Outcome Measures

Primary Outcomes (1)

  • Histopathologic detection of any evidence of pilonidal sinus disease in the cavity excision material not dyed by methylene blue

    3 months

Study Arms (1)

Methylene Blue

EXPERIMENTAL

The effect of methylene blue dye in detection and total excision of pilonidal sinus will be studied histopathologically.

Procedure: Pilonidal sinus excision

Interventions

The dyed portion of the excised pilonidal sinus and non-dyed cavity excision specimen will be studied histopathologically to detect any remnant of pilonidal sinus.
