Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The aim of this study is to compare a new method (GMFF) with a traditional method (midline excision and primary closure) in terms of recurrence rate, complications and patient satisfaction with results.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Traditional surgical techniques encompass midline excision of the purulent cyst and either leaving the wound "lay open" for secondary closure or midline primary closure. The latter method has a major drawback of high recurrence rate and very long healing and patient disability periods. Therefore alternative techniques to close the wound after pilonidal sinus excision were proposed. In some a muscular-cutaneous flaps are created and the wound is closed in a Z- or Y- or other shape manner. The recurrence rate of these techniques is significantly lower than with a traditional midline closure, but healing time and final cosmetic results are far from ideal in patient view.
Recently a new method of wound closure was developed independently by a few groups that includes bilateral mobilisation of gluteus maximus muscles fascia and midline closure of the wound. Preliminary results demonstrated that this method leads to lower recurrence rate and better cosmetic results because the natal cleft is saved.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Primary Closure
After pilonidal sinus is excised, subcutaneous fat and skin are closed in midline with a running suture
Primary Closure
A symmetrical elliptical incision of skin and subcutaneous fat around primary and secondary orifices is performed. The cyst is excised en bloc down to the sacral fascia and removed. The lateral edges of the wound are approximated and sutured in the midline: subcutaneous fat - with a running suture, skin - with a separate running suture.
Gluteus Maximus Plasty Flap
After pilonidal sinus is excised, gluteus maximus fascia flaps will be mobilised, approximated in the midline and fixed with a running suture. Subcutaneous fat and skin are closed in midline with a running suture.
Gluteus Maximus Fascia Plasty Flap
A symmetrical elliptical incision of skin and subcutaneous fat around primary and secondary orifices is performed. The cyst is excised en bloc down to the sacral fascia and removed. The lateral edges of the gluteus maximus muscles fascia bilaterally are mobilised in the direction from the fixation point to the sacrum and for 3-4 cm in lateral direction. The fascia flaps edges are approximated and fixed in the midline with a running suture. The subcutaneous fat is closed with a running suture, skin is closed with a separate running suture.
