Summary
Arthrogryposis multiplex congenita can affect the face, causing asymmetry and limited jaw movement. Conservative orthognathodontic treatment is recommended for this rare condition due to muscle damage.
Area of Science:
- Medical Case Reports
- Orthodontics
- Genetics
Background:
- Arthrogryposis multiplex congenita (AMC) is a rare disorder primarily affecting lower limbs with joint deformities.
- AMC can present with heterogeneous manifestations, including maxillofacial involvement.
Purpose of the Study:
- To report a case of AMC with significant maxillofacial and masticatory muscle involvement.
- To discuss diagnostic and therapeutic strategies for AMC affecting the stomatognathic system.
Main Methods:
- Clinical evaluation of a 20-year-old patient with AMC, skeletal crossbite, and facial asymmetry.
- Utilized advanced imaging (CT, MRI) and functional assessments (EMG, axiography) for diagnosis.
- Conservative orthognathodontic treatment with function generating bite and exercises was proposed.
Main Results:
- Diagnosed unilateral left mandibular hypoplasia, masticatory muscle hypotrophy, and condylar immobility.
- Identified reduced electromyography activity and fatty infiltration in left masticatory muscles.
- Confirmed skeletal asymmetry and limited mandibular movement.
Conclusions:
- AMC with maxillofacial involvement necessitates a patient-centered, multidisciplinary approach.
- Conservative orthognathodontic therapy is a suitable option for AMC patients with masticatory muscle damage.
