Diagnosing rare infant mandibular fractures requires high suspicion. A 3-month-old infant with a symphysis fracture healed well with circummandibular fixation and an acrylic splint, showing normal tooth development.
Area of Science:
- Pediatric surgery
- Oral and maxillofacial surgery
- Infant trauma management
Background:
- Mandibular fractures in infants are uncommon and challenging to diagnose due to subtle clinical signs and limited history.
- Early diagnosis necessitates a high index of suspicion and thorough caregiver history.
- Management options vary from conservative approaches to surgical fixation, each with potential impacts on growth and development.
Observation:
- This case study focuses on a 3-month-old male infant presenting with a mandibular symphysis fracture.
- The infant underwent surgical intervention involving fracture reduction and circummandibular fixation.
- Immobilization was achieved using an acrylic splint for a duration of 4 weeks.
Findings:
- The treatment successfully reduced the displaced mandibular fracture.
- Follow-up at 20 months revealed complete healing of the fracture site.
- The infant demonstrated adequate dentition development, indicating no adverse effects on tooth development.
Implications:
- Circummandibular fixation with an acrylic splint is a viable treatment for infant mandibular symphysis fractures.
- This approach allows for anatomical reduction and fixation while minimizing risks to mandibular growth and tooth development.
- Effective management can lead to favorable long-term outcomes, including proper healing and normal dentition.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
Structural Joints: Fibrous Joints
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
