OBJECTIVE: Making a 3-dimensional (3D) temporal bone model is simple using a plaster powder bed and an inkjet printer. However, it is difficult to reproduce air-containing spaces and precise middle ear structures. The objective of this study was to overcome these problems and create a temporal bone model that would be useful both as a training tool and for preoperative simulation. METHODS: Drainage holes were made to remove excess materials from air-containing spaces, ossicle ligaments were manually changed to bony structures, and small and/or soft tissue structures were colored differently while designing the 3D models...

BACKGROUND: Aberrant internal carotid artery (aICA) is an anatomical anomaly whereby the internal carotid artery (ICA) courses through the tympanic cavity without separation by bone. Since aICA is rare, there are no definite treatment strategies for aICA and its complications. CASE DESCRIPTION: We report a case of aICA accompanied by pseudoaneurysm formation and massive bleeding. Our case was a 31-year-old woman with a 2-year history of hearing loss, ear fullness, and pulsatile tinnitus in her left ear...

PURPOSE: This study tested the hypothesis that children with otitis media with effusion (OME) attending a primary school are at risk of impairment of their musical skills. OME is characterized as an inflammation with accumulation of secretion in the tympanic cavity, leading to conductive hearing loss. METHOD: Perception of music in children is assessed using the Montreal Battery of Evaluation of Music Abilities (MBEMA). Listeners are required to judge whether two successive melodies are the same or different on tests of scale, contour, interval and rhythm...

In cases of head trauma, the ear should be evaluated in all of its components. A good understanding of otologic and skull base anatomy enables a thorough trauma assessment of this complex anatomic region. Auricular laceration, abrasion, avulsion, hematoma, frostbite, otitis externa, exostosis, tympanic membrane perforation, ossicular discontinuity, perilymphatic fistula, labyrinthine concussion, temporal bone fracture, facial nerve paresis, and sensorineural hearing loss are a few of the more common otologic injuries seen in active patients...

INTRODUCTION: The middle ear ossicles form a semi rigid chain in the middle of the ear for conduction and amplification of sound waves from the tympanic membrane to the inner ear. Although, our knowledge of the ear ossicles dates back to the 15(th) century, and various studies have been carried out on their morphometry, morphology, anomalies, embryology, function and structure throughout the world, information about the morphology of middle ear ossicles is meagre in Indian subjects. AIM: To find out the morphological variations of middle ear ossicles of right and left sides...

The objective of the present study was to determine the optimal parameters of radiation of the CO2 laser during the surgical intervention for the treatment of the patients presenting with otosclerosis. The experimental part of the study was carried out with the use of the isolated temporal bones. Under the clinical conditions, the patients with the tympanic and mixed forms of otosclerosis underwent stapedoplasty with the use of the CO2 laser. It was shown that the use of the CO2 laser at different stages of stapedoplasty considerably reduces the risk of development of the post-operative complications...

Exudative otitis media is a widespread pathological condition in the human population. In the recent years, the treatment with the electric current having the frequency up to 3.8 MHz has found the increasingly frequent application, in addition to shunting and laser myringotomy, for the perforation of the tympanic membrane to facilitate removal of exudate. The objective of the present study was to evaluate the effectiveness of the application of the electric current with the frequency up to 4 MHz for myringotomy in the patients presenting with exudative otitis media under the experimental conditions and in the clinical practice...

Intracochlear schwannomas can occur either as an extension of a larger tumor from the internal auditory canal, or as a solitary labyrinthine tumor. They are currently removed via a translabyrinthine approach extended to the basal turn, adding a transotic approach for tumors lying beyond the basal turn. Facial bridge cochleostomy may be associated with the translabyrinthine approach to enable the whole cochlea to be approached without sacrificing the external auditory canal and tympanum. We describe seven cases, five of which underwent cochlear schwannoma resection with facial bridge cochleostomy, one case with the same procedure for a suspect tumor and one, previously subjected to radical tympanomastoidectomy, who underwent schwannoma resection via a transotic approach...

BACKGROUND: Hearing can be induced not only by airborne sounds (air conduction [AC]) and by the induction of skull vibrations by a bone vibrator (osseous bone conduction [BC]), but also by inducing vibrations of the soft tissues of the head, neck, and thorax. This hearing mode is called soft tissue conduction (STC) or nonosseous BC. PURPOSE: This study was designed to gain insight into the mechanism of STC auditory stimulation. RESEARCH DESIGN: Fluid was applied to the external auditory canal in normal participants and to the mastoidectomy common cavity in post-radical mastoidectomy patients...

An overview of the literature on the chondrocranium of marsupial mammals reveals a relative conservatism in shape and structures. We document the histological cranial anatomy of individuals representing Monodelphis domestica, Dromiciops gliroides, Perameles sp. and Macropus eugenii. The marsupial chondrocranium is generally characterized by the great breadth of the lamina basalis, absence of pila metoptica and large otic capsules. Its most anterior portion (cupula nasi anterior) is robust, and anterior to it there are well-developed tactile sensory structures, functionally important in the neonate...
