Repair and Reconstruction of Maxillary Defects

The maxilla is the cornerstone of the appearance and function of the midface and has important functions such as supporting the skull base, eyeballs, and midface, bearing the chewing force, and separating the oral and nasal cavities. The main causes of maxillary defects include acquired defects caused by tumor-reductive surgery and severe trauma and the congenital developmental malformations. The effect of the maxillary defect on the appearance and function of the patient counts for much, the maxillary defect is often accompanied by the destruction or deletion of surrounding vital structures, and therefore it will cause facial deformities and severe loss of oral functions, bring catastrophic blow to the patient’s physiology and psychology, and seriously affect the quality of life of patients.
