Objectives 1) Identify anatomic variations of the temporal bone in children with and without cochlear malformations who experienced an intra-operative cerebrospinal fluid (CSF) gusher at the time of cochlear implantation. 2) Compare the anatomic findings in the current study to those described in prior studies. Methods A retrospective case-controlled chart review was performed on patients undergoing cochlear implant surgery. Computerized tomography images were analyzed in a single-blind fashion for characteristics and measurements of both the right and left cochlea, internal auditory canal, cochlear aperture, facial nerve canal, vestibular aqueduct, cochlear aqueduct, oval window, round window, vestibule, mastoid, tegmen tympani and semi-circular canals. After verifying equal variances, data was statistically evaluated utilizing the paired 2-tailed t test with criterion for statistical significance set at p < 0.05. Results The average age at implantation for this series of children was 4 years old. 70% of patients had cochlear malformations. 25% of patients had an abnormal internal auditory canal (IAC) and 30% had a widened cochlear aperture. Most patients with an abnormal IAC had an abnormal cochlear aperture; however, some patients with a normal IAC also had an abnormal cochlear aperture. Correlations between the temporal bone anatomy and the incidence of CSF gushers will be discussed. Conclusions Specific characteristics of the temporal bone anatomy may lead to an increased incidence of CSF gusher in cochlear implant surgery. Computerized tomography of the temporal bone can assist in the surgeon in evaluation and planning for cochlear implantation.

Abstract Objective This paper describes the construction of portals for electrode placement during cochlear implantation and emphasises the utility of pre-operative temporal bone three-dimensional computed tomography. Methods Temporal bone three-dimensional computed tomography was used to plan portal creation for electrode insertion. Results Pre-operative temporal bone three-dimensional computed tomography can be used to determine the orientation of temporal bone structures, which is important for mastoidectomy, posterior tympanotomy and cochleostomy, and when using the round window approach. Conclusion It is essential to create appropriate portals (from the mastoid cortex to the cochlea) in a step-by-step manner, to ensure the safe insertion of electrodes into the scala tympani. Pre-operative three-dimensional temporal bone computed tomography is invaluable in this respect.

The complexities of the temporal bone and the critical inter-relationships among its key structures can be simplified with three-dimensional computer-assisted reconstruction. Knowledge of the topography of these structures and their mutual relationships in essential in any surgical approach to the temporal bone. Sixty sagittal histologic sections of a normal left temporal bone were examined. Each section, 30 μm in thickness, was optically enlarged. Segments representing the facial nerve, internal carotid artery, and inner ear structures from individual slides were traced and data were entered into a computer. A personal computer was used for data processing and analysis. Graphic software developed in our laboratory generated images with x-y-z coordinates that could be rotated In any plane. The high resolution of the computer graphics system, combined with the precision of histologic sections, permitted study of the critical three-dimensional anatomic relationships among essential intratemporal bone structures. The capability of reproducing individual and joint images of the intratemporal bone structures and viewing them from all surgical angles gives skull base and otologic surgeons Important topographic guidance. Accurate spatial measurements of temporal bone anatomy are now possible with the application of computer graphic technology.

AbstractObjective:We aimed to review the history of anatomical dissection, and to examine how modern educational techniques will change the way temporal bone dissection is taught to otolaryngology trainees.Method:Review of the literature using Medline, Embase and PubMed database searches.Results:Temporal bone anatomy has traditionally been taught using cadaveric specimens. However, resources such as three-dimensional reconstructed models and ‘virtual reality’ temporal bone simulators have a place in educating the otolaryngology trainee.Conclusion:We should encourage the use of fresh frozen cadaveric temporal bone specimens for future otologists. Artificial three-dimensional models and virtual reality temporal bone simulators can be used to educate junior trainees, thus conserving the scarce resource of cadaveric bones.

Increasing concern with medicolegal issues has heightened the need for surgical simulation in training. Familiarity with the surgical anatomy of the temporal bone is essential for effective and safe otological surgery. Refinement of surgical technique and intimate knowledge of temporal bone anatomy can be gained by accurate dissection. The products of such endeavours are both illustrative and instructive. The issues, methods and techniques necessary for display of anatomical dissections are discussed.
