To Assess the Effect of Trauma on the Temporomandibular Joint in Postoperative Cases of Zygomaticomaxillary Complex Fractures

Research output: Contribution to journalArticlepeer-review


Aim and Objectives: The study aims to assess the incidence and features of temporomandibular joint(TMJ) dysfunction in post-surgical treatment of unilateral zygomaticomaxillary complex(ZMC) fractures. The objectives are:1.To assess severity of TMJ dysfunction in postoperative cases of ZMC fractures.2.To create awareness of the same among clinicians. Methods: Patients presenting with zygomaticomaxillary complex fractures were evaluated prospectively. Evaluation of TMJ dysfunction was done by different parameters via questionnaire, clinical and radiographic examination preoperatively and a follow-up period of 1 week, 3 months and 6 months. The parameters were, clicking of joint, pain on opening /closing, pain on biting, deviation of mandible, pain in the preauricular region, ringing sound and mouth opening. Statistical analysis was done by the Friedman test and Post Hoc analysis. Results: On presentation, 69.1% patients diagnosed with ZMC fractures presented with symptoms related to TMJ dysfunction. Post-surgery 1 week majority findings persisted, with 21 patients complained of pain on opening or closing and 2 patients with a persistent opening click. These symptoms, however, decreased over the 3 month and 6 month follow up period. 5 patients presented with decreased mouth opening which was attributed to lack of adequate physiotherapy. Conclusion: Patients presented with mild symptoms of TMJ dysfunction until 6 months post-surgery, however these symptoms weren’t significant as the pain score assessed was found to decrease in the following post-operative periods. And the symptoms present were’nt exclusive to conclude a TMJ dysfunction. Early treatment and a close follow up are key to prevent progression of symptoms.
