Conservative reduction by lever action of chronic bilateral mandibular condyle dislocation
Cranio : the Journal of Craniomandibular Practice
|April 29, 2015
Summary
Conservative lever action reduction successfully treated chronic temporomandibular joint dislocation in a patient after 3 years. This minimally invasive approach offers a viable alternative to surgery for long-standing joint dislocations.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Temporomandibular Joint Disorders
Background:
- Long-standing temporomandibular joint (TMJ) dislocation treatment typically involves open or closed reduction.
- Chronic bilateral mandibular condyle dislocation presents a significant clinical challenge.
Observation:
- A 31-year-old female patient with a 3-year history of TMJ dislocation underwent conservative reduction by lever action after manual repositioning failed.
- The patient declined general anesthesia, opting for a less invasive method.
Findings:
- Initial treatment was paused due to tooth subluxation, necessitating a switch from tooth-based to screw-based intermaxillary fixation.
- Reduction was achieved within 15 days of reinstituting treatment, with retention lasting 2 months.
- No recurrent dislocation was observed during a 24-month follow-up period.
Implications:
- Conservative reduction by lever action is a potentially effective, minimally invasive treatment option for chronic TMJ dislocation.
- This technique may reduce patient dysfunction and offer an alternative to surgical interventions.
- Further studies are warranted to establish the long-term efficacy and broader applicability of this conservative method.
