Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Pilonidal sinus disease (PNS) has an incidence of approximately 26 per 100,000 population with a male predominance of 2:1 and the mean age of those affected is from 19 to 30 years of age. It occurs rarely after the age of 45 and children.
Pilonidal sinus disease is characterized by natal cleft suppuration due to hair follicle infection. The disease results from chronic infection of hair follicles and subsequent formation of a subcutaneous abscess because of persistent folliculitis. Hair then enters the abscess cavity and provokes a foreign body tissue reaction; chronic suppuration and discharge through a midline sinus follow.
Some individuals are asymptomatic with midline pits in the sacrococcygeal area, Symptomatic Pilonidal sinus results in chronic discharging wounds that cause pain and impact upon quality of life and social function. These sinuses may become infected and present as acute abscesses. Management of these abscesses is uncontroversial and revolves around incision and drainage, however, the mode of surgical management of the chronic discharging sinus is variable, contentious, and problematic.
The Principles of Surgical strategies require eradication of the sinus tract, complete healing of the overlying skin, and prevention of recurrence. Many methods are available for surgical management of PNS which is treated by wide excision. After excision, the wound may be left open to heal with granulation tissue, or may be immediate closed with a midline closure or by using a flap (Z-plasty, karydakis, Bascom or Rhomboid flaps). However, there is not yet a consensus on the optimal treatment.
Excision and healing by granulation is still preferred due to the low recurrence rate of (3.4%) compering with other methods (20.6%) for midline closure and (10.3%) for off-midline closure but the healing time is lengthy and requires a prolonged time of daily dressing with a risk of infection and delayed wound healing. Therefore, the search for a treatment with minimal pain, accelerated healing time and a short span of time for returning to the normal daily activities is vastly pursued.
A recent method to promote the wound-healing process is the local administration of an autologous platelet concentrate suspended in plasma named as platelet rich plasma (PRP) which contains growth factors. Concentrated growth factors have been reported to accelerate wound healing by 30-40% giving a satisfactory outcome in the treatment of chronic skin and soft tissue lesions, maxillofacial and plastic surgeries by presenting these high amounts of growth factors and chemokines.
When platelets become activated, Seven fundamental protein growth factors that are actively secreted by platelet initiate all wound healing process, including platelet derived growth factor (PDGF), epidermal growth factor (EGF), transforming growth factor (TGF), vascular endothelial growth factor (VEGF), Fibroblast growth factor (FGF), connective tissue growth factor (CTGF) \& insulin like growth factor (ILGF 1) all participate in the acceleration of wound-healing process.

Group A
50 Participants who underwent a total excision of the pilonidal sinus and the wound remained open for secondary healing.
No interventions assigned to this group
Group B
50 Participants who underwent the same operation with secondary healing intention but on postoperative days 4 and 12 the platelet rich plasma was injected to the surgical wound.
Platelet Rich Plasma
Autologous PRP obtained via double centrifugation process of the participant's blood sample. PRP was prepared by the double Spain strategy.
