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:
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.

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.
