Abdominal wall morphometric variability based on computed tomography: Influence of age, gender, and body mass index

Abstract : Introduction: Ventral hernia surgery does not usually account for the individuality of the abdominal wall anatomy. This could be both because medical imaging is rarely performed before surgery and because data on abdominal wall variability are limited. The objective of the present study was to perform an exhaustive morphometric analysis of abdominal wall components based on computed tomography (CT) scans. Materials and Methods: A retrospective study was performed on 120 abdominopelvic CT scans of clinically normal adults aged 18-86 y equally divided between women and men and into four age groups. Each abdominal wall muscle was evaluated in terms of area, thickness, shape ratio, fat infiltration, and aponeuroses width. The influence of age, sex, and BMI was investigated, as well as muscular asymmetry. Results: The abdominal wall muscle area represented 8.5±2.5% of the abdominal area. The internal oblique muscle had the largest area, the rectus abdominis was the thickest, the transversus abdominis was the narrowest and had the smallest area. The width of the linea alba was 20.3±12.0 mm. The evolution of the abdominal wall with age was quantified, as well as the large differences between the sexes and BMI groups, resulting in strong correlations and highlighting the specific pattern of the transversus abdominis. The asymmetry of the left and right muscle areas oscillated around 17%. Conclusions: The various components of the abdominal wall have been precisely described. Knowledge of their variability could be used to develop the numerical modeling of the abdominal wall to ultimately improve surgical planning of ventral hernia surgery.
