The maxilla and sphenoid bone are connected to each other through various structures, such as the pterygoid plates and the pterygomaxillary fissure.
So by extension, changes in the maxilla bone can potentially affect the sphenoid bone and its surrounding structures.
For example, maxillary expansion procedures like MSE, an aspect of this field, are commonly used in orthodontics to correct a narrow palate, that also end up affecting the position and shape of the sphenoid bone.
This is because the pterygoid plates, which are part of the sphenoid bone, are connected to the maxilla bone.
So as the maxilla bone is expanded, it can also push the pterygoid plates outward, which can result in changes to the position and shape of the sphenoid bone.
Similarly, trauma to the maxilla bone can potentially affect the sphenoid bone, as the two bones are connected through various structures. Severe trauma to the maxilla bone can also result in damage to nearby structures, such as the sphenoid bone, which can lead to more complex medical issues.
Let alone aesthetic problems.
In short, the maxilla and sphenoid bones are connected to each other through various structures, and thus changes in one bone could potentially affect the other - in this case, ergo maxillary modifications.
