[Abstract]:Objective: to study the anatomical study and data measurement of modified labyrinthine sublabyrinthine approach with posterior semicircular canal resection, open internal auditory canal, and provide anatomic markers, parameters and basis for internal auditory canal operation. The superiority and safety of this method are discussed. Methods: 20 adult cadaveric heads fixed with 10% formaldehyde were dissected by the modified sublabyrinthine approach under microscope (脳 6 ~ (16)). The width of the middle part of sigmoid sinus, the shortest distance from the anterior edge of the sigmoid sinus to the vertical segment of the facial nerve, the height of the jugular bulb and the distance from the top of the jugular bulb to the inferior edge of the internal auditory canal were measured. The distance from the top of the jugular bulb to the superior edge of the auditory canal, the distance from the posterior edge of the horizontal semicircular canal to the dura mater of the posterior cranial fossa, the height of the superior and inferior diameter of the auditory orifice and the length of the internal auditory canal. The data were analyzed by SPSS11.5 or PEMS software package. Results: the occurrence rate of mastoid conduction vessels was 80 / 32 / 40). The external orifice of mastoid conduction vessel was located in front of occipital-mammary suture. The width of middle part of sigmoid sinus was 10.63 鹵1.91 mm. The shortest distance from the anterior edge of the sigmoid sinus to the vertical segment of the facial nerve was 9.84 鹵2.48 mm. The height of jugular bulb was 5.40 鹵1.48 mm; The distance from the top of the jugular bulb to the inferior edge of the internal auditory canal was 3.03 鹵1.93 mm; The distance from the top of the jugular bulb to the superior edge of the internal auditory canal was 8.24 鹵2.36 mm. The distance between the posterior margin of horizontal semicircular canal and the dura mater of posterior cranial fossa was 5.60 鹵1.28 mm. The height of the upper and lower diameter of the internal auditory entrance was 4.13 鹵0.85 mm; The posterior wall of the internal auditory canal was 8.74 鹵1.31 mm in length. The exposure length of the internal auditory canal was 5.45 鹵1.04mm in 33 sides of the internal auditory canal exposed through the modified inferior labyrinthine approach, accounting for 61.52 鹵10.00 mm of the total length. Resection of posterior semicircular canal arch. The visual field of bone window was 5.60 鹵1.28mm 脳 8.24 鹵2.36mmm. the height of jugular bulb was negatively correlated with the shortest distance from the top of jugular bulb to the inferior edge of internal auditory canal. R-0.742. P < 0.01. Conclusion: 1. The improved sublabyrinthine approach to open the internal auditory canal can significantly enlarge the visual field of bone window. 2. The height of jugular bulb was negatively correlated with the distance from the top to the inferior edge of the internal auditory canal, and the inferior labyrinthine approach was improved.
