Table 2
The nasal dimension measurements—anterior, middle-third and posterior part.
| | Abbreviation | Measurement |
|
Anterior nasal cavity | ABW | Anterior bony width between the two ridges extruding from the maxilla-pyriform aperture | RABW* | Right anterior bony width from the right maxillary ridge to the septal mucosa | LABW* | Left anterior bony width from the left maxillary ridge to the septal mucosa | AMW* | Anterior mucosal width between two mucosal edges extruding from the maxilla including the anterior airspace and the global thickness of the septum | RAMW* | Right anterior mucosal width between the lateral mucosa and the septal mucosa | LAMW* | Left anterior mucosal width between the lateral mucosa and the septal mucosa |
|
Middle-third nasal cavity | MMW | Minimal soft tissue width from the mucosa of one inferior turbinate to the other | | Right minimal soft tissue width from the turbinal to the septal mucosa | | Left minimal soft tissue width from the turbinal to the septal mucosa |
|
Posterior nasal cavity | BCAW | Bony choanal aperture width between both pterygoid processes-choanal aperture | RPBW# | Right posterior bony width between bone sidewall and septal mucosa | LPBW# | Left posterior bony width between bone sidewall and septal mucosa | RPMW# | Right posterior mucosal width between the lateral mucosa and the septal mucosa | LPMW# | Left posterior mucosal width between the lateral mucosa and the septal mucosa | MVW | Maximal width of vomer |
