[Bone anchored auricular prosthesis for patients with grade III microtia]

Area of Science:

• Plastic Surgery
• Otolaryngology
• Biomedical Engineering

Background:

• Microtia, a congenital condition, often requires reconstructive surgery for both functional and esthetic restoration.
• Grade III microtia presents significant challenges in auricular reconstruction, impacting patient quality of life.
• Intraosseous implants offer a stable foundation for auricular prostheses, improving outcomes in complex cases.

Purpose of the Study:

• To evaluate the effectiveness of auricular prostheses supported by intraosseous implants in patients with Grade III microtia.
• To assess the esthetic results and rehabilitation process following this reconstructive approach.
• To determine the suitability of this method for patients with hemifacial microsomia.

Main Methods:

• Retrospective analysis of 7 patients (5 male, 2 female, aged 18-45) with Grade III microtia and hemifacial microsomia.
• Utilized reverse planning based on CT scans of hard and soft facial structures to determine implant number and position.
• Employed a minimally invasive surgical procedure with custom-manufactured surgical templates.

Main Results:

• Achieved good to excellent esthetic results in all patients.
• Demonstrated a short postoperative rehabilitation period.
• Highlighted the critical role of meticulous virtual planning and surgical template manufacturing for success.

Conclusions:

• Auricular prostheses on intraosseous implants provide a viable and effective solution for Grade III microtia reconstruction.
• The technique facilitates rapid medical and social rehabilitation for affected patients.
• Meticulous pre-operative planning is essential for optimal esthetic and functional outcomes.
