A novel design for prosthetic ear guiding device: A technical note

Area of Science:

• Medical Devices
• Biomedical Engineering
• Prosthodontics

Background:

• Achieving precise positioning for auricular implants and prostheses is crucial for aesthetic outcomes.
• Current methods may lack cost-effectiveness or integration capabilities for optimal planning.
• Patient satisfaction is highly dependent on the esthetic quality of ear prostheses.

Purpose of the Study:

• To introduce a novel Prosthetic Auricular Guide (PAG) for accurate planning and positioning of auricular implants and prostheses.
• To present a cost-effective guiding device that prioritizes esthetic results in ear reconstruction.
• To detail the PAG's utility in integrating clinical positioning with bone structures for precise implant placement.

Main Methods:

• Design and development of the Prosthetic Auricular Guide (PAG).
• Integration of the PAG with Cone-Beam Computed Tomography (CBCT) for planning.
• Surgical application of the fixed and adjustable PAG for position transmission.

Main Results:

• The PAG facilitates accurate planning and positioning of auricular implants and prosthetic auricles.
• The device enables integration with remaining bone structures using CBCT for precise implant planning.
• The adjustable nature of the PAG makes it suitable for diverse auricular defects, ages, and facial asymmetries.

Conclusions:

• The newly designed Prosthetic Auricular Guide (PAG) offers a cost-effective solution for improved esthetic ear prostheses.
• The PAG enhances surgical accuracy through integrated planning and intraoperative positioning.
• Its adaptability ensures suitability across a wide range of patient needs and defect types.
