ABSTRACT
Objective To explore the clinical value of ITMAIS in the early prelingual auditory development (EPLAD)assessment for bilateral profound hearing impaired children with hearing aids.Methods Profound sensorineural hearing impaired children fitted with hearing aids during October 2008 and July 2011 in our center were recruited in this retrospective study, and they would be tested with the ITMAIS at baseline, 3 months, and 6 months after hearing aids fitting.A total of 51 children were recruited in the study, and divided into 2 age groups according to the age at fitting, 1 yr group (28 children) and 2 yrs group (23 children).Results The EPLAD of children in both groups improved significantly in the first half of year after fitting (P<0.05).The mean EPLAD levels of children in both groups were close to or achieved the mean level of severe sensorineural hearing impaired children without intervention when they had had the hearing aids for 6 months.Conclusion Hearing aids could help the children with profound sensorineural hearing loss to improve the abilities of EPLAD.ITMAIS is a simple, an effective tool for assessing the early outcome of children with hearing aids, especially for the children who could not cooperate with the behavioral hearing test.
ABSTRACT
Objective To evaluate auditory and speech development longitudinally over the first year after co-chlear implantation in prelingual deaf pediatric cochlear implant (CI) recipients .Methods Meaningful auditory inte-gration scale (MAIS) and infant-toddler meaningful auditory integration scale (ITMAIS) were used to evaluate 34 prelingual deaf children between 14 month and 5 years and 10 month before CI and 3 ,6 ,and 12 months after im-plantation .The effects of genders ,age at implantation ,and duration of post -implantation time were evaluated .Re-sults Three MAIS scores were displayed :total ,detection ,and perception .Each score from all the subjects was significantly improved than that before cochlear implantation ,and still getting further better with CI use(P0 .05) .Conclusion After cochlear im-plantation ,a significant increase in auditory capability occurred ,especially in the first 3 months .The factor of gen-der was no influence on auditory development .These results provide preliminary validation of MAIS/IT -MAIS for evaluation of pre -lingual deaf pediatric CI recipients .
ABSTRACT
Os hormônios tireoideanos controlam a proliferação e regulam a diferenciação dos neurônios, além de atuarem no processo maturacional dos sistemas auditivo e vestibular. A literatura evidencia que alterações hormonais da glândula tireóide podem comprometer as estruturas vestíbulos-cocleares periféricas e centrais. O presente trabalho teve como objetivo verificar, na literatura das ultimas décadas, as alterações do sistema vestíbulo-coclear decorrentes de modificações no funcionamento da glândula tireóide. As alterações na produção dos hormônios da tireóide, tanto adquiridas quanto congênitas, afetam a orelha média, o sistema vestíbulo-coclear e a via auditiva central. Assim, para auxiliar na elucidação do diagnóstico etiológico, sugere-se incluir a investigação de alterações hormonais da tireóide na entrevista com o paciente com queixa de alteração auditiva e/ou do equilíbrio.
Thyroid hormones control the proliferation and regulate the differentiation of neurons, as well as they act on maturational process of auditory and vestibular systems. Literature shows that thyroid gland alterations can affect central and peripheral vestibulocochlear structures. The aim of this revision of the last decade literature was to verify the auditory and balance structures alterations caused by modifications on the thyroid gland active. Acquired and congenital alterations on thyroid hormones production affect middle ear, vestibulocochlear system and central auditory pathway. So, to assist the etiological diagnosis explanation, we suggest the inclusion of thyroid hormones alterations inquiry during interview with that patient who have auditory and/or balance alterations complaint.
