Only a few cases have been reported in the literature. Although this entity is usually asymptomatic, sometimes it may be important. For an example the normal parotid gland can be thought like a tumor due to the facial asymmetry. Accompanied by clinical and radiological findings, we present a case of unilateral parotid gland agenesis without involvement of other major salivary glands and together with a compensatory hypertrophy of the contralateral parotid gland.

Methods: The rats were randomly assigned to two groups: Group 1 is composed of 3G-EMR-exposed rats ( n = 9) and Group 2 is the control group ( n = 9). The first group was subjected to EMR for 20 days. The control group was not exposed to EMR. Choline (Cho), creatinin (Cr), and N-acetylaspartate (NAA) levels were evaluated by MRS. Catalase (CAT) and glutathione peroxidase (GSH-Px) enzyme activities were measured by spectrophotometric method. Histopathological analyses were carried out to evaluate apoptosis in the brain tissues of both groups. Results: In MRS, NAA/Cr, Cho/Cr, and NAA/Cho ratios were not significantly different between Groups 1 and 2. Neither the oxidative stress parameters, CAT and GSH-Px, nor the number of apoptotic cells were significantly different between Groups 1 and 2. Conclusions: Usage of short-term 3G MP does not seem to have a harmful effect on rat brain tissue.
