An extended postauricular incision has replaced the standard C-shaped scalp flap for cochlear implant surgery at our institution. The postoperative wound complication rates of the two incisions were evaluated.
This study was a retrospective case review.
This study was performed in a tertiary referral center.
A total of 256 adult and pediatric patients who underwent cochlear implantation during a 10-year period (1986 to 1996) were reviewed.
Postoperative wound complications were identified. Major complications included flap necrosis, wound dehiscence with or without implant exposure, and wound infection requiring hospitalization. Hematoma, seroma, or superficial wound infections were considered minor complications.
There were 6 major and 6 minor complications among 116 patients with the standard scalp flap (complication rate, 10.3%). There was only 1 minor complication among 140 implants using the postauricular incision (0.7%).
The extended postauricular incision appears to significantly reduce the incidence of wound complications in cochlear implant surgery.
在我们机构，耳后延长切口已取代标准的C形头皮瓣用于人工耳蜗植入手术。对两种切口的术后伤口并发症发生率进行了评估。
本研究为回顾性病例分析。
本研究在一家三级转诊中心进行。
回顾了10年间（1986年至1996年）接受人工耳蜗植入的256例成人和儿童患者。
确定术后伤口并发症。主要并发症包括皮瓣坏死、伤口裂开伴或不伴植入物暴露，以及需要住院治疗的伤口感染。血肿、血清肿或浅表伤口感染被视为轻微并发症。
116例采用标准头皮瓣的患者中有6例主要并发症和6例轻微并发症（并发症发生率为10.3%）。140例采用耳后切口植入的患者中仅有1例轻微并发症（0.7%）。
耳后延长切口似乎能显著降低人工耳蜗植入手术中伤口并发症的发生率。
