Aural polyps are the result of chronic inflammation of the middle ear or mastoid. As seen clinically, polyps represent granulation tissue or edematous mucosa arising from the mucous membrane of the middle ear protruding through a perforation in the …

The oral mucosa is an immunocompetent site [3,31] that displays lymphoid tissue foci where antigen-presenting cells (APCs) and lymphocytes co-localized in the lamina propria [1,3,31]. In homeostatic conditions, the lamina propria harbors small numbers of lymphocytes and dendritic cells (DC), which can become the dominant cell type in chronic ...

2025年1月8日 · Aural polyps are usually reddish, smooth mucosa-covered, painless lesions that originate from the middle ear and protrude into the external ear canal. There is usually a condition that causes chronic irritation in the middle ear, such as chronic otitis media or cholesteatoma.

early may cause morbidity and mortality. Majority of the aural masses presenting as aural polyps can be managed by simple aural polypectomy, while others may need extensive surgical intervention. Those that arise from inflammatory ear diseases are more difficult to manage and are also associated with grievous consequences [2].

An aural polyp (AP) represents a polypoid, non-neoplastic proliferation of inflamed granulation tissue arising from damaged middle ear mucosa that may be lined in part with epithelium exhibiting reactive changes.

2016年1月1日 · Inflammatory (aural) polyps are polypoid edematous inflamed mucosa lined by middle ear epithelium composed of cuboidal, low columnar (ciliated or non-ciliated), or metaplastic squamous epithelium. The inflammatory cells comprise of plasma cells, lymphocytes, and macrophages (Fig. 1).

2016年1月1日 · Aural polyp; Inflammatory aural polyp. This lesion is an inflammatory polypoid proliferation originating from the middle ear mucosa, secondary to chronic otitis media. The precise incidence is not known. Otic polyps may occur at any age, but they arise most frequently in children. These lesions have no sex predilection.

Oral mucosa refers to the tissue lining inside the mouth, which shares similarities with the skin in terms of structure and function. It is exposed to various substances due to its location near the digestive and respiratory tracts, making it a unique site with distinct absorption characteristics and microorganism flora.
