Cranial Nerve Injury at Birth

Overview

Cranial nerve injuries occur when the nerves in the head and neck are stretched or compressed during birth. This can happen due to strong pressure or twisting movements. These injuries can range from mild, temporary damage to more severe cases where the nerve is completely torn.

Common Nerve Injuries

  • Facial Nerve Injury: 
    • This can lead to weakness or paralysis on one side of the face. 
    • The baby’s face may look uneven when crying, with the mouth pulled to one side, deeper wrinkles on the normal side, and the affected side appearing smooth and swollen. 
    • In most cases, there are no visible signs of trauma on the face.
  • Vagus Nerve Injury: 
    • This nerve controls muscles in the throat and voice box. 
    • Injury here can cause issues with breathing or voice.

Causes

Sometimes, using forceps during delivery can cause facial nerve injuries, but often, these injuries are unrelated to delivery tools. Instead, they happen as the baby’s head passes through the mother’s pelvis.

Symptoms

Facial Asymmetry: When the baby cries, one side of the face may look different from the other. The mouth may droop, and the affected side may not wrinkle or move as it should.

Recovery and Management

Recovery:

  • Most babies start to recover within the first week, but full recovery can take several months. If the nerve damage is due to trauma, it often gets better on its own. If recovery doesn’t start within 7-10 days, a neurologist or surgeon should be consulted.

Eye Care:

  • The open eye may need protection with patches and artificial tears until the nerve heals.

Diaphragmatic Paralysis

What It Is:
Diaphragmatic paralysis occurs when the nerve that controls the diaphragm (the muscle that helps with breathing) is injured during birth. This can happen alone or along with other injuries like brachial plexus injury.

Symptoms:

  • Breathing Problems: The baby may have trouble breathing, with rapid breathing and low oxygen levels.
  • Delayed Symptoms: Initially, the breathing may improve with oxygen support, but the full extent of the injury may not be visible right away.

Diagnosis:

  • Imaging Tests: An ultrasound or X-ray may be used to see if the diaphragm is not moving properly.

Prognosis:

  • Unilateral (One Side) Injury: About 10-15% of babies with one-sided paralysis may not survive, but most recover within 6-12 months.
  • Bilateral (Both Sides) Injury: The prognosis is more serious, with about 50% of affected babies not surviving, and those who do may need long-term breathing support.

Management:

  • Monitoring: Careful monitoring of the baby’s breathing is crucial. Immediate medical intervention may be necessary if the baby has trouble breathing.
  • Bacterial Infections: 
    • If the infection is bacterial, antibiotics are the most common treatment. Antibiotic eye drops or ointments are typically prescribed, and in more severe cases, oral antibiotics may be necessary.
  • Viral Infections: 
    • Newborns suspected of having a herpes infection should be treated with acyclovir, a medication that helps prevent the infection from spreading throughout the body.
  • Chemical Irritation: 
    • If the conjunctivitis is due to chemical exposure from eye drops, no specific treatment is needed, but artificial tears can help relieve discomfort.
