TAILIEUCHUNG - Semicircular canal anatomy: Human cadaveric temporal bone study

To investigate semicircular canal anatomy of Vietnamese mature cadavers 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 n08-2018 SEMICIRCULAR CANAL ANATOMY: HUMAN CADAVERIC TEMPORAL BONE STUDY Nguyen Thanh Vinh1; Nguyen Hoang Vu2; Pham Ngoc Chat2 SUMMARY Objectives: To investigate semicircular canal anatomy of Vietnamese mature cadavers 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 16 human corpse heads, 32 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: 16 human corpse heads, 32 ears were selected with average age of (40 - 83 years old). Lateral, anterior osseous and posterior membranous semicircular canal were clearly identified with cranial fossa approach. Lateral, posterior osseous and membranous semicircular canal were clearly identified with transmastoid approach. Membranous semicircular canal was situated in 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 canal system is a component of the vestibular system, contributing significantly to the body's balance function. Anatomically, there are three semicircular canals: lateral, anterior 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 have to depend on images printed in textbooks or models, which cause a lot of difficulties to understand clearly, especially related specialities such as anatomy, neurosurgery and ENT. In the world, many books have been written on .
