CONGENITAL BONY TEMPOROMANDIBULAR ANKYLOSIS AND FACIAL HEMIATROPHY

Abstract

Bony or fibrous ankylosis of the temporomandibular joint is not a clinical curiosity, but a bony ankylosis of this articulation occurring in the new-born associated with maxillary and mandibular hemiatrophy is of sufficient rarity to warrant a report. <h3>REVIEW OF THE LITERATURE</h3> Numerous cases of bony intra-articular temporomandibular ankyloses, discovered in the early years of life, have been reported.¹In all instances in which the ankylosis was discovered within the first year of life or even in those instances in which it was discovered later without a definite history of postnatal trauma there was a history of a difficult forceps delivery. Langenbach,²prior to 1903, reported a case of bilateral bony ankylosis resulting shortly after a difficult forceps delivery. At the sixth year of life, arthroplasty was performed and a satisfactory functional result was obtained. Ballantyne³cited several cases of hemiatrophy of the mandible and maxilla and
