BACKGROUND/AIM: This study evaluates anatomical reduction and rigid internal fixation of mandibular condyle fractures using the preauricular retroparotid approach. It also discusses advantages, deficiencies, and associated complications of the technique.
This retrospective study reviewed the medical records of a total of 52 mandibular condyle fractures from 42 patients who were treated with open surgery using the preauricular retroparotid approach between January 2019 and January 2024. Preoperative and postoperative assessments included measurements of mouth opening (maximum interincisal distance), vertical mandibular movement, and facial paralysis. Moreover, the Vancouver Scar Scale (VSS) was used to evaluate scar quality at the surgical site. Descriptive statistics were used to summarize patient demographics, preoperative findings, and postoperative outcomes.
Anterior open bite was the most common finding, detected in 83% of the patients before surgery. The mean mouth opening of the patients increased significantly from 29 ± 4.94 mm to 37.76 ± 2.12 mm. Vertical mandibular movement exceeding 4 cm was a finding in more than half (52.3%) of the patients. The mean VSS score, indicating scar quality, was 1.64 ± 0.70, suggesting overall good cosmetic outcomes. Plate breakage in two patients was noted as a complication during follow-up.
Several surgical techniques have been described for mandibular condyle fractures, each with its own benefits and limitations.
背景/目的：本研究评估了经耳前腮腺后入路对下颌骨髁突骨折进行解剖复位和刚性内固定的效果。还讨论了该技术的优点、缺点和相关并发症。
这是一项回顾性研究，共纳入了 42 例患者的 52 例下颌骨髁突骨折病例，这些患者均于 2019 年 1 月至 2024 年 1 月期间采用经耳前腮腺后入路行开放手术治疗。术前和术后评估包括开口度（最大切牙间距）、下颌垂直运动和面瘫的测量。此外，还采用温哥华瘢痕量表（VSS）评估手术部位的瘢痕质量。采用描述性统计来总结患者的人口统计学资料、术前发现和术后结果。
术前最常见的发现是前牙开颌，占 83%的患者。患者的开口度从术前的 29 ± 4.94mm 显著增加至术后的 37.76 ± 2.12mm。超过一半（52.3%）的患者存在垂直下颌运动超过 4cm 的情况。代表瘢痕质量的平均 VSS 评分为 1.64 ± 0.70，提示整体美观效果良好。两名患者在随访期间出现了钢板断裂的并发症。
已经描述了几种用于下颌骨髁突骨折的手术技术，每种技术都有其优点和局限性。
