Abstract :
Maxillary sinus grafting is a well-know procedure that has been used for
a long time with high predictability in order to correct vertical bone
defects in the posterior region of the maxilla.
While the crestal approach is
indicated in moderate vertical defects, the lateral approach is used
when facing severe maxillary atrophy with a residual ridge hight
inferior to 6mm.
Some benign tumors can develop inside of the paranasal cavities such as
osteomas. They present as a slow-growing, usually asymptomatic lesions,
characterized by proliferation of compact or cancellous bone. they
commonly occur in the frontal sinus, followed by the ethmoid and
maxillary sinus. It’s rarely encountered in the sphenoid sinus.
The presence of a sinus osteoma can be a challenge if a sinus floor
elevation procedure must be performed. To our knowledge, this is the
first case report of a maxillary sinus grafting in presence of a sinus
osteoma.
