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.

The junction of the petrosal and squamosal portions of the temporal bone has important relationships that are of interest to the otologist. The resultant suture extends from the glaserian fissure across the top of the middle ear cleft and into the mastoid portion of the temporal bone. It may permit quick passage of infection from the middle ear to the middle cranial fossa. The petrosa may override the squama, forcing it down into the tympanum, where it could cause malleus fixation and a conductive type hearing loss. In the mastoid the suture is identifiable on the surface, but in the interior it is represented by the petrosquamosal lamina. The deeper portion in the petrosal portion of the mastoid may be easily overlooked in surgery of the mastoid and may lead to facial nerve injury.

Hearing loss must be divided into conductive hearing loss (CHL) and sensorineural hearing loss (SNHL). CHL is caused by sound not reaching the cochlear (abnormality of the ear canal, tympanic membrane, middle ear, or ossicles), whereas SNHL is a condition affecting the cochlear or auditory (eighth cranial) nerve. Hearing loss may be accompanied by other cardinal signs of ear disease, such as pain or discharge from the ear, vertigo, facial nerve palsy, and tinnitus, which guide the diagnosis. This chapter describes the approach to the patient with hearing loss.

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.

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.

A rare facial nerve anomaly was incidentally discovered whilst performing a tympanoplasty and ossicular reconstruction on a patient with an acquired unilateral conductive hearing loss. The nerve was seen to bifurcate and straddle a normal stapes superstructure as it ran posteriorly through the middle ear, a unique and as yet unreported combination. This case highlights the importance of vigilance regarding facial nerve anatomical variations encountered during middle-ear surgery thus avoiding inadvertent damage. The purported embryological mechanism responsible for such anomalies of the intra-tympanic facial nerve is discussed.

Salivary gland choristoma is an extremely rare middle ear pathology. We present the case of a 10-year-old girl with unilateral conductive hearing loss. Tympanotomy showed a nonspecific middle ear mass, absence of stapes, anomaly of incus, and displaced facial nerve. It was not possible to remove the mass completely. Histology confirmed salivary gland choristoma. The hearing in this case can be improved with a bone-anchored hearing aid.
