Rehabilitation of auricular defect with implant-retained auricular prosthesis - A case report

Abstract

Rationale: Maxillofacial defect is of great concern physically, emotionally, and psychologically for a patient. However, it is an even bigger challenge for a team attempting rehabilitation, as a crucial decision has to be made between surgical approach and/or prosthetic rehabilitation. However, if both are combined, it will result in best of esthetics and function with ease of maintainance, resulting in a sucessful rehabilitation. This case report represents a case of auricular defect rehabilitated with a combination of implants and bar-retained silicone prosthesis. Patient Concern: A 38-year-old male patient with right auricular defect reported with the main concern of esthetic rehabilitation of a lost part of the external ear. Diagnosis: With through evaluation and examination, a diagnosis of acquired partial auricular defect of the right side secondary to trauma was established. Treatment: An implant-retained auricular prosthesis was planned for this case. Surgically, three intraoral implants were placed in the mastoid bone, and after healing, bar framework was fabricated and attached. Finally, silicone prosthesis was fabricated and delivered to the patient. Outcome: A successful rehabilitation was carried out in this case using implants and bar attachment for retention of the silicone prosthesis. This prosthesis provided excellent retention and restored the appearance and confidence of the patient. Take-away Lessons: Rehabilitation of the auricular defect can be carried out with surgical approach, which involves multiple surgeries, and still, the results may not be esthetically favorable. Prosthetic rehabilitation is an option, but retention is generally a hindrance. However, implant-retained prosthesis has really paved a way for rehabilitation of the maxillofacial defect esthetically and more reliably. Cone-beam computerized tomography (CT) can be used for planning and evaluation instead of CT, which will save the patient from a lot of radiation exposure. Hence, in the maxillofacial defect, attempts should be made to explore the option of implant-retained prosthesis.

Maxillofacial Surgery and Artificial Intelligence

“…[ 4 ] CAD/CAM can reduce the cost, time and complexity of the reconstruction process and improve the fit, function and aesthetics of the devices. [ 4 5 ] Bioprinters can even fabricate scaffolds to receive grafts and tissue engineering products. ML and DL can analyse various types of data such as images, texts, sounds and signals to assist in diagnosis, prognosis, treatment planning, outcome prediction and evaluation of maxillofacial surgery.…”
