Summary
Extra-oral implants offer a viable reconstructive option for craniofacial defects, particularly in cases of severe auricular deformities. This technique demonstrated good implant stability and minimal complications in two patients undergoing auricular epithesis reconstruction.
Area of Science:
- Reconstructive surgery
- Craniofacial reconstruction
- Auricular prosthetics
Background:
- Extra-oral implants are an alternative for craniofacial reconstruction in oncology.
- Severe auricular deformities, such as those from burns, necessitate advanced reconstructive methods.
Purpose of the Study:
- To evaluate the efficacy and safety of extra-oral implants for auricular epithesis reconstruction.
- To assess implant stability and soft tissue healing in patients with post-burn auricular defects.
Main Methods:
- Two female patients with post-burn auricular deformities underwent extra-oral implant placement for auricular epithesis.
- Implants were positioned in the auricle-temporal region, posterior and superior to the facial nerve emergency point.
Main Results:
- Good stability of fixtures, epithesis, and perimplant soft tissue was observed in most cases.
- A delay in soft tissue healing occurred in some patients; one implant was removed after 5 years due to cancer recurrence.
- No post-surgery complications like bleeding or infection were reported; no facial nerve lesions occurred.
Conclusions:
- Extra-oral implants are a safe and effective reconstructive technique for auricular defects.
- The procedure offers good aesthetic outcomes and implant stability with minimal surgical risks.

01:22Burn Injuries
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
