The PSSS offers a new way of looking at CT sinus disease in a pediatric population which includes a change in the grading of opacification, the incorporation of a multiplier for underdeveloped sinuses, and a correction score for absent sinuses.
The paranasal sinuses (maxillary, frontal, ethmoid, and sphenoid sinuses) are complex anatomical structures. The development and growth of these have been investigated utilizing a number of different methods ranging from cadaveric analysis to modern cross sectional imaging with 3D modeling.
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.

The most widely accepted theory is that an inciting event causes occlusion of the ostiomeatal complex through which the maxillary sinus drains into the middle meatus of the nasal antrum.
Results: Eighty-three children were identified to have maxillary sinus hypoplasia. Eighty-one patients had maxillary sinus opacification and 57 patients had hypoglobus or enophthalmos characteristic of SSS.
