Brief Summary

The use of local liquid phenol for pilonidal sinus disease was first introduced by Maurica and Greenwood in 1964. Phenol, also known as carbolic acid, has been proven to be an effective sclerosing agent for treating pilonidal sinus diseas. Its antiseptic and anesthetic qualities make it suitable for application in awake patients under local anesthesia. The treatment of pilonidal sinus diseas in children with crystallized phenol was first published by Ateş et al in 2018. However, the treatment involving only crystallized phenol can require numerous sessions, potentially extending the duration of the treatment. IIn this study, the investigators, investigated whether the application of platelet-rich plasma following crystallized phenol treatment could accelerate the healing process and reach better outcomes. This study evaluates the efficacy of PRP as a treatment modality for pilonidal sinus disease in pediatric patients.

Outcome Measures

Primary Outcomes (6)

  • Average time to full daily activities

    It refers to the time when patients return to their routine lives after the procedure.

    1 week

  • VAS scores

    Patient visual analog scale (VAS) scores will be assessed both prior to the procedure and again 10 days following the procedure.

    2 weeks

  • Healing time

    It refers to the wound healing time of the patients after the procedure.

    7 weeks

  • Cosmetic score

    All patients will be assessed for cosmetic score after healing. For cosmetic evaluation, observers were asked to assess the scar in comparison to normal skin by answering the question, "What is your overall opinion of the scar compared to normal skin?" They rated the scar on a scale from 1 to 10, where 10 signifies normal skin and 1 represents a very different, worst possible scar.

    7 weeks

  • Success rate

    The succes rate will be calculated after interventions

    7 weeks

  • Recurrence rate

    The recurrence rate will be calculated after interventions

    7 weeks

Secondary Outcomes (4)

  • Bleeding rate

    1 week

  • Infection rate

    7 weeks

  • Skin burn rate

    7 weeks

  • Total complication rate

    7 weeks

Study Arms (2)

Crystallized phenol

ACTIVE COMPARATOR

Crystallized phenol group: The patients will undergo to crystallized phenol application.

Procedure: crystallized phenol

Crystallized phenol + platelet rich plasma

EXPERIMENTAL

Crystallized phenol + platelet rich plasma group. Alongside the crystallized phenol application + patients also will receive platelet rich plasma injections in the same session.

Procedure: crystallized phenol + platelet rich plasma application

Interventions

At our pilonidal care clinic, patients will undergo a comprehensive treatment regimen starting with manual or laser hair removal to reduce hair by over 90%. For pilonidal abscesses, we will perform incision, drainage, and antibiotic therapy. Treatments will include local anesthesia with lidocaine and epinephrine, thorough disinfection with povidone-iodine, and wound irrigation. Sinuses will be treated by removing hair and curettage, followed by protective ointment application and crystallized phenol to fill the cavity, ensuring precise dosing and safety. For enhanced healing, crystallized phenol + platelet-rich plasma application patients will receive platelet-rich plasma injections to minimize infection risk and promote tissue regeneration, all under strict sterilization to maintain cleanliness and efficacy.
