    [Show abstract] [Hide abstract] ABSTRACT: Cochlear Implant (CI) is the most advanced method of treatment in receptive type of deafness and profound hearing loss. Good functioning auditory organ plays a significant role not only in auditory perception but also in the process of phonation, giving the possibility of good realization of the process of verbal communication. The aim of the study is to assess the quality of voice and life in adults with pre- and postlingual deafness treated using cochlear implant. Twenty six patients with pre- (group I) and postlingual (group II) deafness deriving no benefit from hearing aids were included into the study. Voice quality was assessed using subjective and objective methods. The endoscopic (VLS) and stroboscopic (VLSS) examination of the larynx and the acoustic voice analysis were carried out. The quality of life was assessed using the Nijmegen Cochlear Implant Questionnaire (NCIQ). Examinations were conducted before implantation and 6 months after activation of speech processor. In the subjective and objective assessment of voice quality the improvement was registered in both groups. The effects were less spectacular in prelingual patients. In this group of patients the subjective assessment of voice quality and stroboscopic examination confirmed the hypofunctional type of dysphonia. In postlingual patients the hyperfunctional type of dysphonia was registered what was confirmed by the analysis of acoustic parameters of voice. The improvement of quality of life was observed in both groups of patients after implantation. The voice quality was improved after implantation in both analyzed groups. In patients with postlingual deafness values of parameters of voice quality assessment were closed to physiological. Results of the subjective assessment of voice quality were confirmed by objective examinations and the acoustic voice analysis. Rehabilitation with cochlear implant gave the opportunity for active participation in private and social life, improving the quality of life in patients with pre- and postlingual deafness.

    [Show abstract] [Hide abstract] ABSTRACT: Unlabelled: Cochlear Implant (CI) is the most advanced technical solution in the treatment of profound hearing loss and deafness in patients of all age groups. The aim of the study was to analyse the speech and linguistic disorders in adults with pre- and postlingual deafness rehabilitated with Cochlear implant (CI). Material and methods: 21 adults with pre- (I group) and postlingual (II group) deafness deriving no benefit from hearing aids participated in this study. Phonatory organ was examined by endoscopy (VLS) and stroboscopy (VLSS). Test of Auditory Perception (TSS) was conducted directly after the activation of speech processor and after rehabilitation. The logopedic assessment before and after CI was based on the examination of motoric activity of articulatory organs, type of respiration, loudness of speech and the assessment of articulation. The linguistic assessment of grammatical and lexical aspect was carried out. The prosodic elements of speech were also analysed. Results: Stroboscopic examination pointed to hypofunction of larynx in patients with prelingual deafness and hyperfunction--in postlingual deafness. The values of TSS were improved after CI, especially in patients with postlingual deafness. The most severe disorders of the efficiency of articulatory organs were observed in patients with prelingual deafness before CI. In the group of prelingually deaf patients disorders of the articulation of vowels and consonants as well as the lexical and grammatical aspect of speech were improved after CI. The correctness of syntax and inflection, development of active vocabulary, improvement of prosodic elements of speech were noticed in patients with postlingual deafness after CI. CONCLUSIONS. Patients with postlingual deafness achieved better results of rehabilitation in auditory perception than prelingually deaf patients. The linguistic improvement of grammatical and lexical aspect was noticed especially in prelingually deaf patients after implantation. This group of patients achieved also the significant progress in prosodic elements of speech in comparison with the results before implantation.

    [Show abstract] [Hide abstract] ABSTRACT: Disorders of voice quality are mostly influenced by organic changes in larynx. In the assessment of ultrastructure of vocal fold mucosa the most useful is the technique of transmission electron microscopy (TEM). The organic dysphonia is diagnosed by the perceptual, endoscopic (VLS) and stroboscopic (VLSS) assessment of larynx and acoustic assessment. The aim of the study was to determine morphological changes and voice quality disorders in patients with edema of larynx. 40 patients with vocal folds edema (I group) and 10 patients with no pathological changes of larynx (II group) were included in the study. The morphological assessment of vocal folds mucosa was carried out with the usage of transmission electron microscopy (TEM). The voice quality was examined by the subjective and objective methods. The endoscopic and stroboscopic (VLS and VLSS) examination of larynx and acoustic analysis of voice were carried out. Morphological changes of vocal folds mucosa were observed. Epithelial cells showed features of vacuolar degeneration. Moreover enlargement of intercellular spaces, small rugosity of basal membrane and inflammatory infiltration of stroma, a large number of blood vessels and a cumulation of elastic and collagenous fibers were observed. Stillness of vocal folds influenced disorders of voice quality with features of dysphonia. The endoscopic and stroboscopic examination of larynx clinically shows the morphological changes of vocal folds mucosa. Simple and non-invasive acoustic examination of voice in patients with edema of larynx objectively confirms the subjectively registered dysphonia.

