Background: Refractory pilonidal disease is a problem. We wished to show the utility of the cleft lift procedure in solving nonhealing.
Methods: We selected a subset of challenging cases for this study.
Hypothesis: Refractory pilonidal disease is due to damage of the epidermis in the deep gluteal cleft by moisture and bacteria, rather than to damage in deep tissues. A new paradigm suggests that a procedure to change the shape of the gluteal cleft will improve results.
Design: Before-and-after trial.
