2. Paranasal sinuses
– Air containing bony
spaces present
around the nasal cavity.
– Usually lined by
respiratory mucus
membrane .
– Four paired

3. Maxillary
Sinus
The maxillary sinus is

4. DEVELOPMENTAL A.SPECTS
First sinus to develop
Initial development of sinus follows number
of morphogenic events in differentiation of
nasal cavity

5. Horizontal shift of palatal
shelves and subsequent fusion
with one another.
Nasal septum separates Oral cavity
from nasal chambers
Expansion of lateral nasal wall and 3
walls begin to fold
3 Nasal conchae & 3
meatus
Superior & inferior
- Shallow depression for
half
of IU Life
Middle
- Expansion in lateral wall
and in inferior direction

8. Devevlopmental anomalIues

. Agenesis : complete
absence of maxillary sinus
. Aplasia : incomplete
formation.

9. Developmentalanomalies
3. Hypoplasia :
failure to develop
to normal size
4. Supernumary
maxillary sinus :
more than the usual
number.
