Objective:
The purpose of this study was to investigate the prevalence of ponticulus posticus (PP) in patients with migraine.
Study Design:
The 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.
Results:
PP 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).
Conclusions:
Significant 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.
