Abstract
Description
Invenţia se referă la medicină, în special la otorinolaringologie, şi poate fi utilizată pentru aprecierea inteligibilităţii vocale. The invention relates to medicine, in particular to otorhinolaryngology, and can be used for assessing voice intelligibility.
Este cunoscută metoda de evaluare a auzului - audiometria vocală, care constă în aceea că prin căştile de telefon, vibratorul osos sau prin difuzoare în câmp liber sonor sunt emise testele vocale la intensităţi diferite, constituite din liste a câte 10 cuvinte, înregistrate pe o bandă magnetică, pe CD sau computer. Rezultatele se notează pe un grafic, în care pe abscisă sunt notate intensităţile semnalului-test măsurat în decibeli (dB), iar pe ordonată sunt înscrise valorile pentru inteligibilitate, valori care reprezintă procentul de cuvinte corect reproduse de către pacient [1]. The method of hearing assessment is known - vocal audiometry, which consists in that through telephone headphones, bone vibrator or loudspeakers in a free sound field, vocal tests are emitted at different intensities, consisting of lists of 10 words, recorded on a magnetic tape, CD or computer. The results are noted on a graph, in which the intensities of the test signal measured in decibels (dB) are noted on the abscissa, and the values for intelligibility are written on the ordinate, values that represent the percentage of words correctly reproduced by the patient [1].
Dezavantajul metodei constă în faptul că necesită audiometre specializate, aparataj sofisticat de calibrare, teste de audiometrie vocală cu specificul de dialect, timp indelungat de efectuare, dificultatea de efectuare la copii, vârstnici. The disadvantage of the method is that it requires specialized audiometers, sophisticated calibration equipment, dialect-specific vocal audiometry tests, long time to perform, and difficulty performing in children and the elderly.
În acelaşi timp, pentru stabilirea diagnosticului topografic al patologiilor auditive şi selecţia individuală adecvată ale protezelor auditive, este important de a stabili scorul maxim de inteligibilitate prin utilizarea testelor vocale. Astfel, devine oportună aplicarea unor noi principii de determinare a indicelui respectiv. At the same time, for establishing the topographic diagnosis of auditory pathologies and the appropriate individual selection of hearing aids, it is important to establish the maximum intelligibility score using voice tests. Thus, it becomes appropriate to apply new principles for determining the respective index.
Problema pe care o rezolvă invenţia propusă constă în majorarea eficacităţii diagnosticului audiologic prin utilizarea unei metode mai operative şi simple de determinare a scorului maxim de inteligibilitate vocală. The problem solved by the proposed invention consists in increasing the effectiveness of audiological diagnosis by using a more operative and simple method of determining the maximum speech intelligibility score.
Avantajul constă în obiectivizarea determinării scorului maxim de inteligibilitate vocală. Metoda propusă permite diagnosticul în lipsa testelor specifice de audiometrie vocală, nu necesită aparataj suplimentar, durează mai putin timp, fapt ce ulterior este important în iniţierea mai rapidă a programului de tratament şi de reabilitare a persoanelor cu handicap auditiv. The advantage lies in the objectivity of determining the maximum speech intelligibility score. The proposed method allows diagnosis in the absence of specific speech audiometry tests, does not require additional equipment, takes less time, which is subsequently important in the faster initiation of the treatment and rehabilitation program for people with hearing disabilities.
Matematic problema se reduce la deducerea unei formule, în baza analizei datelor audiometriei tonale, care permite a determina scorul maxim de inteligibilitate (dB) ţinând cont de rezultatele audiometriei tonale liminare şi supraliminare. Folosirea analizei de regresie la prelucrarea datelor statistice despre pacienţii investigaţi ne-a permis să deducem o formulă care reprezintă esenţa metodei de determinare. Deducerea ecuaţiei de regresie din datele audiometriei tonale la 32 de pacienţi s-a efectuat folosind programul - Pachet Statistic pentru Ştiinţe Sociale (SPSS). Mathematically, the problem is reduced to deducing a formula, based on the analysis of pure tone audiometry data, which allows determining the maximum intelligibility score (dB) taking into account the results of threshold and suprathreshold pure tone audiometry. The use of regression analysis in processing statistical data on the investigated patients allowed us to deduce a formula that represents the essence of the determination method. The deduction of the regression equation from pure tone audiometry data in 32 patients was carried out using the program - Statistical Package for Social Sciences (SPSS).
Esenţa metodei de determinare a scorului maxim de inteligibilitate vocală constă în aceea că se efectuează examinarea audiometrică tonală cu stabilirea următorilor parametri: media pragului auditiv (PA), media pragului de disconfort (PD), aspectul curbei audiometrice (CA), indicele de articulare (IA), media gradului de surditate (GS), apoi în baza rezultatelor obţinute se calculează scorul maxim de inteligibilitate vocală (y), conform formulei: The essence of the method for determining the maximum voice intelligibility score consists in performing a tonal audiometric examination with the establishment of the following parameters: average hearing threshold (PA), average discomfort threshold (PD), aspect of the audiometric curve (CA), articulation index (IA), average degree of deafness (GS), then based on the results obtained, the maximum voice intelligibility score (y) is calculated, according to the formula:
y = 0,784xPA + 0,230xPD - 1,192xCA - 0,214xIA - 0,590xGS + 51,055. y = 0.784xPA + 0.230xPD - 1.192xCA - 0.214xIA - 0.590xGS + 51.055.
