Primary Closure Techniques in Chronic Pilonidal Sinus

Abstract

Beside the various statistical considerations when using a pooled data analysis combining results from the literature, this overview suggests a significant benefit of asymmetric-oblique closure techniques or flap techniques in comparison with simple closure in the midline. Thus, we recommend an asymmetric closure technique for primary closure of a chronic pilonidal sinus. These asymmetric procedures provide better results than the simple closure in the natal midline. Furthermore, they are not as sophisticated as the full-thickness plasty techniques.
