Abstract
Introduction

To solve certain problems that arise in cochlear implant, sinus and skull base surgery, the use of bone cement (PolyBone®) has been introduced in our department. With the goal of making use of surgical bone cements, combining bone growth factors and polyphosphates has allowed the study of these biological materials.

Materials and results

We present a total of 28 patients aged between 2 and 69 years (mean age of 29.2 years) in whom PolyBone® has been used as an additional therapeutic tool in the ENT surgical area. Complications occurred in 2 patients (7.4%). One was minor, solved with conservative treatment; one was a major complication that required surgery to extract the material and remove the implant. In the other 26 patients (92.6%), excellent results were achieved.

Conclusions

Different autogenous and alloplastic materials are of great utility for fistula management, cavity filling or sinus obliteration, among other uses. The surgeon must understand their biological properties, fundamental characteristics, production technique and potential surgical applications to be able to prevent future complications. Among these materials, bone cement (PolyBone®) is an effective alternative that should be considered in surgical management of ENT pathology.

Resumen
Introducción

Para solucionar determinados problemas que nos surgen en la cirugía del implante coclear, de los senos paranasales y de la base de cráneo hemos introducido en nuestro servicio el uso de un cemento óseo (PolyBone®).

Con el objetivo de lograr la elaboración de cementos óseos de uso quirúrgico, la unión de factores de crecimiento óseo y polifosfatos ha permitido el estudio de estos materiales biológicos.

Material y resultados

Presentamos un total de 28 pacientes con edades comprendidas entre 2 y 69 años, y una edad media de 29,2 años en los que el PolyBone ® nos ha servido como un arma terapéutica más en el área quirúrgica de la ORL.

En dos de los pacientes (7,4%) aparecieron complicaciones. Una menor que solucionamos con tratamiento conservador y una complicación mayor, que requirió una cirugía de extracción del material y explantación del implante. En los otros 26 (92,6%) pacientes se obtuvieron excelentes resultados.

Conclusiones

Existen diferentes materiales autólogos y aloplásticos que nos sirven de gran utilidad para el manejo de fístulas, relleno de cavidades, u obliteración de senos entre otros. El cirujano debe conocer las propiedades biológicas, características fundamentales, técnica de obtención y posibles aplicaciones quirúrgicas para ser capaz de prevenir futuras complicaciones.

Entre estos materiales, el cemento óseo (PolyBone®) es una alternativa eficaz a tener en cuenta en el manejo quirúrgico de nuestra patología.
