Role of Local Flaps to Achieve Primary Wound Closure in Medication-Related Osteonecrosis of the Jaws Osseous-Resective Surgery.
2020
The aim of the present work is to evaluate the most suitable surgical technique in relation to location and extent of medication-related osteonecrosis of the jaws (MRONJ) through comparison of success rate between the routinely used mucoperiostal flaps and different local flaps designs and propose a standardization of surgical procedures according to MRONJ stage and localization with 2 objectives: to provide the surgeon with an algorithm of treatment according to MRONJ localization and extension; to maximize the success of surgical treatment.Thirteen consecutive patients affected by focal MRONJ were surgically treated with radical osteotomy at the Center for Treatment of the Osteonecrosis of the Jaws (University of Messina, Italy).Initial defects were classified according to the classification of the Italian Societies of Oral Medicine and Maxillofacial Surgery (the SICMF-SIPMO staging system) which consider not only bone exposure but also radiological bone involvement. Treatment outcome was retrospectively assessed according to the different adopted surgical procedure: mucoperiostal flaps (GROUP A) advanced mucoperiostal flaps or rotation flaps (GROUP B) local flaps (GROUP C).Outcome after surgical treatment of focal MRONJ was positive in every group irrespective of MRONJ localization and extension. This may be due to the appropriate selection of surgical procedure.The results obtained demonstrated that focal MRONJ surgical treatment is a reliable procedure irrespective of the initial clinical situation. Radical osteotomy combined with appropriate selection of soft tissue management is crucial.
