摘要

Objectives

The aim of this prospective study was to evaluate and compare the survival rate of reconstruction plate used in the management of mandibular continuity defects in patients with and without coronoidectomy.

Study Design

A single centre, randomized, parallel group, single-blinded prospective clinical trial was conducted on Fifty-four patients, who were divided randomly into two groups (Group A and B) of 28 patients each. All the patients underwent segmental mandibulectomy followed by mandibular reconstruction with reconstruction plate, in addition, ipsilateral coronoidectomy was done in group B patients alone. The patients were assessed at four intervals such as immediate post-operative day (Post-operative day 1), 3 months, 6 months and 12 months after surgery, for parameters like maximum inter-incisal mouth opening (MIMO) and reconstruction plate related complications (RPRC).

Results

The results revealed that that the MIMO measurement at any time period was higher in the patients who underwent coronoidectomy. It was also observed that the incidence of RPRC was higher in patients who did not undergo coronoidectomy. It was observed that the overall plate fracture was more in Group A (51.85%) than in group B (22.22%), with a statistically significant difference.

Conclusion

Since it is evident from the present study that ipsilateral coronoidectomy delays plate related complications and the procedure is not associated with any complications, it may be considered in every case of mandibular reconstruction with reconstruction plate.
