Relevance and Recent Developments of Chitosan in Peripheral Nerve Surgery

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Neuroscience

Background:

• Chitosan, a chitin derivative, is a promising biomaterial for peripheral nerve reconstruction.
• It interacts favorably with neural cells and the microenvironment, promoting axonal regeneration and reducing neuroma formation.
• Chitosan offers safe biodegradation without toxic side effects.

Purpose of the Study:

• To review the physiological properties of chitosan.
• To evaluate chitosan's efficacy in peripheral nerve regeneration.
• To discuss the clinical translation of chitosan-based nerve repair strategies.

Main Methods:

• Literature review of experimental strategies for nerve repair using chitosan.
• Analysis of various chitosan-based biomaterial formats (nanofibers, hydrogels, nerve conduits).
• Examination of cell seeding concepts and preclinical/clinical translational studies.

Main Results:

• Chitosan biomaterials demonstrate potential in diverse nerve lesion models.
• Various chitosan architectures (e.g., hollow tubes, hybrid conduits) are being explored.
• Early clinical translation of hollow tube concepts shows promise.

Conclusions:

• Chitosan exhibits beneficial properties for peripheral nerve regeneration.
• Further conclusive analysis is required to establish its impact on patient recovery.
• Translational research and clinical evaluation are crucial for widespread adoption.
