(1) Recurrent parotitis is probably caused by a congenital abnormality of the salivary gland ducts with recurrent attacks of ascending infection, perhaps aided by dehydration. The parotid gland is predominantly affected probably because of its lower rate of secretion compared with the submandibular gland. (2) The condition mainly affects children between the ages of 3 and 6, with males being more commonly affected. The symptoms peak in the first year of school, and usually, but not invariably, begin to subside at puberty. By the age of 22, most patients are completely symptom-free. When the disease starts after puberty, females are predominantly affected. (3) Ultrasound is the appropriate initial investigation, and is usually supplemented by sialography. The sialography may itself cause a resolution of symptoms. (4) Treatment is conservative in the first instance, and an expectant policy is indicated. More aggressive treatment is justified only for those adults with persistent problems. This may be parotid duct ligation, parotidectomy, or tympanic neurectomy, depending upon the preference and experience of the treating physician. 相似文献
