Unilateral Submandibular Gland Aplasia with a Thyroglossal Duct Cyst

초록

The congenital absence of the submandibular gland is very uncommon, and might occur in association with other developmental abnormalities. Unilateral aplasia is reported more infrequently because it is usually asymptomatic, whereas the bilateral form often presents as xerostomia, dysphagia, and frequent dental caries because of decreased salivary flow. Submandibular gland aplasia with a concurrent thyroglossal duct cyst (TGDC) has not been reported. We report a case of unilateral submandibular aplasia that might be associated with a TGDC.
