This study found no significant link between ponticulus posticus (PP) and elongated styloid process (ESP) in Iranian patients. Cone-beam computed tomography (CBCT) imaging was used to analyze cervical vertebrae variations and their association with symptoms. Further research may explore other contributing factors.
Area of Science:
- Anatomy
- Radiology
- Medical Imaging
Background:
- Ponticulus posticus (PP) is a cervical vertebra variation that can mimic Eagle syndrome symptoms.
- Elongated styloid process (ESP) is another anatomical variation with potential clinical implications.
Purpose of the Study:
- To investigate the relationship between ponticulus posticus and elongated styloid process in an Iranian patient cohort.
- To utilize cone-beam computed tomography (CBCT) for detailed anatomical assessment.
Main Methods:
- CBCT scans of 349 patients (118 males, 231 females) were analyzed.
- Atlas vertebra was examined for PP (partial/complete) in sagittal views.
- Styloid process evaluated for ESP in panoramic and 3D reconstructions.
- Statistical analysis included Mann-Whitney, Fisher's exact, and Chi-square tests.
Main Results:
- Ponticulus posticus prevalence was 24.5% in patients with ESP and 31.98% without ESP.
- No statistically significant relationship was found between PP and ESP (p = 0.198).
- Bilateral ESP and PP were observed in 14.70% of cases, with a higher mean age.
Conclusions:
- The study concluded no significant association between ponticulus posticus and elongated styloid process.
- Prevalence and characteristics of PP did not show a significant relationship with ESP in the analyzed population.

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
