Summary

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 bridge and clinoid enlargement with respect to sex, and age groups (under 18 and over 18). The sella turcica bridge and clinoid enlargement are not so infrequent findings in the population studied, our results are similar to those reported in the literature. The existence of a sella turcica bridge or a clinoid enlargement must be considered as a structural anomaly that may influence the prognosis of surgical procedures of the sella turcica.
