in vocalists. Their treatment and rehabilitation].

The paper presents data on 5-year follow-up of 105 patients with neoplasms of the vocal cords. All the examinees belonged to vocal profession (actors, singers, musical students). Among the new growths of the vocal cords true or false vocal nodules occurred most frequently (84%). The second in frequency were fibromas and polyps (15%). Contact granuloma occurred only in 2 males with long smoking history. The diagnosis and treatment efficacy assessment were performed using measurement of maximal phonation time, electron laryngostroboscopy, electron glottography.

[Voice disorders, dyspnea, aspiration. A laryngeal injury can be the cause].

Injuries to the larynx may have extracorporeal (external), or endolaryngeal (internal), causes and are here classified on the basis of traumatic mechanisms. External trauma may be due to the action of blunt force or sharp objects--also including ruptures. Internal injuries may occur as a result of endotracheal intubation (also for anesthesia), long-term intubation and mechanical ventilation, ingestion of foreign bodies, surgical or nonsurgical interventions. In some cases, laryngeal injuries may be difficult to diagnose and evaluate. If the patient survives the primary traumatic event and his vital functions are preserved and stable, a careful laryngoscopic exploration--where indicated also such imaging procedure as high-resolution CT, direct microlaryngoscopy and laryngometry--should be applied to establish the diagnosis and decide on appropriate treatment.
