Study Notes
Wound Healing Processes
- Secondary intention wound healing involves longer repair and healing time, greater chances of scarring, and increased chance of infections.
- Delayed primary intention wound healing creates more scar tissue.
- Primary intention wound healing occurs when tissue edges are closed by stitches, staples, or steri-strips, resulting in quick and easy wound healing.
Wound Healing Phases
- Debridement phase involves denuding the epithelial layer, potential involvement of nerve endings, and minor bleeding from capillaries.
- Proliferation phase involves the formation of new blood vessels, collagen deposition, and granulation tissue formation.
Wound Characteristics
- Abrasions are caused by friction or scraping forces.
- Wounds with lost tissue or gaping edges are characteristic of delayed primary intention wound healing.
Wound Management
- Gentle pressure is applied to control minor bleeding from capillaries.
- Orofacial region injuries involve specialties like oral surgery, orthodontics, and pediatrics.
- Contusions (bruises) caused by dentoalveolar trauma are managed by applying cold compresses and monitoring for hematoma.
- Superficial external burns are managed by applying topical antibiotics and non-adherent dressings.
- Deep structures like muscle and tendons are sutured with braided sutures.
- Tetanus vaccination status should be considered in soft tissue injuries.
- Surgical intervention is required for contusions (bruises) that involve significant hematoma or nerve damage.
- Debris from a deep laceration is removed using a scrub brush and antibacterial soap.
- Systemic antibiotics are considered in soft tissue injuries with signs of infection or in immunocompromised patients.
- Lacerations in the oral cavity that do not require closure with sutures are managed with antibacterial mouthwash and monitoring.
- Lip lacerations require careful repair to avoid an ugly step on healing.
- Facial skin sutures are removed postoperatively 4-7 days after surgery.
Burns and Injuries
- Full-thickness burns involve the entire dermis and may require skin grafting.
- Nerve injuries usually require surgical nerve repair or grafting.
Learn about the clinical, diagnostic, and management aspects of soft tissue injuries in the orofacial region. Understand the principles of managing soft-tissue injuries, and the process of wound healing involving inflammatory, proliferative, and remodeling stages.
