Objective
To calculate the prevalence of ponticulus posticus and its association with headache.
Methods
The presence and types of ponticulus posticus were investigated on 640 digital lateral cephalograms. Patients with complete or partial ponticulus posticus were further evaluated and questioned for a history of cervicogenic headache. Dissemination of attain values was analyzed using a Chi-Square test, and p values < 0.05 were considered statistically significant.
Results
The prevalence of ponticulus posticus in our study was 9.8%, with complete form in 45 (7%) patients of which 29 (64.5%) were male and 16 (35.5%) were female. Partial ponticulus posticus was found in 18 (2.8%) of patients, of which 12 (66.6%) patients were male and six (33.33%) were female. In patients with the complete form of ponticulus posticus, 37 (82.22%) were symptomatic. Among these 37 patients, 22 (59.45%) were male and 15 (40.54%) were female. In complete ponticulus posticus patients, symptoms were slightly worse in males than females. Whereas in partial ponticulus posticus, 13 (72.22%) patients were found to be symptomatic. Of these 13 patients, seven (53.84%) were male and six (46.15%) were female. Of the 72 patients with a history of cervical pain, 50 (69.44%) showed ponticulus posticus on a lateral cephalogram. Of the 568 patients with no history of cervical pain, only 13 (2.2%) showed ponticulus posticus on the lateral cephalogram.
Conclusion
This study examination showed that ponticulus posticus is a common anatomic variation often associated with tension-type headaches.
