A New Surgical Paradigm for Postnatal Repair of Open Neural Tube Defects Using Intraoperative Neurophysiology...

Area of Science:

• * Pediatric Surgery
• * Neuroscience
• * Developmental Biology

Background:

• * Open neural tube defects (ONTD) involve an exposed, unclosed neural plate, posing significant surgical challenges.
• * Conventional repair methods often prioritize preserving the entire neural placode, potentially leading to complications such as spinal cord tethering and inclusion dermoid cysts.
• * Impaired caudal neurulation in ONTD can result in defective conus medullaris and neurogenic bladder dysfunction, characterized by a spastic, high-pressure bladder and risk of kidney damage.

Purpose of the Study:

• * To present a new surgical technique for ONTD closure.
• * To minimize or eliminate three key complications associated with conventional ONTD repair: spinal cord tethering, inclusion dermoid cysts, and neurogenic bladder dysfunction.

Main Methods:

• * Description of a novel surgical approach for open neural tube defect closure.
• * Focus on techniques designed to avoid the pitfalls of traditional methods.

Main Results:

• * The proposed technique aims to reduce the incidence of spinal cord tethering by avoiding the over-stuffing of neural tissue.
• * It seeks to prevent the formation of inclusion dermoid cysts by carefully managing surrounding tissues.
• * The method is designed to mitigate neurogenic bladder complications by addressing caudal neurulation issues.

Conclusions:

• * The novel surgical technique offers a promising alternative for managing open neural tube defects.
• * It has the potential to significantly improve patient outcomes by reducing long-term morbidities.
• * Further clinical evaluation is warranted to confirm the efficacy and safety of this approach.
