耳蜗植入设备

 

Evaluation generally takes two days. 您的听力学家将详细讨论人工耳蜗装置的组成部分, 其功能, benefits and limitations as well as the surgical process. 对儿童和成人的评估略有不同，包括以下内容:

• 医疗评估-由植入外科十大赌博平台排行榜进行，他会记录你的病史, examine your ears and explain the surgical process to you. Implant surgeons are part of the Otolaryngology department at 加州大学旧金山分校健康.
• CT扫描——这种计算机断层扫描(CT)会产生内耳的二维x射线. It allows the surgeon to evaluate the ear's internal structure, 建议植入哪只耳朵，并可能提供耳聋原因的信息.
• 听力学评估——这种评估包括听力测试，以确认听力损失的类型和程度, 助听器评估:评估助听器提供的好处，辅助语音识别测试，以确定助听器是否比植入物提供更大的好处.
• 心理筛查——这种筛查是由加州大学旧金山分校耳聋中心的心理学家进行的，目的是评估你对听力损失和人工耳蜗植入的感受, such as your reasons for seeking the implant and your expectations.
• Cochlear Implant Counseling — At this time, you will find out if you qualify for an implant, based on the results of the entire evaluation. 如果你有资格, 我们将解释可能的好处和限制，并为您提供选择设备的信息.
• School Visit — 对孩子来说, 学校访问的目的是与他或她的学校建立持续的关系, 教师和治疗师在植入手术之前，并提供在职培训的专业人员与您的孩子一起工作，以确保相互支持和共同的目标.

手术

手术前, 你将会见麻醉师和十大赌博平台排行榜的收纳人员，并完成所有必要的检查. Tours of the hospital also can be arranged. 手术 usually is performed the following day.

患者通常在十大赌博平台排行榜过夜，手术后第二天回家.

植入手术在全身麻醉下进行，大约需要三个小时. 操作过程中, 外科十大赌博平台排行榜将在颅骨的颞骨内固定一个接收器-刺激器装置，并将所谓的“电极阵列”插入耳蜗, 耳蜗内耳中包含听觉器官的小蜗牛状结构.

First, an incision is made behind the ear to expose the temporal bone. The surgeon then positions the implant component against the bone. A hole is made in the temporal bone with a microscopic drill, allowing the surgeon access to the cochlea. 在耳蜗壁上打一个小洞，电极阵列被轻轻地引导进入耳蜗.

用缝线将内接收器固定在颅骨上，并关闭切口. A sterile dressing is placed on the incision.

To qualify for a cochlear implant, patients must meet the following criteria:

Adults age 18 and older have:

• 整体健康
• Severe hearing loss in both ears
• Limited benefit from conventional hearing aids determined by a trial period, 在适当的时候, 大约三个月
• Psychological and emotional stability
• Realistic expectations of the implant
• No ear conditions or other medical conditions that would interfere with surgery
• Ability to participate fully in a follow-up program

Children age 1 to 17 must have:

• 整体健康
• Severe hearing loss in both ears
• Limited benefit from conventional hearing aids
• Realistic expectations of the cochlear implant
• No ear conditions or other medical conditions that would interfere with surgery
• Family commitment to comply with all evaluations before and after surgery
• 参加术后康复和教育项目，支持人工耳蜗的使用和听力技能的发展

后续

手术后, 你需要回家四周，让肿胀和疼痛消退，切口愈合. After several days, the incision may be wet during bathing or showering.

设备编程

The externally worn speech processor is activated about four weeks after surgery. The processor converts speech into a special code for each user. The activation and programming is performed at the implant center. 每个植入物的程序都是为患者定制的，在两天的时间里大约需要6个小时.

测试

您将被要求定期返回UCSF人工耳蜗中心进行设备检查和重新评估. 在这些访问中，检查植入物和设备并测量其性能. Re-testing generally occurs at one, three and six months and one year following the initial device fitting.

Then, semi-annual or annual evaluations are performed. Each session for adults involves about three hours.

结果

人工耳蜗的好处通常会随着时间的推移而改善，但不能保证. 术后康复是人工耳蜗获益最大化的关键. Most people with these implants are able to engage in hearing activities, such as listening to a Walkman, 看电影, using a phone and participating in social activities.

Your motivation is critical to the success of the implant. We encourage our patients to:

• Use the device during all waking hours
• Listen, speak and interact with others as much as possible
• Utilize visual cues when adjusting to the implant, but gradually decrease the use of visual cues when ready
• Ask others to identify unfamiliar sounds so they become familiar
