Abstract:
Objective To study the surgical approach of the jugular foramen and the clinical anatomy of the transmastoid endoscoPy-assisted jugular foramen surgery.Method The transmastoid endoscopy-assisted jugular foramen surgery was simulated in 15 adult cadaveric specimens(3O side). The main anatomic mark in the surgical approach was studied,and the distance between the important stmcture to the glomus jugular has been measured. Results The distance between the glomus jugular and the Vertlcal segmental of the facial nerve,the anterior wall of the glomus jugular to the facial nerve,the glomus jugular to the posterior semicircular canal and tympanic cavity were(3.58±1.32)mm,(5.07±2.93)mm,(4.68±3.47)mm and(0.14±4.32)mm.In 30 cases,the top of the glomus jugular inferior the tympanic cavty in 5cases, 7 cases behind the facial nerve and the tympanic, 16 cases the facial Berve is m the middle of the glomus iugular. 2 cases is near the inferior wall of internal auditory meatus.the cranial nerve and blood vessel in the jugular foramen is clearly to be show. Conclusion It is a samPle and little damaged way to use the transmastoid endoscopy-assisted jugular foramen surgery and it is hopeful to Protect function of the facial Berve,acoustic nerve and the post-cranial nerve.
