A Case of Type 2 Diabetes Mellitus in Adolescent Presenting with Bell's Palsy

ABSTRACT

Bell's palsy is manifested by unilateral facial paralysis, but its cause is not clearly elucidated yet. Though the relationship between Bell's palsy and diabetes mellitus (DM) has been well established in adults, the relationship is not obvious in children and adolescents. Here, we report a case of adolescent Bell's palsy accompanied by DM. In this case, steroids were used for the treatment of Bell's palsy, and the blood glucose level in the patients was well controlled by metformin alone without additional use of insulin. We suggest that the presence of diabetes should be determined by blood test in the childhood and adolescent patients with facial paralysis, especially who are obese. As the use of steroids, however, is associated with the elevated blood glucose levels, it should be used with caution.
