“…Otitis Media with Effusion, OME) [14,15]. Niezdiagnozowany OME może prowadzić do czasowych lub stałych przewodzeniowych ubytków słuchu [16][17][18]. Określenie czynności trąbki słuchowej przed zabiegami operacyjnymi w uchu środkowym często decyduje o powodzeniu leczenia lub jego braku [19,20].…”

Trąbka słuchowa jest chrzęstno-kostnym przewodem łączącym jamę bębenkową z częścią nosową gardła. Jej głównym zadaniem jest wyrównywanie ciśnień między uchem środkowym a częścią nosową gardła oraz drenowanie zawartości jamy bębenkowej do gardła.Testy oceniające drożność trąbki słuchowej zajmują istotne miejsce w praktyce audiologicznej. Niektóre z nich wykonywane są przy użyciu mostka impedancyjnego. Istotą tych testów jest ocena przesunięć wykresu krzywej tympanometrycznej wzdłuż osi odciętych układu, będących konsekwencją zmian ciśnienia powietrza w obrębie ucha środkowego.

“…By that time, irreversible damages might have taken place. Experimental studies in Chinchillas have demonstrated that the relationship between the time of evolution of effusion and structural changes of mucoperiosteum are related [4]. In this context, we should regularly follow up patients who are having OME and likely to have OME because of very frequent URTI (Figure3).…”

Otitis Media with Effusion (OME) is a very common disease among catarrhal children of younger age group who are immunologically in the developing stage. At school they are exposed to similar kids of the same age group among whom someone may be having upper respiratory tract infection. It may be thus shared among them in crowded class rooms. Disease remain asymptomatic due to absence of ear symptoms other than mild hearing loss. Thus, it may remain unnoticed. Only intelligent parents or teachers notice it. Those self-resolving, due to high prevalence of the disease, a lot of them go in for sequelae like atelectasis, adhesive otitis media, ossicular erosion, posterosuperior retraction pocket and finally cholesteatoma. Hence in ears which are not picked up early it may be a silent killer of middle ear.

“…24 In human beings and dogs, CG and ear cholesteatoma may coexist. 21,24 Cholesterol granuloma of the middle ear has been experimentally induced in several species of animal including cats, 7,10 chinchilla (Chinchilla lanigera), 10 and squirrel monkeys (Saimiri spp.). 9 In these previous experiments, obstruction of Eustachian tube alone 9 or along with tympanic membrane perforation with or without introduction of foreign material in the middle ear 7,10 was used to successfully induce CG formation.…”

“…Cholesterol granuloma formation was experimentally induced in the tympanic bullae of cats, 7,10 and has been experimentally induced in cats through eustachian tube obstruction leading to middle ear effusion with evidence of organization of the inflammatory effusion within 3 months. Organized effusion in the presence of inflammation and mucosal epithelial lining breaks was considered a potential source for granulation tissue formation and CG.…”

“…Organized effusion in the presence of inflammation and mucosal epithelial lining breaks was considered a potential source for granulation tissue formation and CG. 10 In another similar experiment, tympanic membrane perforation followed by eustachian tube obstruction was induced in cats. Massive reaction of the mucosal periosteum with granulation and polypoid tissue formation and CG, with the classic characteristics as described in human beings, were also observed within 3 months.…”

An 8-year-old, male neutered Siamese cat was presented with Horner syndrome and right head tilt. A soft tissue mass was observed in the right tympanic cavity, and bulla osteotomy was performed. Tissue samples retrieved from the tympanic cavity were sent for histology, and a middle ear fluid swab was sent for bacterial culture and sensitivity. Histologic diagnosis was of otitis media associated with cholesterol granuloma (CG). Bacterial culture yielded Pasteurella multocida and Leifsonia (Corynebacterium) aquaticum. Middle ear CG is frequently seen in human beings and is associated with a variety of middle ear diseases including otitis media. Cholesterol granuloma of the middle ear has been experimentally induced in cats. The clinical and pathological findings of a spontaneous case of CG in the tympanic cavity of a cat with otitis media are described herein.
