TAILIEUCHUNG - Semicircular canal anatomy as seen in microdissection

The article shows semicircular canal anatomy as seen in microdissection; evaluate osseous semicircular canal, membranous semicircular canal and the relationship of semicircular canal with the adjacent anatomical structures. | Journal of military pharmaco-medicine n06-2018 SEMICIRCULAR CANAL ANATOMY AS SEEN IN MICRODISSECTION Nguyen Thanh Vinh*; Tran Ngọc Anh** Nguyen Hoang Vu***; Le Gia Vinh****; Pham Ngoc Chat***** SUMMARY Objectives: To investigate semicircular canal anatomy as seen in microdissection; evaluate osseous semicircular canal, membranous semicircular canal and the relationship of semicircular canal with the adjacent anatomical structures. Subjects and methods: Samples of 9 human corpse heads, 18 ears were selected belonging to Department of Anatomy, University of Medicine and Pharmacy, Hochiminh City. The semicircular canal was explored with transmastoid and cranial fossa approach. Results: 9 human corpse heads, 18 ears were selected with average age (53 - 70). Horizontal, superior osseous semicircular canal and posterior membranous semicircular canal was clearly identified with cranial fossa approach. Horizontal, posterior osseous and membranous semicircular canals were clearly identified with transmastoid approach. Membranous semicircular canal was situated the outer edge of the osseous semicircular canal. Conclusions: All of these approaches can be used to clearly identify the semicircular canal anatomical structure. * Keywords: Osseous semicircular canal; Membranous semicircular canal; Cranial fossa approach; Transmastoid approach. INTRODUCTION The semicircular canals system is a component of the vestibular system, contributing significantly to the body's balance function. Anatomically, there are three semicircular canals: horizontal (lateral), superior and posterior semicircular canals. They are very small structures, in different planes, lied within the earlobe and buried deep in the temporal bones. When studying, researching or teaching, people has to depend on images printed in textbooks or models, which causes a lot of difficulties to understand clearly, especially related specialties such as: anatomy, neurosurgery and ENT. In the world, there are many .
