Unilateral Ankylosis of Temporomandibular Joint (TMJ) with Contralateral Condylar Aplasia and Related Orthopedic Deformity – Syndromic or Nonsyndromic?

Abstract

Condylar aplasia which means “failure of development” is a rare condition and can be unilateral or bilateral. Mandibular condylar Aplasia without any association with syndrome is extremely rare. Temporomandibular joint (TMJ) ankylosis results from trauma, infection and inadequate surgical treatment of the condylar area. Congenital cases are very rare. We report case of congenital unilateral aplasia of left mandibular condyle with ankylosis of right condyle, with an associated orthopedic deformity in a nine-year-old male patient, which may be a part of some unreported syndrome that has not been mentioned so far in literature. As per our best knowledge, no other case including such clinical features has been reported.
