Development of speech is a highly integrative process which has to incorporate harmonic functioning of many aspects such as anatomical, physiоlogical, auditory, mental, emotional and social. Anatomical-physiological bases of hearing have been well studied. Cochlear implant is recommended in subjects who do not have any significant increase of the sound through the individual hearing amplifiers or have small benefit and also in subjects whose impairment is over 90dBto 500, 1000, 2000 and 4000 Hz.The aim of this study was to estimate the development of hearing perception in subjects with prelingual hearing impairment who used cochlear implant with regards to perception and identification of sounds from external environment.The results of the Test for development of hearing perception showed progression during the follow-up period at 6, 12 and 24 months. It was concluded that the longer the cochlear implant was used, the better results were achieved.
Children with cleft palate/lip are exposed to risk for verbal communication disorders that include resonance, articulation, voice disorders, and expressive language. The aim of this paper was to evaluate the changes in the voice quality of the children with cleft palate in relation to children without anomaly. The study included 52 participants, 26 with previously corrected cleft palate / lip, and 26 respondents without anomaly who are between 3 and 6 years old. Subjective assessment of voice quality was performed by using the GRBAS scale. Perceptual scales are important in assessing the voice quality, determining the degree and severity of voice disturbance, and deciding on further clinical procedures. Although the instrumental approach to voice examination is relevant because it provides objectivity, the subjective impression in assessing voice quality is crucial. Statistical processing was performed by groups, group structure (gender and age), a certain highest value, as well as percentage participations. The results showed that 50% of the participants were diagnosed with certain changes in the voice. Children aged 3-5 years have a 2.25 times higher incidence of voice changes than children aged 6-8 years. The largest number of participants belong to group 0 - There is no change in voice quality which represents as much as 50% of the total number of patients in the first group. While "3 - Pronounced changes in the voice" were not identified in the respondents aged 3-5 years. In 50% of the total number of participants there is no change in voice quality and these are located in girls aged 3-5 years.
Hearing is one of the most important features that every human being possesses, one of the five senses along with sight, smell, taste, and touch.This function is accomplished owing to the complex mechanism of the sensory organ for hearing, the ear, and its coordination with the nervous system.The impairment of the cochlear normal function, impairment of the transduction of the mechanical acoustic signal in the synaptic activity of the auditory nerve leads to disorders of the complex ear mechanism.The aim of this study was to evaluate the speech development, that is, to assess the speechvoice development by using the Test for recognition of simple questions in the period of 6, 12 and 24 months.The results of the test for development of hearing perception showed progression during the examined period.Subjects in whom cochlear implant was placed in the younger age showed better results at the Test for recognition of simple questions and they recognized the meaning of a larger number of questions.This was statistically confirmed with calculated correlations between the age when the intervention was realized and the number of perceived simple questions at 6, 12 and 24 months postimplantation. All three correlations were negative and statistically significant.
Background: Electric stimulation of the auditory nerve via cochlear implants has made a great impact on treatment of sensory deafness. Advanced signal processing and stimulation paradigms have led to continuously improved results in speech understanding. Consequently, indication criteria have been extended to patients with profound and severe-to profound hearing loss and limited speech understanding with conventional acoustic amplification.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
