Introduction: Temporomandibular joint dislocation is described as the movement of mandibular condyle out of the fossa beyond its anatomical and functional boundaries causing pain and discomfort. It is often managed by conservative methods, but in long-standing, chronic conditions, surgical treatment is the only option. The goal of surgical treatment is to reposition the condyle and prevent further recurrences. Materials and Methods: This retrospective analysis involving a single center and a surgeon with 19 patients and 23 joint surgeries performed over a 10-year period. Patients who fulfilled inclusion and exclusion criteria and had earlier undergone surgical correction with hook-shaped miniplates and miniscrews fixed with or without bone grafts formed the study group. Results: In all, 12 were female (mean age, 41.9 ± 12.07 years) and the rest 9 were male (mean age, 39.8 ± 13.6 years), ranging from 32 years to 58 years. All patients had the dislocation for an average period of 19.26 ± 12.6 months before the surgery. The mean maximal mouth opening (without pain) preoperatively was 17.78 ± 2.13 mm (12–25 mm) while postoperatively it was 32.28 ± 3.17 mm (27–37 mm). There were no immediate or late surgical complications in the follow-up period that ranged from 8 to 37 months. Discussion: When proper case selection is employed and properly done, using hook-shaped miniplates with or without bone graft is more cost-effective, giving excellent short- and long-term effects. Conclusion: The results in this Indian population are very similar to that reported from other parts of the world.
