Can antegonial notch angular measurements on lateral cephalometry be used to monitor children following TMJ ankylosis treatment?
Objective: This research aims to introduce using antegonial notch angular measurements on lateral cephalometry as a simple low-dose radiographic approach for monitoring mandibular growth in children after TMJA treatment.
Methods: This retrospective cohort study used dental records to identify eligible patients: healthy children with true unilateral TMJA who underwent conservative gap arthroplasty followed by post-operative physiotherapy. The primary outcome was changes in antegonial notch angular measurements over time. Secondary outcomes included correlations between antegonial notch angular measurements and two growth-related conventional cephalometric angles (SNB and ANB). We also explored the relationship between changes in antegonial notch angle over time and study covariates.
Results: Eleven patients aged 4 to 9.5 years with unilateral bony TMJA for periods ranging from 9 to 20 months who had undergone conservative gap arthroplasty followed by physiotherapy were included. Significant increases were observed in antegonial notch angles on both the affected and non-affected sides after treatment (p < .05), indicating resumed mandibular growth. Although the affected side remained significantly smaller than the non-affected side at both timepoints (p= 0.033 and 0.005), asymmetry did not change significantly over time (p= 0.273), suggesting parallel bilateral growth. Positive correlations were found between antegonial notch changes and SNB (p= 0.039-0.047). Multivariate regression indicated that TMJA duration significantly influenced changes in the affected-side notch angle (p= 0.004).
Conclusion: Based on these preliminary data, antegonial notch angular measurements on lateral cephalometric radiographs may offer a simple, reliable, and low-radiation alternative for monitoring mandibular growth in children after TMJA treatment. Further studies with larger sample sizes are required to support our findings.
期刊介绍：
CRANIO: The Journal of Craniomandibular & Sleep Practice is the oldest and largest journal in the world devoted to temporomandibular disorders, and now also includes articles on all aspects of sleep medicine. The Journal is multidisciplinary in its scope, with editorial board members from all areas of medicine and dentistry, including general dentists, oral surgeons, orthopaedists, radiologists, chiropractors, professors and behavioural scientists, physical therapists, acupuncturists, osteopathic and ear, nose and throat physicians.
CRANIO publishes commendable works from outstanding researchers and clinicians in their respective fields. The multidisciplinary format allows individuals practicing with a TMD emphasis to stay abreast of related disciplines, as each issue presents multiple topics from overlapping areas of interest.
CRANIO''s current readership (thousands) is comprised primarily of dentists; however, many physicians, physical therapists, chiropractors, osteopathic physicians and other related specialists subscribe and contribute to the Journal.
