Background: Eagle's syndrome comprises a rare disorder caused by compression of an elongated or deformed styloid process or ossified/calcified stylohyoid ligament on neural and vascular structures. It is characterized by facial and neck pain and can be confused with a wide variety of facial neuralgias, oral and dental diseases and temporomandibular disorders. An imaging evaluation associated with a careful clinical examination, are mandatory in structuring a correct differential diagnosis and in the establishment of a proper therapeutic protocol.
Aim: To investigate the prevalence of the elongated styloid process in a Central Brazilian population and its relation to gender, age and side.
Materials And Methods: Digital panoramic radiographs of 736 patients (412 female and 324 male, with a mean age of 35.03 years) were consecutively selected from a private radiology clinic's secondary database. The apparent length of the styloid process was measured from the point where the styloid left the tympanic plate to the tip of the process by two specialists in dental radiology, with the help of the measuring tools on the accompanying software. Styloid process measuring more than 30 mm was considered elongated. The statistical analysis included frequency distribution and cross tabulation. The data were analysed by using Chi-squared tests. The level of significance was set at 5% for all analyses.
Results: A total of 323 (43.89%) radiographic images were suggestive of elongated styloid process. No statistically significant difference was found between the genders, although a higher prevalence was noticed in female participants. Approximately, 31% of the elongated styloid process was observed in 18-53-year-old participants (p < 0.05). Two hundred and sixty seven styloid processes (36.28%) were elongated on both right and left sides.
Conclusion: The prevalence of elongated styloid process was high and no statistically significant correlation was found between the presence of elongated styloid process and the studied variables with the exception of the age.

Division of Oral Radiology, School of Dentistry, Federal University of Ceará, Fortaleza, Ceará, Brazil.
Purpose: This study aimed to assess the styloid process (TBSP) phenotype and to identify suggestive images of calcified atheromatous plaques (CAP) in panoramic radiographs of patients with primary hyperparathyroidism (PHPT) and post-surgical hypoparathyroidism (hypoPT). Additionally, it aimed to analyze the association between the bone mineral status of patients with parathyroid diseases and the radiographic findings.
Material And Methods: A cross-sectional case-control study was conducted with individuals diagnosed with PHPT (n = 25) and post-surgical hypoPT (n = 25).

Article Synopsis
- The study examines the superficial palmar branch of the radial artery (SUPBRA) to improve techniques for reconstructing palmar skin, focusing on its anatomy and harvesting methods.
- Researchers dissected 19 male hand specimens to gather detailed anatomical data, including dimensions and positions of key structures related to SUPBRA, analyzing how best to utilize this flap in reconstruction efforts.
- Results indicated that the SUPBRA has adequate dimensions for viability in surgical applications, with specific measurements and the identification of critical vascular contributions that ensure successful use in cases of hand injury.
