After enucleation, a spherical implant of some material is placed into the muscle cone to give bulk to the orbital socket area. This also allows better movement of the artificial eye prosthesis, which is placed in the socket to give the appearance of a normal eye. If there is loss of the spherical implant because of infection or extrusion for other reasons, there is a resulting enophthalmos of the prosthetic eye. Replacement of this spherical implant with another implant of alloplastic material often results in secondary extrusion. In other cases, there is downward displacement of the spherical implant with pressure against the prosthesis and lower lid. This causes undue stretching of the lower fornix and lid area with inability to hold the prosthesis in place. To correct these two problems, we have found that an autogenous cartilage graft is useful for an implant that will not extrude and that holds its position. Examples of this technique and preoperative and postoperative cases are described here. We have used this technique over the past 11 years and have achieved good success in 15 patients.
眼球摘除术后，将某种材料制成的球形植入物放入肌锥内，以使眼眶区域丰满。这也能使放置在眼窝中的人工眼球假体更好地活动，从而呈现出正常眼睛的外观。如果由于感染或其他原因导致球形植入物丢失，义眼就会出现眼球内陷。用另一种异体材料植入物替换这个球形植入物往往会导致二次挤出。在其他情况下，球形植入物会向下移位，压迫假体和下眼睑。这会导致下穹窿和眼睑区域过度伸展，无法固定假体。为了纠正这两个问题，我们发现自体软骨移植对于不会挤出且能保持其位置的植入物很有用。本文描述了该技术的实例以及术前和术后病例。在过去11年中我们使用了这种技术，15例患者取得了良好效果。
