Navigation-Assisted Orbital Trauma Reconstruction Using a Bioactive Osteoconductive/Bioresorbable u-HA/PLLA System.

Area of Science:

• Oral and Maxillofacial Surgery
• Biomaterials Science
• Medical Imaging and Navigation

Background:

• Orbital fractures with wall defects are common, requiring restoration of anatomy and orbital tissue.
• Current implant materials have varied advantages and disadvantages for orbital reconstruction.
• Ideal materials should be conformable, stable, radiopaque, bioactive, and osteoconductive/bioresorbable.

Purpose of the Study:

• To review navigation-assisted orbital trauma reconstruction.
• To highlight the use of a novel uncalcined and unsintered hydroxyapatite (u-HA) and poly-L-lactide (PLLA) composite system.
• To discuss the benefits of this bioactive, osteoconductive/bioresorbable material in complex orbital reconstructions.

Main Methods:

• Review of existing literature on orbital fracture repair and implant materials.
• Discussion of the properties and application of u-HA/PLLA composite sheets.
• Exploration of intraoperative navigation techniques in orbital surgery.

Main Results:

• Novel u-HA/PLLA composite sheets show potential as innovative implant materials for orbital reconstruction.
• Navigation-assisted surgery improves precision, accuracy, and minimal invasiveness in complex orbital trauma cases.
• The u-HA/PLLA system is bioactive, osteoconductive, and bioresorbable, meeting ideal implant criteria.

Conclusions:

• Navigation-assisted orbital reconstruction with u-HA/PLLA composite sheets offers a precise and effective approach for complex defects.
• This bioactive and bioresorbable system holds significant promise for restoring orbital anatomy and function.
• Further research and clinical application of this integrated approach are warranted.