  • [Show abstract] [Hide abstract] ABSTRACT: The aim of the rehabilitation in laryngectomized patients is to produce phonatory communication. It is important to choose the optimal method of rehabilitation. Most of the patients use the oesophageal or pharyngeal speech as an effect of natural rehabilitation with vocalistic method. Another group of larygectomized patients is rehabilitated with surgical method which leads to shunt speech. THE AIM OF STUDY was to compare the quality of oesophageal and shunt speech with euphonic voice to choose the optimal method of rehabilitation in laryngectomized patients. The quality of vicarious phonation was examined in 30 patients with shunt speech and in 20 patients with oesophageal speech. Examination results of the subjective, objective and acoustic assessment were compared with values registered in physiological (euphonic) speech. The results of objective assessment were statistically analysed. The shunt and oesophageal speech enabled effective verbal communication of laryngectomized patients. The parameters of clinical subjective and objective assessment of shunt speech pointed to its high quality which is similar to physiological phonation. The acoustic analysis of voice confirmed the results of subjective and objective assessment of quality of shunt voice and speech in laryngectomized patients. In conclusion, the surgical rehabilitation of voice after total laryngectomy gave patients the great opportunity for a remarkable improvement in vicarious phonation.

  • [Show abstract] [Hide abstract] ABSTRACT: Vocal fold polyp is usually a result of the injury of the vocal cords. It often appears after vocal overuse or misuse causing trauma in vocal fold mid-membranous and wound formation. THE AIM OF THE STUDY was to assess the activity of hexosaminidase in vocal fold polyps in the comparison to the control tissue. Vocal polyps (n=8) were collected from 8 patients during direct laryngoscopy. Specimens of normal vocal folds were obtained from 8 cadavers (n=8) served as controls. Specimens were immediately frozen in -80 degrees C. To assess hexosaminidase activity, release of p-nitrophenol from p-nitrophenol derivatives was used. We observed statistical differences between the activity of investigated enzyme in all vocal folds specimens compared with that in normal tissue homogenates. However the activity of HEX achieved a low level. Mean release of HEX from the activated cells in vocal fold specimens was 1.073 nkat/g wet tissue compared with 0.766 nkat/g wet tissue in normal cadaveric vocal fold homogenates. Low activity of HEX in vocal fold polyps suggests that inflammation may not be a primary factor in the development of the disease and other mechanism should likely be considered in the pathogenesis of vocal fold polyps.

    [Show abstract] [Hide abstract] ABSTRACT: Voice disorders constitute a serious health problem for teachers. More than 80% of them experience voice disorders and still among those 40% suffer from pathological phoniatric changes confirmed by phoniatric examination. Chronic disorders resulting from vocal abuse and misuse are the most frequent among occupational diseases diagnosed in Poland. To investigate the chronic voice disorders among the teaching community of Medical University of Bialystok and to examine its awareness of voice hygiene and proper vocal techniques. The research was based on a survey of 434 university teachers from Medical University of Bialystok. Results. Increased voice fatigue and voice loss were most often the consequence of prolonged voice use (over 20 years). Occupational voice disorders were more frequent in females, even though they did not ignore initial symptoms and consulted specialists. Disregard for prevention, reluctance to undergo treatment, and negligence of the first symptoms of disease are the most common cause of occupational voice disorders. Working in a voice-friendly environment, organizing trainings devoted to voice hygiene and vocal techniques are in favor of enhancing the voice function of university teachers.

