摘　　要：目的 :提出一种经髁突及盘后附着进路,归纳该术式的适应证、手术要点和评价临床效果。方法 :2006—2014年对5例位于颞下颌关节(TMJ)旁肿物采用上述进路。5例肿物符合以下条件—累及髁突后内侧颞下间隙较大的包膜完整的非恶性肿物,计算机模拟手术示单纯髁突离断旋转或后移无法充分暴露肿物。结果:5例肿物均得以彻底切除,未损伤重要神经,未输血。5例病例平均随访30个月,未见复发迹象。术后无继发牙颌面畸形,神经功能正常。随访时开口度平均为34 mm,均较术前有所增加(术前开口度平均为27 mm),CT示髁突固定良好,无吸收。结论:经髁突和盘后附着进路适于切除累及髁突后内侧较大的非恶性肿物,计算机设计和模拟手术有助于选择进路和适应证。PURPOSE： To introduce a novel transcondylar approach and discuss its indications, surgical procedures and preliminary clinical effects. METHODS： The novel approach was used in 5 cases from January 2006 to December 2014.The common characteristics of the 5 masses were： 1non-malignant encapsulated neoplasm involving the postero-medial region to the condyle; 2 surgical exposure was incomplete by rotating or moving backward of the condyle based on the digital surgical simulation. RESULTS： All masses were resected successfully by using the novel approach with no damage to the critical nerves and vessels. The average follow-up period was 29.8 months（range 6-56 months）. No recurrence,secondary deformity or facial paralysis were found. The average of mouth opening was improved from 27 mm to 34 mm after surgery. The condyles were fixed well with no resorption shown on CT scans. CONCLUSIONS： The transcondylar approach combined with posterior disc attachment release could be used for resection of non-malignant neoplasms involving the postero-medial region to the condyle. 3D reconstruction of CT and surgical simulation can help to determine the indications.
