Unilateral aplasia of the Submandibular gland : Two cases report

Aplasia or agenesis of the salivary gland is an uncommon disorder. Unilateral aplasia of the submandibular gland is an extremely rare disorder. Salivary gland aplasia may occur either in isolation or in association with other developmental anomalities, such as atresia of the lacrimal pucta, mandibulofacial dysostosis or congenital malformations of the temporomandibular component. Clinically, patients may be asymptomatic or may present with dryness of the mouth, difficulty in swallowing, and dental caries. The authors experienced two cases of incidentally detected unilateral aplasia of the submandibular gland demonstrated by computed tomography. So we present this cases with review of literatures.
