This method has gained wide spread acceptance and is considered by many their first choice for difficult closure of midline abdominal wall defects. Edington et al. described that this innervated muscle complex can be advanced approximately 4 cm at the subxiphoid level, approximately 8 cm at the waist region, and 3 cm in the suprapubic region on each side, allowing the surgeon to reconstruct defects up to 16 cm in width at the waist level. Several modifications have been suggested to enhance the efficacy of abdominal wall component separation technique including: division of the external oblique muscle, separation of external oblique muscle from internal oblique muscle, division of internal oblique muscle, separation of rectus abdominis from posterior rectus sheath, periumbilical perforator preservation, bilateral transverse subcostal incisions ,endoscopically assisted component separation and recently Memphis Modification.
