Paranasal Sinuses: Changes with Age
ANATOMY
Sphenoidal sinus within bony shell (sphenoidal concha) located anterior and lateral to body of sphenoid bone (broken line indicates sinus lateral to sphenoid body), Sinuses represent two or more posterior ethmoidal cells opening into superior nasal meatus, Sinus
represents one or more middle ethmoidal cells opening into
middle nasal meatus.
Body of sphenoid bone, Lower border of superior nasal concha, Lower
border of highest nasal concha, Uncinate process of ethmoid bone, Bones of
nasal cavity and paranasal sinuses at birth, Part of nasolacrimal duct that
formed in depths of nasooptic furrow, Part of nasolacrimal duct within nasal
cavity with slit-like opening in inferior nasal meatus, Growth of frontal and
maxillary sinuses throughout life, Maxillary sinus with opening into semilunar
hiatus (striped area represents membrane forming most of medial wall of sinus),
Middle nasal concha (cut edge) (inferior nasal concha completely removed).
Maxillary sinus within maxillary bone ethmoid bone, Palatine bone, Pterygoid Hamulus, Semilunar hiatus, Maxillary
sinus with op, Maxillary bone, Superior nasal meatus, Hypophyseal
fossa, Left orbit, Molar tooth, Middle nasal
concha, Nasal septum Nasal cavity, Inferior nasal concha, Palate.
