Early condylectomy to prevent prognathism: a preliminary report
Journal of Oral Surgery (American Dental Association : 1965)
|August 1, 1976
Summary
Bilateral condylectomy in children with prognathism interrupts mandibular growth, reducing protrusion. However, condyle reformation can lead to renewed growth, with no significant impact on jaw movement.
Area of Science:
- Orthodontics and Maxillofacial Surgery
- Pediatric Dentistry
Background:
- Prognathism in children presents significant challenges for facial growth and aesthetics.
- Surgical interventions are considered for severe cases to correct mandibular excess.
Purpose of the Study:
- To evaluate the efficacy of bilateral condylectomy in managing childhood prognathism.
- To assess the impact on mandibular anteroposterior growth and potential for condyle reformation.
Main Methods:
- Cephalometric radiographs were used to measure mandibular growth before and after surgery.
- Clinical observation assessed changes in mandibular position and function.
Main Results:
- Bilateral condylectomy effectively reduced prognathism by interrupting mandibular growth and causing immediate retropositioning.
- No clinically significant changes in mandibular movements were observed.
- Condyle reformation was noted, suggesting potential for future growth.
Conclusions:
- Bilateral condylectomy is a viable method for reducing prognathism in children.
- The procedure temporarily halts mandibular growth, but condyle reformation may lead to growth recommencement.
- Further monitoring is needed to understand long-term outcomes regarding condyle regeneration and growth patterns.
