| Abstract: | This study analysed the relationship between complaints and mandibular function after closed treatment of fractures of the mandibular condyle in a prospective study. In a 1-year follow-up, complaints were assessed during physical examination and function was assessed using the mandibular function impairment questionnaire (MFIQ), scoring range 0–68. Data from 114 patients (41 women, 73 men), mean age 28.1 years (SD 13.3), were available. On average the MFIQ scores were low 3.4 (SD 7.3). Ten patients (9%) experienced pain and 45 (39%) patients had a MFIQ score > 0. Mean mouth opening was 51.9 mm (SD 8.4). Occlusion was perceived as moderate or poor by 24% of the patients. In the logistic regression analysis mandibular function impairment (MFIQ score > 0) was entered as a dependent variable. Risk factors for mandibular function impairment were: pain, perceived occlusion (moderate or poor), absolute difference between left and right horizontal movements and age. A protective factor was mouth opening. The results of this study show that complaints (i.e. pain, perceived occlusion, reduced mouth opening, difference between left and right lateral movements and increased age) are predictors of mandibular function impairment after closed treatment of fractures of the mandibular condyle. |
