SKULL BASE-AN INTERDISCIPLINARY APPROACH, cilt.19, sa.3, ss.203-207, 2009 (SCI-Expanded)
Objective: To analyze the exposure of the jugular foramen afforded by the fallopian bridge technique. Method: The jugular foramen exposure was obtained using the jugular foramen approach combined with the fallopian bridge technique. We applied this technique using 10 temporal bone specimens at a tertiary referral center. The exposure was assessed by means of depth of the dissection field and two separate dissection spaces that were created anteriorly and posteriorly to the facial nerve. Anteroposterior and superoinferior dimensions of the anterior dissection space were 4.4 +/- 1.03 mm and 6.3 +/- 2.49 mm, respectively. The superoinferior and anteroposterior dimensions of the posterior dissection space were 11.7 +/- 2.08 mm and 8.0 +/- 2.95 mm, respectively. The depth of the first dissection field was 8.2 +/- 2.11. mm. After perforating the jugular bulb, the depth of the second dissection field was 16.0 +/- 1.60 mm. Results: The anterior dissection space serves only, as an additional visualization space for anatomical orientation to the jugular bulb. Tumor dissection is to be accomplished mainly, through the posterior dissection space. Conclusion: The fallopian bridge technique should be added to surgical armamentarium for the jugular foramen tumors confined only to the jugular fossa or tumors with middle ear extension.
