    • ‘The inferior turbinate was incised, and a bulging tumor in the right maxillary sinus was taken out piecemeal through the maxillary sinus ostium.’
    • ‘Regarding the marked size decrease of maxillary to premaxillary teeth, it seems likely that relative size of the teeth is allometrically and ontogenetically controlled.’
    • ‘The upper dentition, based on socket size, is slightly heterodont, with smaller premaxillary teeth and larger maxillary teeth.’
    • ‘The teeth most often missing are the third molars, second premolars, and maxillary lateral incisors, and other teeth may be reduced in size.’

      • ‘Labial and maxillary palps are transformed to legs (arrows).’
      • ‘It is visible in the third antennal segment, but not the maxillary palps or larval chemosensory organs.’
      • ‘These hybridization results show that the gene is expressed in two olfactory organs: the third antennal segment and the maxillary palp.’
      • ‘In the fruit fly they are located on the antennae and the maxillary palp, an appendage near the fly mouth.’
