Yes nice to meet you.
I can't see (X-ray), so I can't tell you exactly, but it's possible enough.
Of course, the first operation is a little difficult, but think about the principle.
According to the maxillary sinus endoscopic observations, even though the maxillary sinus appears flat in the pano (x-ray), the buccal tract has a valley shape, which means that the flat maxillary sinus elevation is not likely to be damaged.
As expected, a 5 – 2.7 mm narrowing slope is not a major problem for hatch reamer surgery.
The bone chip that is made while the hatch opens and opens along the inclined surface naturally pushes into the upper maxillary sinus and can be operated easily without additional bone graft.
I think it's worth a try.
Thank you.
