The CT diagnostic value of nasal bone fractures and its significance for forensic identification
鼻骨骨折的CT诊断价值及其对法医鉴定的意义

摘要

鼻骨骨折是临床上常见的外伤类型，对鼻骨骨折的诊断精度和损伤程度的判断，直接关系到司法公正和当事人的权益。CT以其较高的空间分辨率和多角度成像优势，已成为诊断鼻骨骨折的“金标准”。鉴于此，本文通过分析鼻骨及周围结构解剖特征，并着重探究不同CT技术对鼻骨骨折的检出、分型、合并伤损评价的价值，探索其在法医学损伤程度鉴定、致伤方式推断、新伤与陈旧性骨折鉴别等核心环节中的支撑作用，并针对目前研究现状和现实争议，提出基于CT诊断和法医学鉴定协同优化的方法，以期为提高司法鉴定的期待度提供理论依据。

Abstract

Nasal bone fracture is a common type of trauma in clinical practice. The diagnostic accuracy and the judgment of the degree of injury of nasal bone fracture are directly related to judicial fairness and the rights and interests of the parties involved. CT, with its high spatial resolution and multi-angle imaging advantages, has become the "gold standard" for diagnosing nasal bone fractures. In view of this, this paper analyzes the anatomical features of the nasal bone and its surrounding structures, and focuses on exploring the value of different CT techniques in the detection, classification, and evaluation of combined injuries of nasal bone fractures. It also explores its supporting role in the core links of forensic injury degree identification, injury mode inference, and differentiation between new and old fractures. In light of the current research status and practical controversies, A method based on the collaborative optimization of CT diagnosis and forensic identification is proposed, with the aim of providing a theoretical basis for enhancing the expectation of judicial identification.
