    Opis:
    Objective: The process of ageing begins after 60 years of age and is referred to as presbyphonia (Vox senium). The causes include functional or organic voice disorders, often coexisting with dry upper respiratory tract infection. Introduction: The aim of the study is the use of high-speed camera and acoustic voice analysis in diagnostics of the clinical form of presbyphonia. M aterials and methods: The study included a group of 50 men, non-smokers, age from 51 to 72, who do not use their voice professionally. High-Speed Digital Imaging and HS camera have been used, allowing evaluation of real vibrations of vocal folds, along with acoustic voice analysis using a software by DiagNova Technologies. Results: VHI questionnaire has been used for self-assessment of voice disability. Visualizations of the larynx enabled recognition of hypofunctional dysphonia or atrophy of vocal folds that cause voice disorders. This was confirmed by parameters of voice acoustic evaluation: F0, NHR, narrowband spectrography. The pathological value of NHR and the presence of nonharmonic components in the range of high frequency levels indicated glottal insufficiency, recorded with the visualization technique of the larynx by HS camera. A significant shortening of maximum phonation time in relation to the control group has also been recorded. Discussion: The objective examination of voice pathology is crucial in diagnosis and rehabilitation, however, subjective assessment of the patient is important in the scope of the procedure used. The patient’s subjective self-rating assessment (VHI) confirmed the sense of voice disorders in elderly men, indicating the need for rapid and accurate clinical diagnosis.

    Opis:
    Introduction: 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. The aim of the study was to diagnose the clinical form of Presbyphonia in elderly women using High Speed Digital Imaging (HSDI) and acoustic voice analysis. Material and methods: Study included 50 elderly women (average age 69) with dysphonia (Group I). Control group (Group II) included 30 women (average age 71) without voice quality disorders. Visualization assessment has been conducted with High Speed Digital Imaging (HSDI) with High Speed camera (HS). Acoustic evaluation of voice included analysis isolated vowel “a” and continuous linguistic text with Diagnoscope Specialista software. Maximum Phonation Time (MPT) has been determined. Results: In Group I, 78% of women revealed vocal folds vibrations asymmetry, vibration amplitude increase, Mucousal Wave (MW) limitation and Type D glottal insufficiency (GTs). Acoustic voice analysis proved decrease in F0, increase in Jitter, Shimmer, NHR. In 22% of women, next to vibrations asymmetry, vibration amplitude reduction and MW limitation, Type E glottal insufficiency (GTs) have been found. Acoustic voice analysis revealed slight decrease in F0 and the presence of numerous non-harmonic components in the glottis region. Conclusions: Vocal folds visualization with HSDI showed edema, less often atrophy in elderly women. Both forms of dysphonia were caused abnormal values of F0, Jitter, Shimmer, NHR in the acoustic voice evaluation and significant reduction of MPT.

    Opis:
    Ectopic pancreas is a rare congenital disorder defined as pancreatic tissue lacking vascular or anatomic communication with the normal body of the pancreas. Most cases of ectopic pancreas are asymptomatic, but it may become clinically evident depending on the size, location and the pathological changes similar to those observed in case of the normal pancreas. It is often an incidental finding and can be located at different sites in the gastrointestinal tract. The most common locations are: the stomach, duodenum or the proximal part of small intestine. The risk of malignancy, bleeding and occlusion are the most serious complications. Despite the development in diagnostics, it still remains a challenge for the clinician to differentiate it from neoplasm. In this report, we described a case of 28-years old woman who presented recurrent epigastric pain. The upper gastrointestinal endoscopy revealed gastrointestinal stromal tumor on the border of the body and antrum of the back wall of great curvature of the stomach. The histopathological examination after surgery showed heterotopic pancreatic tissue. Ectopic pancreas should be considered in the differential diagnosis of gastric mass lesions.

    Opis:
    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. The aim: The aim of the study was to classify phonatory compensation mechanisms after CO2 laser cordectomy using the HSDI. M aterial and methods: The study included 30 men treated and diagnosed at the Department of Otolaryngology and Department of Clinical Phonoaudiology and Logopedics, Medical University of Bialystok. The control included 30 men with no pathological changes in the larynx. Type III, IV and Va CO2 laser cordectomy have been for glottis cancer treatment. Postoperative evaluation has been conducted 6 months after the surgery. HSDI has been used in larynx visualization. R esults: Type I compensation occurs most frequently in patients after type III cordectomy. Advanced glottis cancer, as an indication for type IV and V cordectomy, leads to epiglottic hyperfunction and phonation involving vestibular folds – type II and III compensation. Type IV compensation is most frequent in type IV cordectomy. C onclusions: The type compensation is connected with the extent of glottis resection. In cordectomy including anterior commissure and the part of opposite fold (type Va), supraglottic hyperfunction with the participation of vestibular folds (type II and III compensation) has been recorded. Transmuscular cordectomy (type III) most often resulted in type I compensation. Type III-Va cordectomy caused reduction or absence of MW, decrease in amplitude and aperiodicity of vibrations in HSDI.

