ALASA, C. et al. Tolerancia al material de osteosíntesis en cirugía electiva del maxilar superior. Rev Esp Cirug Oral y Maxilofac [online]. 2003, vol.25, n.6, pp.347-350. ISSN 2173-9161.

In Europe, in the late seventies, Lurh, Spiessel, Schilli and Champy, among others developed and popularized internal fixation with plates and screws with the aim of avoiding the need of maxillomandibular fixation in the treatment of maxillofacial injuries and deformities. In this paper the need to remove this materials after the consolidation time is discussed. There are some adverse circumstances that oblige the surgeon to remove the hardware like, palpation, exposure, migration, locally infection or thermal intolerance. This paper presents a retrospective study of thirty-six patients who underwent Le Fort osteotomy at the Department of Oral and Maxillofacial Surgery in Vall d'Hebron Hospital. Also, a review of the complications derived from the hardware material is presented. After a minimum follow-up of 30 months the following results were observed: only 4 of the 160 installed miniplates had to be removed. The low incidence of complications does not justify the systematic removal of ostheosynthesis material in this group of patients.