    [Show abstract] [Hide abstract] ABSTRACT: Voice rehabilitation with the application of voice prostheses is a method of choice in surgical rehabilitation of patients following total laryngectomy. To compare voice quality and fistula speech with use of second generation voice prostheses to voice and esophageal speech in patients rehabilitated with vocal method. The following study comprised 37 patients with fistula speech (group I). The assessment of voice quality included subjective and objective examination and acoustic analysis of fistula speech and aesophageal. Examination results were compared with data obtained in 15 patients with oesophageal voice of similar age and gender composition (group II). The acoustic analysis was performed using IRIS Medicom software. Fo values and Jitter, Shimmer, HNR parameters were analysed. All examined patients with fistula speech demonstrated a permanent capacity of speaking, which enabled efficient verbal communication. Average values obtained during 'perception test' located this type of phonation between good and very good speech. Formant recordings in narrow-band spectrographs indicated relatively normal supraglottal articulation which is a factor conditioning good speech comprehension. During subjective assessment, fistula voice and speech were moderately loud, dull, hoarse, uttered in unrestrained, breathed way rather than being forced. Persistence of the pathologic phonation was confirmed by acoustic voice evaluation parameters (Jitter, Shimmer, HNR and Fo). Examination findings confirm better voice quality obtained in rehabilitation with second generation voice prostheses as compared to oesophageal voice and speech resulting from natural rehabilitation process.

    [Show abstract] [Hide abstract] ABSTRACT: The evaluation of voice quality of 22 patients with obstructive sleep apnea syndrome (OSAS), who underwent uvulopalatopharyngoplasty (UPPP), was performed. The voice quality was assessed before the operation, and 1 month and 6-months after the procedure. The grade of dysphonia was determined on a six-grade dysphonia scale according to the Union of European Phoniatricians. Maximum phonation time (MPT) was analyzed. The acoustic examination of voice was performed determining fundamental frequency (F0) value and shimmer, jitter and NHR acoustic parameters. Formants analysis of voice was made estimating the level of F1, F2, F3 and F4 formants. Registered hearing dysphonia directly after the surgery was transient. The surgery did not significantly change F0 and jitter parameters that decrease the grade intensification of dysphonia. The reduction of maximum phonation time, changes in jitter and NHR acoustic parameters as well as the reduction of F3 and F4 formants confirmed the occurrence of open nasality directly after UPPP. Registered voice quality and timbre disturbance after UPPP were periodic.

    [Show abstract] [Hide abstract] ABSTRACT: Vocal cord paralysis, a complication after strumectomy, affects about 1% of treated patients. Patients with unilateral paralysis are usually treated with foniatric and conservative therapy. Bilateral vocal cord paralysis with the paramedial placement of vocal folds usually requires surgical treatment. Trachoetomy is often done because of dyspnoe. The surgical procedures widening of glottis are performed in case no improvement after conservative therapy. In 1989 Denis and Kashima first described the method of CO2 laser posterior cordectomy This method seems to be an effective and reliable surgical procedure. 36 patients with bilateral vocal cord paralysis underwent CO2 laser posterior cordectomy The follow-up period ranged from 6 to 36 months. All patients were decannulated by the third day after surgery. The subjective evaluation of patients concerning treatment was satisfied. The operation resulted in significant improvement in the field of respiratory function of the larynx and a slight objective aggrevation in the quality of voice.

  • [Show abstract] [Hide abstract] ABSTRACT: Connexins are integral transmembrane proteins which form specialized hemichannels (connexons) in the plasma membrane. These structures make up gap junctions in adjacent cells which allow for rapid propagation of action potential and slow diffusion of nonorganic ions, secondary messengers, and other small water-soluble molecules (<1.0-2.0 kDa). Connexin proteins are crucial for the formation of gap junctions. Twenty human and 21 murine connexin isoforms (23-64 kDa) have been described so far. Traditional nomenclature in the CxMW format takes into account only the molecular weight of a given connexin. A more recent classification is based on structural gene similarities, their homology and sequence, as well as the length of connexins' cytoplasmic domains. Connexins, as all proteins, have a unique amino-acid sequences and molecular weights and exhibit specific biochemical properties. However, all of them have a common 3-D structure with four hydrophobic transmembrane domains (TM1-TM4), one cytoplasmic (CL) and two extracellular (E1-2) loops, and C- and N-terminal cytoplasmic regions. The cytoplasmic loop and C-terminal regions bind other structural proteins, creating a protein complex crucial for synchronized intercellular communication.

