Purpose
To investigate the efficacy and stability of temporomandibular joint disk repositioning
by suturing through an open incision in adolescents with anterior disk displacement
(ADD).
Methods
Patients (aged 10-18 years) diagnosed with ADD and operated for disc repositioning
between June 2019 and January 2021 were included in this study. Magnetic resonance
imaging (MRI) and cephalometric films before and 1 year after surgery were collected
from all patients. The surgical success rate was defined as the primary outcome variable.
Changes of condylar height, mandibular asymmetry, and retrognathia were defined as
the secondary outcome variables.
Results
One hundred and four patients (167 joints) with a mean age of 14.6 ± 1.81 years were
included in this study. Postoperative MRIs showed that all disks had been repositioned
with an overall success rate of 94%. Statistically significant differences were found
in the improvement of condylar height (P < .001), mandibular asymmetry (P < .001), and retrognathia (P < .001) after 1 year of follow-up. The relapse rate in patients <15 years (8.57%)
was higher than that of patients older than 15 years (4.12%), although this was not
statistically significant (P = .387).
Conclusions
For juvenile patients, disk repositioning by suturing through an open incision was
an effective treatment. Early surgery can promote condylar regeneration and alleviate
maxillofacial deformity in juvenile patients.
