A case of bilateral coronoid enlargement resulting in restricted opening of the mandible has been presented, and the literature has been reviewed. This case brings the total number of reported cases to 36. As in the majority of the previous cases, this patient was male, and the abnormality was first noticed at the onset of puberty. The radiologic features were diagnostic: the restricted mandibular motion was secondary to coronoid process impingement on the posterior aspect of the zygomatic bones. A large exostosis had appeared on the left humerus at approximately the same time as the onset of the limitation of mouth opening. The patient refused surgery because he did not believe that the abnormality caused any significant functional impairment.
本文报告了一例双侧冠状突增大导致下颌骨开口受限的病例，并对相关文献进行了综述。该病例使报告的病例总数达到36例。与大多数先前病例一样，该患者为男性，异常情况在青春期开始时首次被发现。放射学特征具有诊断意义：下颌运动受限是由于冠状突撞击颧骨后侧所致。在张口受限开始的大致同一时间，左侧肱骨出现了一个大的骨疣。患者拒绝手术，因为他认为这种异常不会造成任何明显的功能损害。
