Causes of Facial Asymmetry

Dental Causes

Loss of Deciduous Teeth
Congenitally missing tooth/teeth

Skeletal Causes

Mandible only
- Condylar Hyperplasia
- Condylar Hypoplasia
- Condylar Neoplasia
- Condylar Resorption
Maxilla only
Combination of both (Hemifacial Microsomia, Parry–Romberg syndrome)

Muscular Causes

Masseter Hypertrophy
Sternocleidomastoid fibrosis (Torticolis)

Functional Causes

Malpositioned tooth
Constricted maxillary arch

Traumatic Causes

Condylar Fracture

Evaluation

Evaluation of facial asymmetry can be done by diagnostic aids listed below. A radiograph such as panoramic x-ray can allow one to measure the length difference between the two ramus of the mandible. A PA Cephalogram allows one to understand the differences between bony structures on the left and the right side of the face. ^[1]

Extra-oral photographs
Lateral Cephalograms
Frontal Cephalograms
Cone-Beam Computed Tomography
Radioisotope imaging
Dental Casts
Panoramic Radiograph
Stereophotogrammetry
Laser scans

Characteristics

Mandibular asymmetry may present itself in 3 planes of space: Vertical, Transverse or Antero-posterior. It is important to note that these features maybe caused by either skeletal, dental or functional causes of asymmetries.^[2]^[3]

Lower dental midline deviation
Canted occlusal plane
- Due to increased mandibular ramus or condyle
- Increased supra-eruption of posterior teeth on the affected side
Unilateral Crossbite
Chin deviation
