Triangular excision with an advancement flap is an effective yet underreported technique for pilonidal sinus disease with unilateral superolateral secondary pits, where minimally invasive methods often fail. The inverted triangular design allows complete excision of the sinus cavity and pits, and the defect is closed with a tension-free advancement flap, ensuring rapid recovery. Applicable to disease of varying vertical extent within or beyond the navicular area, this approach preserves healthy tissue and provides a practical alternative to conventional flap procedures.
