虽然闭合复位是髁状突骨折的常见方法，但骨碎片可能愈合不良。本研究旨在探讨单侧髁状突骨折的愈合形态。我们回顾性研究了70例单侧髁状突骨折患者。对全髁骨折组、闭合复位组和观察/功能治疗组进行临床统计学分析。其中52例年龄大于16岁的患者接受闭合复位。分析闭合复位组的最大张口度、错牙合发生率以及愈合形态与Arbeitsgemeinschaft für Osteosynthesefragen分类或牙关紧闭的关系。闭合复位组和观察/功能治疗组在年龄（P= 0.008）和性别（P= 0.025）方面存在显著差异。然而，两组之间的创伤病因和伴随骨折没有显著差异。单侧骨折闭合复位后平均最大张口度为42.6± 6.1mm，仅1例（2.1%）出现错牙合畸形。在所有MacLennan分类的偏斜或更大的偏斜中，无论分类如何，上部骨折（头部和上颈部）倾向于通过球形形态愈合（P< 0.001），而下部骨折（下颈部和髁下）倾向于通过L形和外侧融合愈合（P< 0.001）。愈合形态不变组与其他组的牙关紧闭发生率差异无统计学意义（P= 0.690）。我们的研究结果阐明了闭合复位治疗单侧下颌骨髁状突骨折的病因、功能障碍和愈合形态学分类。
Although closed reduction is common for condylar fractures, bone fragments may heal improperly. This study aimed to investigate the healing morphology of unilateral condylar fractures. We retrospectively investigated 70 patients with unilateral condylar fractures. Clinico-statistical analyses were performed on the whole-condylar fracture, closed reduction, and observation/functional therapy groups. Among these patients, 52 patients aged older than 16 years underwent closed reduction. The extent of maximum mouth opening, the incidence of malocclusion, and the relationship between healing morphology and Arbeitsgemeinschaft für Osteosynthesefragen classification or trismus were analyzed in the closed reduction group. There were significant differences in age (P= 0.008) and sex (P= 0.025) between the closed reduction and observation/functional therapy groups. However, there were no significant differences in trauma etiologies and concomitant fractures between the 2 groups. The average maximum mouth opening extent for unilateral fractures after closed reduction was 42.6±6.1 mm. Only 1 case (2.1%) of post-treatment malocclusion was observed. In all the MacLennan classification of deviation or more, regardless of the classification, upper fractures (head and upper neck) tended to heal through a spherical (P< 0.001) morphology, whereas lower fractures (lower neck and subcondylar) tended to heal through an L-shaped and lateral fusion (P< 0.001). There was no significant difference in the incidence of trismus between the healing morphology of unchanged type and others (P= 0.690). Our results elucidated the etiology, dysfunction, and healing morphology classification of unilateral mandibular condyle fractures treated with closed reduction.