    [Show abstract] [Hide abstract] ABSTRACT: Exposure of nasal mucosa to various allergic and/or non-allergic stimuli might result in rhinitis. Allergic rhinitis affects 10-25% of population making it the most prevalent allergic disorder. Seasonal and perennial allergic rhinitis affect up to 30% and 10% of pediatric population, respectively. Prevalence of allergic rhinitis varies between studies: in Poland, Breborowicz et al. reported allergic rhinitis in 16.7% of children aged 6-7, whereas Emeryk et al. observed perennial allergic rhinitis in 3.6% and seasonal allergic rhinitis in 6.2% of 8-15 year olds. Allergic rhinitis similarly to other diseases results in direct, indirect and hidden costs. In the USA (2002) direct costs were estimated at $4.195 billions and indirect at $665 millions (total of $4.863 billions). Allergic rhinitis co-exists with multiple respiratory conditions, significantly increasing treatment costs incurred by patients' and places additional burden on public finances. It also has a detrimental effect on patients' and their families' quality of life. Allergic rhinitis--although non-life threatening--significantly worsens quality of daily life and as such should be perceived as a serious medical condition not only by patients but also by medical professionals who are in position to diagnose it and implement appropriate therapeutic interventions.

  • [Show abstract] [Hide abstract] ABSTRACT: The objective of the study was to examine influence of inhaled glycocorticosteroids on phoniatric function of the larynx in patients suffering from asthma. Thirty minutes after the administration and long-term therapy effect of the inhaled glycocorticosteroids on local condition of the phoniatric organ was assessed in 15 patients with recently diagnosed bronchial asthma. The diagnostics of asthma included: subjective and objective examination, prick tests, spirometry, total IgE and histamine test for bronchial hyperactivity. Evaluation of voice function was implemented subjectively and objectively with use of videolaryngostroboscopy (VLSS). Acoustic assessment of voice was also performed. Administration of glycocorticosteroids as inhaled discs resulted in incidents of cough, mouth and throat dryness, sensation of polydipsia and skin inflammation around the mouth. Occasionally, hoarseness and discomfort in the larynx area were noted. On long-term administration, dysphonia, hoarseness and voice fatigue due to dysfunction of innermost larynx muscles, particularly vocal fold adductors. After 30 minutes of the glycocorticosteroid administration in patients with recently diagnosed asthma, irritation of the pharynx and larynx mucosa was recorded. The long-term treatment with inhaled glycocorticosteroids resulted in myopathy of proper muscles of the larynx.

    [Show abstract] [Hide abstract] ABSTRACT: Atrophic changes of vocal folds may cause serious disturbances of voice quality called dysphonias. The group of 50 patients with advanced neoplasmatic disease, anorexia and elderly patients were researched. In order to assess voice quality, usual subjective diagnostic methods were used and also modern techniques of imagine of the larynx. Phonation function was examined by means of factors aerodynamic laryngeal function. The data were then analysed statistically. We found usefulness of primary, subjective examination of laryngeal phonation function in the diagnosis of vocal folds atrophy. The videolaryngostroboscopy (VLSS) allowed to distinguish clearly the organic dysphonia with the vocal folds atrophy. The evaluation of factors such as MFR, PQ, VVI showed coexistence of hypofunctional component in (phonation) in patients with the vocal folds atrophy which is important in therapy of this kind of dysphonia.

  • [Show abstract] [Hide abstract] ABSTRACT: In recent years FESS has become a gold standard in the treatment of chronic sinusitis. The results of the treatment depends to a high degree on the thorough preoperative assessment and qualification for surgery, as well as applied criteria reported for success. The aim of the study was to evaluate the early results of FESS in patient with chronic sinusitis after 3 to 12 month of follow up focusing attention on some prognostic factors. In the group 52 patients who underwent FESS in 2003 due to chronic sinusitis particular attention to standardization of pre and postoperative evaluation was paid. Meticulous analysis of the data from SNAQ 11 (sino nasal assessment questionnaire) questionnaire for subjective complaints evaluation, and assessment of the extent of disease according to Friedman, Kennedy and Levine scale revealed no correlation between extent of disease and results of treatment. It was demonstrated, that there is the statistically significant correlation between extent of sinus disease on CT scans and the duration of disease. It applies to the first tree years of disease.

