Prevalence of Different Patterns of Temporomandibular Joint Ankylosis in South Indian Population

Abstract

The aim of this study was to identify the incidence of different patterns of temporomandibular joint
ankylosis in the south Indian population. Case records of a total of 86000 patients between June 2019 and
March 2020 were collected and analyzed from patient records, out of which a total of 7 cases of mandibular
temporomandibular joint ankylosis cases who had undergone treatment for the same were identified and
included in the present study. All these were checked retrospectively for pattern/type of ankylosis by using
the radiographs with Sawhney’s classification. Results show that there’s a significant male predilection of
about 85.7% and shows more unilateral ankylosis cases of about 57.1%. Based on Sawhney’s classification
it shows 14.3% of type - 1 cases, 42.9% of type - 2 cases, 28.6% of type - 3 cases and 14.3% of type - 4
cases. Within the limitations of this study, it showed that there was a male predilection, unilateral ankylosis
cases were common, and among all ankylosis cases Sawhney’s type 2 temporomandibular ankylosis cases
were high in number.
