[Long-term stability with absorbable plates and internal fixation in orthognatic surgery]

Area of Science:

• Biomaterials Science
• Orthognathic Surgery
• Craniofacial Reconstruction

Context:

• Orthognathic surgery involves complex bone repositioning.
• Fixation of osteotomies and fractures requires robust yet resorbable materials.
• Self-reinforced polylactide (SR-PLLA) offers potential advantages in craniofacial applications.

Purpose:

• To evaluate the clinical efficacy and outcomes of using biodegradable SR-PLLA plates and screws.
• To describe the surgical technique for applying SR-PLLA fixation in various craniofacial procedures.
• To document the indications, complications, and long-term results associated with SR-PLLA use.

Summary:

• The study reports on the use of SR-PLLA plates and screws for fixation in 142 orthognathic surgery cases (maxillary osteotomies) and 208 total cases including fractures and craniodisostosis.
• Surgical methods, material characteristics, and clinical observations over an 8-year follow-up are presented.
• The author details the indications for SR-PLLA use and analyzes observed complications.

Impact:

• SR-PLLA provides a promising biodegradable alternative for skeletal fixation in craniofacial surgery.
• This approach may reduce the need for hardware removal and improve patient outcomes.
• Further research can optimize SR-PLLA applications in complex reconstructive procedures.
