After maxillary sinus polyp and histological differences between normal nasal


Hormone to be effective in reducing eosinophils in nasal polyps and the selective inhibition of aggregation. Also shows that the incidence of allergy and nasal polyps correlated. The pathogenesis of ACP is not clear, the traditional view that learning in the organization with the NIP is the same. That the blow had on the nose, nasal and sinus wash-blown sheets and other physical factors that cause the nasal sinus polyps into the theory, was also reported that the developmental disorder, submucosal gland enlargement secondary to cyst formation and rupture sinuses within the cyst wall of the expansion of the formation mechanism as the ACP, but recently the formation of nasal polyps is not so much that the glandular structure of the expansion, not as a result of hypertrophy of respiratory epithelial edema results. This surface coating was observed in nasal pseudostratified ciliated epithelium. Part of the region shows squamous metaplasia and epithelial shedding, basement membrane thickening. Lamina propria distribution of blood vessels and glands, significant stromal edema is one of the pathological changes associated with eosinophil infiltration, glandular expansion; and ACP of the coating was no difference in epithelial and NP, the main difference is that inflammatory cells infiltration than the infiltration of eosinophils, and almost no submucosal glands, mainly for respiratory epithelial edema rather than gland expansion. Nasal polyp formation is generally believed that the special order of the epithelial cell desquamation, epithelial glands with students and the formation of tiny cavities, ACP group, the scarcity of submucosal glands and general description of the pathophysiology of nasal polyp formation activities almost no relationship between. In addition,[link widoczny dla zalogowanych], in the sections that appear on the skin hypertrophy ACP group was also less than the NP. Description In addition to infection and allergy, but still there is a third factor may be involved in the pathogenesis of ACP. According to a qualitative change in nasal polyps can be asked is divided into four types: edema: the interstitial edema is characterized by a high degree; gland type: mainly for the expansion of mucous serous gland hyperplasia; vascular type: performance as vascular proliferation and expansion; fiber types: the inter- Edema is the main quality of fibrosis was not obvious. In this article edema NP group accounted for 70 cases (92.3%), ACP group, accounting for 3o fiber type (75%), suggesting that ACP group fibrosis was significantly, and its firm texture and is consistent with it, its occurrence may be related to The innate characteristics related to violence may be eel in choanal polyp epithelium activated fibroblasts secondary lower due to that need further study. In summary, the authors suggest that the incidence of nasal polyps associated with a certain allergy, and ACP of the skin inflammatory cell infiltration and fibrosis that is closely related with the infection, it is not in favor of the ACP in the treatment of hormone treatment, complete resection and adequate drainage can achieve satisfactory results.
