Mice models were used to study the pathogenesis of mice and human diseases. Although some mice models of allergic rhinitis and rhinosinusitis have been reported, no detailed anatomic, histological and computed tomographic comparative data of the normal murine sinus are available in the literature for new researchers to establish mice models. The purpose of this study was to clarify the histological and computed tomographic characteristics of the normal nasal sinus in BALB/c mice. Fifteen sinonasal specimens were collected. Five mice were subjected to micro-computed tomography imaging, and then dissected to observe its anatomic landmarks, and 10 mice were subjected to haematoxylin and eosin staining. Important anatomic landmarks were clearly demonstrated, including the ethmoturbinates, nasoturbinal, maxilloturbinate, ethmoid sinus, maxillary sinus, nasopharyngeal duct, nasolacrimal duct and vomeronasal organ. Full and typical sinonasal landmarks can be visualized by gross anatomy, micro-computed tomography imaging and haematoxylin and eosin staining, which will be useful for establishing the mouse models of nasal disease.
