    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:
    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:
    Aim: The aim of the study was to assess the acoustic and capacity analysis of singing voice using DiagnoScope Specialist software. Material and methods: The study was conducted in 131 adult subjects, including 74 women and 46 men aged 21–51, divided into 3 groups: I – 40 subjects (treatment group) – professional vocalists, II – 40 subjects (treatment group) – semiprofessional vocalists, III – 40 subjects (control group) – students of The Military Medical Faculty at the Medical University of Lodz – nonsingers. The research methodology included: primary medical history, physical examination (otolaryngological), videolaryngoscopic examination, the GRBAS scale for subjective voice evaluation, diagnostic voice acoustic and capacity analysis using DiagnoScope Specialist software, survey on lifestyle patterns which may affect voice quality. R esults: Average value of the fundamental frequency F0 was the highest in professional vocalists group; it was 316.46 Hz in women and 165.09 Hz in men. In semiprofessional vocalists group it was accordingly 260.50 Hz and 149.26 Hz, in nonsingers group it was accordingly 261.23 Hz and 159.27 Hz. The mean value of Jitter parameter in professional vocalists group was 0.30% in women and 0.54% in men, in semiprofessional vocalists group it was accordingly 0.31% and 0.57%, in nonsingers group it was 0.31% and 0.56%. The mean value of Shimmer parameter in professional vocalists group was 3.27% in women and 3.75% in men, in semiprofessional vocalists group it was accordingly 3.46% and 3.77%, in nonsingers group it was 4.33% and 4.39%. The mean value of the NHR index in professional vocalists group was 3.28% in women and 6.00% in men, in semiprofessional vocalists group it was accordingly 3.23% and 6.72%, in nonsingers group it was 3.89% and 6.13%. Conclusions: Values of the parameters which measure the character of the voice, relative period-to-period fundamental frequency perturbations, relative period-to-period amplitude perturbation and level of buzzing together with other methods have diagnostic and predictive value in early detection of voice disorders. Capacity analysis in singing voice showed very low values of the following parameters: phonation time, true phonation time, no phonation coefficient, voice efficiency coefficient and voice capacity.

    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.

    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.
