AbstractIn spite of a number of ingenious operative and non-operative techniques in the management of pilonidal sinus no single technique can be relied upon to prevent recurrence of this benign yet troublesome condition. Once thought to be a congenital condition it is now appreciated that pilonidal sinus most often an acquired condition due to accumulation of tough, bristly hair penetrating the skin, or local hair growing into a skin crevice, pit or abnormal follicle. The most common site is the upper natal cleft but the condition may occur in other sites especially where there is a crevice or irregularity of skin surface with pressure or suction applied to that region. Most surgical procedures have been designed to eradicate the existing sinus and the crevice in which hair tends to accumulate. However, without the presence of hair there can be no pilonidal sinus and, in the past, little attention has been given to preventing the re-accumulation of hair in the troublesome site; hence the risk of recurrence. Management objectives should be directed not only at eradicating the obvious lesion present but also to preventing recurrence of aetiological factors; especially the re-accumulation or re-growth of hair.
