The use of nonabsorbable prosthetic materials such as polypropylene, polyester, and ePTFE, have expanded and are now widely used in reparative surgery for abdominal wall hernias.

A review of the history of inguinal hernia repair from the far surgical approach performed by Celso, trought the physiological reconstruction of inguinal canal by Bassini and the introduction of the concept of tensionfree repair, to the newest find in this specialist surgery. Nowadays in addition to the choice of approach (open vs laparoscopic, anterior vs preperitoneal), the plane where placing the mesh (in front of the trasversalis fascia vs preperitoneal space), and the fixation device (suture vs sutureless vs glue), surgeons can select among a wide range of prosthesis. Choosing the proper biomaterial can determine the success of an operation and prevent biomaterial-related complications. Indepth knowledge and understanding of the physical properties of the prosthesis, porosity, and pore size in particular are required. Modern advances in hernia repair are credited with reduced recurrence rate, so surgeons' attention is shifted from preventing recurrence to the new topic of chronic pain after surgery.
