Streszczenie:

Vocal folds are an essential part of human voice production. The biomechanical properties are a good indicator for pathological changes. In particular, as an oscillation system, changes in the biomechanical properties have an impact on the vibration behavior. Subsequently, those changes could lead to voice-related disturbances. However, no existing examination combines biomechanical properties and spatial imaging. Therefore, we propose an image registration-based approach, using ultrasound in order to gain this information synchronously. We used a quasi-static load to compress the tissue and m

Objective Consuming less water (systemic dehydration) has long been thought to dehydrate the vocal folds. An in vivo , repeated measures study tested the assumption that systemic dehydration causes vocal fold dehydration. Proton density (PD)–weighted magnetic resonance imaging (MRI) of rat vocal folds was employed to investigate (a) whether varying magnitudes of systemic dehydration would dehydrate the vocal folds and (b) whether systemic rehydration would rehydrate the vocal folds. Method Male ( n = 25) and female ( n = 14) Sprague Dawley rats were imaged with 7T MRI, and normalized PD-weight

The use of high-speed video-endoscopy (HSV) in the study of phonatory processes linked to speech needs the precise identification of vocal fold boundaries at the time of vibration. The HSV is a unique laryngeal imaging technology that captures intracycle vocal fold vibrations at a higher frame rate without the need for auditory inputs. The HSV is also effective in identifying the vibrational characteristics of the vocal folds with an increased temporal resolution during retained phonation and flowing speech.

The specula are useful in the following ways: 1) clarifying blind spots for improved diagnosis and providing more accurate surgical margins; 2) observing the lower lips of the vocal folds in phonosurgery; and 3) Vaporizing with laser reflection.

Treatment is initially directed at reversing medical conditions and patterns of abuse with surgery reserved for unresolving lesions resulting in troublesome dysphonia. Benign lesions that require surgery are excised as precisely as possible sparing overlying mucosa and the underlying vocal ligament.

Vocal pitch is used as an important communicative device by humans, as found in the melodic dimension of both speech and song. Vocal pitch is determined by the degree of tension in the vocal folds of the larynx, which itself is influenced by complex and nonlinear interactions among the laryngeal muscles. The relationship between these muscles and vocal pitch has been described by a mathematical model in the form of a set of ‘control rules’. We searched for the biological implementation of these control rules in the larynx motor cortex of the human brain. We scanned choral singers with function

AbstractThe use of tissue autofluorescence for the detection and localization of cancer of the larynx is described. In this pilot study, eight patients with probable carcinoma of the vocal folds underwent laryngoscopy in which the tissue autofluorescence spectra of normal and pathologically confirmed tumour tissue were acquiredin vivo. Fluorescence images of the suspect areas were also acquired using the LIFE system (Xillix Technologies Corp.). The results suggest that the autofluorescence properties of laryngeal tissue, under 442 nm illumination, are similar to those of bronchial tissue and t

AbstractWith easier access to more sophisticated imaging techniques, the investigation of vocal fold palsy is reassessed. A questionnaire was sent to all ENT surgeons in the UK to establish which imaging techniques are available to ENT departments and which tests are currently requested during the investigation of vocal fold palsy.An extensive literature review established the aetiology of vocal fold palsy and the sensitivity and specificity of radiological investigations.A simple protocol is proposed which would be suitable to implement in the majority of ENT departments in the UK.

About 11,600 cases of laryngeal cancer were reported in the United States in 1995, accounting for 1% of all reported cancers. Fewer than 1% of laryngeal cancers are sarcomas, osteosarcoma being the rarest type. Twelve cases of laryngeal osteosarcoma have been cited in the literature. A 47-year-old man presented with hoarseness following a benign vocal polypectomy. The entire larynx appeared swollen, although both vocal folds moved well. Biopsies did not reveal pathologic tissue. Computed tomographic imaging revealed a destructive, expansile lesion of the thyroid cartilage. A computed tomograph

Standard endoscopy of vocal folds is in general limited to two-dimensional imaging. Laser-based 3D imaging offers not only absolute measurements but also the possibility of assessing all three spatial directions. However, due to human inter-individuality, a fixed grid configuration (with fixed edge length and spot size) does not necessarily provide the best coverage and resolution. We present a liquid lens optical design for a diffractive spot array generator with dynamic adjustment capabilities for both array size and spot size. The tunable nature of the liquid lenses enables precise control

Introduction. Laryngeal disorders are characterized by a change in the vibratory pattern of the vocal folds. This disorder may have an organic origin described by anatomical fold modification, or a functional origin caused by vocal abuse or misuse. The most common diagnostic methods are performed by invasive imaging features that cause patient discomfort. In addition, mild voice deviations do not stop the individual from using their voices, which makes it difficult to identify the problem and increases the possibility of complications. Aim. For those reasons, the goal of the present paper was

Objectives Signal typing is central to the understanding of vocal fold vibratory patterns. Digital kymography (DKG) allows the direct observation of vocal fold vibratory patterns, and therefore, using DKG for vibratory signal typing may provide a useful complement to traditional signal typing techniques. Methods Video data collected from 20 larynges excised from mongrel dogs were observed with DKG in order to find examples of type 1 (nearly periodic), type 2 (subharmonic), and type 3 (aperiodic) vibratory patterns. The time series, frequency spectra, and correlation dimensions were calculated

Immobility, fixation, or paralysis of the vocal folds is an ominous sign when encountered in the clinics. This may be due to a variety of diseases, lesions, injuries, or vascular compromise which may affect the integrity and physiologic mechanism of the vocal folds. The common etiologies include infectious processes such as laryngeal or pulmonary tuberculosis (PTB), malignancy or neoplasms, central problems such as cerebrovascular accidents (CVA), stroke and others.1,2,3 The problem should be addressed immediately because this potentially life threatening and imminent narrowing of the glottic

ABSTRACT Aims and objectives Vocal cord palsy (VCP) can be definitely depicted on computed tomograpy (CT) scan by identifying key points at the level of true vocal cords and aryepiglottic folds. There are various VCP mimics and imaging shortcomings, and these can usually be circumvented by thoughtfully assessing the scan plan and level, and a diligent search for additional characteristics. Materials and methods This retrospective study consisted of 10 cases of unilateral VCP, who all had been clinically diagnosed of VCP and further evaluated by CT.

The human voice originates from oscillations of the vocal folds in the larynx. The duration of the voice onset (VO), called the voice onset time (VOT), is currently under investigation as a clinical indicator for correct laryngeal functionality. Different analytical approaches for computing the VOT based on endoscopic imaging were compared to determine the most reliable method to quantify automatically the transient vocal fold oscillations during VO. Transnasal endoscopic imaging in combination with a high-speed camera (8000 fps) was applied to visualize the phonation onset process. Two differ
