[An influence of myofascial release techniques on the esophagus pressure for patients after total laryngectomy].

Unlabelled: The increase of patients after total laryngectomy myofascial neck and arms area tension might be observed. Via fascial continuity it has an adverse impact on superior oesophageal constrictor, forming the "mouth of oesophagus", which hinders learning oesophagus speech.

The Aim: The assessment of manual myofascial release techniques influence on the patients' oesophagus pressure after total laryngectomy.

Estimation of influence of myofascial release techniques on esophageal pressure in patients after total laryngectomy.

In patients after total laryngectomy, increased tension in myofascial neck and arm areas might be observed. Via fascial continuity it has an adverse impact on the superior esophageal constrictor forming the "mouth of the oesophagus", which hinders learning of esophageal speech. The aim is to assess the effect of manual myofascial release techniques on esophageal pressure in patients after total laryngectomy.

Introduction: The purpose of speech audiometry is to extend the diagnostics of central auditory processes. First audiometric tests were monaural tests introduced in the fifties by Bocca and Calearo to diagnose Central Auditory Processing Disorders (CAPD). Monaural tests are characterized by low redundancy, which allows for deciphering a given word or phrase only if the amount of accessible information exceeds a required minimum.

[Bilateral internal laryngocele with open nasality--report of a case].

Laryngocele is an abnormal saccule dilatation of the ventricle in direct communication with the laryngeal lumen. It is usually filled by air and mostly asymptomatic. This case is reported due to its rarity.

[Benign paroxysmal positional vertigo in the own material].

Introduction: The complaint of dizziness can be caused by a variety of disorders affecting central or peripheral vestibular system. Benign paroxysmal positional vertigo BPPV is the most common cause of vertigo. It is a syndrom characterized by short-lasted episodes of true vertigo, induced by a rapid head position change and associated with a positional, transient nystagmus.

[Universal neonatal hearing screening--parents view].

Unlabelled: The aim of the study was to determine the parents view and attitude to the universal neonatal hearing screening.

Material And Methods: parents of randomly selected 200 infants, who underwent hearing rescreening, were surveyed using the authors questionnaire.

Results: the universal neonatal hearing screening and the way it is conducted is accepted by the vast majority of the parents in the region of Wielkopolska.

[Polish language dychotomic tests for speech audiometry Part 2: A study of people with normal hearing from various age groups].

Introduction: Evaluation of the objective results in the clinical examination of central auditory disorders requires the use of reliable language tests which provide the means for the estimation of patients' audio-verbal communicative skills.

Materials And Methods: The authors present a new set of more difficult language tests in Polish, including a filtered speech test, numeral and verbal dichotic tests and the normal Calearo test. The tests were evaluated on a group of people with good hearing from various age groups.

[The local and sensual conditions of delay of voice breaking in adolescent boys].

Disorders of voice breaking in adolescent boys (mutational dysphonia) could be a result of local, hormonal, neuropsychiatric or sensual factors. The aim of this paper was the voice assessment of three subjects with incomplete mutation with particular additional factors, disturbing hearing, voice and speech: like hearing loss, hyperfunctional childhood dysphonia and speech dysfluency. Diagnostics included complete phoniatric examination with perceptive estimation, videostroboscopy and acoustic voice analysis, done before and after treatment.

[Subjective assessment of voice functions among teachers taking part in the rehabilitation program].

Introduction: In daily phoniatric practice, apart from laryngoscopy, another simple and useful method of examining the voice organ is perceptual voice assessment based on the GRBAS scale. An extension to this examination can be the Voice Handicap Index test (VHI).

Materials And Methods: 79 female teachers taking part in a 7-week-long rehabilitation course on voice emission techniques.

[Dychotomic tests in Polish for speech audiometry part 1: preparing material for the tests].

Introduction: Dychotomic tests in speech audiometry are extremely beneficial, especially in diagnosing central auditory processing disorders.

Materials And Methods: Basing on new articulatory lists (NLA-93), the authors have prepared a new set of language tests, including filtered speech test, numeral and verbal dichotic tests and Calearo test.

Conclusions: The phonetic characteristics of the tests are presented, with special attention paid to their phonetic balance.

[Voice disorders in recurrent laryngeal granuloma dependend on GERD].

The voice disorders in a case of recurrent laryngeal granuloma with chronic gastroesophageal reflux was described. There was emphasized necessity of complex treatment pharmacological and phoniatric, as well as there were pointed out some indications of microsurgery.

[The teachers health damage and pension related to occupational voice disease].

The current regulations allow in special cases for the acknowledgement of the occupational disease among teachers who suffer from voice disorders. The physician who acts as the adjudicator in ZUS (National Insurance System) usually consults a phoniatrician and determines the percent of the permanent or long-term health damage, which can vary between 10-40%. The aim of the paper was to analyze the evidence which is taken into consideration while determining the percent of health damage and granting the occupational disease pension.

[The characteristic of vocal fold molecular structure].

Introduction: The authors present the layer structure of the vocal fold (by Hirano) indicating at the same time its clinical usefulness in laser chordectomy.

Materials And Methods: The authors describe the structure of the basement membrane sphere, i.e.

[Effect of smoking on phonation].

The aim of this paper was presentation of voice estimation in smokers, who did not complain of voice disorders. The examination was performed in 20 patients with history of chronic tobacco using (at least 20 years). The videolaryngostroboscopy and acoustic voice analysis were performed.

[Contraindication for cochlear implantation in Wildervanck's syndrome].

A case of 4-year-old boy with Wildervanck's syndrome and associated profound sensorineural hearing loss is presented. The child was disqualified from cochlear implantation following the CT scan of petrous pyramids which revealed inner ear malformation. The authors emphasize role of CT imaging in the management of profound sensorineural hearing loss in children before final qualification for cochlear implantation.

[The auditory late potentials (P300, MMN) in central speech disorders in children].

The aim of this paper was introduction of preliminary study of late auditory evoked potentials P300 and MMN insome central communication process disorders. The investigations were performed in the group of three children with development dysphasia and pseudobulbar dyzarthria. The registration of endogenic late cognitive potentials was performed using the alternate application of stimulus of pure tones 1 and 2 kHz, and logatoms (da)-(ga).

[Complex voice assessment--Polish version of the Voice Handicap Index (VHI)].

The aim of this work was to present own modification of Jacobson's The Voice Handicap Index, the self-estimation scale of the voice as a one part of the complex voice evaluation. The VHI contains three groups of questions of physical, emotional and functional subscales, which specify complaints during phonation scored in 4 points (0-4). The presented our own modification of the VHI may be useful in everyday clinical practice.
