Abstract

Purpose: To estimate the clinical significance of the infraorbital space demonstrated on CT for the diagnosis of odontogenic infection caused by periapical lesions of the maxillary canine tooth.<BR>Materials and methods: We evaluated the radiological appearance of the labial cortical bone and the surrounding soft tissue adjacent to the root apex of the maxillary canine in 12 patients with infraorbital space infection demonstrated on CT. The patients consisted of 6 males and 6 females, and age ranged from 33 to 84 years with a mean age of 58.7 years.<BR> Results: On CT, disruption of the labial cortical bone around the root apex of the maxillary canine accompanied with pathological soft tissue density adjacent to the disrupted cortical bone was observed in all of the cases. Swelling of the facial muscles (levator labii superioris muscle, levator anguli oris muscle) was shown in 6 (50%) of 12 cases. Deviation of the levator labii superioris muscle was demonstrated in 9 cases (75%), whereas that of the levator anguli oris muscle was observed only in 2 cases (17%).<BR>Conclusions: The anatomical appearance of the infraorbital space which is clearly demonstrated on CT might be useful in diagnosing the spread of odontogenic infection caused by periapical lesions of the maxillary canine.
