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.
