Middle Ear Virtual Endoscopy in Malleus Fracture and Dislocation

Abstract

Ossicular injury is a frequent complication of head trauma and temporal bone fractures. An isolated fracture of the malleus with lateral dislocation of the manubrium is extremely rare. High-resolution computed tomography is the method of choice for evaluation of ossicular trauma. Virtual endoscopy (VE) is a novel technique that provides a realistic surface rendering of various organs that can be applied for the use of three-dimensional (3D) reconstruction. We report a case of malleus handle fracture and dislocation after head trauma with confirmation of the diagnosis by VE of the middle ear.

Effect of temporomandibular joint bony ankylosis and surgical sequelae of gap arthroplasty on middle ear volume

“…Recently, virtual endoscopy and three-dimensional reconstructions of the middle ear as well as the tympanic cavity were used to assess middle ear pathologies and ossicular injuries using the standard high-resolution CT temporal bone as a template [27,28]. Axial high-resolution CT scans can ordinarily show the exact nature and placement of the ossicular fractures and dislocations.…”
