 Some sequences are motion degraded, limiting fine detail. No significant susceptibility is identified in the area of concern. In the surgical defect along the lateral left maxillary alveolar process, there is ill-defined low T1 signal mild and associated effacement of the fat, as well as mild ill-defined enhancement which is nonspecific and may be postoperative in etiology or represent an inflammatory process. There is otherwise no discernible abscess or fistula tract, although some areas of subtle irregular perhaps minimally linear enhancement might be suggested in this area on prior CT. There are several absent left maxillary teeth.There is minimal mucosal thickening of the maxillary sinuses bilaterally. There is trace mucosal thickening in the anterior ethmoid air cells. There is mild leftward deviation of the nasal septum. There is fluid in the mastoid air cells bilaterally, right greater than left.
1.Ill-defined low T1 signal and mild enhancement in the surgical defect correlates with asymmetry in same area on previous CT, and may be postoperative in etiology or represent an inflammatory process. 2.No definite evidence of abscess or sinus tract as clinically questioned.
