Furthermore, no difference was found between the open and closed treatment groups. Which is in accordance with the study of Throckmorton et al.,26 which concludes that surgical correction of unilateral condylar process fractures has relatively little effect on the more standard measures of masticatory function.
In a prospective cohort study, it was found that women of older age experienced a less favorable outcome, as observed by the MFIQ scores, after closed treatment of a mandibular condyle fracture.36 Furthermore, masticatory performance of healthy young subjects (24.0 ± 4.2 years) was, in a cross-sectional study, better than that of healthy elderly subjects (72.1 ± 7.5 years).1 These data confirm our findings that women experience a worse mandibular function outcome; however, we found that age did not appear to have a significant effect on masticatory performance.
