Imaging-Guided Algorithmic Management of Mandibular Condylar Fractures: A 13-Year Institutional Analysis of 495 Joints.

(1)

Background

Mandibular condylar fractures continue to be a subject of debate, traditionally framed as a choice between open and conservative management. However, this binary approach fails to adequately account for fracture-level anatomy, Temporomandibular joint (TMJ) involvement, and functional outcomes. (2) Purpose: To present an imaging-guided, fracture-level-based algorithm that integrates radiologic evaluation, surgical approach selection, fixation biomechanics, and functional rehabilitation. (3) Review Strategy: This invited review combines current evidence with a 13-year institutional experience involving 495 joints. High-resolution Computed Tomography (CT) Imaging was used to assess fracture morphology, displacement, and ramal height, while Magnetic Resonance Imaging (MRI) was selectively employed in intracapsular fractures to evaluate disc-condyle relationships when intra-articular involvement was suspected. Management decisions, including surgical approach and fixation strategy, were guided by an institutional algorithm tailored to fracture characteristics. (4)

Results

Implementation of this approach yielded consistent and predictable outcomes. Mouth opening improved from approximately 18.77 mm preoperatively to 40 mm at 6 months. Lateral excursions became symmetrical (~9.6 mm), occlusion was restored in all patients, and bite force returned to near-physiological levels. Pain scores showed near complete resolution within 1 month. Postoperative morbidity remained low, with predominantly transient facial nerve weakness. (5)

Conclusions

This imaging-guided, algorithmic framework provides reproducible functional outcomes and signifies a shift toward structured, anatomically driven management of condylar fractures.
