Abstract

   The study of morphometric parameters of the thoracic diaphragm in diverse body constructions is of applied relevance in thoracic and abdominal surgery.   The aim of the study was to investigate regional morphometric parameters of the thoracic diaphragm in diverse body constructions.   Material and methods. The study involved 40 specially embalmed corpses (with preserved tissue elasticity), aged 35-75 when dying. To assess the morphometric parameters of the diaphragm, there was tailor-made an organocomplex represented by the abdominal cavity covered by an intact diaphragm. Longitudinal, transverse dimensions, the area of the diaphragm and its parts were investigated.   Results. The analysed morphometric features allowed specifying that in extreme body constructions, there were considerable statistically significant differences in the morphometric parameters of the diaphragm and its parts. It was established that the largest area of the diaphragm, central tendon, costal part and its pericardial surface were observed in people with a brachymorphic body construction; the highest statistical significance was observed between extreme body constructions. The ratio of the tendon part to the total area was also the largest in the brachymorphic form, and the smallest in the dolichomorphic form. There were specific morphometric parameters typical of all types of body constructions: the ratio of the muscular and tendon parts of the diaphragm, the depth of the pleural sinuses, and the areas of the weak points of the diaphragm. The largest linear dimensions of all parts of the diaphragm were recorded in individuals with a brachymorphic body construction. On the contrary, people with dolichomorphic body type had the lowest values. However, the diaphragm domes were the highest in individuals with a dolichomorphic form, and the shortest in those with a brachymorphic form.   Conclusion. The study of the morphometric parameters of the thoracic diaphragm allowed recording the major linear dimensions and areas of definite parts specific for all body constructions. The results obtained can be introduced into clinical practice to plan surgical interventions on the upper floor of the peritoneal cavity, including diaphragmatic peritonectomy.
不同体型胸椎横膈膜的形态测量参数
研究不同体型胸膈的形态参数在胸腹外科手术中具有重要的应用价值。本研究的目的是研究不同体型胸椎横膈膜的区域形态学参数。材料和方法。这项研究涉及40具经过特殊防腐处理的尸体(保存了组织弹性),年龄在35-75岁之间。为了评估横膈膜的形态参数,我们制作了一个由完整横膈膜覆盖的腹腔代表的器官复合体。研究了膜片的纵向、横向尺寸以及膜片及其部件的面积。结果。分析的形态特征允许指定在极端的身体结构中,在隔膜及其部件的形态参数上有相当大的统计学显著差异。结果表明:短形体构造者的横膈膜、中央腱、肋部及其心包表面面积最大;在极端身体结构之间观察到最高的统计显著性。肌腱部分占总面积的比例在短形形态中最大,在多形形态中最小。所有类型的身体构造都有特定的形态测量参数:横膈膜肌肉和肌腱部分的比例,胸膜窦的深度,以及横膈膜薄弱的区域。横膈膜所有部分的最大线性尺寸记录在具有短形身体结构的个体中。与之相反,多相体型的人的值最低。然而,膜片穹丘在多形型个体中最高,在短形型个体中最短。结论。通过研究胸膈的形态参数,可以记录所有身体结构特定部位的主要线性尺寸和面积。所获得的结果可用于临床实践,以规划腹膜上层的手术干预,包括膈腹膜切除术。
