本法是将柯氏手术的切口向前延长超过中线,向后则达第三磨牙之后。将颊部软组织向上剥离高达眶下缘,剪开近梨状孔处的鼻腔侧壁后,其暴露面虽略小,但能够把上颌骨较完整地切除下来,术后反应极小,除面颊有一些下陷外,损容不大。现报道1例上颌窦癌以此法进行治疗。 This method is to extend the incision of the Cooper surgery forward beyond the midline and backwards after the third molar. The buccal soft tissue was peeled up to the inferior orbital edge. After cutting the side wall of the nasal cavity near the pear-shaped hole, the exposed surface was slightly smaller, but the maxilla could be relatively completely removed. The postoperative response was minimal, except for the cheeks. There are some downsides and little damage. One case of maxillary sinus cancer is reported to be treated as such.
