| ABSTRACTBackground: Unusual non inflammatory, non neoplastic enlargement of salivary gland and particularly parotidgland, frequently occur with underlying diseases which may be endocrine diseases. The best known of thesediseases include diabetes mellitus. The B-scan ultrasonography is a generally accepted tool for determining parotidgland enlargement. This study was established to determine the ultrasonographic measurements of parotid gland inpoorly controlled type 2 diabetes mellitus female patients.Subjects, Materials, and Method: This study was conducted on 140 parotid glands of 70 females participant , at agerange ( 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 statestical analysis showed that: The right-left mean difference in length, transverse, depth lateral tomandible , and depth dorsal to mandible US measurements of parotid gland among diabetic study group, revealednon statistically significant difference ,similar result was obtained among control group, with only exception for theright-left mean difference in length, although this difference was state significant, but it was very small in amagnitude (-0.5mm) with coefficient of variation (3.3%) only. There was a statistically non significant weak linearcorrelation for US measurements of 4 parotid gland dimensions with aging for control group, while there was astatistically significant moderately strong positive linear correlation for US measurements with aging among diabeticpatients. Regarding to the age groups: (40-49) and (50-59) the mean US measurements among diabetic study groupwas always higher than controls at both age groups, and for study group such measurements were more porn to bestatistically 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 asdetermined by ultrasonographic measurements in poorly controlled type 2 diabetic patients which is effectivelyreveals the parotid gland enlargement.Key words: Diabetes mellitus, parotid gland, Ultrasonography.
