Complications of allergic rhinitis

① bronchial asthma Less than half of the hay fever patients and some perennial allergic rhinitis in patients with bronchial asthma, This is due to allergic bronchial lesions result of its sensitized also consistent with allergic rhinitis. Usually in the nose, eye symptoms only after a few years of bronchial asthma, asthma attack before continuing, Persistent cough, which is the precursor symptoms of asthma, allergic bronchitis induced by. A very small number of patients with asthma and nasal and eye symptoms at the same time, a small number of children to asthma. Often found in children, a few years away nasal symptoms of asthma at this time may still attack, it may not have the clinical manifestations. Bronchial asthma is mainly expressed in a breath of breathing difficulties, and Wheezing Music; with serious chest tightness, not supine. Sit often take place or semi-sitting position to help breathing. To remove the viscosity of bronchial secretions, patients often been forced to cough, so children can be caused vomiting. When asthma began ease, often white present phlegm, dyspnea then lifted. Long-term asthma attack can be complicated by emphysema and pulmonary heart disease, patients with serious impact on the health and quality of life, which found only perennial allergic rhinitis. ② otitis media Because of swelling or edema of the nasal mucosa and the eustachian tube row, the eustachian tube the same mucosal lesions can also occur. When the pharyngeal mucosa tympanic membrane swelling and edema reached a certain extent, it can lead to the eustachian tube obstruction, middle ear effusion, and a conductive deafness, which is allergic otitis media. Not suppurative disease, it will not lead to the tympanic membrane perforation and ears discharging. Of its sensitized consistent with allergic rhinitis, allergic rhinitis with allergies otitis media is not common. ③ sinusitis Because of swelling or edema of the nasal obstruction in the nose and nasal Road was due to the sinus openings. Almost all patients with allergic rhinitis have different levels of allergic sinusitis, sinus invasion of regular bilateral, all sinuses. Allergic sinusitis in the absence of secondary infection, often without obvious clinical manifestations, diagnosis relies on sinus x-radiography or cT scanning. ④ other Also in children with allergic rhinitis, nasal blockage due to the long, often caused by mouth breathing can maxillary hypoplasia, zygomatic arch not obvious and looked more, said Adenoidectomy face (as a result looked more adenoidal hypertrophy, long-term blocked choanal named after due). Because pediatric patients with nasal blockage, commonly used in hand to push on the nasal tip in the nasal dorsum forming a rampant fold, saying allergic nasal fold. Some patients with allergic rhinitis, including adults and children, the risk that beneath the blue plaque, or a and allergic "colored" and this is because long-term nasal and sinus mucosa swelling or edema, oppression of the vein, lead venous drainage caused by the disruption.
