The frontonasal duct is eliminated by inverting the frontal sinus mucosa
left in the funnel-shaped entrance to the duct upon itself, and then
obliterating the duct with a block of temporalis muscle (Figure 3.8). The
cleansed anterior wall fragments are similarly divested of all their
mucosa with a cutting bur, and then fixed in place with square plates
and miniplates (Figure 3.9). The scalp is closed and a light-pressure
dressing is applied.

Cranialization procedure—The
mucosa of the sinus is removed
from the sinus lumen, the
frontonasal duct mucosa is inverted
on itself, and the frontonasal ducts
are plugged with temporalis muscle.
