AB  - The  maxillary  sinuses  are  the  first  of  the  paranasal  sinuses  to  develop.  In  the  neonate,  the  maxillary  sinuses  are  quite  small  and  may  be  partially  or  completely  opacified.  The  maxillary  sinuses  grow  progressively  until  the  end  of  puberty.  They  reach  the  plane  of  the  hard  palate  by  9  years  of  age.  Asymmetry  of  the  maxillary  sinuses  is  common.  The  drainage  ostium  of  the  maxillary  sinus  is  located  superomedially.  It  empties  into  the  infundibulum,  which  is  located  between  the  lamina  papyracea  and  the  uncinate  process.  The  infundibulum  opens  into  the  middle  meatus  through  the  hiatus  semilunaris.  The  maxillary  sinuses  become  visible  on  standard  radiographs  at  approximately  2  to  3  months  of  age.1,2
