[Late results of frontal bone reconstructions using Paladon]

Area of Science:

• Neurosurgery
• Craniofacial Surgery
• Biomaterials Science

Context:

• Frontal bone defects result from radical frontal sinus operations (Riedel's operation) or traumatic bone fragment removal.
• Reconstruction of these defects is crucial for restoring facial contour and function.
• Acrylate prostheses offer a potential solution for large bone voids.

Purpose:

• To evaluate the efficacy and long-term outcomes of using acrylate prostheses (paladon-inlay) for reconstructing frontal bone defects.
• To describe the fabrication, sterilization, and surgical implantation of these custom prostheses.
• To assess the cosmetic and functional results in patients with frontal bone defects.

Summary:

• Twelve cases of frontal bone defects were treated with acrylate prostheses (paladon-inlay) 6-12 months post-operatively or post-injury.
• The study details the prosthesis production, sterilization, and implantation procedure.
• Patients were followed for up to 18 years, with most experiencing good cosmetic and functional results, and one case requiring removal due to infection.

Impact:

• Acrylate prostheses provide a reliable and durable solution for restoring facial profile and function after significant frontal bone loss.
• The study highlights the long-term success and patient satisfaction achievable with custom-fabricated implants in craniofacial reconstruction.
• This approach minimizes the need for complex reconstructive surgeries and improves quality of life for affected individuals.
