“…In other investigations using CT in the region of the feline nasal cavity these settings have varied exceedingly, from 2-10 mm. [26][27][28] However, to adequately identify the tiny structures of the NDS and the inconspicuous osseous surroundings, a high resolution scan with the smallest possible slice thickness is necessary, allowing evaluation and 3D reconstruction. Three-dimensional models are suitable for gaining a better understanding of ✜ Rotation of the upper canine teeth seems to provide a provisional basis on which brachycephalia can be classified, and may be used by breeders and breeding judges for subjective classification and for selection of individuals for breeding.…”

Aims A study was designed to evaluate the influence of head conformation on the course of the nasolacrimal drainage system (NDS) in 31 brachycephalic and 15 mesocephalic cats using computed tomography (CT), CT-dacryocystography and anatomical methods. Findings The higher the degree of brachycephalia, the more the facial bones and upper canine teeth are displaced dorsally (ie, the more pronounced the dorsorotation). Dorsorotation leads to abnormal dislocation of the ventral nasal concha and to almost horizontally rotated upper canine teeth, and thus a steeply oriented NDS. In severe brachycephalia the NDS is forced to pass below the canine tooth (adopt a V-shaped course) and the drainage function seems to be inefficient. Practical relevance The rotation of the upper canine teeth appears to provide a basis for classification of brachycephalia in cats. The authors recommend that breeders avoid breeding from individuals affected by this condition and to give preference to cats with longer facial bones.

“…The morphology of these sinuses is studied in several animals: small ruminants (May, ; Sisson, ), domestic animals (Dyce et al, ; Frandson, Wilke, & Fails, ; König & Liebich, ), buffalo (Alsafy, El‐Gendy, & El Sharaby, ; Farag, Hagrass, Daghash, El‐Bably, & Sary, ; Moustafa & Kamel, ; Saigal & Khatra, ) and camel (Alsafy, El‐Gendy, & Abumandour, ). As the relevant clinical applications in correlation to the gross anatomy of the paranasal sinuses are remained inadequate especially in sheep, so, it is necessary to understand the definite position, extension and communication of these sinuses for improvement the diagnosis of the upper respiratory tract disorders (Losonosky, Abbott, & Kuriashkin, ; Reetz, Mai, Muravnick, Goldschmidt, & Schwarz, ). Due to the position of the paranasal sinuses close to the vital structures in the head region as the brain, eye and major arteries, therefore, any surgical interference requires a high degree of accuracy (Burschka, Li, Ishii, Taylor, & Hager, ).…”

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.

“…11,12 It is well documented that odontogenic pathology is a cause of sinusitis in humans but the actual prevalence is debated. 7,[29][30][31][32][33][34] In dogs and cats, the maxillary tooth roots are juxtaposed to the nasal cavity, whereas in humans they are juxtaposed to the maxillary sinuses. 11,13,14,[18][19][20][21][22][23] Respiratory mucosal pathology occurs secondary to periodontal and endodontic infections.…”

The role of odontogenic infection as an etiology for lymphoplasmacytic rhinitis in dogs was evaluated. An association between odontogenic infection and inflammatory rhinitis was identified in 55% of cases evaluated. Odontogenic infection was unlikely or undetermined in 10% and 35% of the cases, respectively. Cases of lymphoplasmacytic rhinitis had roentgen signs associated with endodontic disease, periodontal disease, or retained tooth roots in 60%, 45%, and 25% of the cases, respectively. A collaborative team based approach assessing inflammatory nasal disease is recommended. Based on the history and signalment of the individual patient, diagnostic modalities should be chosen wisely. In some cases, oral examination and intraoral radiographs may be a more direct and cost effective approach for diagnosis and treatment of inflammatory rhinitis.
