Abstract
PURPOSE
While radiotherapy remains an essential part of the multidisciplinary treatment of cancers, it may cause unwanted consequences such as tissue break down and chronic non-healing wounds as a result of hypoxia, hypovascularity, and hypocellularity. The conservative treatment of osteoradionecrosis was effective only in the early stages or has a limited result. The surgical treatment of osteoradionecrosis includes various local fasciocutaneous flaps, local myocutaneous flaps and different kinds of free flaps with cancellous bone graft or alloplastic material after removal of all devitalized tissue. This study reviews recent cases of osteoradionecrosis in Severance hospital and investigates the use of various flaps for reconstruction of osteoradionecrosis. METHODS: From 2000 to 2006, a total of 29 patients, nine men and twenty women with a mean age of 60.4 years were identified and included in the study. Fasciocutaneous flaps were used on 7 patients and myocutaneous flaps were used on the remaining patients. Mean follow-up period was 10.4 months.
RESULTS
In the fasciocutaneous flap group, we noted two complications including total flap failure and a partial flap necrosis. In the myocutaneous flap group, four complications were noted including a partial flap necrosis and 3 cases of wound dehiscence. Considering the complications noted in this study, the natural history of progression to flap necrosis appeared to follow the following sequence of events: marginal flap necrosis, infection, wound dehiscence, flap floating and partial flap necrosis, serially.
CONCLUSION
Successful surgical treatment of osteoradionecrosis includes wide radical debridement and reconstruction with a well vascularized flap like myocutaneous flap or fasciocutaneous flap.
