PurposePilonidal sinus disease (PSD) is usually seen on the sacrococcygeal region in adolescent patients. The current study analyzed the outcome of the rhomboid excision and the Limberg flap procedure (cLF) in comparison to the modified Limberg flap procedure (mlF) for PSD.MethodsFour hundred and sixteen patients with PSD were operated on under spinal or general anesthesia by cLF and mlF. The patients were divided into two groups. In Group 1, cLF was performed on 211 patients. In Group 2, mlF was performed on 205 patients.ResultsNo significant difference was detected between Groups 1 and 2 in terms of sex, age, preoperative disease period, follow-up time, the mean hospital stay, and hypoesthesia. The mlF group had better clinical results than the cLF group. The recurrence rate was statistically higher in the cLF group 1 than in the mlF group (P = 0.036). The time to return to work, time to walk without pain, and time to be able to sit on the toilet without pain were longer in the cLF group (P = 0.001). The maceration and wound infection rate were statistically higher in the cLF group than in the mlF group (P = 0.020 and P = 0.019, respectively).ConclusionThe mlF is a more effective treatment than cLF for the surgical management of PSD.
