Burn Injuries

2.3K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Area of Science:

  • Plastic Surgery
  • Anesthesiology
  • Burn Reconstruction

Background:

  • Microstomia and contractures after orofacial and neck burns create difficult airway scenarios.
  • Challenges include fibrosed nares, limited mouth opening, and deformed facial structures impacting ventilation.
  • The "cannot intubate, cannot ventilate" situation is a critical concern in anesthesia for these patients.

Observation:

  • A case of severe microstomia with limited mouth opening (15 mm) post-burns was managed.
  • The patient required airway management and oral commissuroplasty for functional and aesthetic reconstruction.
  • Fiberoptic nasal intubation was employed due to the difficult airway.

Findings:

  • Bilateral oral commissuroplasty using the Dieffenbach technique was performed for microstomia release.
  • Successful reconstruction significantly increased mouth opening from 15 mm to 55 mm.
  • The procedure aimed for both functional improvement and acceptable aesthetic outcomes.

Implications:

  • This approach offers a viable solution for managing severe microstomia post-burns.
  • Effective airway management and surgical reconstruction are crucial for patient outcomes.
  • The Dieffenbach commissuroplasty technique demonstrated significant functional gains in mouth opening.
