A review of 62 cases of blockage of head of malleus showed that apart from secondary lesions (post-traumatic, postoperative, postinfectious), primary blockades were a definite entity. The latter were either isolated or associated with stapedo-vestibular ankylosis. Isolated blockade of head of malleus provoties only direct transmission deafness, and is associated in nearly all cases with a cochlear lesion, often bilateral, at least in the primary forms. Instead of simple unblocking of the attic, the treatment preferred is an ablation of the incus, section of head of malleus and subsequent functional gestures that are described.
对62例锤骨头阻塞病例的回顾显示，除了继发性病变（创伤后、术后、感染后）外，原发性阻塞是一种明确的病症。后者要么是孤立的，要么与镫骨-前庭关节强硬相关。孤立的锤骨头阻塞仅导致传音性耳聋，且几乎在所有病例中都与耳蜗病变相关，通常为双侧性，至少在原发性形式中如此。治疗首选不是简单地疏通上鼓室，而是切除砧骨、切断锤骨头以及后续描述的功能性操作。
