[Indications for mandibular periosteotomy in the treatment of cancer of the oral cavity].
Marginal mandibulectomy is a compromise between preserving the mandibular structure and radical oncological surgery. In order to evaluate the correctness of the indications for this operation, a group of 47 patients with oral carcinoma underwent direct surgery or associated chemoradiotherapy and surgery. Surgery was programmed on the basis of clinical and radiological examinations and the specific evaluation of the distance of the tumour mass from the mandibular surface. This approach was justified by the lack of correlation, in anatomic and clinical terms, between tumoral infiltration of the mandible and metastatic recurrence in the cervical lymph nodes. Lastly, the varying pattern of tumoral invasion of the various mandibular regions (thickness of cortical bone, presence of foramen) induced the authors to distinguish the indications for conservative treatment by segments. According to international literature and on the basis of the authors' past experience, marginal mandibulectomy represents an extremely interesting method since it associates a satisfactory aesthetic-functional level with a radical oncological approach, in particular with regard to the symphyseal and parasymphyseal region owing its structural characteristics and reconstructive importance. The indications for this type of surgery are therefore in theory based primarily on oncological aspects, and subsequently on the various anatomic and reconstructive aspects of the various mandibular segments.
