Notas del editor
- one of a pair of large bones (often referred to as one bone) that form the upper jaw and teeth, consisting of a pyramidal body and four processes: the zygomatic, frontal, alveolar, and palatine. The maxilla is a bone that forms the upper jaw, part of the roof of the mouth and some bones of the nose. It also holds the upper teeth.
- The diagnosis process is in order Biopsy: Histopathological findings on hard palate biopsy showing diffuse chorion infiltration by a poorly differentiated carcinoma with a focal microglandular growth pattern (hematoxylin and eosin stain, ×400).

- Using some tissue taken from another part of your body (for example, your forearm, hip or lower leg) to rebuild the part that has been taken away. Another method involves filling the cavity (hole) with a skin, muscle and/or bone ‘flap’. This will be taken from another part of your body, for example, from your hip. Your surgeon will explain how this is done.
- For smaller tumours, the surgeon will reach the maxilla by making an incision in the roof of the mouth. This will leave a minor defect which can be left to heal or stitched closed. Larger tumours will be removed by cutting through the skin of the face, and this will leave a larger defect. There are two options to close this defect.
- Epiphora Watery eyes or an overflow of tears on the cheek is related to surgical swelling and is not uncommon following maxillectomy. As the swelling subsides, tearing generally also subsides.
