To evaluate the development of orbital volume in five adults who underwent enucleation without orbital implant during early childhood, using reconstructed computed tomography(CT) images.
The orbital volume of 5 adults who underwent enucleation without orbital implants during early childhood was measured using CT images, and the results were compared between the anophthalmic orbit and the unaffected orbit in each case. The shape of maldevelopmental orbit and the relationship between orbital development and replacement of the prosthesis were also investigated.
Orbital development in patients who underwent enucleation without orbital implant during early childhood was delayed in comparison with the unaffected orbit, and the delayed development was especially remarkable at the part of orbit corresponding to the equator of the eyeball. Maldevelopment of the orbit was severer in cases without replacement of the prosthesis than with it.
For the development of orbital volume in anophthalmos after enucleation, orbital volume in place of the eyeball is required. Therefore, orbital implantation at the time of enucleation and replacement of the prosthesis with larger ones as the body grows are important.
利用重建的计算机断层扫描(CT)图像,评估5名在幼儿期接受眼球摘除术且未植入眼眶植入物的成年人眼眶容积的发育情况。
使用CT图像测量5名在幼儿期接受眼球摘除术且未植入眼眶植入物的成年人的眼眶容积,并将每例无眼球眼眶与未受影响眼眶的结果进行比较。还研究了发育不良眼眶的形状以及眼眶发育与假体置换之间的关系。
与未受影响的眼眶相比,在幼儿期接受眼球摘除术且未植入眼眶植入物的患者眼眶发育延迟,且在与眼球赤道相对应的眼眶部分,发育延迟尤为明显。未进行假体置换的病例眼眶发育不良比进行假体置换的病例更严重。
对于眼球摘除术后无眼球眼眶容积的发育,需要用眼眶容积来替代眼球。因此,眼球摘除时进行眼眶植入以及随着身体生长用更大的假体进行置换很重要。