    [Show abstract] [Hide abstract] ABSTRACT: Analysis of professional dysphonia in 309 patients treated in Phoniatric Outpatient Clinic of the (chair and) Department of Otolaryngology AM in Bialystok was performed. The teachers of primary and lower secondary schools were the majority of the patients. The teachers were compared with the 65 patients of other occupations. Additional harmful factors were excluded in both groups. In all patients' otolaryngologic, phoniatric and videostroboscopic examinations were completed. The analysis paid attention to functional and organic dysphonias. In the group of voice workers there were found early functional laryngeal disorders, which were progressive with the period of work. In other patients organic disorders were more common and occurred earlier than functional ones. The degree of dysphonia depended on laryngeal pathology, especially in case of functional dysphonia.

    [Show abstract] [Hide abstract] ABSTRACT: The objective of the study was to evaluate factors predisposing to occupational dysphonia in a group of professional voice users. 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. The obtained results were compared with those yielded in a group of 65 persons of other occupations (group II). All the diagnosed patients neither smoked nor abused alcohol. Tobacco smokers, patients with chronic diseases of the respiratory system or individuals exposed to irritating vapors were excluded from the study. The clinical evaluation included phoniatric examinations with use of videoendoscopy (VIS) and videolaryngostroboscopy (VLSS) of the larynx. Based on the larynx endoscopic image the voice organ pathology was diagnosed in the patients as functional and/or organic dysphonia. The former comprised hyperfunctional or hypofunctional dysphonia and insufficiency of the glottis and the latter other laryngeal disturbances. In the statistical analysis chi2 parametric test of independence for two averages was used. Female teachers of primary and lower secondary schools, mean age 43 years, prevailed in the group of professional voice users, in which functional dysphonia was more common. In this group, the onset of organic changes was earlier than that of functional changes and was manifested by soft vocal nodules, edematous and inflammatory changes in the vocal fold mucosa. Functional dysphonia of 3 degrees, 4 degrees and even 5 degrees predominated in the group of professional voice users in the course of their employment.

    [Show abstract] [Hide abstract] ABSTRACT: Occurrence of professional dysphonia was analysed in a group of 309 patients treated in the Phoniatric Outpatient Clinic, Department of Otolaryngology, Medical Academy in Białystok through the period of 1999-2001. In a group of professional voice users female teachers of primary schools and lower secondary schools predominated. Obtained results were compared with those from a group of 65 persons of other occupations. In the both groups other harmful factors affecting the voice organ were excluded. The clinical assessment included subjective and objective laryngological examination using videolaryngostroboscopy. The clinical material was evaluated in a view of functional and organic disorders of the voice organ. Early occurrence and aggravation of functional changes in the larynx was recorded in non professional voice users in the course of their seniority. In professional patients organic changes were more common and occurred earlier than functional disorders. Severity of dysphonia was related to the larynx pathology, especially of a functional character.

    [Show abstract] [Hide abstract] ABSTRACT: The observation of the glottis and the vocal fold mobility during phonation enables the diagnosis of larynx pathology. Videolaryngostroboscopy (VLSS) facilitates acquiring a precise endoscopic picture and an evaluation of the vocal fold vibratory movements. This method is recognised as an objective, repetitive and non-invasive approach to accelerate early diagnosis in laryngeal carcinoma, vocal nodules, vocal fold paresis, larynx oedema, functional dysphonia and presbyphonia. The mucosal wave is a particularly important parameter in the stroboscopic examination. The absence of mucosal wave indicates microinfiltrations in the T1 stage of glottic carcinoma and vocal hard nodules, the complete form of paretic dysphonia and the severe form of atrophic presbyphonia. The recurrent mucosal wave suggests re-innervation in the paretic dysphonia. Aberrations in the vocal fold vibrations indicate a supraepithelial oedema of the laryngeal mucosa and a functional type of dysphonia, requiring differential therapy. The larynx image recorded on a video tape is a valuable diagnostic evidence that allows monitoring of therapeutic effects and phoniatric rehabilitation.
