Pilonidal Sinus Disease; What is the Best Treatment Option?

Introduction Sinus pilonidalis is a chronic infection of the hairy skin in the area of skin wrinkles, with the most common localization in the natal cleft. The disease often has a significant impact on the quality of life of the affected person; the treatment may be complex and needs to be adapted to the patient's needs. Methods Below is an overview of the origin as well as the treatment alternatives and their peculiarities. The following aspects are presented: early post-operative results, wound healing disorder and long-term results. Results The pathomechanism of pilonidal sinus disease has still not been conclusively clarified; it must continue to be assumed that the hair in the natal cleft contributes significantly to the formation. However, recent findings indicate that the large tufts of hair that are repeatedly found in the wound cavity are most likely to come from the hairy scalp. Three essential treatment options can be distinguished: The standard treatment of excision and subsequent open wound treatment, has a low recurrence rate, but requires considerable effort in wound treatment and thus leads to protracted time off work. Relatively new treatments include locally destructive treatment that essentially preserves the skin. Important representatives are so-called pit picking, fistuloscopy and other forms of treatment, such as phenol injection and/or laser treatment. In these treatment options, the final evaluation of the results is still pending. The third treatment group is excision and plastic reconstruction. These procedures are technically demanding, often involve inpatient treatment but lead to relatively good results in the long term. Conclusion Treatment of pilonidal disease requires patient-oriented therapy planning. The patient must be taught the different treatment options and a treatment recommendation must be given to the patient. Excision and open granulation continues to serve as a standard procedure with which other treatment options can be compared.
