The study was conducted to describe the distribution of nerve points of the accessory nerve to the trapezius muscle in Vietnamese adult cadavers. A cross-sectional descriptive study was performed on 18 trapezius muscles from fresh frozen cadavers of Vietnamese adults. A total of 142 nerve entry points were identified in 18 trapezius muscles, which were grouped into 6 clusters, each with a corresponding center point. In particular, the upper part of the trapezius muscle had the presence of center points 2 and 3; the middle part of the trapezius muscle had center points 1 and 6; and the lower part of the trapezius muscle had center points 4 and 5. Comparison of these points with anatomical landmarks on the skin revealed that the nerve points entering the trapezius muscle tended to be concentrated in three main areas: about 2 cm above the upper angle of the scapula (located between the C7 spinous process and the acromion); the supraspinous fossa; between the medial border of the scapula and the T4-T6 spinous processes. This study provided important data on the distribution of nerve points entering the trapezius muscle of the accessory nerve in adult Vietnamese cadavers, contributing to providing an anatomical basis to support clinical diagnostic and treatment applications, especially in pain management and therapeutic interventions‎.
