Introducción: Esta revisión hace énfasis en la luxación incudomaleolar. Aunque poco frecuente, es una patología con gran relevancia clínica debido a la afectación de la audición a corto y mediano plazo en los pacientes, afectando así su calidad de vida, por lo que es necesario un diagnóstico oportuno para un tratamiento temprano y eficaz. Objetivo: describir los hallazgos imagenológicos e identificar los diferentes mecanismos etiológicos de la luxación incudomaleolar. Metodología: Se realizó una revisión bibliográfica en PubMed de los artículos publicados hasta febrero de 2015 con las palabras claves: “Ear ossicles”; “Temporal bone”; “Bone”; “Fractures”; “Dislocation”; “Conductive hearing loss”. Se encontraron 352 artículos de los cuales se seleccionaron aquellos donde se menciona la luxación incudomaleolar. Resultados: Se revisaron los abstracts de los 352 artículos, encontrando 20 donde mencionaban la definición, la epidemiología, la clínica y el diagnóstico imagenológico de la luxación incudomaleolar, los cuales fueron utilizados para la elaboración de esta revisión. Conclusiones: La principal causa de daño en la cadena de huesecillos es la fractura del hueso temporal y dentro de las patologías que puede generar está la luxación incudomaleolar, por lo que es de interés el diagnóstico temprano a todos los pacientes con sospecha clínica para llegar a prevenir complicaciones. La revisión de la literatura permite concluir que la técnica más eficaz para la identificación de la luxación Incudomaleolar es la tomografía computarizada, la cual requiere una adecuada identificación en los diferentes cortes multiplanares, o en las reconstrucciones 3D para poder diagnosticarla.

Objectives To assess the feasibility of radiologic measurements and find out whether hearing outcome could be predicted based on computer tomography (CT) scan evaluation in patients with temporal bone fractures and suspected ossicular joint dislocation. Methods We assessed 4002 temporal bone CT scans and identified 34 patients with reported ossicular joint dislocation due to trauma. We excluded those with no proven traumatic ossicular dislocation in CT scan and patients with bilateral temporal bone fractures. We measured four parameters such as malleus-incus axis distance, malleus-incus angle at midpoints, malleus- incus axis angle and ossicular joint space. The contralateral healthy side served as its own control. Hearing outcome 1–3 months after the index visit was analyzed. We assessed diagnostic accuracy and performed a logistic regression using radiologic measurement parameters for outcome prediction of conductive hearing loss (defined as >20dB air-bone gap). Results We found excellent inter-rater agreement on the measurement of axis deviation between incus and malleus in CT scans (interclass correlation coefficient 0.81). The larger the deviation of incus and malleus axis, the higher probability of poor hearing outcome (odds ratio (OR) 2.67 per 0.1mm, p = .006). A cut-off value for the axis deviation of 0.25mm showed a sensitivity of 0.778 and a specificity of 0.94 (p < .001) for discrimination between poor and good hearing outcome in terms of conductive hearing loss. Conclusion Adequate assessment of high resolution CT scans of temporal bone in which ossicular chain dislocation had occurred after trauma was feasible. Axis deviations of the incus and the malleus were strongly predictive for poor hearing outcome in terms of air conduction 1–3 months after trauma. We propose a 3-level classification system for hearing outcome prediction based on radiologic measures.

The aim of this article is to determine hearing and mortality outcomes following temporal bone fractures. Retrospective chart review was performed of 152 patients diagnosed with a temporal bone fracture presenting to the emergency room at a tertiary care referral center over a 10-year period. Utilizing Patients’ previously obtained temporal bone computed tomographic scans and audiograms, fractures were classified based on several classification schemes. Correlations between fracture patterns, mortality, and hearing outcomes were analyzed using χ2 tests. Ossicular chain disruption was seen in 11.8% of patients, and otic capsule violation was seen in 5.9%; 22.7% of patients presented for audiologic follow-up. Seventeen patients with conductive hearing loss had air–bone gaps of 26 ± 7.5 dB (500 Hz), 27 ± 6.8 dB (1,000 Hz), 18 ± 6.2 dB (2,000 Hz), and 32 ± 7.7 dB (4,000 Hz). Two cases of profound sensorineural hearing loss were associated with otic capsule violation. No fracture classification scheme was predictive of hearing loss, although longitudinal fractures were statistically associated with ossicular chain disruption ( p < 0.01). Temporal bone fractures in patients older than 60 years carried a relative risk of death of 3.15 compared with those younger than 60 years. The average magnitude of conductive hearing loss resulting from temporal bone fracture ranged from 18 to 32 dB in this cohort. Classification of fracture type was not predictive of hearing loss, despite the statistical association between ossicular chain disruption and longitudinal fractures. This finding may be due to the low follow-up rates of this patient population. Physicians should make a concerted effort to ensure that audiological monitoring is executed to prevent and manage long-term hearing impairment.

