Early microsurgical reconstruction in birth palsy

Area of Science:

• Neurology
• Pediatric Surgery
• Neurosurgery

Background:

• Birth palsy often results in unsatisfactory functional recovery.
• Early surgical nerve reconstruction is a potential method to improve outcomes.
• Identifying appropriate candidates for surgery is crucial.

Observation:

• Six infants with birth palsy and no recovery signs underwent brachial plexus exploration.
• Preoperative imaging (metrizamide myelography, CT myelography) and histamine testing were performed.
• Intraoperative electrophysiologic tests (SEP, NAP, M-response) guided microsurgical repair.

Findings:

• Metrizamide myelography had a 13% false-positive rate for root avulsion.
• The histamine test demonstrated 80% reliability.
• Intraoperative electrodiagnosis proved essential for accurate brachial plexus lesion assessment.

Implications:

• Microsurgical nerve repair based on intraoperative diagnosis yielded encouraging results.
• This diagnostic and therapeutic program warrants further investigation.
• The long-term superiority of surgical intervention over natural recovery requires clarification.
