在曾行乳突根治术的患者,血供是耳道壁重建的关键。介绍再生血管的耳道壁修复获满意效果。方法:①瓣的制作,从耳屏上沿发际向后下直达乳突尖平面作一耳后切口,不切骨膜,从乳突颅骨膜浅层分离软组织上达颞肌下缘,如果需要Popper或Palva瓣,在切缘下向后沿颅骨膜上平行分离,掀起颞肌下限,分离颞肌筋膜后下连接处,可见颞中血管束在颞肌下平行向后上走行。向旁牵开该肌,根据所需瓣的大小切至骨面,
In patients with radical mastectomy, blood supply is the key to reconstructing the canal wall. Describe the regenerative vascular ear canal repair satisfactory results. Methods: ① flap production, from the tragus along the hairline back to the mastoid sharp plane for a posterior incision, not periosteal, soft tissue from the mastoid skull superficial separation of the temporal muscle up, if necessary Popper or Palva flap, parallel to the skull periosteal margin under the cutting edge parallel separation, set off the lower limit of the temporal muscle, the posterior temporal fascia separation of the junction, we can see the temporal vascular bundle walking parallel to the temporal muscle. Draw aside the muscle to the side, according to the size of the required flap cut to the bone surface,
