Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...
Pneumothorax-I01:26

Pneumothorax-I

A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
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 procedure...

Area of Science:

  • Veterinary Medicine
  • Comparative Pathology
  • Canine Traumatology

Background:

  • Head trauma in dogs can result in complex facial and neurological injuries.
  • Tympanic bulla fractures are rare, particularly those resulting from direct trauma.

Observation:

  • A Pekingese dog presented with significant head trauma, including facial swelling, puncture wounds, mandibular fractures, and ocular deficits.
  • Computed tomography revealed multiple fractures of the mandible and zygomatic arch, right ear canal avulsion, and a ventrally displaced tympanic bulla fracture.

Findings:

  • The tympanic bulla fracture and ear canal avulsion were managed conservatively with no short-term complications.
  • Surgical intervention included a subtotal hemimandibulectomy for mandibular fractures and placement of a temporary oesophagostomy feeding tube.
  • No complications were reported 18 months post-injury, suggesting conservative management can be effective for certain tympanic bulla fractures.

Implications:

  • This case represents the first reported instance of a traumatic tympanic bulla fracture in a dog.
  • The findings suggest that conservative management may be a viable option for specific types of traumatic tympanic bulla fractures in canine patients.
  • Highlights the importance of advanced imaging like CT in diagnosing complex head trauma in veterinary medicine.
