Abstract
Dysfunction and aesthetic disorders in the oromandibular region caused by surgical resection cannot be restored to the presurgical state. It is essential to reconstruct a new functional system that matches the defect and can be accepted by the patient after surgery; this is called functional unit reconstruction. In aesthetics, it is crucial to reconstruct the patient’s new facial contours to be acceptable after surgery, which is called framework reconstruction. From the perspective of functional unit philosophy, we know that effective functional reconstruction is not possible by reconstructing the oromandibular region organ-by-organ, one organ at a time, such as the tongue, floor of the mouth, or mandible. It is important to consider the importance of each organ in the overall function of the oromandibular system and to reconstruct it as a functional complex. To reconstruct oromandibular function, oral and maxillofacial surgeons, plastic surgeons, head and neck surgeons, and maxillofacial prosthodontists must share a common understanding of the major themes of “What is eating?” and “What is the facial appearance that patients can accept after surgery?”, and be aware of the aims and objectives of the reconstruction. To achieve this, surgeons must have a deep understanding of oromandibular functions, including masticatory and temporomandibular joint functions. In addition, mandibular reconstruction is facial reconstruction. For this reason, surgeons must have a clear idea of the new facial framework that the patient will accept after surgery.
