变应性鼻炎的病因学 内在因素──遗传因素:有家族史者较无家族史者发病危险高2~6倍母系第11对染色体长臂q段 外在因素(环境因素):基因表达受非遗传因素影响。7000对孪生儿,同时有AR 症状者为21% 易感个体在一定环境条件作用下才发病
发病机制 变应原与致敏靶细胞表面IgE结合 致敏靶细胞脱粒、释放、合成生物活性介质 肥大细胞 嗜酸/碱性粒细胞 储备的介质 新合成的介质 组胺 缓激肽 白三烯 血小板活化因子 前列腺素D2 毛细血管扩张、通透性增加,腺体分泌增多 鼻炎 哮喘
Pathology: Type allergy Allergic inflammation: Predominant T cells & eosinophilic cells infiltrate.
Symptoms & Signs: Nasal irritation and iching recurrent attacks of paroxysmal sneezing copious watery rhinorrhea nasal obstruction
Diagnosis: 1、History(allergen exposure, hypersensitivity, family history) 2、Examination 3、Skin test: skin prick test 4、IgE antibody,Serum total IgE 、special IgE 5、Nasal provocation or nasal chanllenge tests

Complications: 1、Allergic sinusitis 2、Asthma 3、Secretory otitis media 4、Allergic pharyngolaryngitis Treatment: 1、Avoidance
2、Drugs 1)Antihistamines 2)Corticosteroids 3)Sodium cromoglycate(SCG) Cromolyn sodium 4)Anticholinergic agents 5)Vasoconstrictor sympasthomimetics 3、Hyposensitization 4、Others:Traditional Chinese medicine, laser, operation
Nasal Polyp & Nasal Polyposis Etiology:mutilfactors 1.allergic;2.chronic inflammation Pathology:highly swelled connective tissue. Predominant eosinophilic cells infiltrate. Lymphatic cells, neutrophils, basophils, mast cells.
Symptoms & Sign:persistent nasal obstruction,close nasal sound,hyposmia, rhinorrhea, snore, “frog nose” Polyp in maxillary sinus(L),polyp in middle meatus(R)
Diagnosis: Anterior rhinoscopy:translucent, soft, smooth masses. Endoscopy, X-ray and CT scanner. Differential Diagnosis: Papilloma inverted,angiofibroma of nasopharynx,malignant tumor of nasal cavity,meningoencephalocele Treatment:1、conservative treatment——corticosteroids 2、surgical treatment
Sinusitis Acute suppurative sinusitis Features of sinus anatomy: 1、small ostia of the sinuses; 2、continuative mucosa between nasal cavity and sinuses; 3、contiguous of the ostia; 4、location of the astia and features of the sinuses.
Frontal Sinus Ethmoid Sinus Maxillary Sinus
Etiology: 1、General factors: Poor general health (influenza, measles, whooping cough…) 2、Local factors: Sinus diseases; Infective focus of eripheral organs, Direct infection; Nasal tampon (packing); Rapid change of atmospheric pressure
