Table 2

The nasal dimension measurements—anterior, middle-third and posterior part.

AbbreviationMeasurement

Anterior nasal cavityABWAnterior 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 cavityMMWMinimal 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 cavityBCAWBony 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
MVWMaximal width of vomer
