(B) Non-CF and (C) CFTR^−/− newborn piglet three-dimensional sinus scan with ethmoid (red) and maxillary (green) sinus. Dotted line dividing anterior and posterior ethmoid sinus. Volumetric analysis performed on three-dimensional reconstructions of segmented sinus computed tomography scans. Data points represent mean ± standard error of non-CF (n = 7; open symbols) and CFTR^−/− (n = 8; closed symbols) littermate pigs. *P < .05. (C) Volume of ethmoid and maxillary sinuses. (D) Volume of skull. (E) Weight of newborn pigs.
