Abstract
Purpose The aim of this study was to investigate capability of ultrasonography (USG) as an alternative imaging method to MRI in detection of fascial space spread of odontogenic infections. Materials and Methods Forty-seven fascial spaces out of twenty subjects, clinically-diagnosed as odontogenic infections, were included in this prospective study. The fascial space involvements were examined using ultrasonography( USG) and magnetic resonance imaging (MRI) and the results were confirmed with microbiology tests. Results USG demonstrated 37 (78.7%) of 47 involved fascial spaces. There was 100% agreement between USG and MRI on 37 superficial space involvements, including 15 buccal (BS), 12 Submandibular (SMn.S), 6 canine(CS), 2 submasseteric(SMS), one submental (SMt.S), and one infraorbital (IOS)spaces. USG did not detect the 4 masticator (MS) spaces and all 4 parapharyngeal (PPS) space involvements. USG was able to stage infections starting from edematous change to cellulitis to complete abscess formation. Conclusions USG could be considered as an effective method in detecting and staging spread of odontogenic infections to the superficial fascial spaces such as buccal, submandibular, and canine spaces. However, it was difficult to detect deep fascial space involvements.
