  Purpose

Hypothesis: There are 5 support buttresses in the complex osteocartilaginous architecture of the nose.

  1. The membranous septum;
  2. The Right nasal bone;
  3. The Left nasal bone;
  4. The perpendicular plate of the ethmoid;
  5. The vomer, vomerine groove and anterior nasal spine.

Primary Outcome Measures:
  • Normal architecture of the nasal buttresses [ Time Frame: 1 year ] [ Designated as safety issue: No ]

    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.

Groups/Cohorts
Nasal Fracture

67 patients admitted for facial fractures and who undergo routine CT scans of the face are to be studied. 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

The septum is graded from Grade 0 Septum is straight Grade 1 Septum is deviated by less than 1 half the distance from the midline to the nasal turbinate Grade 2 Septum is deviated by more than 1 half the distance from the midline to the nasal turbinate Grade 3 Septum is almost touching the nasal turbinate

  Eligibility

Ages Eligible for Study:   21 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

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.
