[Anatomo-radiological study of the cranio-cervical region in 60 students from Universidad de la Frontera, Chile].
BACKGROUND
Twenty to thirty percent of the population has craniomandibular anomalies, that are closely related to craniocervical disorders.


OBJECTIVE
To evaluate the craniocervical region from a radiological point of view in healthy young adults.


METHODS
A lateral head and neck radiological study, using the technique described by Rocabado, was done to 60 Chilean young adults, aged 19 to 24 years old.


RESULTS
The cervical curvature was altered in 70% of subjects (kyphosis in 35%, straightening in 33.3% and lordosis in 1.7%). Sixty eight percent had alteration of the hyoid triangle (in the plane in 31.7% and inverted in 37%). The distance between CO and C1 was altered in 48% (less than 4 mm in 15% and more than 9 mm in 33%). An altered posteroinferior angle was observed in 40% (less than 96 degrees in 30% and over 106 degrees in 10%).


CONCLUSIONS
A high percentage of alterations of the craniocervical region was detected in healthy adults.
