Summary

Extraoral osseointegrated implants are safe and effective for rehabilitating craniofacial deformities. Radiotherapy does not hinder implant osseointegration, ensuring successful prosthetic support.

Area of Science:

Oral and Maxillofacial Surgery
Biomaterials Engineering
Reconstructive Surgery

Background:

Craniofacial deformities pose significant challenges in patient rehabilitation.
Extraoral osseointegrated implants offer a viable solution for supporting facial prostheses.

Purpose of the Study:

To evaluate the success rate of extraoral osseointegrated implants in patients with craniofacial deformities.
To assess the impact of prior radiotherapy on implant osseointegration and success.

Main Methods:

Retrospective chart review of 59 patients.
Analysis of 164 extraoral implants used for facial prosthesis rehabilitation.
Inclusion of implants placed in both irradiated and non-irradiated bone regions.

Main Results:

Overall, 164 extraoral implants were analyzed.
116 out of 164 implants (95.1%) achieved successful osseointegration in non-irradiated sites.
40 out of 42 implants (95.3%) in previously irradiated regions also achieved successful osseointegration.

Conclusions:

Extraoral craniofacial implants are a safe and effective method for rehabilitating patients with facial deformities.
Radiotherapy treatment does not negatively impact the osseointegration of these implants.
Successful prosthetic rehabilitation is achievable even in patients with a history of radiation therapy.
