Summary
Extra-oral implants placed during tumor ablation surgery show a higher survival rate than those placed after. This finding emphasizes the benefit of immediate implant placement for maxillofacial reconstruction.
Area of Science:
- Oral and Maxillofacial Surgery
- Oncology
- Biomaterials
Background:
- Extra-oral implants are crucial for reconstructing maxillofacial defects after cancer surgery.
- Optimal timing for implant placement requires further investigation.
Purpose of the Study:
- To compare the survival rates of extra-oral implants placed during ablation (DA-implants) versus after ablation (AA-implants).
- To determine the impact of surgical timing on implant success in maxillofacial reconstruction.
Main Methods:
- Retrospective analysis of 103 extra-oral implants (44 nasal, 59 orbital) in 35 patients.
- Implant survival was assessed over a mean follow-up of 35 months (range 8-156 months).
- Comparison of survival rates between DA-implants and AA-implants in nasal and orbital regions.
Main Results:
- DA-implants demonstrated higher survival rates: 90.0% (orbital) and 93.5% (nasal).
- AA-implants showed lower survival rates: 82.8% (orbital) and 61.5% (nasal).
- A statistically significant higher survival rate was observed for DA-implants (p=0.044).
Conclusions:
- Extra-oral implants placed during ablative surgery have a significantly better survival rate.
- Immediate implant placement during tumor ablation is recommended for improved outcomes in maxillofacial reconstruction.
