The liver fossa, more accurately known as the fossa for the gallbladder (fossa vesicae felleae), is a shallow, oblong depression located on the under surface of the right lobe of the liver. It runs parallel with the left sagittal fossa.
Details of the Liver Fossa
- Location: Found on the inferior (under) surface of the right lobe of the liver.
- Shape: Described as a shallow, oblong depression.
- Orientation: Runs parallel to the left sagittal fossa, another important landmark on the liver's inferior surface.
- Boundaries: It extends from the anterior free margin of the liver (where a notch is present due to the fossa) to the right extremity of the porta hepatis (hilum of the liver).
- Content: It lodges the gallbladder.
Function
The primary function of the liver fossa is to provide a bed or lodging for the gallbladder. The gallbladder sits within this depression, attached to the liver.
Clinical Significance
Understanding the location of the liver fossa is crucial for surgeons during procedures involving the liver and gallbladder, such as cholecystectomies (gallbladder removal). Its proximity to other important structures within the liver, such as the porta hepatis, requires careful attention to avoid complications.
