The upper part of the lateral nasal wall is formed by a common structure or conchal lamina that is attached all along the junction between the ethmoidal roof and the cribriform plate. From this continuous conchal lamina, the different ethmoidal turbinates take their origin. All these structures form a well defined wall that encloses the ethmoidal cells medially and that deserves the name of "turbinal wall of the ethmoidal labyrinth". The objectives of this paper were: 1) to precisely define the anatomical landmarks of the turbinal wall of the ethmoidal labyrinth, and 2) to study, from an anatomical point of view, the consequences of the surgical resection of the middle turbinate. We performed an anatomic study on 12 frozen human heads, cut in a median-sagittal plane, and then photographed with a millimetre scale in order to perform several measurements. The surface of the turbinal wall of the ethmoidal labyrinth can range from 6.1 to 11.3 cm2. The resection of the middle turbinate preserves approximately half of the turbinal wall, this being around 4.3 cm2 (range 2.6 to 6.3 cm2). The conchal lamina appears as the noble sensorial element of the turbinal wall. It can be described as a continuous bone plate, grossly rectangular in shape, measuring approximately 1 cm in height and 3.5 cm in length that forms the lateral wall of the olfactory groove. The anatomic study shows that its dimensions can vary from simple to double in different individuals. It seems to us that instead of considering the difference of height between the cribriform plate and the ethmoidal roof (Keros classification), we should consider the vertical height of the conchal lamina as a potential risk factor in ethmoidal surgery.
鼻外侧壁的上部由一个共同的结构或鼻甲薄板构成，该结构沿筛骨顶与筛板之间的连接处全程附着。不同的筛鼻甲均起源于这个连续的鼻甲薄板。所有这些结构形成了一个界限分明的壁，在其内侧包绕着筛窦气房，因而值得被称为“筛迷路鼻甲壁”。本文的目的是：1）精确界定筛迷路鼻甲壁的解剖学标志；2）从解剖学角度研究中鼻甲手术切除的后果。我们对12个经正中矢状面切开的冷冻人头进行了解剖学研究，然后用毫米尺拍照以便进行多项测量。筛迷路鼻甲壁的表面积在6.1至11.3平方厘米之间。中鼻甲切除术后保留了大约一半的鼻甲壁，约为4.3平方厘米（范围为2.6至6.3平方厘米）。鼻甲薄板似乎是鼻甲壁的重要感觉元件。它可被描述为一块连续的骨板，大致呈矩形，高约1厘米，长约3.5厘米，构成嗅沟的外侧壁。解剖学研究表明，其尺寸在不同个体中可从单倍变化为双倍。在我们看来，在筛窦手术中，与其考虑筛板与筛骨顶之间的高度差异（凯罗斯分类法），不如将鼻甲薄板的垂直高度视为一个潜在的风险因素。
