Abstract

Objectives: To determine the ratio of the nasal bone shapeand the histological features of the frontonasal suture. Methods: cross-sectional descriptive studies on the nasal bones from dried Vietnameses corpses at the Anatomy Department of Pham Ngoc Thach University of Medicine from June 2019 to January 2021. By the directly examination of the nasal bone and frontonasal suture on the straight, the right and the left side, the histological examination with HE in the 69 department. Results: There are 33 nasal bones, with 45.5% female, the age range from 20 to 87 years old, the average age is 65 years. The proportion of nasal bones with K is 24.2%. Most of the nasal bones are the V-shaped with 81.8% on the lateral side. The major shape is type A (57.6%) and type B (30.3%) on the straight side. About the frontonasal suture, the major ratio is the B type with 45.5%. On the six histological samples examination, the frontonasal sutures are dense. The average distance of the joint is 0.22mm; the periosteum in the nasal and frontal bones is alternatively 0,38 ± 0,13mm and 0,42 ± 0,15mm. There is the correlation between the periosteum thickness at three sites: the nasal bone, the frontal bone and the nasion. Conclusion: Macro and micro anatomical characteristics of the nasal bone and frontonasal sutures is very important in the anthropometry and rhinoplasty. We need more research about these featuresin the future to determine them.
