Plan موضوع المحاضره التعريف بزراعه القوقعه الفئات المستهدفه لزراعه شروط زراعه القوقعه Definition of cochlear implant Candidates for implantation Requirements of cochlear implant Causes of limited results اسباب محدودية النتائج

تعريف بزراعة القوقعه عباره عن جهاز الكتروني يوضع في الاذن الداخليه على منطقه الشعيرات السمعيه التالفه داخل القوقعه . ومهمته تحفيز العصب السمعي على العمل الكترونيا Definition : An electrical device implanted surgically in the cochlea in the Inner ear which stimulates electrically the 8th nerve to conduct to the primary hearing area in the brain Courtesy of : Susan B waltzman , Noel L cohen , Cochlear implant surgery

Candidates for implantation Non – benefitting patients from hearing Aids : 1- Pre – lingual period of Age ( 0-4 ) years suffering from bilateral sensory profound hearing loss . 2- Bilateral traumatic sensory profound hearing loss in people having already acquired normal language . Courtesy of : Susan B waltzman , Noel L cohen , Cochlear implant surgery

الفئات المستهدفه لزراعه القوقعه المرضى غير المستفيدين من المعينات السمعيه ( السماعات الطبيه ) تقسم الى فئتين : 1- الفئه العمريه 0-4 سنوات (فتره الاكتساب اللغوي) , التي تعاني من ضعف سمع حسي شديد الى شديد جدا في كلتا الاذنين شريطة وجود عصب سمعي سليم . 2- الفئه العمريه ما بعد اكتساب اللغه والتي تعاني من ضعف سمع شديد الى شديد جدا ناتج عن اصابات و شريطة وجود عصب سمعي سليم Courtesy of : Susan B waltzman , Noel L cohen , Cochlear implant surgery

Requirements of cochlear implant having the support of family and friends No medical contra-indication for surgery living in or desiring to live in the "hearing world" having realistic expectations about results: electrical hearing external appearance of Device No MR Courtesy of : Susan B waltzman , Noel L cohen , Cochlear implant surgery

شروط زراعة القوقعة استعداد اسره المريض لمساعدته على اكتساب المهارات اللغويه و الكلاميه بعد العمليه عدم وجود سبب طبي يعيق العملية الجراحية رغبه المريض في السمع عن طريق القوقعه تفهم المريض واسرته للنتائج الفعليه الحقيقيه للعمليه : الصوت الاكتروني شكل الجهاز الخارجي للقوقعه عدم وجود مشاكل عقلية Courtesy of : Susan B waltzman , Noel L cohen , Cochlear implant surgery

Causes of limited results of cochlear implant in deaf adolescents Poor Brain capability to acquire spoken language due to focusing on Sign language استعمال لغة الاشارة يؤدي الى ضعف اكتساب الدماغ للغه المنطوقه Takes long time to understand what the patient hears يستغرق المريض زمنا طويلا لفهم ما يسمعه Psychological effects ( society , family , friends ) مؤثرات نفسيه ( المجتمع , الاسرة , الاصدقاء ) Courtesy of : Susan B waltzman , Noel L cohen , Cochlear implant surgery

Conclusion Having realistic expectations about results Follow – up mapping By Audiologist Post – surgical rehabilitation by AVT , speech therapy to overcome the discrimination of hearing language NO use of Sign language NO CI for benefitting patients From H.A’s NO CI for post – lingual patients depending on sign language

الخلاصه يجب ان يتقبل الاهل الشكل الخارجي للقوقعة ونوعية الصوت الالكتروني القوقعة الاصطناعية بحاجة لمتابعة التعيير وهذا من مهام اختصاصي السمع لتاهيل المرضى بعد زراعة القوقعة تدريب نطقي لفظي , لتجاوز مشكلة عدم الاستيعاب والتمييز اللغوي عند زراعة القوقعة عدم استخدام لغة الاشارة مع المريض لا تزرع القوقعة لمن عندهم القابلية للاستفادة من المعينات السمعية لا تزرع القوقعة لمن هم فوق سن ال 5 سنوات ولا يوجد لديهم اي اكتساب لغوي سمعي و يعتمدون على لغة الاشارة
