After transsphenoidal resection of a pituitary (or other) tumor, the remaining intrasellar cavity, and sphenoid sinus are usually packed with exogenous fat or muscle to prevent cerebrospinal leak and prolapse of the optic chiasm into an empty sella. We treated two patients in whom chiasmal compression occurred postoperatively because of packing of fat. In one patient, the expected visual improvement in the postoperative period was suboptimal. The subsequent removal of fat resulted in total visual recovery. In the other patient, chiasmal compression persisted from intrasellar fat and residual tumor. Iatrogenic compression of the optic nerves or chiasm should be considered in all patients in whom visual recovery is incomplete.
在经蝶窦切除垂体（或其他）肿瘤后，通常会用外源性脂肪或肌肉填充剩余的蝶鞍内腔和蝶窦，以防止脑脊液漏和视交叉脱垂至空蝶鞍。我们治疗了两名因脂肪填充而术后发生视交叉受压的患者。其中一名患者，术后预期的视力改善未达最佳。随后去除脂肪后视力完全恢复。另一名患者，视交叉受压因蝶鞍内脂肪和残留肿瘤持续存在。对于所有视力恢复不完全的患者，都应考虑医源性视神经或视交叉受压的情况。
