Unilateral Aplasia of Mandibular Condyle: A Rare Case Entity

Aplasia of the mandibular condyle is extremely rare when not seen in association with or as a part of any syndrome. The incidence is estimated to be 1 in 5.600 births. Growth disturbances in the development of the mandibular condyle may occur in utero late in the first trimester and may result in disorders, such as aplasia or hypoplasia of the mandibular condyle. We report a case of aplasia of left mandibular condyle along with hypoplasia of right condylar head in a 20-year-old female patent. The patient reported to the clinic with the complaint of proclined upper front teeth, wanting to improve her esthetics. Clinical, conventional radiography and computer tomographic studies revealed the complete absence of condyle on the left and hypoplasia of the head of mandibular condyle on the right side. The etiology was unknown and on the basis of history, clinical study and radiological examination it was suggested to be of developmental origin.
