Anterior versus posterior component separationfor hernia repair in a cadaveric mode

Component separation via both anterior and posterior approaches provide substantial myofascial advancement.In our model, we noted statistically greater anterior fascial medialization after PCS versus ACS as a whole, and especiallyin the upper and mid-abdomen. We advocate PCS as a reliable and possibly superior alternative for linea alba restoration forreconstructive repairs, especially for large defects in the upper and mid-abdomen.


“Component separation during hernia repair has proven a useful tool in the armamentarium of the general surgeon allowing for the repair of larger and more complex hernia defects. Although there are many techniques described, the ability to obtain myofascial medialization, thus allowing restoration of linea alba, remains the cornerstone of component separation techniques. Both anterior and posterior approaches have proven clinical track records and are valuable tools for reconstructive surgeons”
