Aims and objectives
In the study of lesions of the major salivary glands,
ultrasound is the initial choice technique.
It allows assessing whether a lesion is intraglandular or juxtaglandular,
characterize it morphologically,
delimit its borders and its vascularization by means of the Doppler study.
It also allows studying the adenopathies and in many cases it is enough to make the diagnosis.
It is done with high frequency transducers of 7-12 MHz,
using at least two perpendicular planes.
It also serves as a guide for FNAC (fine needle aspiration...
Methods and materials
Patient population: Retrospective observational analyses of patients were referred after physical examination by specialist or after visualization of the nodule by other imaging techniques.
In total 83 patients from our hospital with nodular lesions in major salivary glands (submaxillary or parotid) Period: November 2015 to November 2017.
Data acquisition: All patients underwent ultrasonography (with high frequency transducers,
12 MHz) of both parotids and submaxillary glands with acquisition of images in at least two perpendicular planes of the study lesion,
as well as Doppler US study....
Results
AGE RANGE
The age variable was categorized as qualitative and 5 groups were obtained according to the age range: (≤15,
16-35,
36-55.56-75,
≥76.) The largest number of patients belonged to the age range (56-75) and none was younger than 15 years.

SEX DISTRIBUTION
38 of the patients studied were men (46%) and 45 were women (54%)

Conclusion
The oncological antecedent significantly increases the probability that a salivary gland nodule is due to ‘’secondary’’ affectation.
The ultrasound has high sensitivity in the identification of the nodule but low specificity,
being difficult to distinguish tumoral pathology from inflammatory and benign from malignant.
USG- FNAC is a technique free of complications and with high profitability in obtaining material in solid appearance nodules.
Significantly increases diagnostic sensitivity versus isolated ultrasound
