人工電子耳植入術對病童急性中耳炎之影嚮

背景：急性中耳炎是孩童很常見的疾病，而對重度聽的病童，人工電子耳手術經常被採用。所以我們便須注意是否人工電子耳植入手術會增加急性中耳炎的發生率、嚴重度與內耳或顱內的感染。方法：從1991年到1997年間，針對曾裝置人工電子耳的33名病童，評估人工電子耳植入術是否對病童急性中耳炎之罹患率有影嚮。其中為19名男童，14名女童，植入年齡從2歲到8歲。結果：在術前這33名聽障病童都未曾或不知道有過急性中耳炎。在術後，追蹤12到42個月，無急性中耳炎的發生或經由人工電子耳電極而造成內耳顱內的感染發生。而在術前與術後上呼吸道感染頻率方面有2名減少，3名增加，其餘相同。發生頻率分別為每年5次及6次。同期間對照二組相同年齡分佈之正常兒童各33名，其曾得過中耳炎的孩童，發生率分別為12.1% (33名中有4名)及9.1% (33名中有3名)。結論：本次追蹤觀察統計顯示，對於好發急性中耳炎年齡層的病童而言，人工電子耳植入術並不會對急性中耳帶造成加重或甚有顱內感染的情況發生。

Background: Acute otitis media (AOM) is a common disease in childhood. Cochlear implant is an important option for the children with profound hearing impairment, enabling them to develop their auditory verbal communication skill. This paper reported the incidence and severity of AOM and even inner ear or intracranial infection following cochlear implants (Cls). Methods: From 1991 through 1997, 33 children received Cls in the Department of Otolaryngology of the Chi-Mei Foundation Hospital. Biostatistic analysis was performed regarding the occurrence rate of AOM before and after implantation. Results: The children who received implants included 19 boys and 14 girls, ranging in age from 2 to 8 years old. None of then had AOM before or after implantation. The follow-up period ranged from 12 to 42 months. There were neither inner ear nor intracranial complications noted after implantation in our study. For the majority of the children with cochlear implant, the occurrence rate of upper respiratory tract infection (URI) was similar to that before implantation. We also investigated two groups of children of similar age without implants. The AOM incidence in these two groups was 12.1% and 9.1%, respectively. Conclusions: From the current date we can draw the tentative conclusion that cochlear implants neither increase the incidence or severity of AOM nor cause inner ear even intracranial complications in children.
