Abstract:
BACKGROUND AND OBJECTIVES: Anatomical knowledge of the petrous apex is essential to otolaryngologist to explore the skull base lesions. This study was designed to investigate the surgical anatomy of the petrous apex and the middle cranial fossa. MATERIALS AND METHODS: We dissected 32 temporal bones in order to establish the anatomical relationships of petrous apex structures. We measured distances and angles between different structures so that surgeons can rely on to work in this area. RESULTS: The results of the present study showed distances and angles of the different petrous apex structures. The angle between posterior point-foramen spinosum and porus was 90 degree. CONCLUSION: We could suggest the new indicators to identify the internal acoustic canal.
