Inverted '?' technique without loss of skin tissue compared to classical open surgery technique in pediatric pilonidal sinus disease

Aim: Although the pilonidal sinus disease is commonly treated with surgical methods, search for optimal surgical procedures and minimally invasive methods continues. The aim of this study was to evaluate the inverted '?' technique which provides a tension-free closure with minimal tissue loss, by comparing with the classical open surgery technique. Material and Methods: Sixty-five patients, 37 (56.9%) male and 28 (43.1%) female, with a mean age of 15.85±1.82 years, admitted between January 2014 and October 2020 and underwent inverted '?' surgery and classical midline open surgery were retrospectively evaluated. Results: As an early postoperative complication, bleeding was observed in 2 (7.4%) patients in inverted '?' group and 3 (11.1%) patients had wound infection. The same complications were 4 (10.5%) and 4 (10.5%) in classical group, respectively. The time to return to full activities was statistically different between two groups (10.36±0.43 versus 11.30±0.93 days, p