    Opis:
    Introduction: 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. The aim: 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. Material and method: The study included 30 men after CO2 cordectomy. 13 (43%) patients underwent type III cordectomy, 6 (20%) – type IV; 11 (37%) – type Va. Voice quality has been assessed 6 months after the surgery. Control group included 30 healthy men of the same age. GRBAS scale has been used in perceptual evaluation of voice. Acoustic analysis has been performed using DiagnoScope Specjalista software. Narrowband spectrography and Maximum Phonation Time (MPT) measure has been performed. Results: In study group, voice has been classified as G1R1B0A0S0 after type III cordectomy; as G1R1B1A1S2 in type IV and as G2R1B1A0S3 in type Va. Acoustic evaluation revealed the highest values of F0, Jitter, Shimmer and NHR after Va cordectomy as well as non-harmonic components in narrowband spectrography and reduction of MPT. Conclusions: Postoperative voice quality depends on the type of cordectomy. Perceptual assessment indicates that type IV and Va cordectomy cause intensification of voice disorders. Parameters of acoustic evaluation increase with the extent of the procedure. The presence of non-harmonic components in narrowband spectrography increases with the extent of cordectomy, such as the reduction of MPT. Preservation of anterior commissure influences good voice quality in perceptual and acoustic assessment.

    Opis:
    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. The study included 50 patients with psychogenic dysphonia diagnosed in the Department of Clinical Fonoaudiology and Logopedics, Medical University of Białystok and treated at the Foniatric Outpatient Clinic, University Hospital in Białystok in 2017–2018. The control group consisted of 30 subjects with euphonic voice. All patients underwent subjective and objective assessment of voice and speech quality. The GRBAS scale, breathing pathway assessment, respiratory-phonatory-articulation analysis, voice and speech intensity evaluation have been performed. Speech prosody has also been examined. Patient selfassessment of voice has been conducted using Voice Handicap Index (VHI). Objective evaluation of larynx included vibrations of vocal folds visualization using High Speed Digital Imaging (HSDI). Acoustic analysis of voice quality has been performed using DiagNova Technologies. The maximum phonation time (MPT) has been determined. Hyperfunctional dysphonia is the most common clinical form of psychogenic dysphonia. Abnormal breathing pathway influence the reduction of MPT and disturbance of respiratory-phonatory-articulation coordination in patients with psychogenic dysphonia. In psychogenic dysphonia intonation and speech rate disorders are observed. Results of voice self-assessment in the majority of examined patients indicates a mild voice disability.

    voice disorders in pregnancy
    Opis:
    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. Subjective assessment has been based on the GRBAS scale. Objective assessment of the vocal organ used the HSDI technique (High Speed Digital Imaging). In the laryngeal visualization, high-speed camera (HS) using rigid endoscope with 90 ° optics has been used. Vibration of vocal folds has been recorded during phonation of vowel "e" at 4000 frames / sec. The glottal closure (GTs), symmetry, regularity and synchronization of vocal folds vibration have been assessed. In estimating the degree of glottal insufficiency, kymography of the larynx has been performed by analyzing the value of Open Quotient (OQ). Objective acoustic evaluation of voice has been also conducted using DiagnoScope Specjalista Program. Hoarseness has been observed in 15 pregnant women, whereas voice fatigability in 20 patients. Using HSDI, the edema of vocal folds in part of the group has been observed. Decreased MPT has been found in all examined women in the third trimester of pregnancy. Hoarseness and fatigability of voice are the most frequent subjective symptoms of voice organ in the third trimester of pregnancy. Decreased MPT is recorded objectively, as well as edema and insufficiency of vocal folds using HSDI technique.

    Opis:
    Abstract 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. The aim of the study is perceptive evaluation of vestibular voice, objective larynx visualization, acoustic and aerodynamic examination. The study included 40 patients: 20 with vestibular voice, 20 with euphonic voice. Voice quality has been evaluated using perceptual GRBAS scale. Endoscopic and stroboscopic larynx examination used Endo-STROB-EL-Xion GmbH with visual tract. High-Speed Digital Imaging (HSDI) and High Speed (HS) camera registered true vocal folds vibrations. Acoustic evaluation of voice with DiagnoScope Specjalista, DiagNova Technologies included analysis of F0, Jitter, Shimmer, NHR, nonharmonic components. MPT has been analyzed. In examined group, hoarseness (95%), roughness (75%) and voice strain (55%) have been recorded. Endoscopy revealed edema of vestibular folds with dilation of vessels covering glottis. Stroboscopy and HSDI confirmed coexistence of hyperfunctional (95%) or paralytic (5%) dysphonia. Acoustic assessment revealed increase in Jitter, Shimmer, NHR and decrease in F0 and MPT. The vestibular voice is observed most frequently in women with hyperfunctional dysphonia (phononeuroses) or in paralytic dysphonia. Visualization techniques confirm the coexistence of vestibular folds hypertrophy and edema with vibration disorders. In the perceptual assessment, vestibular voice was hoarse, rough and strained. Acoustic examination showed increase of Jitter, Shimmer, NHR, presence of nonharmonic components and decrease of F0 and MPT.
