Fig. 2.

CBCT scan for digital implant planning with large FOV (10 × 10 cm) in a partially edentulous 79-year-old male patient. Opacification (over 50%) of the partially imaged left maxillary sinus antrum with inhomogeneous osseous appositions basally and absence of the left lateral nasal wall is conspicuous. In the right maxillary sinus, an opacification was present in the lower half of the antrum. Due to the incidental findings in the maxillary sinuses, further evaluation by an otorhinolaryngologist was indicated. Sagittal (A), coronal (B) and axial (C) images
