冠状头皮瓣径路摘除眶内肿瘤技术

The technique of coronal scalp flap approach for removal orbital tumors

眼眶中后部的球后肿瘤,由于手术不能达到肿瘤部位,造成摘除困难。采用横过头皮做冠状切口,头皮瓣向前暴露从上眶缘到颧弓的眶缘,这样整个手术野易于暴露,对累及眶尖和内侧壁、上眶部、邻近骨骼的广泛眼眶病变尤适合这一手术径路。此外,冠状头皮瓣术后较美观,并发症少。

Retrobulbar tumors within the medial orbital spaceare difficult to remove because of their somewhatinaccessible position. A Coronal incision is made acrosthe scalp. The scalp flap is developed anteriorly to ex-pose the orbital margin from the superior orbital rimto the zygomatic arch. Since the entire surgical field iswell exposed. Extensive orbital lesions that involve theapex; the interior and superior orbital walls; and contig-uous bone are particularly well suited to this surgicalapproach. In addition, the coronal scalp provides im-proved postoperative aesthetic and the complicationsare infrequent.
