RESUMEN
Resumen La fractura aislada del mango del martillo es una entidad clínica poco habitual, pero frecuentemente subdiagnosticada. Lo fundamental es la sospecha clínica. El diagnóstico se confirma con la otoscopia neumática o la otomicroscopia con maniobra de Valsalva, en la cual se observa una movilidad anormal del mango del martillo. El rasgo de fractura se puede demostrar con tomografía computada de alta resolución o cone beam. Existen diferentes opciones de tratamiento como interposición de cartílago o uso de prótesis de reemplazo osicular así como cemento óseo. El cemento ionomérico vidrioso autocurado, muy utilizado en odontología, se ha usado en distintas cirugías otológicas con buenos resultados y biocompatibilidad. A nuestro saber no se ha usado en esta patología por lo que presentamos esta serie de tres casos en los cuales se ha usado esta novedosa técnica con buenos resultados clínicos.
ABSTRACT
Abstract Isolated fracture of the manubrium of the malleus is a rare clinical entity. Clinical suspicion is paramount. The usual clinical presentation is acute otalgia followed by tinnitus and fluctuating hearing loss after a brisk introduction and withdrawal of a finger into the external auditory canal. On physical examination, the eardrum looks normal on otoscopy. Only in pneumatic otoscopy or otomicroscopy with Valsalva an abnormal motility of the manubrium could bee seen. High-resolution computed tomography (CT) or cone beam CT is able to show the fracture line. Several treatment options have been proposed, such as interposition of bone or cartilage between the manubrium and the incus, total or partial ossicular replacement prosthesis; and the use of bone cement. Glass ionomer luting cement, with wide use in dentistry, has been used in several otological procedures with good biocompatibility and results, however, to our best knowledge, it has not been used to repair this type of fractures, so we present this novel material in three cases.
