ABSTRACT
To study an improved translabyrithine approach, twenty adult cadaver heads (40 sides) fixed with formalin were dissected by mimicking translabyrithine method under light microscope ,and measurements were performed . The results showed that the rate of meeting with mastoid emissary was 33/40(82. 50%). The distance between the middle part of sigrnoid and the vertical part of facial nerve was 7. 22 ?1.95 mm. The width of the middle part of sigmoid was 10. 5 ? 0. 79mm, the left side was 8. 89 ? 1. 03mm, and the right side was 9. 88 ?2.14mm. The height of jugular bulb was 8. 08?3. 46mm,the left side was 6. 78 ? 3. 17mm,and the right side was 9. 07?3. 04mm. The distance between the highest point of jugular bulb and the base of internal acoustic meatus was 4. 54 ? 2. 81 mm, the left side was 5. 93?3. 12mm, and the right side was 2. 65?1. 87 mm. The distance between the inferior margin of internal acoustic meatus aperture and superrior petrosal sinus was 5. 09?1. 29mm . The diameter of superrior petrosal sinus was 1. 43?0. 08 mm. There were two types of superrior petrosal sinus entering to the sigmoid (or transverse sinus). The angle between superrior petrosal sinus and sigmoid was 52. 17 ?6. 93?. The results suggest that the improved translabyrithine approach can give enough vision for cerebellopontine angle operation.
