3D Printing for the Development of Palatal Defect Prosthetics

Area of Science:

• Medical Devices
• Biotechnology
• Surgical Technology

Background:

• Three-dimensional (3D) printing is an emerging technology for surgical prosthetics, with demonstrated success in orthopedic surgery for improved implant precision and patient outcomes.
• Limited research exists on the application of customized 3D printed prosthetics within otolaryngology.
• This study investigated the feasibility of using computed tomography (CT) as templates for 3D printed palatal obturator prosthetics in patients with head and neck cancer defects.

Purpose of the Study:

• To determine if CT scans are feasible templates for constructing 3D printed palatal obturator prosthetics.
• To explore the potential of 3D printing for patient-specific implants in otolaryngology.

Main Methods:

• A retrospective review identified one patient with palatal defects and high-quality CT scans suitable for 3D modeling.
• CT data of the patient's craniofacial anatomy was used to develop a 3D model.
• A Formlabs 3B+ printer was utilized to print the custom palatal prosthetic.

Main Results:

• An individualized palatal prosthetic was successfully developed and produced using CT scans of a veteran with head and neck deformities.
• The project demonstrated the capability of printing patient-specific implants from CT-derived models of craniofacial anatomy, specifically the palate.
• This was a proof-of-concept study; the created implant was not used in the patient.

Conclusions:

• Customized 3D printed implants hold potential for otolaryngologists to improve surgical performance and efficiency.
• These patient-specific prosthetics can aid in the rehabilitation and reconstruction of craniofacial deformities, restoring both appearance and function.
• Future research aims to enhance the therapeutic value of these prosthetics, focusing on low-cost, patient-specific solutions.
