Perineum and groin constitute only 4–6% of total body surface area and are very important sites in the body anatomically and functionally. Isolated burns to the genitalia and perineum are not common. These burns are of major concern to the patient as well as clinician. Flame burns and scalds are common causes of perineal and genital burns. Alcoholism is considered to be one of the leading predisposing factors in perineal and genital burns.
Materials and Methods: This is prospective and descriptive study conducted in the Department of Plastic Surgery at JSS Medical College, Mysuru over a period of 1 Year. First dressing was seen on third or fourth postoperative day and percentage of graft take/loss was noted. Complications, if any, were recorded. Indwelling urinary catheter drainage was instituted for 3 to 4 days postoperatively. Once the graft stabilized, patients were discharged and advised to wear compression garments.
Results: In our 68.5% of the patients, post burn contractures of the groin and perineum were because of Open chulla. Other less common causes were hot water (17.1%) and flame burn (14.2%). Majority of the patients were brought with complaints of difficulty in squatting (65.7%) followed by limitation of movements of hip joints (54.2%) and (48.5%) impairment of walking. In our study of 35 patients two types of operative procedures were performed: (1) release of contracture with split thickness skin grafting; (2) release of contracture and closure by multiple Z-plasties. Moreover, 17 (48.5%) patients having bilateral groin contractures underwent release of contracture with split thickness skin grafting. 13 (37.1%) patients underwent release of unilateral groin contracture with split thickness skin grafting and 3 (8.5%) patients underwent release of unilateral groin contracture and closure by multiple Z-plasties. 2 (5.7%) patients with perineal contracture only underwent release of contracture with split thickness skin grafting.
Conclusion: In our study, satisfactory functional and cosmetic results were seen with split thickness skin grafts in patients having postburn contractures of groin and perineum.
