What incision is also known as a lower oblique?

1. Inguinal

2. Paramedian

3. Infraumbilical

4. Thoracoabdominal

The correct answer is: Inguinal

The incision referred to as a lower oblique is the inguinal incision. This type of incision is specifically designed to access the inguinal region, typically used for procedures such as hernia repairs. The lower oblique feature allows for a better cosmetic result and helps to minimize damage to the underlying structures, such as nerves and blood vessels. Inguinal incisions are made in a direction that is parallel to the natural lines of the body, which contributes to healing and reduces the visibility of the scar. The approach that this incision provides is particularly beneficial when addressing conditions in the groin area due to its proximity to critical anatomical structures. The other options represent different types of incisions that serve specific purposes but do not align with the term "lower oblique." For example, a paramedian incision is made alongside the midline of the abdomen but does not have the same angle or cosmetic considerations as an inguinal incision. The infraumbilical incision is used below the umbilicus and is typically a vertical incision. Meanwhile, the thoracoabdominal incision extends from the thorax into the abdomen but does not have an oblique orientation. Each of these incisions is chosen based on the surgical requirements and the area being accessed, but
