Zygomatico-coronoid fibrous ankylosis of the mandible is a complication which rarely occurs if fractures of the middle third of the facial skeleton have been adequately treated. 379 zygomatic fractures in hospitalized patients were treated at the Department of Jaw Surgery of the Surgical Hospital in Helsinki between 1969 and 1975. 36 cases were characterized by convalescence being complicated by significant restriction of jaw opening. 25 patients were successfully treated by physiotherapy and 6 other by a forced opening of the jaws under general anaesthesia. In the remaining 5 cases 91.3% of the fractures) the clinically verified fibrous extra-articular ankylosis was resistant to the above mentioned conservative methods and was treated instead by intraoral coronoidectomy, supplemented in one instance by a partial myotomy of the affected masseter muscle. The importance of prophylactic physiotherapy is stressed and applies to both the post-accident and the post-corrective-operation period.
下颌骨颧突 - 冠突纤维性关节强直是一种并发症，若面部骨骼中三分之一处的骨折得到充分治疗，则很少发生。1969年至1975年间，赫尔辛基外科医院颌外科对379例住院患者的颧骨骨折进行了治疗。36例患者的康复过程因明显的张口受限而复杂化。25例患者通过物理治疗成功治愈，另外6例在全身麻醉下通过强行张口治愈。在其余5例（占骨折病例的91.3%）中，经临床证实的关节外纤维性关节强直对上述保守方法有抗性，改为经口冠突切除术治疗，其中1例辅以患侧咬肌部分肌切开术。强调了预防性物理治疗的重要性，这适用于事故后和矫正手术后阶段。
