Ultrasonographic measurements of parotid gland among poorly controlled type 2 diabetes mellitus Iraqi females sample

الملخص EN

Background : Unusual non inflammatory, non neoplastic enlargement of salivary gland and particularly parotid gland, frequently occur with underlying diseases which may be endocrine diseases.

The best known of these diseases include diabetes mellitus.

The B-scan ultrasonography is a generally accepted tool for determining parotid gland enlargement.

This study was established to determine the ultrasonographic measurements of parotid gland in poorly controlled type 2 diabetes mellitus female patients.

Subjects, Materials, and Method : This study was conducted on 140 parotid glands of 70 females participant , at age range ( 40-60) years, all of them were selected from subjects attending (Endocrine clinic for diabetic patients) Baghdad Teaching Hospital.

The body weight for both groups, must not exceeded 20% from the Ideal Body Weight (IBW), according Broca's formula (IBW = height-100).

Results : The statistical analysis showed that: The right-left mean difference in length, transverse, depth lateral to mandible , and depth dorsal to mandible US measurements of parotid gland among diabetic study group, revealed non statistically significant difference , similar result was obtained among control group, with only exception for the right-left mean difference in length, although this difference was state significant, but it was very small in a magnitude (-0.5 mm) with coefficient of variation (3.3%) only.

There was a statistically non significant weak linear correlation for US measurements of 4 parotid gland dimensions with aging for control group, while there was a statistically significant moderately strong positive linear correlation for US measurements with aging among diabetic patients.

Regarding to the age groups : (40-49) and (50-59) the mean US measurements among diabetic study group was always higher than controls at both age groups, and for study group such measurements were more porn to be statistically highly significant particularly in the older age group(50-59) p < 0.001.

Conclusion : These results provide new quantitative data demonstrating increase parotid gland dimensions as determined by ultrasonographic measurements in poorly controlled type 2 diabetic patients which is effectively reveals the parotid gland enlargement.
