Abstract:

When two complex structures like cerebellum and pons build up anangle, the one formed is not simple like the ones formed by twointersecting lines in geometry, but one, difficult to understand even by thepeople who see and cut it every day. To get close to a tumor here, onewill have to cut the complex temporal bone but from which direction andhow? Answering to a question like this and many difficult others in oneday was the aim of this meeting. Diverging the attention to the surgicaltechniques and anatomy, rather than the indications of surgery made thisgoal accomplished successfully.There were 30 participants, of almost equal numbers of anatomists,otolaryngologists and neurosurgeons, by coincidence. Even this was givinga good clue about how the chosen field was in the center of clinical andbasic science cooperation. The plenary session started and chaired byRuhgun Basar. The first presentation by Nuran Yener was giving everydetail of clinical anatomy of the temporal bone. Following, Sarp Saracpresented mastoidectomy and facial nerve decompression techniques withbeautiful schematic slides and real operation movies. The movies werecleverly montaged focusing on the important moments and landmarks andcropping out the intervals in between. Otherwise the movies of these longoperations can be more difficult to watch than doing the operation.After a fifteen minute coffee break, the second session started with thebeautiful presentation of Levent Sennaroglu about labyrnthectomy andtranslabyrenthal approach to the cerebellopontine angle. He describedmedial, lateral and inferior approaches which are used for different purposes.The next presentation was about anatomy of the neurovascular structures ofthe cerebellopontine angle by Beliz Tascioglu. Her presentation was mostlyby real photographs and their explanory drawings at each slide. This typeof presentation supplied extreme good orientation to the surgeons besidesteaching the complex anatomy of the region.Ibrahim Ziyal presented the middle cranial and retrosigmoid approach ofthe neurosurgeons. He also demonstrated some operational movies andgave important clues to the surgeons. The discussion became interesting byparticipation of Dr Gokhan Akdemir and his experiences from his studieswith the famous surgeon Dr Mecit Sami.At the lunch everybody was fascinated with the presentations of the morningand waiting impatiently for the practical part which would be held in theanatomy dissection laboratory. The practicals were not less successful. Theanatomy laboratory has almost turned to an operation hall or even betterwith
