Fracture patterns of the nasal septum

Abstract

OBJECTIVE: To evaluate fracture patterns of the nasal septum. STUDY DESIGN: Cross-sectional cadaveric study. SETTING: Synthes research laboratories, Philadelphia, PA. SUBJECTS AND METHODS: Eighteen cadavers were divided into three groups. Group A was subjected to low-level force administered to the nasal tip. Group B underwent moderate-level force and group C high-level force. Cadavers subsequently underwent dissection of the nose and nasal septum. RESULTS: Fracture patterns were apparent and related to the force applied. Fracture patterns were classified into three types depending on the location and extent. Group A was the most variable. Three cadavers were classified as type 1, two as type 2, and one as type 3. The average amount of force required to produce a fracture in this group was 100 N. Group B cadavers all developed type 3 fractures. Group C cadavers primarily developed type 3 fractures except for one that developed a type 1. Fractures were further classified in regard to the septum being displaced off the nasal spine. CONCLUSION: Based on our observation, we conclude that fracture patterns of the nasal septum do exist and appear to be related to the amount of force sustained.
