Four cases of bilateral mandibular condylysis are presented. The condition does not appear to be included in current teaching or existing nomenclature and consists of an acquired absence of the mandibular condyles, unassociated with temporomandibular ankylosis or aural/facial anomalies. In the literature of condylar maldevelopment four published cases appear to justify reclassification as bilateral mandibular condylysis, bringing the recorded total to eight. Whereas previous writers have regarded the condition as a prenatal condylar aplasia or hypoplasia, morphanalysis studies of the four current cases have shown that the probable aetiology is postnatal local disturbance in the condylar region. The term condylysis has been chosen to emphasise the locally destructive (or lytic) mechanism which appears to be involved. Mandibular condylysis is distinguished from condylar aplasia by its non-association with aural/facial anomalies and because normal development appears to proceed until the lytic event occurs. It is further distinguished from primary and secondary condylar hypoplasia because the condyle is absent rather than small, because normal development appears to proceed until the lytic event occurs and because of its non-association with aural/facial anomalies or temporomandibular ankylosis.
本文报告了4例双侧下颌髁突溶解症。目前的教学内容或现有命名法中似乎并未涵盖这种病症，其表现为后天性下颌髁突缺失，与颞下颌关节强直或耳/面部畸形无关。在髁突发育异常的文献中，有4例已发表的病例似乎有理由重新分类为双侧下颌髁突溶解症，使记录的病例总数达到8例。以往的作者将这种病症视为产前髁突发育不全或发育不良，但对当前这4例病例的形态分析研究表明，其可能的病因是出生后髁突区域的局部病变。选择“髁突溶解症”这个术语是为了强调似乎涉及的局部破坏（或溶解）机制。下颌髁突溶解症与髁突发育不全的区别在于，它与耳/面部畸形无关，且在溶解事件发生之前，正常发育似乎一直在进行。它还与原发性和继发性髁突发育不良有所不同，因为髁突是缺失而非变小，正常发育似乎在溶解事件发生之前一直在进行，且与耳/面部畸形或颞下颌关节强直无关。
