Implantation of a gold weight in the pretarsal space was performed on 17 patients with poor eyelid closure secondary to facial nerve weakness. Successful results were obtained in 14 (82%) of 17 patients. Postmortem histopathology of such a case demonstrated firm fibrous encapsulation of the weight. Although some authors advocate fixation of lid weights to the orbital septum, fixation in the pretarsal space is preferred for the following reasons: (a) "cheesewiring" is less likely to occur, (b) a limited levator recession may be more easily performed, (c) greater mechanical benefits are obtained, and (d) the potential for inferior migration is less.
对17例因面神经麻痹导致眼睑闭合不良的患者在睑前间隙植入金质重物。17例患者中有14例（82%）获得了成功的结果。该病例的尸检组织病理学显示重物被牢固的纤维组织包裹。尽管一些作者主张将眼睑重物固定于眶隔，但由于以下原因，睑前间隙固定更佳：（a）较少可能发生“奶酪线样变”；（b）更易于进行有限的提上睑肌后退；（c）可获得更大的机械效益；（d）向下移位的可能性较小。
