Page 130 - Open versus closed Mandibular condyle fractures

There were no strict indications for either treatment; the choice was principally based on the preference of the surgeon. In both groups, if rehabilitation was delayed or patients had persistent complaints after 6 weeks, active physiotherapy was started. Follow-ups after the first contact were scheduled at 5 to 7 days, and at 3, 6, and 12 weeks. If the patient had recovered well, follow-up was ended. If symptoms, such as an open bite, limited mouth opening or pain, persisted, follow- up was extended to 6 months or even 1 year. In cases of severe malocclusion, uncontrolled pain, or poor patient compliance, open treatment was considered.
STATISTICS
The patient population was described using percentages, means, and standard deviations (SDs) for continuous data. The normality of the continuous data was assessed using the Kolmogorov-Smirnov test. The independent t-test (continuous data), the chi-squared test (categorical data), and the Mann-Whitney U test (ordinal data or not normally distributed continuous data) were used to determine whether there was a significant difference between the two treatment modalities and included and excluded patients. The Spearman test was used to assess the correlation between the MAI and MFIQ.
Linear regression was used to explore the effects of gender, age, education level, cause of trauma, fracture type, presence of other fractures, physiotherapy, duration of follow-up, MMO, dental status, self-perceived occlusion, and treatment modality, on the MAI. Backward elimination in stepwise regression was used to create a definitive model. The data were analysed using SPSS version 24 (IBM Corporation, Armonk, NY, USA), and P < 0.05 was considered to be statistically significant.
RESULTS
In total, 58 patients with a unilateral fracture were included, i.e., 33.9% of the 171 patients (unilateral and bilateral fractures) who were approached. The included and excluded patients with a unilateral condyle fracture did not differ significantly in age (P = 0.205), gender (P = 0.574), fracture level related to the mandibular joint capsule (intracapsular and extracapsular) (P = 0.769), site of the fracture (P = 0.165), other fractures (P = 0.618), and open and closed treatment (P= 0.060).
