48 temporal bones, fixed in 10 percent formaline, were dissected by microdissection and the anterior malleus ligament was studied morphological and histologically. Some gross sections were made to microscopic observations and microssections, to histologic preparations. The anterior malleus ligament shows fasciculate aspect in its intratympanic portion, by 3 fascicles , superior, middle and inferior, with dentate form. The superior fascicle is whitish, dimmed and frequently thinner than the others and was classified under 4 patterns, according to its insertion. The middle fascicle is the thickest, voluminous+, whitish and shinning ; tendinous, it is inserted below the superior fascicle . The inferior fascicle is thickness and insert immediately under the middle one. The extratympanic portion of the anterior malleus ligament is fasciculate but little evident; it shows irregular aspect, flattened, with disperses fibres into the petrotympanic fissure. However can be noted continuity of the fascicles that are crossed by the nerve chorda tympani. Several fibres insert on the nasal spine and on the sphenomandibular ligament, where the fibres intertwine. They finish on the disc, articular capsule and anterior malleus ligament through a true interlinked. Histological observations of the anterior malleus ligament show a modelate and dense conjunctive formation, while in the temporomandibular joint capsular region was not a modelate conjunctive.
对48块固定于10%甲醛中的颞骨进行显微解剖，研究锤骨前韧带的形态学和组织学特征。制作了一些大体切片用于显微镜观察，并制作了显微切片用于组织学制备。锤骨前韧带在鼓室内部分呈束状，由上、中、下3束组成，呈齿状。上束呈白色，色泽暗淡，通常比其他束薄，根据其附着情况可分为4种类型。中束最厚，体积较大，呈白色且有光泽；呈腱性，附着于上束下方。下束较厚，紧附于中束下方。锤骨前韧带的鼓室外部分呈束状，但不太明显；呈不规则形，扁平，纤维分散于岩鼓裂。然而，可以注意到鼓索神经穿过的束的连续性。一些纤维附着于鼻棘和蝶下颌韧带，纤维在那里相互交织。它们通过真正的连接终止于椎间盘、关节囊和锤骨前韧带。锤骨前韧带的组织学观察显示为中等程度且致密的结缔组织形成，而颞下颌关节囊区域则不是中等程度的结缔组织。
