The objective of this study was to evaluate the variation of the orbital volume and the correlation with the magnitude of craniofacial advances as well as demonstrate its effectiveness through comparisons with normal levels of orbital volumes.
Syndromic craniofacial synostosis is characterized by cranial morphological alterations and hypoplasia of the midface that may result in obstructive sleep apnea and exorbitism; these effects are indications of surgical treatment. The gradual advancement of tissues is the surgical treatment to correct accentuated exorbitisms and jaw retrusions.
This was a retrospective study by review of medical records and tomographic examinations of 20 patients submitted to distraction osteogenesis between 2001 and 2012, who were divided into 2 groups: groups MB and LF with 11 and 9 patients, who underwent frontofacial or Le Fort III osteotomy. The orbit volume was measured with the InVesalius and Magics software, and facial advancements with Rhinoceros software. Statistical analyses were conducted using Student t test and analysis of variance.
Patients' ages ranged from 6 to 29 years. Group MB showed an increase of 8.94 and 9.84 mm(3) in the right and left orbit volume variation, whereas group LF presented 5.70 and 5.77 mm(3). The average advancements in the right and left orbits were 11.36 ± 3.80 and 11.11 ± 3.45 mm in group LF, respectively, and 14.22 ± 4.12 and 14.48 ± 4.49 mm in group MB.
Exorbitism was satisfactorily treated. The correlation was proportional in group LF and group MB. There was normalization of orbital volume compared with normal levels of orbital volumes.
本研究的目的是评估眼眶容积的变化及其与颅面进展幅度的相关性，并通过与正常眼眶容积水平进行比较来证明其有效性。
综合征性颅面骨缝早闭的特征是颅骨形态改变和中面部发育不全，这可能导致阻塞性睡眠呼吸暂停和眼球突出；这些影响是手术治疗的指征。组织的逐步推进是纠正严重眼球突出和颌骨后缩的手术治疗方法。
这是一项回顾性研究，通过查阅2001年至2012年间接受牵张成骨治疗的20例患者的病历和断层扫描检查进行，这些患者分为两组：MB组和LF组，分别有11例和9例患者，他们接受了面中部或Le Fort III截骨术。使用InVesalius和Magics软件测量眼眶容积，使用Rhinoceros软件测量面部进展。采用学生t检验和方差分析进行统计分析。
患者年龄在6至29岁之间。MB组右眼眶容积变化增加了8.94和9.84立方毫米，左眼眶容积变化增加了5.70和5.77立方毫米。LF组右眼眶和左眼眶的平均进展分别为11.36±3.80毫米和11.11±3.45毫米，MB组分别为14.22±4.12毫米和14.48±4.49毫米。
眼球突出得到了满意的治疗。LF组和MB组的相关性是成比例的。与正常眼眶容积水平相比，眼眶容积实现了正常化。
