INTRODUCTION: Pilonidal Sinus was first described by Hodges in 1880.It is one of the common problems encountered in general surgical practice. The management of this disease is variable, contentious and problematic . Principles of treatment include eradication of sinus tract, complete healing and prevention of recurrence. Although several surgical techniques are described over the years, its management still remains controversial. AIMS AND OBJECTIVES: The aim of this study is to compare the two techniques – Open method and Z– Plasty in management of pilonidal sinus in terms of healing time, rate of surgical site infection, time before return to work, morbidity, recurrence, cost and determine the most appropriate technique for the management of chronic pilonidal sinus disease. MATERIALS AND METHODS: This is a prospective study which was conducted in the surgical department of Sree Balaji Medical College and Hospital over a period of 2 years(August 2017–July 2019).A total of 30 cases were included in this study.Of these,23 cases were operated by Z–plasty and 7 cases by the Open technique. OBSERVATION AND RESULTS : In our study, maximum patients were in third decade of life and male to female ratio was 4:1. Mean hospital stay and total recovery time was significantly higher in open technique group as compared to Z–plasty group Mean post operative pain score was more in open group. Recurrence was found in open technique and there was no recurrence in Z–Plasty group. CONCLUSION: Excision with Z–Plasty is a better technique as it has lesser total recovery time, lesser hospital stay, less post–operative pain, lesser recurrence and better quality of scar
