Giant schwannoma of the hard palate: a literature review and report of an uncommon case.

Schwannomas (also known as neurilemomas) are benign tumors that arise from the Schwann cells of the nerve sheath. While they seldom occur in the oral cavity, the tongue is the most common site. Palatal schwannomas are extremely rare.

Prevalence of pathologic findings in the floor of the maxillary sinuses on cone beam computed tomography images.

This study evaluated pathologic findings in the floor of the maxillary sinuses on cone beam computed tomography (CBCT) images. CBCT scans of 500 subjects, mainly taken for dental implant planning, were evaluated. The pathologic findings in the 1000 maxillary sinuses (left and right) were categorized into 4 classes: mucosal thickening, mucous retention pseudocyst, partial opacification, and total opacification.
