Abstract
Prosthetic hernioplasty is one of the most effective methods of incisional hernia repair. However, there is still a high risk of developing chronic pain syndrome associated with traumatization of the intercostal nerves during placement and fixation of the mesh in different body types. It is necessary to know the variant anatomy of the intercostal nerves depending on the constitutional characteristics of the patient.
The aim was to study the features of the topography intercostal nerves in the anterior abdominal wall with different body types.
Material and methods. The study involved 88 unfixed corpses of both sexes without pathology of the anterior abdominal wall. Were determined the number of intercostal nerves, the variant of their penetration into the rectus abdominis muscle, and the distance from the lateral edge of the rectus abdominis muscle to the point of penetration intercostal nerves into its thickness depending on the body type.
Results. In persons with a dolichomorphic body type there are 5 intercostal nerves most often (75%) and minimal indices of the distance from the lateral edge of the rectus abdominis muscle to the point of intercostal nerve penetration into its thickness (1.6±0.8 cm); in persons with a brachimorphic body type - 7 nerves (92.9%) and maximum indices of this distance (З.8±0.З cm). The posterior variant of the intercostal nerve penetration is more often found in patients with mesomorphic body type (88.9%), and the lateral variant - in patients with a brachymorphic type of constitution (80.7%).
Conclusion. It is necessary to take into account the variant anatomy of the intercostal nerves depending on the constitutional characteristics to reduce the risk of intraoperative traumatization of the intercostal nerves in prosthetic hernioplasty.
