简要总结
Hypothesis: There are 5 support buttresses in the complex osteocartilaginous architecture of the nose.
- The membranous septum;
- The Right nasal bone;
- The Left nasal bone;
- The perpendicular plate of the ethmoid;
- The vomer, vomerine groove and anterior nasal spine.
详细描述
Aim:
- Study the 3-dimensional anatomy of the nasal buttresses.
- Diagnose fracture patterns in the nasal buttresses.
- Identify the buttress fractures associated with deviation of the external nasal morphology.
- Identify the buttress fractures associated with septal deviation.
- Assess the airflow patterns and its associated distribution of flow velocity, pressure, and wall shear stress in the nasal cavity for patient specific models with nose fracture.
- Assess the stress distribution in the nasal bone structures subject to various scenarios of loading conditions.
Methodology:
67 consecutive patients admitted for facial fractures and who undergo routine CT scans of the face with our protocol of axial and coronal sections taken at 0.6mm and gantry 0 are to be studied. The CT scans are evaluated to assess the position, comminution and displacement of the 5 said buttresses.
The buttresses are graded Grade 1 Simple fracture without displacement Grade 2 Simple fracture with displacement Grade 3 Comminuted fracture without displacement Grade 4 Comminuted fracture with minimal displacement Grade 5 Comminuted fractured with displacement

结局指标
主要结局
Normal architecture of the nasal buttresses
时间窗: 1 year
To impact current clinical practice and improve the treatment outcomes by utilizing CT scans to analyze 1. Normal architecture of the nasal buttresses; 2. Fracture patterns of the buttresses associated with septal deviation and changes to the external nasal morphology; 3. Weakest buttress as seen by the highest frequency of fracture; 4. Strongest buttress as seen by the lowest frequent of fracture; 5. Assessment of nasal patency due to the changes in nasal morphology before and after the surgical correction.
