The etiology of unilateral condylar hyperplasia is obscure. We believe that it is due more likely to an intra-uterine influence rather than to genetic disturbances. The disorder appears to have its basis in the cartilagenous growth centre of the mandibular condyle. The clinical picture varies a great deal, depending upon the onset of the growth upset relative to the age of the patient and the rate of growth. Two cases are reported. In one patient the anomalous growth pattern was apparent particularly in the condylar neck, which showed marked elongation, thickening and angulation. In the other patient the entire condyloid process appeared proportionately enlarged. The typical clinical history is one in which the patient had been aware for many years of progressive deviation of the jaw. Pain in the T.M.J. regions is rarely the presenting symptom. With recent advances of oral surgery, restoration of malocclusion and facial disharmony can be achieved by approaches other than the traditional procedure of condylectomy.
单侧髁突增生的病因尚不清楚。我们认为，其更可能是由于子宫内的影响，而非遗传紊乱。这种疾病似乎起源于下颌髁突的软骨生长中心。临床表现差异很大，这取决于生长失调相对于患者年龄的起始时间以及生长速度。报告了两例病例。在一例患者中，异常生长模式在髁突颈部尤为明显，表现为明显的伸长、增厚和成角。在另一例患者中，整个髁突明显成比例增大。典型的临床病史是患者多年来一直意识到下颌逐渐偏斜。颞下颌关节区域疼痛很少是首发症状。随着口腔外科的最新进展，除了传统的髁突切除术外，还可以通过其他方法来恢复错牙合和面部不协调。
