    Study Notes

    Intermaxillary Fixation

    • Intermaxillary fixation is a common method used to treat jaw fractures.
    • The method involves fixing the upper and lower jaws together.
    • Multiple-loop wiring was a popular method during World War II.
    • The decision to remove a tooth in the line of fracture is based on factors such as presence of caries, periodontal disease, and esthetics.
    • Extraction of a tooth may be necessary if severe doubt exists about its viability.
    • Infected and carious teeth outside the fracture line should be extracted before intermaxillary fixation.
    • Elastic traction can be used to overcome distraction and muscle spasm.
    • Intermaxillary wires can be used after 1 week to better manage hygiene and patient comfort.
    • Antibiotics are often used as a prophylactic measure for the first week.
    • Hospitalization is generally recommended for fractured jaw patients.

    Condylar Fracture

    • The condylar neck is a common site for fractures.
    • The lateral pterygoid muscle attachment should be removed to prevent redislocation.
    • The condylar fracture treatment involves open reduction with direct wiring.
    • Telescoping of fragments can be addressed using figure-of-eight wiring or plate fixation.
    • Removal of the lateral pterygoid muscle attachment helps prevent dislocation.
    • Condylar fractures in children can impact jaw growth.
    • The most critical period for condylar fractures is from 1 to 5 years of age.
    • Reconstructed rami following closed treatment of condylar fractures occur in accordance with Wolff's law.
    • Fracture-dislocation in children less than 2.5 years old poses a particularly challenging situation.

    Fractured Jaws in Children

    • Deciduous teeth present challenges for wiring due to their bell-shaped form.
    • Acrylic splints are an alternative to wiring for deciduous teeth, although they require fabrication time.
    • Fine wires (28-gauge) facilitate wiring of deciduous teeth.
    • Malpositioned angle fractures in children are treated by open reduction.
    • Condyle fractures in children are usually treated conservatively.

    Feeding Problems

    • A high-protein, high-calorie, and high-vitamin diet is essential for patients with fractured jaws.
    • Liquid or semi-liquid foods are preferred.
    • Examples of suitable foods include:
      • Fruit juices
      • Cereals (thinned with milk)
      • Strained fruits
      • Strained meat
      • Strained vegetables
      • Cream soup

    Maxillary Fractures

    • Maxillary fractures are serious injuries due to the proximity of vital structures.
    • Common causes include automobile accidents, blows, industrial accidents, and falls.
    • The type and extent of the fracture are determined by the force, direction, and location of the impact.
    • Horizontal maxillary fractures (Le Fort I) involve separation of the maxilla from the skull above the palate and below the zygomatic process.
    • Horizontal fractures can result in a "floating jaw."
    • Displacement of the maxillary fracture can occur due to muscular pull or the force of impact.
    • The diagnosis can be missed if the fracture is not displaced.
    • Assessment involves examining the teeth, lips, and cheeks for signs of trauma.
    • Movement in the fractured jaw can be detected by applying pressure to the teeth.
