A New Surgical Technique for Closure of Pilonidal Sinus Defects: Triangular Closure Technique

Area of Science:

• Plastic Surgery
• Surgical Techniques
• Wound Reconstruction

Background:

• Pilonidal sinus disease often results in sacrococcygeal skin defects.
• Traditional reconstruction methods may have limitations.
• A novel local flap procedure, the triangular closure technique, is introduced.

Purpose of the Study:

• To evaluate the clinical experience and outcomes of the triangular closure technique for sacrococcygeal defects.
• To assess the efficacy and safety of this technique in pilonidal sinus disease management.

Main Methods:

• The triangular closure technique involves converting the defect to a triangle and closing it with unequal z-plasty skin flaps.
• The technique was applied to 27 patients with chronic pilonidal sinus disease over six years.
• Defect sizes ranged from 3.5 cm to 12 cm.

Main Results:

• All patients achieved tension-free defect closure.
• Flap healing was successful in all but one patient, with no major complications.
• Follow-up revealed aesthetically and functionally acceptable results, including natal cleft obliteration.
• No recurrence of pilonidal sinus disease was observed.

Conclusions:

• The triangular closure technique is a viable and effective method for treating pilonidal sinus.
• The procedure yields favorable aesthetic and functional outcomes.
• This technique may reduce the time to return to work for patients.