Otic capsule dehiscences create a pathological third window in the inner ear that results in a dissipation of the acoustic energy consequent to the lowered impedance. Superior semicircular canal dehiscence (SSCD) was identified by Minor et al in 1998 as a syndrome leading to vertigo and inner ear conductive hearing loss. The authors also reported the relation between the dehiscence and pressure- or sound-induced vertigo (Tullio’s phenomenon). Prevalence rates of SSCD in anatomical studies range from 0.4% to 0.7% with a majority of patients being asymptomatic. The observed association with other temporal bone dehiscences, as well as the propensity toward a bilateral or contralateral “near dehiscence,” raises the question of whether a specific local bone demineralization or systemic mechanisms could be considered. The present report regard a case of a patient with a previous episode of meningitis, with a concomitant bilateral SSCD and tegmen tympani dehiscence from the side of meningitis. The patient was affected by dizziness, left moderate conductive hearing loss, and pressure/sound-induced vertigo. Because of disabling vestibular symptoms, the patient underwent surgical treatment. A middle cranial fossa approach allowed to reach both dehiscences on the symptomatic side, where bone wax and fascia were used for repair. At 6 months from the procedure, hearing was preserved, and the vestibular symptoms disappeared.

Conductive Hearing

A 15-year-old patient had unilateral double congenital cholesteatomas, one isolated to the mastoid and the other located in the petrous pyramid. The presenting symptoms were facial palsy and a conductive hearing loss on the affected side. The case is interesting, not only in that there were two isolated cholesteatomas in the same temporal bone, but also because of the combination of ossicular anomalies. The unusually early detection and surgical intervention in this instance suggest that similar cases of multicentric cholesteatomas may have occurred, but may have been concealed because of the later detection and possible linkage of the cholesteatomas. I would therefore emphasize Sheehy's recommendation that temporal bone radiography never be omitted where idiopathic facial nerve palsy exists.

The temporal bone report of an operated case of osteogenesis imperfecta tarda is presented. Histological examination confirmed the presence of bilateral fixation of the footplate by otosclerosis as the cause of the conductive hearing loss. Fragility of bony septae in the mastoid and of the stapedial crura were observed. Sensorineural impairment in later years with a reduction in neural elements in the cochlea appear related to the extent and activity of the otosclerotic foci. Additional temporal bone reports of three cases of osteogenesis imperfecta congenita show lack of deposition of the skein-like bone in the endochondral layer, sparse bony septae in marrow spaces and deficiency of the periosteal layer. The stapedial crura were thin and in two cases both were deformed and fractured.

AbstractObjectives:To demonstrate the need for computed tomography imaging of the temporal bone before considering revision stapes surgery in patients with recurrent or residual conductive hearing loss.Case report:We report the case of a high-riding jugular bulb with an associated jugular bulb diverticulum, which was dehiscent towards the vestibular aqueduct, in a patient with confirmed otosclerosis who did not experience hearing improvement after stapedotomy.Conclusion:This case demonstrates the usefulness of temporal bone computed tomography in the evaluation of patients with otosclerosis in whom stapedotomy has not improved hearing. In such patients, revision surgery to address residual hearing loss would eventually prove unnecessary and avoidable.

The case of a five year old boy who presented with a lower motor neurone facial nerve palsy secondary to primary non-Hodgkin’s lymphoma (NHL) of the middle ear is discussed. Any child who presents with a facial nerve palsy and conductive hearing loss requires thorough evaluation to exclude the possibility of temporal bone malignancy.
