“…This complex structure of the frontal sinus in horned animals acted as shock absorbent during fighting to protect the vital cranial structures. On the other hand, this bony irregularity impaired the sinuscopic evaluation of the frontal sinus; however, the maxillary sinus was easily inspected due to its regular bony structure (Basso et al, ). The rostral part of the frontal sinus had 3–4 foramina which communicated with the nasal cavity that could assist the natural drainage of the accumulated fluids from this sinus.…”

The present work aimed to describe the normal computed tomography (CT) and cross‐sectional anatomy of the nasal and paranasal sinuses in sheep and to correlate these features with the relevant clinical practices. Twenty apparent healthy heads of Egyptian native breed of sheep (Baladi sheep) of both sexes were used for studying these sinuses. CT images and their closely identical cross sections of the same head were selected and serially labelled in a progression from the rostral nasal region to the caudal aspect of the head using cheek teeth as landmarks. The current investigation reported seven sinuses in sheep, including maxillary, frontal, lacrimal and sphenoidal as paranasal, as well as dorsal and middle conchal and ethmoidal as nasal with unnoticeable palatine and ventral nasal conchal sinuses. The boundaries, extension, structure and communications of these sinuses were fully described. The current study provided anatomical guidelines for surgical interference in the frontal and maxillary sinuses during trephination, dehorning and sinuscopy. Also, an acceptable anatomical explanation was reported in this study for the high incidence of maxillary sinusitis than other sinuses. CT and cross‐sectional anatomy could be used as helpful database for diagnosis and clinical interference of the nasal and paranasal sinuses in sheep.

“…On the other hand, two sites were selected either in sheep (May, ) and buffalo (Farag et al, ). Furthermore, Basso et al () identified three main areas for trephination comprising the nuchal diverticulum, the caudal region of the sinus as well as the post‐orbital region in cattle.…”

“…Regarding the sphenoidal sinus, it was absolutely recognized in camel (Alsafy et al., 2014), Egyptian sheep (Awaad et al., 2019) and buffalo (Alsafy et al., 2013). However, palatine and sphenoid sinuses were not observed in goat (May, 1970; Sisson & Grossman, 1975; Tohidifar et al., 2020), buffalo (Alsafy et al., 2013), camel (Alsafy et al., 2014) and cattle (Basso et al., 2016).…”

Background CT scan images provide accurate anatomical data from different areas of the body that can be used to diagnose diseases. Objectives The present work aimed to describe the normal anatomical structures of the Ile de France sheep head and its morphometric and volumetric properties using computed tomography (CT) and stereological methods. Methods Five adult Ile de France sheep heads, which were of mature age (above 10 months), were included in this study. The different cavities of the head, including the nasal cavity, paranasal sinuses, oral cavity, orbital cavity and vestibulocochlear system, were evaluated using CT scans, cross, sagittal and coronal sections. Results The mean length, height and width of the skull were 25.3 ± 1.02, 9.8 ± 0.93 and 12.3 ± 0.91 cm, respectively. The results showed that the nasal cavity is divided into three regions. Vestibular, respiratory and olfactory regions. The paranasal sinuses are composed of maxillary, frontal, palatine, sphenoid, lacrimal and ethmoidal that were identified and named in the CT scan images and their corresponding anatomical cross‐sections. The total volume of the head, nasal cavity and oral cavity was estimated to be 2998 ± 202.00, 303 ± 31.33 and 229.3 ± 10.61 cm3, respectively. Conclusions The frontal sinus in the Ile de France sheep was limited to the frontal bone without extending into the parietal, temporal, or occipital bones, similar to Saanen goat. This study provided a comprehensive atlas of Ile de France sheep anatomy to internal medicine veterinarians and surgeons.
