Craniofacial clefts are rare malformations. According to their localization, 15 types are classified.
They referred to impaired eyelid function, lateral protection of the eye-bulb, and aesthetic appearance.
A three-dimensional-computerized tomography scan and a stereolithographic model led to the diagnosis of a rare intraorbital Tessier 6 cleft.
A newly designed lateral orbital rim osteotomy, presurgically simulated on a stereolithographic model, was performed to forward position the lateral orbital rims bilaterally by osteodistraction.
Both lateral orbital rims were distracted anteriorly for around 12 mm over a period of 9 weeks, without any side effects to the patient.
TAKE-AWAY LESSONS: In this intraorbital Tessier 6 cleft, an improved eyelid function with better lateral protection of the eye bulb and more favorable aesthetic appearance was achieved with this novel lateral orbital rim osteotomy.
颅面裂是罕见的畸形。根据其位置,可分为15种类型。
患者提到眼睑功能受损、眼球的外侧保护以及美观问题。
三维计算机断层扫描和立体光刻模型诊断为罕见的眶内Tessier 6型裂。
在立体光刻模型上进行术前模拟的新设计的外侧眶缘截骨术,通过骨牵引双侧向前移位外侧眶缘。
在9周的时间里,双侧外侧眶缘均向前牵引约12毫米,对患者无任何副作用。
在这种眶内Tessier 6型裂中,这种新型外侧眶缘截骨术改善了眼睑功能,更好地保护了眼球外侧,并且外观更美观。
