Two miniplates versus 3-dimensional plate in the management of mandibular subcondylar fractures: a retrospective...

The aim of the present study was to evaluate the outcomes in patients with subcondylar fracture of mandible treated with 2 single miniplates compared to a 3-dimensional (3D) plate.

This is a retrospective study which included patients diagnosed and treated for mandibular subcondylar fracture from January 2015 to December 2019. Included patients were divided into two groups, group 1: 2 miniplate group and group 2: 3D plate group. The data was obtained from the patients' records and evaluated for various outcomes including occlusal stability, postoperative complications like plate fracture, non-union, plate or screw loosening, and plate or screw infection leading to implant removal, wound dehiscence, salivary fistula, and facial nerve paralysis. The statistical analysis was performed using chi square test and Student's t test.

A total 58 patients (43 males and 15 females) were enrolled in the two groups ranging from 21 to 59 years. A total of 35 patients were recruited in group 1, whereas 23 patients were recruited in group 2. There was no statistically significant difference in the two groups with regard to the age range, gender, diagnosis, side of fracture, and accompanying fractures. Occlusal instability, wound dehiscence, and facial nerve paralysis was found in both the groups. Group 1 had 1 patient which required implant removal due to screw loosing, whereas group 2 had 2 patients which required plate removal due to plate fracture. One patient in group 2 required second surgery for fixation of fracture due to non-union. One patient in group 1 developed a sialocele postoperatively. However, there was no statistically significant difference in any of the variables assessed among the two groups (p > 0.05).

The results of our study indicate that the 2 miniplates and 3D plate system are effective in the management of mandibular subcondylar fractures.