Un scor maxim de inteligibilitate vocală înregistrat până şi inclusiv la 40 dB este caracteristic pentru un auz normal. Un scor maxim înregistrat la valori mai mari de 40 dB este caracteristic pentru hipoacuzie. A maximum speech intelligibility score recorded up to and including 40 dB is characteristic of normal hearing. A maximum score recorded at values greater than 40 dB is characteristic of hearing loss.
Prin metoda elaborată se facilitează diagnosticul patologiilor auditive şi programul individual de recuperare protetică. The developed method facilitates the diagnosis of auditory pathologies and the individual prosthetic recovery program.
Rezultatul constă în majorarea eficacităţii diagnosticului audiometric printr-o metodă mai efectivă, operativă şi ieftină. The result is to increase the effectiveness of audiometric diagnosis through a more effective, efficient and inexpensive method.
Pragurile de auz la efectuarea audiometriei tonale se determină conform conductibilităţii aeriene şi osoase, separat pentru fiecare ureche. Audiometria tonală liminară începe cu prezentarea sunetului continuu la o intensitate confortabilă, la frecvenţa de 1000 Hz (fiind frecvenţa cea mai uşor de identificat, primordială zonei de conversaţie). Ulterior se descreşte în paşi a câte 10 dB până când pacientul nu mai răspunde şi de aici se începe determinarea pragului de auz. Se creşte în paşi a câte 5 dB, pe 2…3 s, până când pacientul răspunde din nou. Examinarea se repetă de 2…3 ori. Se examinează ulterior frecvenţele de 2000, 4000, 6000, 8000 Hz, apoi de 500, 250, 125 Hz. Examinarea se finalizează cu determinarea repetată a pragului auditiv la frecvenţa de 1000 de Hz. La determinarea pragului de disconfort (audiometria tonală supraliminară) pacientul este instruit că intensitatea sunetului se va mări progresiv; când sunetul devine neplăcut (foarte greu de suportat) trebuie să ridice mâna sau să apese butonul. Investigaţia se efectuează la frecvenţele de 500, 1000, 2000, 4000 Hz la ambele urechi. Începând de la nivelul perceperii, sunetul este treptat mărit până la primirea răspunsului de senzaţie neplăcută. La necesitate se efectuează mascarea urechii controlaterale. Timpul mediu de efectuare a audiometriei tonale este de 15…20 min. Rezultatele sunt fixate pe blancul audiogramei. Hearing thresholds when performing pure tone audiometry are determined according to air and bone conduction, separately for each ear. Pure tone audiometry begins with the presentation of continuous sound at a comfortable intensity, at a frequency of 1000 Hz (being the most easily identifiable frequency, primordial to the conversation zone). Subsequently, it is decreased in steps of 10 dB until the patient no longer responds and from here the hearing threshold determination begins. It is increased in steps of 5 dB, for 2…3 s, until the patient responds again. The examination is repeated 2…3 times. The frequencies of 2000, 4000, 6000, 8000 Hz are subsequently examined, then 500, 250, 125 Hz. The examination is completed with the repeated determination of the hearing threshold at a frequency of 1000 Hz. When determining the discomfort threshold (suprathimal tone audiometry), the patient is instructed that the sound intensity will increase progressively; when the sound becomes unpleasant (very hard to bear) he must raise his hand or press the button. The investigation is performed at frequencies of 500, 1000, 2000, 4000 Hz in both ears. Starting from the level of perception, the sound is gradually increased until the unpleasant sensation response is received. If necessary, the contralateral ear is masked. The average time for performing tone audiometry is 15…20 min. The results are fixed on the audiogram blank.
Scorul maxim de inteligibilitate vocală, adică 100% de inteligibilitate a testelor audiometriei vocale, se determină atât prin efectuarea audiometriei vocale descrise anterior (timpul mediu de efectuare a audiometriei vocale a fost de 25…30 min), cât şi prin evaluarea următorilor indici ai audiometriei tonale liminare şi supraliminare: media pragului auditiv (PA), media pragului de disconfort (PD), aspectul curbei audiometrice (CA), indicele de articulare (IA) şi media gradului de surditate (GS). Diferenţa dintre scorul maxim de inteligibilitate pronosticat şi cel real (diferenţa dintre valoarea reală şi cea pronosticată), cuprinsă între limitele 0…5,00%, este considerată excelentă; >5,00 …10,00% - bună; >10% - joasă. The maximum speech intelligibility score, i.e. 100% intelligibility of speech audiometry tests, is determined both by performing the previously described speech audiometry (the average time for performing speech audiometry was 25…30 min), and by evaluating the following indices of threshold and suprathreshold tone audiometry: average hearing threshold (PA), average discomfort threshold (PD), aspect of the audiometric curve (CA), articulation index (IA) and average degree of deafness (GS). The difference between the predicted and actual maximum speech intelligibility score (the difference between the actual and predicted value), between the limits of 0…5.00%, is considered excellent; >5.00 …10.00% - good; >10% - low.
