The pathophysiology of so-called 'reparative granuloma' occurring after stapedectomy has not been determined and universally accepted management of this rare complication has not yet been established. A case is presented in which a mass developed in the middle ear after the use of a fat/wire prosthesis in a stapedectomy. Histological assessment revealed nonspecific granulation tissue and fat necrosis. It is suggested that 'reparative granuloma' is a misnomer as there is no microscopic evidence in this case nor in the literature of granulomatous formation. The condition may follow stapedectomy or stapedotomy. Furthermore, the name leads to confusion with a different condition, giant cell reparative granuloma, which involves the jaws and rarely the temporal bone. An alternative name, 'Stapes surgery induced granulation tissue' (SSIG) is therefore suggested for this condition.
镫骨切除术后出现的所谓“修复性肉芽肿”的病理生理学尚未明确，针对这种罕见并发症的普遍接受的治疗方法也尚未确立。本文报告了1例在镫骨切除术中使用脂肪/钢丝假体后中耳出现肿物的病例。组织学评估显示为非特异性肉芽组织和脂肪坏死。有人认为，“修复性肉芽肿”这一名称并不恰当，因为在该病例以及文献中均无肉芽肿形成的微观证据。这种情况可能发生在镫骨切除术后或镫骨足板造孔术后。此外，该名称会与另一种不同的疾病——巨细胞修复性肉芽肿相混淆，后者累及颌骨，很少累及颞骨。因此，建议将这种情况命名为“镫骨手术诱发的肉芽组织”（SSIG）。
