Frequency of Ponticulus Posticus in Lateral Cephalometric Radiography of Peruvian Patients International Journal of Morphology
Pérez,Iván E; Chávez,Allison K; Ponce,Darío.
The Ponticulus posticus is an anomalous ossification of unknown origin that arches backward from the superior articular process to the posterior arch of the Atlas vertebra, it can be complete or partial and houses vascular and nervous elements; it is diagnosed by lateral cervical radiography, cephalometric radiography or CT scans. The purpose for the present study was to determine the frequency of partial and complete Ponticulus posticus in lateral cephalometric radiography of Peruvian patients and identify any possible genre or age group associations. The study consisted in reviewing 1056 lateral cephalometric radiography of patients between 3­56 years old in search of partial or complete Ponticulus posticus. The mean age of subjects studied was...

Frequency of Ponticulus Posticus, Sella Turcica Bridge and Clinoid Enlargement in Cleft Lip and Palate Peruvian Patients: A Comparative Study with Non-Cleft Patients International Journal of Morphology
Pérez,Iván E; Chávez,Allison K.
The aims of this study were to determine the frequency of the Ponticulus posticus (PP) in the C1 vertebra and the Sella Turcica Bridge (STB) and Clinoid enlargement (CLEN) variants in two samples of Peruvian cleft lip and palate patients (CLP), determine if there are significant differences between sexes and compare the results with two samples of non-cleft controls. The digital images of the lateral cephalometric radiography of 163 and 150 CLP patients were utilized to determine the frequency of PP and, STB-CLEN respectively. The controls were composed of 1056 and 417 radiography of non-cleft patients. The chi-square statistic was utilized to determine if there were significant differences between genres for the CLP patients, and between the CLP and...

Frequency of Sella Turcica Bridge and Clinoid Enlargement in Lateral Cephalometric Plain Film Radiography from Peruvians International Journal of Morphology
Pérez,Iván E; Chávez,Allison K; Ponce,Darío.
The purpose for the present study was to determine the frequency of sella turcica bridge and clinoid enlargement on lateral cephalometric plain film radiography from peruvians patients who attended our radiological center and identify any possible genre or age group associations. The sella turcica from 417 lateral cephalometric plain film radiography was evaluated in order to determine the presence of sella turcica bridge (fusion between the anterior and posterior clinoid process) or clinoid enlargement related to the Sella (S) cephalometric point. The sella turcica bridge and clinoid enlargement frequency was 4.31% (n=18), and 16.3% (n=68). Cramer´s V and ETA statistics found, by separately, non significant association (p > 0.05) between sella turcica...
