摘　　要：目的探讨羟基磷灰石微粒人工骨修复额部皮样囊肿切除后骨骼凹陷畸形的疗效及并发症。方法2000年2月~2005年5月,采用羟基磷灰石微粒人工骨修复13例额部皮样囊肿切除后的额骨凹陷畸形患者。男9例,女4例,年龄17~41岁。囊肿均在婴、幼儿期出现,囊肿大小6cm×4cm^10cm×8cm。设计发际缘或囊肿周缘的切口,完整切除皮样囊肿,并去除额骨凹陷处表面的骨膜等软组织后,以适量的羟基磷灰石微粒人工骨充填修复额骨凹陷。于术后1周,1、6个月进行临床和X线片检查。结果术后患者切口均期愈合,无血肿、血清肿、感染及羟基磷灰石颗粒人工骨移位等并发症发生。均获随访1~20个月,额骨凹陷完全修复,局部皮肤平滑,外观无明显凹陷;局部检查和X线片示,植入的羟基磷灰石颗粒人工骨与周围骨质结合紧密,无明显缝隙,人工骨未见移位。结论羟基磷灰石微粒人工骨充填修复皮样囊肿切除后的额骨凹陷是一种简单易行和较理想的方法。Objective To investigate aesthetic outcomes and postoperative complications of hydroxyapatite particulate artificial bone for repairing sunken deformation of frontal bone following removal of dermoid cyst. Methods From February 2000 to May 2005, hydroxyapatite particulate artificial bone was used to repair the sunken deformation of frontal bone in 13 cases （9 males and 4 females）, and the age of the patients was from 17 to 41 years. The dermoid cysts were all found during infant period, and the length and width of the cysts ranged from 6 cm × 4 cm to 10 cm× 8 cm. An incision along the hair-edge or tumor margin was made to excise the dermoid cyst in the forehead. After complete removal of dermoid cyst, the sunken frontal bone was examined and repaired with hydroxyapatite particulate artificial bone. The clinical check-up and X-ray examination were utilized to determine aesthetic outcomes and postoperative complications at 1 week, 1 month and 6 months after operation. Results The primary wound healing was ohtained in all patients postoperatively, and no complications such as hematoma, infection, recurrence of dermoid cysts or displacement of hydroxyapatite particulate artificial bone were observed. With a follow-up from 1 to 20 months, all sunken deformations were completely repaired with satisfactorily aesthetic outcomes. Through clinical check-up and X- ray examination, the implants were found to integrate with the frontal bones without any gaps and displacement. Conclusion It is a simple and viable method to repair sunken deformation of frontal bone with hydroxyapatite particulate artificial bone.
