本文介绍了一种变通的鼻侧切开术,即鼻侧切开加上颌窦中部切除术治疗鼻腔侧壁的良性和恶性肿瘤。作者认为此术式可提供宽阔的术野,将鼻腔侧壁、眼眶中部、上颌窦中部、筛窦、筛骨水平板、额窦和肿瘤一起整块的切除;如肿瘤同时侵犯了对侧鼻腔、筛窦、额窦,甚至前颅窝,只要将切口延长,仍可将肿瘤和周围组织甚至鸡冠、双侧筛骨水平板一起整块取出。术中出血不多,术后除术腔干燥、结痂、流泪外,极少产生其他并发症。手术操作是从眶上神经处到同侧鼻孔作一切口,为防止术后内眦部疤痕牵拉移位,此处 This article presents a modified nasal resection that treats benign and malignant tumors of the nasal cavity wall by nasal dissection plus central maxillary excision. The authors believe that this procedure can provide a wide field of surgery, the nasal cavity wall, the middle of the orbit, the maxillary sinus, ethmoid sinus, ethmoid bone plate, frontal sinus and tumor together with the block resection; such as cancer while contravening the contralateral nasal cavity , Ethmoid sinus, frontal sinus, and even the anterior cranial fossa, as long as the incision extended, the tumor and the surrounding tissue can still be even crowns, bilateral sieve bone plate together with the whole block removed. Small intraoperative bleeding, postoperative dry, crusting, tearing, minimal other complications. Surgical operation is from the supraorbital nerve to the ipsilateral nostril for an incision, in order to prevent postoperative hysteroscopic scar traction shift, here
