Background: A pilonidal sinus (PNS) is a small cyst or abscess that occurs in the cleft at the top of the buttocks. A PNS usually contains hair, dirt, and debris. It can cause severe pain and can often become infected. If it becomes infected, it may ooze pus and blood and have a foul odor. The exact cause of pilonidal sinuses is unclear. It is generally thought they are caused by loose hairs pushing into the skin. They could also be caused by deep layers of skin being stretched and moved, leading to a hair follicle rupturing. Aim of the Work: The prospective study aimed at evaluating the outcomes of management of recurrent pilonidal sinuses by rhomboid flap. Patients and Methods: A prospective study of cases with recurrent pilonidal sinus, was done at the department of general surgery at In Al-Azhar University hospitals over the period from July 2017 with medium follow up period of three months. Results: Age: ranged between 17 to 36 years with mean = 24.7±5.57. Sex: included 12 male and 8 female. Conclusion: Based on this study, it seems to us that the rhomboid flap is a good alternative for recurrent sacrococcygeal pilonidal sinus, especially for complex sinuses, and it could be appropriate for cases where simpler techniques have failed. It permits early return to complete activity, does not require prolonged postoperative attention, and has very low recurrence rate and postoperative morbidity which may compensate the inconveniences related to an unfavorable cosmetic look.
