* Nasion (N)--the most anterior point of the nasofrontal
suture in the midsagittal plane,
In addition, nasofrontal
and nasolabial angles were measured pre..and post.operatively.
Sekiguchi and Savara showed that nasion (N) might be challenging to locate when the nasofrontal
suture is not clearly seen and it has been reported thatmenton, nasion and posterior nasal spine were also sources of errors this might have contributed for the difference in SNB.
Computed tomography (CT) of the sinuses revealed a large, septated, left frontal sinus with evidence of obstruction of the nasofrontal
duct and mucosal thickening (figure, A).
(2003) also found through their study among Galicians a nasofrontal
angle of 138 [+ or -] 5.7[degrees] for males and 141 [+ or -] 9.8[degrees] for females (4).
Sincipital cephaloceles are classified as nasofrontal
, nasoethmoidal, nasoorbital, or combined and basal cephaloceles as transethmoidal, sphenoethmoidal, sphenoorbital, sphenomaxillary, and transsphenoidal.
The endoscopic approach is even more challenging when a nasofrontal
angle correction is also desired.
Significant decreases in the nasofrontal
angle and nostril height were also found (7, 14).
Nasal volume increase, nose height increment, increase in nasolabial, nasofrontal
, and nasomental angle, decrease in nose length, and nasofacial angle were observed.
duct injury is also important to document, occurring in 70% of all fractures .
