Oral and maxillofacial radiologyEvaluation of ponticulus posticus on digital lateral cephalograms and cone beam computed tomography in patients with migraine and healthy individuals: a comparative study

ObjectiveThe purpose of this study was to investigate the prevalence of ponticulus posticus (PP) in patients with migraine.Study DesignThe presence and types of PP were investigated in 100 patients with migraine and 100 healthy controls on digital lateral cephalograms and cone beam computed tomography (CBCT) scans.ResultsPP was found in 42% of the patients with migraine and in 19% of the healthy controls on digital lateral cephalograms. CBCT scan found PP in 40 patients with migraine and in 18 healthy controls. The agreement between the occurrence of PP seen on digital lateral cephalograms and that seen on CBCT images was “very good” (κ = 0.92).ConclusionsSignificant association was found between PP and migraine. PP is easily visible on lateral cephalograms. For a more accurate diagnosis, CBCT is required. Therefore, radiographic detection of PP must be considered an important task, because this anomaly may be a key indicator of an underlying disease process.
