Resecting neoplasms involving the infratemporal space has a high risk of damaging critical nerves and vessels, in addition to joint form and function. The purpose of this study was to introduce a novel approach to lesions medial to the condyle, which comprises a condylectomy with anterior displacement of the condyle. The indications evaluated using digital surgical simulation, the critical surgical technique, and the preliminary clinical effects are presented here. Five cases underwent this approach between January 2006 and December 2014. The common characteristics of the five masses were (1) that they were non-malignant neoplasms involving the posterior-medial region of the condyle; (2) the upper and lower borders were between the skull base and the lingula, while the anterior border did not exceed the coronoid process. All masses were resected successfully with no damage to any critical nerves or vessels. The average follow-up period was 29.8 months (range 6-56 months). There was no recurrence, secondary deformity, or facial paralysis. The average mouth opening improved from an original 27 mm to 34 mm after surgery. The condyles were well fixed, with no resorption, as shown on computed tomography scans.
除了关节形态和功能外，切除累及颞下间隙的肿瘤还存在损伤重要神经和血管的高风险。本研究的目的是介绍一种治疗髁突内侧病变的新方法，该方法包括髁突切除术及髁突向前移位。本文介绍了使用数字手术模拟评估的适应证、关键手术技术及初步临床效果。2006年1月至2014年12月期间，5例患者接受了该手术方法。这5个肿物的共同特征为：（1）均为累及髁突后内侧区域的非恶性肿瘤；（2）上下边界位于颅底和舌骨之间，而前边界未超过冠突。所有肿物均成功切除，未损伤任何重要神经或血管。平均随访期为29.8个月（范围6 - 56个月）。无复发、继发畸形或面瘫。术后平均开口度从术前的27 mm改善至34 mm。计算机断层扫描显示髁突固定良好，无吸收。
