ORN usually manifests with pain, exposed bone, fistulae and pathological fracture and the proper management needs proper debridement and coverage by thick musculocutaneous flaps. Objective: To evaluate different techniques of surgical management of post-irradiation persistent radio-necrotic ulcer & ORN with emphasis on the outcome of each technique. Patients and methods: A retrospective study from 2010 to 2015 reviewed 20 patients subjected to post-mastectomy radiotherapy as a treatment for breast cancer inNCICairo, and Minia oncology center Hospital, Egypt. Cases were biopsied to exclude local recurrence. The age, sex, type of ulcer, dose of radiotherapy received and the management done for these cases were recorded. Results: Only 4 patients responded to conservative treatment in the form of repeated dressings, and 16 patients needed surgical treatment;5 of them were treated with debridement and coverage with split thickness graft with high rate of complications reaching 80%, the other 11 patients were reconstructed with musculocutanoeus flaps, of these 7 patients were reconstructed with LD flaps with 57.14% success rate and minor complications only, the other 4 cases were reconstructed with TRAM flap with 50% success and major loss of the flap in one case that needed salvage by LD flap. Pre-operative comorbidity was found in 6 patients and all of them experienced complications while only 3 of the other 14 who had no comorbidity had postoperative complications. Conclusion: Pedicled flaps provide a good choice for reconstruction and provide chest wall support without the use of synthetic mesh.展开更多

We have reviewed the literature concerning the experimental irradiation of facial bones in animals. Materials and Methods: A PubMed search was performed to retrieve animal experiments on the irradiation of facial bones that were published between January 1992 and January 2012. The search terms were “irradiation facial bone” and “irradiation osteoradionecrosis”. Results: Thirty-six publications were included. The irradiation sources were Cobalt60, orthovoltage, 4 - 6 megavolt photons, and brachytherapy. The total dose varied between 8 - 60 Gy in single or multiple fractions. The literature presents a broad range of animal studies that differ in terms of the in vivo model, irradiation, observation period, and evaluation of results. Discussion: The different animal models used leave many questions unanswered. A detailed and standardized description of the methodology and results would facilitate the comparability of future studies.展开更多
