Answer
|
The maxillary sinus
communicates with the environment via the
|
Middle nasal meatus
|
The initial event leading to
development of maxillary sinus is at when the embryo is
|
32 millimeters
|
During embroyogenesis of maxillary
sinus, lateral nasal wall begins to fold to form
|
Three nasal conchae ; three
nasal meatus
|
The nasal meatus expands
immediately into nasal wall as it is formed
|
Middle nasal meatus
|
During embroyogenesis of
maxillary sinus the middle nasal meatus expands in a
|
Inferior direction
|
During embroyogenesis of
maxillary sinus the middle nasal meatus expands in an inferior direction due
to the presence
|
Lateral nasal capsule
|
The maxillary sinus is of 1
millimeter in diameter when the embryo is
|
50 millimeters
|
The maxillary sinus has
developed its sinus epithelium when the embryo is
|
50 millimeters
|
The anteroposterior diameter of
maxillary sinus perinatally is
|
7 - 16 millimeters
|
The maxillary sinus expands and
modify itself till
|
All permanent teeth erupt
|
The most common cause of
supernumerary maxillary sinus is
|
Outpocketing of nasal mucosa at
two points
|
Supernumerary maxillary sinus
have
|
Two ostia
|
The best way to describe a
maxillary sinus is a
|
4 sided pyramid
|
The inferior surface of the
maxillary sinus is formed by
|
Alveolar and zygomatic process
|
The four sinus wall converge
laterally at an
|
Obtuse angle
|
The perforation of the
maxillary sinus, ostium is seen at
|
Base of sinus
|
The maxillary sinus ostium is
at the level of
|
Middle nasal meatus
|
The expansion of pneumatic
spaces of maxillary sinus beyond the
maxillary body is referred to as
|
Recesses
|
The most common recesses of
maxillary sinus involves the
|
Alveolar process
|
The occurrence of zygomatic
recesses brings the space of maxillary sinus in proximity with
|
Superior alveolar nerve bundles
|
The presence of alveolopalatine
recesses indicate that the bone between tooth apex and sinus is
|
Thinner
|
The most commonly involved
tooth with alveolopalatine recesses is the roots of
|
Maxillary first molar
|
A fully well developed alveolar
recesses have
|
Three depressions; 2 incomplete
bony septa
|
The epithelial layer of
maxillary sinus can be best described as
|
Pseudostratified, columnar and
ciliated
|
The epithelial layer of
maxillary sinus is derived from
|
Olfactory epithelium
|
The numerous cells in the
maxillary sinus epithelium is the
|
Columnar ciliated cells
|
The attachment of ciliary
microtubules to the maxillary sinus epithelial cells is facilitated by
|
Basal bodies
|
The basal bodies of the
maxillary sinus epithelial cells are found in the
|
Apical segment
|
The typical cilia of the
maxillary sinus epithelial cells are made of
|
9 + 1 pair of microtubules
|
The cilia facilitates the
movement of mucous lining the maxillary sinus epithelium generally from the
|
Sinus interior toward nasal
cavity
|
Congenital syphilis affect
maxillary sinus causing the sinus to be
|
Smaller
|
The maxillary sinus is also
known as
|
Antrum of Highmore
