Background:
To study the rarity of mandibular coronoid process fractures and treatment strategies based on the displacement of these fractures.
Materials And Methods:
A retrospective study of 11 cases of coronoid process fractures among 307 treated cases from 2008 to 2013 was conducted. Six patients were treated conservatively and 5 underwent ORIF with associated fractures. A statistical analysis of the data obtained after subjective and objective evaluation was done.
Results:
The incidence of coronoid process fractures was 3.58% of all mandibular fractures analyzed. There was no statistically significant difference found between two treatment modalities, but differences in maximum interincisal opening (MIO) and pain in the postoperative period were significant.
Conclusion:
We recommend that linear coronoid fractures with minimal displacement can be managed with conservative treatment. For patients with significant displacement of coronoid process, limited mouth opening or concomitant mid-face or lower-face fractures, rigid internal fixation is recommended.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
