maxillo-turbinals - Collaborative International Dictionary of English v.0.48 :

  Turbinal \Tur"bi*nal\, a. [L. turbo, turben, -inis, a top,
     whirl.] (Anat.)
     Rolled in a spiral; scroll-like; turbinate; -- applied to the
     thin, plicated, bony or cartilaginous plates which support
     the olfactory and mucous membranes of the nasal chambers.
     [1913 Webster]
  
     Note: There are usually several of these plates in each nasal
           chamber. The upper ones, connected directly with the
           ethmoid bone, are called ethmoturbinals, and the
           lower, connected with the maxillae,
           maxillo-turbinals. Incurved portions of the wall of
           the nasal chamber are sometimes called
           pseudoturbinals, to distinguish them from the true
           turbinals which are free outgrowths into the chambers.
           [1913 Webster]
