Fig. 2. Preoperative radiography and postoperative magnetic resonance imaging (MRI). A. Preoperative radiographs of patient No. 1 showed homogenecity of the impacted mandibular third molars. B, C. Axial and coronal T2-weighted MRI of patient No. 1, performed seven hours after surgery, revealed more postoperative edema on the right side. Regarding the classification according to anatomic space, T2 hyperintense regions of edema were noted along the buccinator muscle on the left side (arrows), while edema was observed in the buccal space beyond the buccinator muscle on the right side. D. Preoperative radiographs of patient No. 2 showed homogenecity of the impacted mandibular third molars. E, F. Axial and coronal T2-weighted MRI of patient No. 2, performed five hours after surgery, revealed more postoperative edema on the left side than the right side. Regarding classification by anatomic space, edema was observed only in the buccinator muscle on the right side, while the edema spread to the buccal space beyond the buccinator muscle on the left side (arrows).
