... Numerous techniques for nasal tissue sampling have been described, including fine needle aspiration biopsy of facial deformities, nasal flush cytology (Withrow 1977), brush cytology (Caniatti et al. 2012), high pressure nasal hydropulsion (Ashbaugh et al. 2011), rhinoscopic pinch biopsy (Lent & Hawkins 1992), blind per-nostril biopsy, catheter core biopsy (Love et al. 1987, Lent & Hawkins 1992, "TruCut" biopsy and surgical rhinotomy. ...

... [1][2][3] Significant differences exist in the structural anatomy of the middle ear between these species; namely, the presence of an incomplete bony septum within the feline tympanic bulla that divides it into a smaller dorsolateral component, composed of the epitympanum and mesotympanum, and a larger ventromedial hypotympanum. 4,5 In combination with the relatively deep tympanic chamber of the cat, this septum can impede complete penetration into the deeper portion of the tympanic bulla, limiting the surgeon's ability to fully ablate the epithelium of the bulla. In fact, previous research has shown that even experienced surgeons may fail to completely enter the hypotympanum through the septum up to 25% of the time during feline TECA-LBO procedures. ...

... In the acquired EACA of dogs and cats, septic inflammatory exudate and dark brown ear wax material can be found, abscesses and fistulas may be formed around the ear with a history of accidents or chronic ear inflammation (6,11,14,16). According to a previous report in dogs, untreated congenital EACA causes inflammation such as otitis externa and otitis media due to abnormal accumulation of hair and ear wax (2,15), also the para-aural abscess can be formed (12). Our case is considered to be similar to the untreated congenital EACA case, after the development of otitis externa and otitis media, the possibility of exposure of bacteria due to the spread of inflammation to surrounding tissues could be considered. ...

... cases of cervical abscesses (CAs) without identifiable foreign material. The current literature [2][3][4][5][6] describes CAs in dogs primarily in relation to identifiable foreign material, such as wood fragments, wound tracts, or gas pockets consistent with a penetrating injury or grass awns. Grass awns, although reported in cases of CAs, are more commonly associated with abscesses in alternate locations such as the external ear canal and interdigital webbing. ...

... If an underlying case of otitis media is present at the time of operation, unsatisfactory outcome is likely [20]. Otitis media can develop as a result of otitis externa; it has been documented in 16% of early episodes of otitis externa and in 52% to 83% of dogs with chronic otitis externa [21,22]. ...

... Facial swellings in horses can be attributed to different causes including traumatic lesions (Bladon and Lane 1997), cystic expansile lesions (Tremaine and Dixon 2001a;Tremaine and Dixon 2001b;Rush and Mair 2004), or neoplasia (Tremaine and Dixon 2001a,b;Dixon 2014). Although the occurrence of cystic lesions is not very common, they can cause marked deformation of the bones of the skull as they progressively increase in size (Caldwell 2014). ...

... Apart from bit-induced pain [43], mouth pain is commonly related to dental disease in domestic horses [44][45][46]. Li le is known about the prevalence of dental pathology encountered in wild horses. Although it is postulated that more time spent chewing higher fibre diets with the head in a natural grazing position may lead to fewer dental disorders in wild horses compared with domestic horses, this has not yet been studied. ...

... Other authors describe, that the initial step in establishing paranasal sinus disease is the stagnation of mucociliary clearance, which can become chronically and lead to a mucosal hyperplasia. This hyperplasia contributes to the pathways occlusion [21]. In literature, mucosal hyperplasia in paranasal sinus disease up to 15 mm is described [22]. ...

... [22][23][24][25] The radiological finding of metaplastic calcification in the sinus of horses has been reported previously and was always associated with dental fractures and attachment of the calcified mass to the sinus wall. 26 The calcifications retrieved from the sinus in our case consisted histologically of woven bone, prompting us to propose the term ectopic ossification for this case. Moreover, the reported cases of radiographically identified metaplastic calcification lack histologic analysis that renders speculation on their etiopathogenesis difficult. ...
