13. Childhood Fractures And Diseases Of The Jaw And TMJ And Facial Traumatic Injuries As Factors Influencing Development Of Malocclusion

Question 1

13. Childhood Fractures/Diseases- Jaw, TMJ , Facial Traumatic Injuries

How childhood falls and impacts lead to malocclusion

Answer 1

• Result in fractures of jaws, including condylar neck
• Although fractures of condylar process tend to regenerate well=>
• Asymmetric growth of mandible may occur

Question 2

13. Childhood Fractures/Diseases- Jaw, TMJ , Facial Traumatic Injuries

Condylar fractures in relation to mandibular growth and malocclusion

Answer 2

• May heal quickly and often result in normal mandibular growth
• Asymmetric growth of mandible may occur if scarring restricts normal growth movements=>
• Malocclusion, especially if more scarring and restriction on one side

Question 3

13. Childhood Fractures/Diseases- Jaw, TMJ , Facial Traumatic Injuries

Why conservative management preferred for condylar fractures rather than surgical intervention

Answer 3

• Surgical intervention can worsen condition=>additional scarring
• Conservative management at time of injury and early mobilization of jaws help minimize restrictions on movement

Question 4

13. Childhood Fractures/Diseases- Jaw, TMJ , Facial Traumatic Injuries

Conditions besides condylar fractures that can lead to asymmetric fractures and malocclusion

Answer 4

• Temporomandibular joint (TMJ)=>Rheumatoid arthritis
• Congenital disorders=>Hemifacial microsomia
• Genetic syndromes=>Treacher Collins syndrome

Question 5

13. Childhood Fractures/Diseases- Jaw, TMJ , Facial Traumatic Injuries

Etiology and characteristics of hemifacial microsomia

Answer 5

• Congenital disorder affecting development of lower half of face, including=>
• Ears, mouth, and mandible
• Typically unilateral
• Results from vascular problems during fetal development
• Restricts developmental ability of affected area=>
• Malocclusion and facial asymmetry

Question 6

13. Childhood Fractures/Diseases- Jaw, TMJ , Facial Traumatic Injuries

Treacher Collins syndrome, and how it relates to malocclusion

Answer 6

• Genetic disorder characterized by deformities of=>
• Ears, eyes, cheekbones, and chin=>
• Malocclusion
• Management=>
• Reconstructive surgery, hearing aids, speech therapy
