Objective: To analyse the quality of life of patients receiving repair of bone defect with folded fibula flap after removal of mandibular ameloblastoma. Methods: The case data of 39 patients with ameloblastoma admitted to the First Affiliated Hospital of Zhengzhou University from August 2013 to April 2016 were retrospectively analysed, including 21 males and 18 females, from 18 to 58 years old. 3D printing and digital technology were used in flap preparation before surgery in all patients. The folded fibular flaps were used to repair mandibular defects and the implants were placed between 6-9 months after surgery. The short form-36 health survey questionnaire (SF-36) and the university of Washington quality of life questionnaire (UW-QOL) were applied to evaluate the quality of life of patients before surgery and at 6 months and 24 months after surgery. The higher the score, the better the condition. SPSS 20.0 was adopted for statistical analysis. Results: The SF-36 survey showed that the mean score of body role before surgery (72.4±11.7) was significantly higher than that at 6 months after surgery (39.6±11.1, t=23.580, P<0.05) or that at 24 months after surgery (59.8±6.4, t=8.358, P<0.001). Compared with the preoperative mean scores of Physical Pain (73.0±11.0), General Health (73.4±10.4) and Health Changes (79.2±3.9) before surgery, the mean scores Physical Pain (53.1±7.7), General Health (53.5±7.5) and Health Changes (63.9±11.7) at 6 months after surgery were decreased significantly respectively (t=13.068, 13.756 and 10.880, respectively, all P<0.05), but the mean scores Physical Pain (78.8±14.0), General Health (80.9±12.6) and Health Changes (84.4±4.6) at 24 months after surgery were increased significantly respectively (t=-2.904, -4.027 and -7.586, respectively, all P<0.05), with significant differences in the mean scores of Physical Pain, General Health and Health Changes between 6 and 24 months after surgery (t=-14.241, -16.490, -14.294, respectively, all P<0.001). The UW-QOL survey showed that the mean scores of chewing, language and taste functions decreased at 6 months after surgery (53.1±6.7, 53.0±7.7 and 62.2±9.9, respectively), but improved at 24 months after surgery (67.9±3.9, 63.9±2.9 and 68.4±11.1, respectively), with statistically significant difference (t=-16.765, -11.675 and 2.498, respectively, all P<0.001). Conclusion: The application of folded fibula flaps to repair bone defects after sugery of mandibular ameloblastoma can better meet the needs of language and chewing functions and improve the quality of life of patients.
目的： 分析折叠腓骨瓣修复下颌骨成釉细胞瘤术后骨缺损患者的生命质量。 方法： 回顾性分析2013年8月至2016年4月郑州大学第一附属医院收治的39例下颌骨成釉细胞瘤患者的病例资料，其中男性21例，女性18例，年龄18~58岁。所有患者术前均经过3D打印和数字化技术进行准备，术中应用折叠腓骨瓣修复下颌骨缺损，并于术后6~9个月进行种植体植入术。应用简明健康状况调查问卷（short form-36 health survey questionnaire，SF-36）和华盛顿大学生存质量问卷（university of Washington quality of life questionnaire，UW-QOL）对患者术前、术后6个月、术后24个月的生命质量进行调查评估，分值越高表示状况越好。使用SPSS 20.0软件进行统计学分析。 结果： SF-36调查显示：躯体角色术前为（72.4±11.7）分，术后6个月［（39.6±11.1）分］下降（t=23.580，P<0.05），术后24个月［（59.8±6.4）分］仍无法恢复到术前水平（t=8.358，P<0.001）；术后6个月时躯体疼痛［（53.1±7.7）分］、总体健康［（53.5±7.5）分］、健康变化［（63.9±11.7）分］较术前［（73.0±11.0）分、（73.4±10.4）分和（79.2±3.9）分］下降（t=13.068、13.756、10.880，P值均<0.05），但术后24个月时的分值［（78.8±14.0）分、（80.9±12.6）分和（84.4±4.6）分］均高于术前（t=-2.904、-4.027、-7.586，P值均<0.05），且术后24个月与术后6个月相比差异有统计学意义（t值分别为-14.241、-16.490、-14.294，P值均<0.001）。UW-QOL调查显示：术后6个月下降的项目是咀嚼［（53.1±6.7）分］、语言［（53.0±7.7）分］和味觉［（62.2±9.9）分］，在术后24个月时改善［（67.9±3.9）分、（63.9±2.9）分和（68.4±11.1）分］，差异均有统计学意义（t值分别为-16.765、-11.675和2.498，P值均<0.001）。 结论： 采用折叠腓骨瓣修复下颌骨成釉细胞瘤术后的骨缺损，能够较好地满足语言和咀嚼功能的需求，提高患者的生命质量。.
