Generierung der im Modell verwendeten Daten,Transmeatal labyrinthectomy can be a highly effective means of ablating vestibular function. One must be diligent in one’s search for neuroepithelium. If vestibular neuroepithelium is left behind, there is a high probability of failure. One must also take care not to injure the facial nerve during blind probing of the vestibule.

,Simulation der Feuerung und Gasströmung,Proper identification and management of the facial nerve has been throughly discussed in the sections on translabyrinthine, transcochlear, infratemporal fossa, and middle fossa surgery. A brief review of the basic anatomy of the facial nerve and philosophical considerations will follow.

Bernd Epple,Reinhard Leithner,Heimo WalterA discussion of oto-neurosurgical procedures would be incomplete without a brief discussion of potential complications. It is not the authors’ intent to describe in lengthy detail all aspects of oto-neurosurgical complications.

G-spot

Incisions for Oto-Neurological Surgery,Adequate exposure is essential for approaching the cerebellopontine (CP) angle, petrous apex, and clivus through the temporal bone. This begins with the skin incision which must be properly located to afford access to the mastoid cortex and lateral subocciput, or to the petrous apex.

CHECK

Postauricular Transmastoid Labyrinthectomy,Just as the complete simple mastoidectomy provides the first building block of temporal bone surgery, the transmastoid labyrinthectomy paves the way for many oto-neurosurgical approaches to the cerebellopontine (CP) angle. This procedure must be mastered prior to attempting to expose and open the internal auditory canal (IAC).

Translabyrinthine Removal of Acoustic Tumors,Having adequately exposed the contents of the IAC, a brief discussion regarding the technical aspects of acoustic tumor dissection is in order.

Retrosigmoid Surgery,Because it affords wider exposure to the posterior fossa and CP angle, the retrosigmoid approach is preferred for vascular decompression procedures on the V, VII, VIII, IX, X and XI cranial nerves.One must bear in mind that it requires more cerebellar retraction and hence has more inherent morbidity.
