“…High-resolution CT imaging is useful in the preoperative work-up, but may fail to describe the exact ossicular abnormality. In a large radiological series of 166 cases by Meriot et al [12] , incudomallear joint separation was observed as the most common posttraumatic abnormality. However, the prevalence of incudostapedial joint dissociation is radiographically underestimated because a hemotympanum often masks an interruption, especially when the ossicular ends are still aligned in their normal position.…”

“…This le-234 J Int Adv Otol 2016; 12(3): 231-6 sion was bridged with hydroxyapatite cement as illustrated in Figure 3. Meriot et al [12] reported among ossicular injuries a prevalence of 4% incus fractures, almost all affecting the long or lenticular process. Compared to the incus, the stapes is more securely anchored to the middle ear by its annular ligament and stapedial tendon and muscle.…”

“…Ossicular dislocations are far more common than fractures. They may occur in any of the ossicular joints and can be subdivided into incudostapedial joint or incudomallear joint separations, and dislocations of the incus, stapes or incudomallear complex [12] . Dislocations may range from a slight subluxation to a complete disruption of the joint.…”

OBJECTIVE:The purpose of this study was to investigate etiological, clinical, and pathological characteristics of traumatic injuries of the middle ear ossicular chain and to evaluate hearing outcome after surgery. MATERIAL AND METHODS:Thirty consecutive patients (31 ears) with traumatic ossicular injuries operated on between 2004 and 2015 in two tertiary referral otologic centers were retrospectively analyzed. Traumatic events, clinical features, ossicular lesions, treatment procedures, and audiometric results were evaluated. Air conduction (AC), bone conduction (BC), and air-bone gap (ABG) were analyzed preoperatively and postoperatively. Amsterdam Hearing Evaluation Plots (AHEPs) were used to visualize the individual hearing results. RESULTS:The mean age at the moment of trauma was 27.9±17.1 years (range, 2-75 years) and the mean age at surgery was 33.2±16.3 years (range, 5-75 years). In 10 cases (32.3%), the injury occurred by a fall on the head and in 9 (29.0%) by a traffic accident. Isolated luxation of the incus was observed in 8 cases (25.8%). Dislocation of the stapes footplate was seen in 4 cases (12.9%). The postoperative ABG closure to within 10 and 20 dB was 30% and 76.7%, respectively. CONCLUSION:Ossicular chain injury by direct or indirect trauma can provoke hearing loss, tinnitus, and vertigo. As injuries are heterogeneous, they require a tailored surgical approach. In this study, the overall hearing outcome after surgical repair was favorable.

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.

“…Disruption of the incus is the etiology for persistent posttraumatic conductive hearing loss [1][2][3][4]. The malleus is well stabilized by the tympanic membrane, ligamentous attachments, the malleoincudal articulation, and the tensor tympani tendon.…”

Dislocation of the Incus into the External Auditory Canal after Mountain-Biking Accident

We report a rare case of incus dislocation to the external auditory canal after a mountain-biking accident. Otoscopy showed ossicular protrusion in the upper part of the left external auditory canal. CT indicated the disappearance of the incus, and an incus-like bone was found in the left external auditory canal. There was another bony and board-like structure in the attic. During the surgery, a square-shaped bony plate (1 × 1 cm) was found in the attic. It was determined that the bony plate had fallen from the tegmen of the attic. The fracture line in the posterosuperior auditory canal extending to the fossa incudis was identified. According to these findings, it was considered that the incus was pushed into the external auditory canal by the impact of skull injury through the fractured posterosuperior auditory canal, which opened widely enough for incus dislocation.
