Multidimentional assessment of voice quality in patients with laryngopharyngeal reflux disease.

<b><br>Introduction:</b> Gastroesophageal Reflux Disease (GERD) is a common disorder in world population. As a result of the regurgitation of acid content from the stomach to laryngopharynx and larynx, secondary damage of laryngeal mucosa occur, which is highly sensitive to hydrochloric acid, and morphological changes are observed. Symptomatology of laryngopharyngeal reflux is varied which makes differential diagnosis difficult.

Specifics and diagnostic procedure in reflux-related dysphonia.

Voice is a work tool for many professional groups. Currently, cases of dysphonia of multiple origin consist a growing issue. Voice disorders may result from disturbed voice production process, congenital defects, post-traumatic conditions, chronic diseases or hormonal disorders.

Application of High Speed Digital Imaging (HSDI) technique and voice acoustic analysis in the diagnosis of the clinical form of Presbyphonia in women.

<b>Introduction:</b> The aging process of voice begins after the age of 60 and has an individually variable course. Voice quality disorders at this age are called senile voice (Presbyphonia or Vox Senium). Voice pathology is particularly severe in women.

Perceptual and acoustic voice analysis in patients with glottis cancer after endoscopic laser cordectomy.

<b>Introduction:</b> Treatment of glottis cancer, despite oncological safety, should consider postoperative voice quality. CO₂ laser endoscopic cordectomy allows radical removal of the tumor while maintaining respiratory, defensive and phonatory functions. <br><b>The aim:</b> The aim of the study is perceptual and acoustic evaluation of voice in patients after endoscopic CO2 III-Va laser cordectomy due to glottis cancer.

Phonatory compensation in patients with larynx cancer after CO2 laser cordectomy.

Introduction: CO2 laser endoscopic cordectomy is the method of laryngeal cancer treatment. The type of cordectomy (I-VI) depends on the extent of the tumor. Endoscopic laser surgery provides more satisfactory phonation conditions in comparison to open surgical procedures.

Verbal communication disorders in psychogenic dysphonia.

Psychogenic dysphonia is defined as disturbances in voice and speech quality with emotional background with lack of organic changes in the larynx. Mental condition has significant impact on the process of producing voice, functioning of respiratoryphonatory- articulation mechanism and speech prosody. The aim of the study was visual, acoustic, perceptual assessment as well as self-assessment of voice and speech quality using subjective and objective methods in patients with psychogenic dysphonia.

Analysis of voice quality parameters in patients with vestibular voice.

Vestibular voice includes participation of larynx structures which are absent in physiological process. Vestibular phonation may be desired when vocal folds are damaged as in paralytic dysphonia, or undesired in marginal hyperfunction. Vestibular voice may result from psychogenic dysphonia - phononeurosis.

Subjective and objective assessment of voice quality in pregnancy.

During pregnancy, voice quality disorders may occur in form of: edema, dryness, nervousness. The aim of the study is subjective and objective evaluation of voice quality in pregnant women. The study included 20 women in the third trimester of pregnancy, age of 20-31 diagnosed at the Department of Clinical Phonoaudiology and Logopedics, Medical University of Bialystok.

Psychogenic voice disorders.

Introduction: Voice express the psyche and personality of a person. Psychogenic dysphonia is called Phononeurosis. Neurosis, depression or family, occupational and social conflicts are the cause of voice disturbances.

Usefulness of high-speed digital imaging (HSDI) in the diagnosis of oedematous - hypertrophic changes of the larynx in people using voice occupationally.

Introduction: The aim of the study is the evaluation of the usefulness of High-Speed Digital Imaging (HSDI) in the diagnosis of organic dysphonia in a form of oedematous-hypertrophic changes of vocal fold mucosa, morphologically confirmed by Transmission Electron Microscopy (TEM) method in patients working with voice occupationally.

Material And Methods: The group consisted of 30 patients working with voice occupationally with oedematous-hypertrophic changes of vocal fold mucosa. Parameters of vocal folds vibrations were evaluated using HSDI technique with a digital HS camera, HRES Endocam Richard Wolf GmbH.

[High-speed digital imaging in the clinical analysis of voice change as a parameter of premenstrual syndrome].

Unlabelled: Technique of high-speed digital imaging (HSDI) is unique technology, allowing assessment of real vocal fold vibrations.

Aim: The aim of the study is to present the usefulness of HSDI in the diagnosis of premenstrual dysphonia as a parameter of premenstrual syndrome (PMS).

Materials And Methods: In study conducted by Department of Clinical Phonoaudiology and Logopedics at the Medical University of Białystok participated 21 women aged between 20-31 years old.

[Application of Brain-Boy Universal Professional in preliminary assessment of auditory processing disorder].

Unlabelled: Increasing numbers of hearing pathology is auditory processing disorders. Auditory Processing Disorders (APD) are defined as difficulty in using auditory information to communicate and learn in the presence of normal peripheral hearing. It may be recognized as a problem with understanding of speech in noise and perception disorder of distorted speech.

[Effects of electrostimulation therapy in selected cases of vocal fold paralysis].

Unlabelled: Paralytic dysphonia is the most serious neurogenic pathology of voice quality. An important issue is to identify methods which support routine treatment.

Aim: The aim of the study is to assess voice quality after electrostimulation (ES) therapy in patients with paralytic dysphonia.

[Rehabilitation of phonosurgically treated patients with edematous-hypertrophic changes of larynx].

Unlabelled: Advanced change of organic dysphonia are an indication for phonosurgery. Edematous-hypertrophic changes are cause of serious disturbances of voice. High-speed digital imaging (HSDI) technique is the unique method, allowing for assessment the effects of therapy and rehabilitation.

An analysis of occupational dysphonia diagnosed in the North-East of Poland.

Objective: The objective of the study was to evaluate factors predisposing to occupational dysphonia in a group of professional voice users.

Material And Methods: The study involved 374 patients treated in the Clinic of Otolaryngology and the Phoniatric Outpatient Clinic, Department of Otolaryngology, Medical University of Białystok in 1999--2001. Group I consisted of 309 patients qualified as professional voice users.
