Endoscopic assisted management of mandibular extracapsular condylar fractures: A prospective randomized controlled study

Study design: Endoscopic-assisted open reduction internal fixation (EAORIF) is currently replacing conventional open
reduction internal fixation (CORIF). It is claimed that it offers prompt recovery with comparable results while diminishing the
risk of facial nerve injury and sparing facial scars.
Objective: The current prospective randomized controlled trial aimed to compare the efficacy of both techniques against their
risks.
Methods: Twelve patients suffering unilateral displaced condylar fractures were equally divided into CORIF and EAORIF.
Both groups; condylar fractures were fixed using a standard plate 4-hole maxi plate. Clinical assessment compared facial nerve
function, occlusion, TMJ functions, and scar visibility. CT scans were used to assess condylar shape abnormalities and condylar
measurements preoperatively and 6 months postoperatively.
Results: the mean operative time was a statistically significant reduction in favor of the EAORIF group. Clinical assessment
parameters at 6 months were not significant between groups except for scar visibility which showed significant results in favor
of EAORIF ( P< 0.05 ). CT measurements revealed a non-significant difference between fractured and non-fractured sides
within groups as well as between groups.
Conclusion: EAORIF offers faster function regain, superior esthetics and reveals minimal risk of facial nerve injury when
compared to CORIF in the treatment of unilateral displaced condylar fractures.