La persoanele cu auz normal scorul maxim de inteligibilitate vocală (100%) nu trebuie sa depăşească 40 dB. In people with normal hearing, the maximum speech intelligibility score (100%) should not exceed 40 dB.
Exemplu de realizare a invenţiei Example of embodiment of the invention
Pacientul N., 12 ani, diagnosticul - surditate neurosenzorială bilaterală, formă moderată. Audiometria tonală a fost efectuată în decurs de 15 min, audiometria vocală a fost efectuată în decurs de 25 min. Analiza audiometriei tonale liminare şi supraliminare efectuată automat a stabilit următorii indici: aspectul curbei audiometrice (CA) - descendent; media pragului auditiv stabilit la audiometria tonală (PA) - 45 dB; media gradului de surditate stabilit la audiometria tonală (GS) - 48 dB; media pragului de disconfort (PD) - 101,25 dB, indicele de articulare (IA) - 23%. Scorul maxim de inteligibilitate în cadrul audiometriei vocale de 100% a fost stabilit la intensitatea de 75 dB, caracteristic pentru hipoacuzie. La utilizarea formulei matematice elaborate pentru pronosticarea scorului maxim de inteligibilitate s-a obţinut valoarea de 75,19 dB, diferenţa dintre valoarea reală şi cea pronosticată constituind 0,25%, ce reprezintă un indiciu favorabil. Patient N., 12 years old, diagnosis - bilateral sensorineural deafness, moderate form. Pure tone audiometry was performed within 15 min, vocal audiometry was performed within 25 min. Analysis of pure tone liminal and supraliminal audiometry performed automatically established the following indices: aspect of the audiometric curve (CA) - descending; average hearing threshold established at pure tone audiometry (PA) - 45 dB; average degree of deafness established at pure tone audiometry (GS) - 48 dB; average discomfort threshold (PD) - 101.25 dB, articulation index (IA) - 23%. The maximum intelligibility score within vocal audiometry of 100% was established at the intensity of 75 dB, characteristic of hearing loss. When using the mathematical formula developed to predict the maximum intelligibility score, the value of 75.19 dB was obtained, the difference between the real and predicted value being 0.25%, which represents a favorable indication.
Investigaţiile au fost efectuate în cadrul Laboratorului şi Catedrei de otorinolaringologie a USMF ”N.Testemiţanu” pe un lot de 32 de copii de varstă şcolară şi adulţi cu surditate neurosenzorială bilaterală. S-a efectuat examenul clinic primar (inclusiv statutul ORL), acumetria fonică, audiometria tonală şi audiometria vocală. The investigations were carried out within the Laboratory and Department of Otorhinolaryngology of the "N. Testemiţanu" University of Medicine and Pharmacy on a group of 32 school-age children and adults with bilateral sensorineural deafness. The primary clinical examination (including ENT status), phonic acumetry, tonal audiometry and vocal audiometry were performed.
Controlul modelului propus pe date reale (51 de urechi examinate) a permis să constatăm că o eroare ce nu depăşeşte 5% din valoarea reală constituie 54,9%, iar o eroare care nu depăşeşte 10% din valoarea reală - 94,1% din numărul de urechi investigate. Checking the proposed model on real data (51 ears examined) allowed us to find that an error that does not exceed 5% of the real value constitutes 54.9%, and an error that does not exceed 10% of the real value - 94.1% of the number of ears investigated.
Indicaţie pentru utilizarea acestei metode constituie diagnosticul audiologic la pacienţii cu surditate, pentru întocmirea ulterioară a planului de tratament şi reabilitarea electroacustică a auzului. The indication for using this method is audiological diagnosis in patients with deafness, for the subsequent preparation of the treatment plan and electroacoustic rehabilitation of hearing.
Metoda propusă de determinare a scorului maxim de inteligibilitate vocală, care include analiza investigaţiilor audiometriei tonale şi utilizarea unei formule matematice, permite stabilirea diagnosticului adecvat în lipsa testelor specifice de audiometrie vocală şi a aparatajului suplimentar costisitor şi sofisticat, totodată metoda este mai rapidă, ceea ce este important pentru iniţierea programului de tratament şi reabilitare a persoanelor cu handicap auditiv. The proposed method for determining the maximum speech intelligibility score, which includes the analysis of pure tone audiometry investigations and the use of a mathematical formula, allows for the establishment of an adequate diagnosis in the absence of specific speech audiometry tests and additional expensive and sophisticated equipment. At the same time, the method is faster, which is important for initiating the treatment and rehabilitation program for people with hearing disabilities.
