ResumoReconstruction of the mandible is particularly challenging because of its complexity and unique characteristics. The mandible is a unique bone for many reasons. It has significant impact on facial harmony from a cosmetic standpoint and is extremely diverse in function. The mandible not only bears half of the dentition, but it also is responsible for mastication, it contributes to speech and swallowing, and it supports the tongue base to maintain a patent airway. During function, the arch form expands or contracts, varying with the degree of opening and the influence of the muscles of mastication. 1 McDowell JA Regli CP A quantitative analysis of the decrease in width of the mandibular arch during forced movements of the mandible.

It is divided into multiple segments including the condyle, condylar neck, coronoid process, ramus, alveolar process, and the basal mandible, all of which have unique internal and external architecture and function. The vascular supply to the mandible is 2-fold, with both internal (inferior alveolar artery) and external (periosteal) circulatory systems. Recurrence rates in oral cancerJournal of Oral and Maxillofacial SurgeryVol. 60Issue 7PreviewThere is a misleading error in Steven R. Schimmele's article, “Delayed Reconstruction of Continuity Defects of the Mandible After Tumor Surgery” in the November 2001 issue (J Oral Maxillofac Surg 59:1340, 2001). Dr Schimmele states that “seventy percent of these lesions (squamous cell carcinoma [SCC]) will recur in the first postablative year” and goes on to call this a “70% recurrence rate.” According to information from lectures, papers, and chapters by Robert Marx, 65% to 70% of oral SCC patients who have a recurrence will have that recurrence within 1 year of their ablative surgery.
