Résumé
A total of 47 patients who underwent the craniofacial implantation of unsintered hydroxyapatite particles and a poly-L-lactide device were evaluated for clinical local findings and computed tomography (CT) images after about 6 months. Long-term follow-up of 3 patients was done from 5 to 11 years. The patients underwent CT imaging pre- and postoperatively, while local clinical examination was done upon follow-up. For the 3 patients who were followed up for more than 5 years, implant changes were evaluated by using CT. Computed tomography revealed 3 patients of dislocation, 2 patients of insufficient bone union, and 3 patients of implant breakage. All patients healed well with no complications requiring a secondary operation. The CT findings of the long-term cases revealed the following: a plate and screw were still present 5 years postsurgery (patient 1), mesh implants were completely resorbed after 9 years and 6 months (patient 2), and plates were almost resorbed after 11 years but some of their shapes remained (patient 3).The unsintered hydroxyapatite/poly-L-lactide device is useful in the maxillofacial region in terms of strength and radiographic contrast. However, since the absorption rate is slow, it is necessary to keep in mind its long-term radiographic detectability and the possibility of late-onset granuloma.
