The aim of this study was to evaluate long-term results of treatment by intraoral coronoidotomy and prolonged physiotherapy in five patients with mandibular coronoid process hyperplasia. Five consecutive cases of coronoid process hyperplasia were studied (two unilateral and three bilateral) at the Department of Maxillo-facial Surgery of the University of Turin during the period 1985-1990. All patients were treated by intraoral coronoidotomy and given physiotherapy from the third postoperative day. This continued for an entire year. A clinical and radiological follow-up (average 39.4 months), in three cases over a 5-year period, was completed. Three months after the operation, all patients had achieved satisfactory improvement in mandibular interincisal opening. The mean value for mouth opening at the end of follow-up was 42 mm. Radiographic follow-up showed the presence of a coronoid process almost the size of the original, apparently united with the mandibular ascending ramus, with moderate dislocation and inclination posterior to the body of the zygomatic bone. The results of this study indicate that treatment of coronoid process hyperplasia by intraoral coronoidotomy, when combined with prolonged postoperative physiotherapy, gives satisfactory and stable long-term results in the correction of coronoid-malar interference.
本研究的目的是评估经口冠突切除术联合长期物理治疗对5例下颌冠突增生患者的长期治疗效果。1985年至1990年期间，在都灵大学颌面外科对连续5例冠突增生病例（2例单侧，3例双侧）进行了研究。所有患者均接受经口冠突切除术，并从术后第3天开始接受物理治疗，持续一整年。对3例患者进行了为期5年的临床和影像学随访（平均39.4个月）。术后3个月，所有患者的下颌切牙间开口度均得到了满意改善。随访结束时的平均开口度为42mm。影像学随访显示存在一个几乎与原始冠突大小相同的冠突，显然与下颌升支相连，在颧骨体后方有中度移位和倾斜。本研究结果表明，经口冠突切除术联合术后长期物理治疗，在纠正冠突-颧骨干扰方面能取得满意且稳定的长期效果。
