“…The association between middle ear disease and nasal disease on CT scans in cats has been documented previously . The prevalence of middle ear disease in cats with nasal disease in this earlier study was 28% (13/46), which is similar to the 23% (27/118) found here.…”

“…This model potentially mimics some nasal and upper respiratory diseases in which mucosal inflammation and temporary auditory tube obstruction result in middle ear effusion. Viral upper respiratory tract infections may also predispose to bacterial colonization of the nasopharynx and ascending bacterial middle ear infection via the auditory tube …”

“…Middle ear disease in cats is associated with the growth of inflammatory polyps, neoplasia, extension of external ear canal infection into the middle ear, and auditory tube obstruction or dysfunction secondary to nasal or upper respiratory disease . The prevalence of subclinical middle ear disease in the cat is not well documented.…”

“…In one study of radiographic, ultrasonographic, and CT evaluation of the middle ear, five of 84 cats (6%) were excluded as normal controls because they had fluid in the tympanic bulla . Twenty‐eight percent of cats with sinonasal disease had CT findings of subclinical bulla effusion in a second study . Our purpose was to determine the prevalence of subclinical middle ear disease among a large population of cats undergoing CT imaging of the head.…”

Three hundred and ten cats that had CT imaging of the head between January 2000 and December 2007 were evaluated retrospectively. Data that were recorded included signalment, presenting complaint, clinical signs, presence of upper respiratory tract disease, and CT findings. One hundred and one cats had evidence of middle ear disease on CT. Thirty-four of the 101 cats (34%) did not have a primary complaint of ear-related disease, clinical signs or physical findings consistent with ear disease, suggesting that the middle ear disease was subclinical. Twenty-seven of the 34 cats (79%) had concurrent nasal disease. Middle ear lesions were chronic in appearance. With the exception of tympanic bulla lysis, CT findings were similar in cats presenting with primary aural disease versus cats with presumptive subclinical middle ear disease. The majority of the cats did not return for treatment of the identified middle ear abnormalities. Subclinical middle ear disease is relatively frequent in cats undergoing CT imaging of the head. Few cats required subsequent treatment for ear disease although follow up was limited. Identification of subclinical middle ear abnormalities on CT should prompt acquisition of a detailed patient history and bilateral otoscopic examination.

“…Similar changes were found in Cavalier King Charles spaniels, where a greater thickness of the soft palate and reduced nasopharyngeal aperture were significantly associated with subclinical otitis media . Presence of concurrent middle ear pathology in dogs and cats with soft palate abnormalities and bulla effusion in cats with sinonasal disorders has also been reported . Two recent publications reported the presence of middle ear effusion in dogs with trigeminal nerve dysfunction due to denervation of the tensor veli palatine muscle and secondary persistent Eustachian tube obstruction impairing its normal drainage .…”

Prevalence of subclinical middle ear lesions in dogs that undergo computed tomography (CT) and magnetic resonance imaging of the head has been reported up to 41%. A predisposition in brachycephalics has been suggested, however evidence-based studies are lacking. Aims of this retrospective cross-sectional study were to compare CT characteristics of the middle ear in groups of nonbrachycephalic and brachycephalic dogs that underwent CT of the head for conditions unrelated to ear disease, and test associations between thickness of the soft palate and presence of subclinical middle ear lesions. One observer recorded CT findings for each dog without knowledge of group status. A total of 65 dogs met inclusion criteria (25 brachycephalic, 40 nonbrachycephalic). Brachycephalic dogs had a significantly thicker bulla wall (P = 2.38 × 10(-26)) and smaller luminal volume (P = 5.74 × 10(-20)), when compared to nonbrachycephalic dogs. Soft palate thickness was significantly greater in the brachycephalic group (P = 2.76 × 10(-9)). Nine of 25 brachycephalic dogs had material in the lumen of the tympanic cavity, compared to zero of 45 of nonbrachycephalics. Within the brachycephalic group, a significant difference in mean soft palate thickness was identified for dogs with material in the middle ear (12.2 mm) vs. air-filled bullae (9 mm; P = 0.016). Findings from the current study supported previous theories that brachycephalic dogs have a greater prevalence of subclinical middle ear effusion and smaller bulla luminal size than nonbrachycephalic dogs. Authors recommend that the bulla lumen volume formula previously developed for mesaticephalic dogs, (-0.612 + 0.757 [lnBW]) be adjusted to 1/3(-0.612 + 0.757 [lnBW]) for brachycephalic breeds.
