Purpose: The aim of this study was to evaluate the success and survival rates of extraoral implants for the fixation of facial prostheses in three anatomical regions.
Materials And Methods: Subjects were consecutive patients with facial defects who underwent implant placement by the same surgeon in the orbital, nasal, and auricular regions between 2003 and 2012. After a minimum of 4 months of osseointegration, prostheses were anchored to the implants, and the patients were monitored for 11 to 111 months.
Purpose: The aim of the study was to compare the success rates of osseointegration among irradiated and nonirradiated cases submitted to implant placement for anchorage of orbit prostheses from 2003 to 2011.
Materials And Methods: Charts of 45 consecutive patients were analyzed, 31 men and 14 women, and they were divided in two groups, considering previous irradiation therapy. Nonirradiated group had 33 patients, and irradiated group had 12 patients.
Unlabelled: The aim of this study is to analyze the success of extraoral osseointegrated implants used to support designed to rehabilitate craniofacial deformities.
Method: This study was based on the retrospective assessment of charts from 59 patients submitted to cancer surgery and who received 164 extraoral implants to contain facial prosthesis.
Results: Among 164 implants, 42 were fixed in previously irradiated regions.
Background: Maxillofacial defects caused by cancer treatment are a huge problem affecting the quality of life of patients. Some of these deformities are minimized using facial epitheses, which need some additional retention devices like glasses or skin adhesives. The use of extraoral fixtures as bone anchorage was introduced many years ago and since then many patients were rehabilitated with better results.
