作者报道应用口腔径路联合下唇、下颌骨、舌中线切开术、软腭切开术和硬腭切除术治疗两例斜坡、上颈椎及颈髓接界(cervico medullary junction)处的病变。该径路在既往耳鼻喉科及神经外科文献中尚无报道。手术方法:全麻气管插管,测颈内静脉中心静脉压和血压,并作腰椎蛛网膜下引流。预防性气管切开术,纵形切口,保存第一、二气管环。用美蓝划线后,沿下唇、颏达舌骨水平作中线切开,分离下颌骨骨膜,拔除一枚切牙,以气动力微型矢状锯一次完成骨切开术。用电切割器沿舌中线缝切开,向后达舌会厌皱襞。再向前通过口底颌下腺导管开口间下达舌骨。沿软腭中线切开 The authors reported the use of oral pathology combined with lower lip, mandible, midline incision, soft palate incision and hard palate resection for the treatment of two lesions at the slope, upper cervical and cervicalico-medullary junction. This path has not been reported in previous ENT and neurosurgical literature. Surgical methods: general anesthesia tracheal intubation, measuring the central venous pressure and blood pressure of the jugular vein, and for lumbar subarachnoid drainage. Preventive tracheotomy, longitudinal incision, save the first and second tracheal ring. Blue line with the United States, along the lower lip, chin up hyoid level for midline incision, separation of the periosteum of the mandible, removal of a incisor, a miniature sagittal saw to complete the osteotomy. Electric cutter along the tongue line slit incision, the tongue will be meticulously 厌 向. Then forward through the mouth of the submandibular gland catheter opening hyacinth. Cut along the midline of the soft palate
