Korea has achieved rapid industrialization and economic development through the export drive policy since 1960. But these developments gave rise to serious occupational disease, pollution and other health problems. Because occupational disease originate from occupation and work environment unlike common diseases, the society has felt a great interest in occupational disease. In 1988, the number of cases of occupational disease in Korea was 8,919 among the 54.,000 cases of workers physical examination, and detection rate was 1.64%. Workers physical examination system is enforced, under the requirements of Occupational Safety and Health Law. For the judgement of disease due to occupational hazard, it is necessary to consider below items. 1) work character and working hours 2) working environment (threshold limit value of hazard substance) and health effect of hazard substance 3) specific clinical symptoms 4) incubation period 5) past history 6) differential diagnosis from other non-occupational cause 7) detection of other patient having similar symptoms 8) measurement of hazard substance and metabolite in blood and urine

The successful reconstruction of the soft tissue defects in the perineum(external genitalia and perianal area) has long been a very troublesome procedure, because this anatomical region is susceptible to the problems of skin maceration, urinary and fecal contamination, fistulization and infection, leading to delayed or incomplete wound closure. Moreover aften incomplete wound healing with inadequate skin flap there will be a functional deficit in the genitalia and bowel habit. Additionally multiple procedures would be necessary for the perineal reconstruction, even though the ill and debilitated individuals with infected perineal wound need a single staged reconstruction with minimal donor defects. The muscle and myocutaneous flaps can afford a simple, safe, one stage method for reconstruction of such defects in the perineum. We have present 11 cases of perineal soft tissue defect(external genitalia and perianal area) which were repaired by myocutaneous flaps. Among 11 cases were repaired by the gracilis myocutaneous flaps, 3 by the gluteal thigh flaps and 1 by the glutealthigh flap combined with gracilis myocutaneous flap. We will discuss the advantages and disadvantages of these two flaps in the perineal reconstruction.
