Type of Incisions: McBurney
The Rocky-Davis incision provides another option.
Unlike the McBurney incision, it is a straight transverse at
the skin and splits the muscle. Again, either incision is
made as long as necessary to achieve adequate exposure. Thin
people require a smaller incision than obese patients. Those
patients with an anterior appendix are usually easier to
manage through a small incision, as opposed to retrocecal
appendices which require an extended incision.
Extending the right lower quadrant incision for
greater exposure usually requires either medial extension
opening the rectus fascia and displacing the rectus muscle
medially, or a second midline incision. The second midline
incision may be considered in patients with pathology that
extends beyond the right lower quadrant.
